Specific embodiment
The preferred embodiment for cooperating schema and the utility model below, it is to reach to make a reservation in fact that the utility model, which is further described,
The technological means taken with novel purpose.
The utility model provides a preferred embodiment, and as shown in Figure 1A, 1B to Fig. 6, the utility model is a kind of pile foundation
Cast-in-place concrete caisson is placed in a foundation pit 10, is from the bottom to top sequentially drainage layer 20, separation layer 30, caisset 40 and pad
Layer is constituted, and the drainage layer 20 is 3-5cm partial size stone, and the separation layer 30 is 200g/ ㎡ specification geotextiles, caisson
Structure 40 includes plank sheathing, square steel tube, round steel pipe, steel sleeve, wherein the size of plank sheathing is 1830 × 915 × 14mm, side
Steel pipe is 40 × 40mm, and as formwork reinforcement secondary joist, the spacing 200mm of each square steel tube, round steel pipe is φ 48mm, as template
Main joist, each round steel tube spacing 450mm are reinforced, steel sleeve is wall thickness 10mm, diameter 800mm, steel bushing bottom of the tube insertion drainage layer
In, the bed course is high design strength concrete (bleed resistance rust concrete is shunk in the early strong compensation of C30P6).
Complete that bottom surveying setting-out, earth excavation, template installation is reinforced, concrete changes after each process such as filling out, basis is cast-in-place
The working procedure and technique of concrete caisson are as follows:
1, catch pit, elevator contour line are released；
2, according to drawing, catch pit, elevator are excavated；
3, it is excavating in the foundation pit completed, filling 500mm high 3cm-5cm stone is as drainage layer 2, stone top, lower section
Geotextiles are laid with as separation layer 3, prevents concrete grout, soil from flowing into stone, influences concrete quality；
