Detailed Description

The embodiment is a 4D simulation and optimization method for old power station transformation construction, which specifically comprises the following steps:

and S1, acquiring the point cloud model of the reconstruction object and the reconstruction construction progress plan. In the embodiment, the point cloud data of the modified object is obtained through laser scanning, and the point cloud model of the modified object is obtained through denoising, registration, splicing and other processing.

S2, constructing a BIM model of the modified object based on the point cloud model, wherein the BIM model is composed of a plurality of monomer models formed by BIM monomer modeling, and the monomer granularity of the monomer modeling needs to be converted into monomers according to a construction progress plan.

Generally, the point cloud density of the obtained point cloud model is large, and phenomena such as unsmooth modeling can occur when BIM modeling software is directly introduced into the point cloud model, so that point cloud model rarefying treatment needs to be carried out on the point cloud model in order to improve modeling efficiency, BIM single modeling is carried out by introducing the point cloud model into the BIM modeling software after the point cloud model rarefying treatment, a plurality of single models are formed, the single granularity of the single modeling needs to be single according to a construction progress plan, and a basis is provided for smoothly implementing 4D simulation and optimization 4.

And S3, pairing the monomer model in the BIM with the construction task in the construction progress plan. In order to ensure that the monomer models of BIM monomer modeling correspond to tasks in a construction progress plan one by one, 4D coding assignment of the BIM models needs to be carried out on the models in the BIM monomer modeling, 4D coding is compiled according to different professional coding rules of electromechanical equipment, structures, buildings and the like, and the 4D coding of the models in the BIM monomer modeling is ensured to be unique no matter what coding rule is adopted. Meanwhile, in order to ensure that the construction progress plan can correspond to the model in the BIM single modeling one by one, a 4D coding pairing construction task needs to be carried out on the construction progress plan.

The 4D codes are divided according to the monomer names, the specialties, the floors (elevations), the room/unit numbers/axle network coordinates, the equipment types, the sequence numbers and the like of the BIM model, and a 4D coding rule table is formulated, wherein the coding rules are as follows: [ monomer name ] [ specialty ] [ elevation ] [ room/unit number/axis network coordinate ] [ device type ] [ sequence number ], wherein [ monomer name ] mainly includes: main building (MPH), auxiliary building (VPH), main transformer cavern (TPH), switch Station (SH), central Control Room (CR) and tail gate cavern (PSH), etc., [ specialty ] mainly comprises electric specialty (E), mechanical specialty (M), ventilation and air conditioning specialty (MV), water supply and drainage specialty (P & S), structure specialty (S) and building specialty (A), etc., [ elevation ] mainly distinguishes according to the floor such as first layer (L1), second layer (L2) and third layer (L3) and so on, [ room ] mainly defines and distinguishes according to the function of room, such as electricity distribution room (SR), freezer room (CR), Air Compressor Room (ACR), etc., [ serial number ] is according to the rule of taking equipment as center from low to high, from left to right to compile serial number. 4D code like No. 1 unit of main building electrical specialty first floor technology water supply water filter block terminal: mph.e.l1.01. wfc.01. For the construction and building profession, positioning coding is mainly carried out through an axis network, such as columns/piles, positioning is carried out through coordinate intersection points of an X-axis network and a Y-axis network, and positioning is carried out on beams and walls through the containing ranges of the X-axis network and the Y-axis network, for example, B2B3 indicates that the beams/walls are in the range from B2 to B3. The panels are positioned by the intersection of two diagonally diagonal X-axis and Y-axis nets, as B5C4 indicates that the panels are in the range between B5 and C4. Thus, the 4D code for column number with main building structure professional first floor axis network coordinate C2 is: mph, s, l1, c2, 0 is filled in to keep the length of 4D code at all times, since the structure and construction profession do not contain [ device type ] [ sequence number ].
