Brief description of the drawings
Fig. 1 is the structure chart of the utility model pile for prestressed pipe.
Detailed description of the invention
The invention provides a kind of construction method of the pile for prestressed pipe based on BIM, implementing before the present invention, first will pass through leadingBore the method for prospecting by boring the geological state of construction is analyzed, by each base pile hole is explored, draw each baseThe log sheet in stake hole, described log sheet comprises borehole coordinate, drilling depth, aperture elevation, retouching stratum soil propertyState, the content such as the layer end degree of depth, lift height, layer end absolute altitude. Then carry out the construction of pile for prestressed pipe by the present invention, concreteComprise the following steps:
A, carry out the construction operation of pile tube, pile tube is pressed in soil layer;
B, according to log sheet, in BIM, input bed thickness and the mechanical property of all kinds of soil layers around pile tube, and set up pipeThe 3D model of stake, the mechanical property of soil layer comprises soil pressure;
C, utilize BIM to provide the internal force analysis figure of every pile tube at different excavating conditions, described internal force analysis figure comprise shear diagram,Bending moment diagram and deformation pattern, the stressed analysis to every pile tube under different excavating conditions, calculates each section of pile tubeMaximum shear value V under different excavating conditionsmax, and draw shearing envelope diagram;
D, according to force analysis, at the shear value V of pile tubemaxThe dangerous section that is greater than V, arranges I-steel, and wherein, V isThe shearing strength of pile tube.
