Description

Stratum pile foundation construction method based on BIM models
Technical field
The invention belongs to architecture construction, more particularly to a kind of method based on BIM models construction bad ground pile foundation.
Background technology
Building is widely used frequently with stratum pile foundation form, this kind of base form in weak soil property area.Building The design of stratum pile foundation, the detailed geological mapping report of Main Basiss, but detailed geological mapping reports reflected geology Information is more scattered.Exploratory spot is generally selected, each soil thickness information under selected exploratory spot is checked in drilling downward vertically, usually will Exploratory spot thickness information in same vertical section is represented in a figure, by shape after the following soil layer interface point fitting of each exploratory spot Into the cutting plane entirety clay distribution situation, which is, soil layer interface point in sectional view is fitted, by Then two-dimensional space is fitted, then the soil layer information that sectional view used is reflected is more scattered, it is impossible to represent entire construction on-site The continuously distributed situation of three dimensions of same soil layer.
When carrying out stratum Design of Foundation, generally use is exactly detailed exploration report, stratum Design of Foundation foundation Two-dimensional space clay distribution situation designs, so in the design process, secure context is more conservative, and often pile body length in stratum is set That counts is long, buries relatively deep, and safety is preferable but economy is poor, causes a degree of waste of resource, so carrying out ground During layer pile foundation construction, it is necessary to carry out reasonable argument and analysis to the economy of stratum pile foundation used.
1st, such as Fig. 1, general geological information are showed by sectional view, on 1 surface of place ground, beat geological prospecting hole 2, As geological prospecting hole 2 vertically the more is beaten the more deep, geological prospecting hole 2 may pass through various different soils, geological prospecting hole 2 and soil layer circle Face intersects to form crosspoint 3, can be substantially by geological prospecting hole and the soil layer interface crosspoint 3 drawn up a contract on a soil layer face Cutting plane 4 between soil layer interface is fitted, when carrying out stratum Design of Foundation, surveys different geology exploratory holes in report in detail Interface cutting line 4 is two-dimensional signal between the soil layer reflected between 2, fails to reflect each soil layer distributed in three dimensions situation, so When causing stratum Design of Foundation, pile length design in stratum is more conservative, causes the wasting of resources.
2nd, as shown in Fig. 2, general stratum pile foundation generally comprises two parts, soil is squeezed into cushion cap 5 and stratum stake 6, stratum stake 6 In, the load that upper building transmits is supported by stratum stake 6 side frictions and stratum stake end reaction, is actually carrying out ground It during layer pile foundation construction, proposes to optimize bad ground pile foundation using BIM, avoids stratum stake long long as possible, avoid resource mistake Degree waste, energy conservation and environmental protection.
Invention content
In order to solve defect of the existing technology, the purpose of the present invention is to provide a kind of stratum pile length reasonable designs To avoid the stratum pile foundation construction method based on BIM models of construction waste.
The present invention realize above-mentioned purpose the technical solution adopted is that:A kind of bad ground pile foundation based on BIM technology is applied Work method, it is characterised in that step is:(1) acquisition geology exploratory hole and soil layer interface crosspoint information;(2) geological prospecting hole with Soil layer interface crosspoint Three Dimensional Interface between the setting-out of BIM buildings models forms soil layer;(3) overlying soil interface forms whole mould Type;(4) stratum pile foundation threedimensional model is established according to design drawing;(5) pile foundation threedimensional model in stratum imports geological prospecting hole In the threedimensional model formed with soil layer interface crosspoint;(6) longitudinal section method checks Different Strata stake axis view respectively; (7) bearing stratum depth is inserted at stake end in observation stratum, and is analyzed and judged that each stratum stake embedded depth situation is in sectional view It is no reasonable.
Implement technical solution of the present invention, according to the reasonability that design stratum pile body length proportioning is checked in the construction stage, carry Go out the bad ground pile foundation optimized construction method based on BIM technology, using the entire soil layer information of Building Information Model technology, set Count stratum stake long message, the exploratory spot data three-dimensional visual that exploration report is obtained forms the whole three-dimensional boundary of same soil layer Face figure forms entire site soil layers distribution situation.Stratum pile foundation threedimensional model is made using BIM technology, by the stake of design stratum Basic model is imported in entire place threedimensional model, by section method, can check each stratum stake of designed stratum pile foundation Body length whether reasonable design, the construction stage optimize stratum Design of Foundation figure.
Description of the drawings
Fig. 1 is formation information sectional view.
Fig. 2 is BIM model schematic three dimensional views.
Fig. 3 is BIM models section schematic diagram.
In figure:1- places ground, 2- geological prospectings hole, 3- geological prospectings hole and soil layer interface crosspoint, between 4- soil layers Interface cutting line, 5- cushion caps, the stake of 6- stratum, Three Dimensional Interface between 7- soil layers.
Specific embodiment
As shown in figure 3, the stratum pile foundation construction method based on BIM models is:
1st, the detailed geologic information in place is obtained;
2nd, acquisition geology exploratory hole 2 and 3 information of soil layer interface crosspoint;
3rd, geological prospecting hole 2 and soil layer interface crosspoint 3 Three Dimensional Interface 7 between the setting-out of BIM buildings models forms soil layer;
4th, overlying soil interface forms block mold;
5th, stratum pile foundation threedimensional model is established according to design drawing;
6th, pile foundation threedimensional model in stratum is imported in the threedimensional model that geological prospecting hole is formed with soil layer interface crosspoint 3;
7th, longitudinal section method checks Different Strata stake axis view respectively;
8th, bearing stratum depth is inserted at stake end in observation stratum, and analyzes each stratum stake embedded depth situation in sectional view;
9th, judge whether stake 6 insertion bearing stratum depth situation in stratum is reasonable, and then optimization design drawing in design drawing, Construction stage to stake 6 length careful designs in stratum in design drawing, avoids the excess waste of resource.
