Technical field

The present invention relates to technical field of civil engineering, and in particular to a kind of quickly to handle mudstone using weatherability woven bag The Construction of Civil Engineering method that stream, landslide collapse.

Background technique

As global climate warms the getting worse of phenomenon, global diastrous weather be also it is more and more, especially It is in annual rain flood season, the secondary disaster such as mud-rock flow, landslide for causing due to heavy rain, typhoon happens occasionally, to lead It causes highway, railway, bridge impaired, causes traffic jam, seriously affect expanding economy and daily life.Currently, state When inherence encounters such mud-rock flow, landslide, most construction methods is still the traditional operational method of comparison, it is desirable that operation Area is big, and the activity duration is longer, and the construction material that new destruction is also easily caused to environment, and is had, must when locality is not easy to obtain Construction material must be transported from strange land for constructing, and largely effect on project progress.For example, some constructions, which can use in soil, adulterates one The soil cement that quantitative cement obtains is as construction material, but soil cement intensity rises slow, long construction period, and non-shot Body is not suitable for no mould and builds；For another example, some constructions can using mechanical property good, concrete of resistance to erosion as construction material, but Before casting concrete, installation template is needed, after concrete hardening, needs form removal, it is long in time limit, and need a large amount of artificial.

Therefore, it is urgent to provide a kind of Construction of Civil Engineering for efficiently, simply quickly handling mud-rock flow, landslide collapsing Method, work-yard require working area it is small, it is small to the secondary injury of environment, this will after calamity in terms of restoration and reconstruction to Guan Chong It wants.

Summary of the invention

Method of the invention is aiming at the shortcomings in the prior art, and provides and a kind of quickly located using weatherability woven bag Manage mud-rock flow, the Construction of Civil Engineering method that landslide collapses, this method can gather materials on the spot, the operation that work-yard requires Area is small, small to the secondary injury of environment, has the advantages that construction method is simple, project speed is fast, high-efficient.

This method is achieved through the following technical solutions:

It provides a kind of using the Construction of Civil Engineering side that weatherability woven bag quickly handles mud-rock flow, landslide collapses Method, comprising the following steps:

Step 1: construction plan:

The hillside fields first destroyed to mud-rock flow or landslide checks before constructing and engineering survey, measures length, width and height and the angle of gradient Degree, and require gradient vertical height in 11m hereinafter, the gradient is 0~60 degree；

Step 2: equipment, material prepare and move in:

Mechanical equipment (such as excavator, loop wheel machine) and material needed for preparing construction, by quantities calculation soil body stability, soil Stone amount and required woven bag quantity, artificial and material；

Step 3: drainage system:

First the drainage system of project is arranged；

Step 4: excavating, site preparation:

It carries out excavating site preparation ground using mechanical equipment；

Step 5: shape designs and produces:

It is made to designed by the required shape for restoring engineering project；

Step 6: the production of woven bag Sheng Tushi:

The required woven bag for restoring engineering project is carried out using excavator to contain native masonry industry, the woven bag is polypropylene The weatherability woven bag of material, characteristic are as follows:

The warp of wire drawing density, broadwise are respectively 10~20/10cm, and substrate grammes per square metre is 90~250g/m², having a size of length 1.0~1.2m, wide 1.0~1.2m, height 1.0~-1.5, suspender belt 4~8,90% or more woven bag fullness degree requirement, every It is 1~2t that woven bag, which can fill weight, and weatherability service life is 10 years or more；

Step 7: bag body is placed:

The woven bag of native stone sequentially laterally disposed first layer will have been filled；Longitudinal direction side section should be two bags and place side by side；

Step 8: bag body is piled up:

After first layer places, continuation piles up the second layer, third layer until n-th layer, piling up the gradient is 1 in order: 0.5；

Step 9: fill compaction and shape confirmation:

After n-th layer placement is appropriate, whether confirmation shape meets design requirement, fills out certain native stone pressure as needed It is real；

Step 10: completion.

In above-mentioned technical proposal, in step 6, it is that native stone is packed into woven bag to use that woven bag, which contains native masonry industry, the soil Stone includes at least one of rubble, sand or gravel, sand soil and cohesive soil.

In above-mentioned technical proposal, the size and performance requirement of unlike material soil stone are as shown in the table:

Material	Full-size cm	Unit volume KN/m3
			Rubble	Less than 20cm	19~22
Sand or gravel	Less than 20cm	18~20
			Sand soil	Less than 20cm	17~19
Cohesive soil	Less than 10cm	14~18

In above-mentioned technical proposal, the basic foundation requirement of construction are as follows: subgrade friction coefficient μ=0.6, basic adhesion strength C= 0KN/m², holding power is greater than 300KN/m²。

In above-mentioned technical proposal, the weatherability woven bag is the model of Qingdao Pu Lin packing articles Co., Ltd production The woven bag of KR-2BBL.

As a preferred option, the apparent size of weatherability woven bag must meet the requirement of table 1, physical strength and chemistry Performance must meet the requirement of table 2, specific as follows shown:

The apparent size performance requirement of 1. weatherability woven bag of table

Physical strength and the chemical property requirement of 2. weatherability woven bag of table:

Beneficial effects of the present invention:

Of the invention is a kind of using the Construction of Civil Engineering that weatherability woven bag quickly handles mud-rock flow, landslide collapses Method, suitable for constructing to gradient vertical height in 11m or less, the mud-rock flow that the gradient is 0~60 degree or the hillside fields that landslide is destroyed, It is mainly gathered materials on the spot using woven bag, carries out containing native masonry industry by excavator, then by the sequentially heap of the woven bag equipped with native stone First layer, the second layer are built up to n-th layer, and piling up the gradient is 1:0.5；After n-th layer placement is appropriate, whether confirmation shape meets Design requirement fills out certain native stone compacting, to complete to construct as needed；Wherein, which is polypropylene Material, characteristic are as follows: the warp of wire drawing density, broadwise are respectively 10~20/10cm, and substrate grammes per square metre is 90~250g/m², size For long 1.0~1.2m, wide 1.0~1.2m, 1.0~1.5m of height, suspender belt 4~8, woven bag fullness degree requires 90% or more, It is 1~2t that every woven bag, which can fill weight, and weatherability service life is 10 years or more, therefore has excellent weatherability, anti-purple Outer and radiation resistance, can be used for a long time and strong under the special environment conditions such as high fever, severe cold, rainwater, wind and snow, solar illumination Degree can still be maintained 50% or more, long service life；On the other hand, it using above-mentioned weatherability woven bag, can take on the spot Material selects suitable native masonry to be packed into woven bag for construction material and carries out piling up use according to particular requirement, can not only be very big Material construction and transportation cost are reduced to degree, and after engineering, the useful life that woven bag maintains also is 10 years More than, it can be used as permanent work.Compared with prior art, the construction method is simple, the operation that work-yard requires Area is small, small to the secondary injury of environment, fast, high-efficient, the construction material operating feature with long service life with project speed, This is for the restoration and reconstruction after highway (road), embankment, river levee encounter the calamities such as mud-rock flow caused by heavy rain, flood, landslide Aspect, can fast quick-recovery road, and reinforce massif sloping bank, the application value with highly significant
