Technical Field

The invention relates to the field of buildings, in particular to a site balancing method.

Background

In the process of building construction, the cost of excavation and filling is increasing with the increase of transportation cost, labor cost and the like.

Disclosure of Invention

The invention aims to provide a method for seeking site balance under the condition of a complex site height difference so as to reduce the construction cost.

The method for seeking the site balance under the condition of the complex site height difference is characterized in that:

step one, calculating the backfill volume L1: l1 ═ H2-H1 × S, where H2 is the design elevation of the outdoor site of the plot, H1 is the balance elevation of the plot before construction, and S is the area of the ground wire of the plot;

step three, calculating the earthing fill quantity L3: l3 ═ G-a × 1.5, where G is the plot area of the plot and a is the building floor area of the plot;

step four, calculating the earth volume L of the land block: and L is L1-L2+ L3, if L is a positive number, the filling amount is represented, and if L is a negative number, the excavation amount is represented.

According to the formula, the earth volume of the land where the building design unit and the construction unit are located can be estimated. Obviously, the design scheme is the best scheme when L is close to 0, so that a building design unit can adjust the design scheme according to the point to make L close to 0, thereby controlling the earth volume of the land parcel at the design source. And the construction unit can determine the amount of the earth moving outside or inside according to the value of L, thereby avoiding the cost rise caused by blind earth moving outside or inside in the construction process.

When the estimation is carried out according to the mapping data and the design drawing, the steps I, II and III have no time sequence, can be calculated at the same time and do not influence each other. Of course, the actual data may be obtained step by step according to the construction process, and because the actual data may deviate from the design data, the step one, the step two, and the step three have a time sequence due to different construction sequences.

Preferably, the shortest distance between the land parcels 1 and 2 is not more than 1000 meters, the construction of the land parcels 1 and 2 is started simultaneously, and the earth volume of the land parcels 1 and the earth volume of the land parcels 2 are positive and negative. Thereby adjusting and transporting earthwork nearby and reducing the earthwork cost.

As another preferable scheme, the distance between the land parcels 1, 2 and 3 is not more than 1000 m, the construction periods of the land parcels 1, 2 and 3 are overlapped, and the sum of the earth volume of the land parcel 1, the earth volume of the land parcel 2 and the earth volume of the land parcel 3 is not more than 2000 cubic meters. Thereby allowing the earthwork to be adjusted and transported nearby and further reducing the earthwork cost. In addition, the direction of earth movement is increased compared to the previous solution, allowing for a partial misalignment of the construction period. Preferably, when block 1 is constructed, block 2 has begun to be excavated and the building on block 3 has been substantially completed.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific drawings.

Referring to fig. 1, fig. 2 and fig. 3, in the method for seeking site balance in the case of a complex site height difference, step one, calculating a backfill volume L1: l1 ═ H2-H1 × S, where H2 is the design elevation of the outdoor site of the plot, H1 is the balance elevation of the plot before construction, and S is the area of the ground wire of the plot; step two, calculating the excavation amount L2 of the ground warehouse: l2 ═ D × G, where D is the basement buried depth of the plot and G is the basement area of the plot; step three, calculating the earthing fill quantity L3: l3 ═ G-a × 1.5, where G is the plot area of the plot and a is the building floor area of the plot; step four, calculating the earth volume L of the land block: and L is L1-L2+ L3, if L is a positive number, the filling amount is represented, and if L is a negative number, the excavation amount is represented.

According to the formula, the earth volume of the land where the building design unit and the construction unit are located can be estimated. Obviously, the design scheme is the best scheme when L is close to 0, so that a building design unit can adjust the design scheme according to the point to make L close to 0, thereby controlling the earth volume of the land parcel at the design source. And the construction unit can determine the amount of the earth moving outside or inside according to the value of L, thereby avoiding the cost rise caused by blind earth moving outside or inside in the construction process.

The equilibrium elevation H1 can be calculated from the data measured by the altimeter.

The equilibrium elevation H1 can also be obtained by: firstly, laying a water pipe pipeline on a land; secondly, taking one end of the water pipe at a high position as an inlet end, taking one end of the water pipe at a low position as an outlet end, putting a vibration ball into the inlet end, and recording the putting time t1 of the vibration ball; then, observing whether the vibrating small ball rolls out at the outlet end, and recording the rolling-out time t2 of the vibrating small ball; then, calculating a time difference t3 between the time t1 when the vibrating ball is put in and the time t2 when the vibrating ball rolls out, wherein the larger the terrain difference is, the faster the vibrating ball moves, and the smaller the terrain difference is, the slower the vibrating ball moves, so that the terrain difference can be estimated according to the time difference t 3; and finally, measuring the height of the outlet end or the height of the inlet end by using a height measuring instrument, wherein the actual height can be obtained by calculating the height of the outlet end or the height of the inlet end by using a time difference t3 coefficient, and then calculating the balance height H1 according to the actual height, and calculating the balance height H1 by using an averaging method. The coefficient is related to the material of the water pipe and the material of the vibration ball. Therefore, the height measurement instrument can be used for measuring the balance height H1 of the position of a water pipeline, the height of the outlet end or the height of the inlet end, and then the coefficient is reversely deduced according to the time difference formed by the vibration small balls on the water pipeline section moving from the inlet end to the outlet end. Note that this method is only applicable to areas with potential differences. And the more pipelines, the more accurate the data. The water pipe is preferably smooth in inner wall to reduce the motion resistance of the vibrating ball. The vibration ball is preferably smooth and spherical in outer wall and internally provided with an eccentric wheel. The vibrating small ball can move and vibrate at the same time, so that the blockage of the pipeline bending to the moving of the small ball can be reduced. The equilibrium elevation is estimated by the time difference between the water outlet time and the water injection starting time at the input time t 1. The larger the difference in the terrain, the faster the water flow rate, and the smaller the difference in the terrain, the slower the water flow rate.

The equilibrium elevation H1 can also be obtained by: firstly, binding a laser range finder on an aircraft, wherein a measuring probe of the laser range finder faces downwards; secondly, controlling the aircraft to fly horizontally above the land to be measured; then, measuring and obtaining the elevation for calibration of a certain place A in the flying process of the aircraft by using a height measuring instrument; finally, according to the measurement data of the laser range finder at the site A, the flight altitude of the aircraft and the elevation for calibrating the altimeter, obtaining a functional relation between the measurement data and the elevation for calibrating; and finally, obtaining actual elevations of more places of the land parcel to be measured according to the functional relation, the measurement data of the laser distance meter and the flight height, and calculating a balance elevation H1 according to the actual elevations. The equilibrium elevation H1 may be calculated by averaging. The method can acquire data of more measuring points in shorter time. The more measurement points, the more accurate the equilibrium elevation H1.

When the estimation is carried out according to the mapping data and the design drawing, the steps I, II and III have no time sequence, can be calculated at the same time and do not influence each other. Of course, the actual data may be obtained step by step according to the construction process, and because the actual data may deviate from the design data, the step one, the step two, and the step three have a time sequence due to different construction sequences.

Preferably, the shortest distance between the land parcels 1 and 2 is not more than 1000 meters, the construction of the land parcels 1 and 2 is started simultaneously, and the earth volume of the land parcels 1 and the earth volume of the land parcels 2 are positive and negative. Thereby adjusting and transporting earthwork nearby and reducing the earthwork cost.

As another preferable scheme, the distance between the land parcels 1, 2 and 3 is not more than 1000 m, the construction periods of the land parcels 1, 2 and 3 are overlapped, and the sum of the earth volume of the land parcel 1, the earth volume of the land parcel 2 and the earth volume of the land parcel 3 is not more than 2000 cubic meters. Thereby allowing the earthwork to be adjusted and transported nearby and further reducing the earthwork cost. In addition, the direction of earth movement is increased compared to the previous solution, allowing for a partial misalignment of the construction period. Preferably, when block 1 is constructed, block 2 has begun to be excavated and the building on block 3 has been substantially completed.
