Abstract

The utility model discloses a rectangular bored concrete pile that solves the problem of providing a rectangular bored concrete pile that has excellent water stop property, high carrying capacity, simple technique, fast construction speed, low manufacturing cost, and small environment pollution and can carry out continuous work to form a continuous wall. The technical proposal is that: the cross section of the pile is a rectangular, the total length of the pile is 1 to 20m, and the thickness of the rectangular cross section is 0.1 to 0.5m with the width of 0.2 to 1m. The lower end of the pile takes the shape of sharp tip.

Description

The rectangle concrete filling pile

Technical field

The utility model relates to castinplace pile, the rectangular concrete filling pile of especially a kind of cross section.Be applicable to and make foundation in the civil construction project, especially need be at underground build retaining wall.

Background technology

When building is built in soft layer, often need be at underground build retaining wall.Be divided into sheet pile wall, cylinder piling wall and diaphragm wall that retaining wall is at present commonly used, sheet pile wall are owing to be subjected to construction machinery to limit the sheet pile section little, thereby rigidity is also little; Though the cylinder pile section is big, section factor is little when bearing horizontal loading as barricade, and material use is unreasonable; Diaphragm wall because use a large amount of slurry strengthened walls, causes contaminated environment simultaneously then owing to apparatus expensive, cost height.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of have good sealing performance and rigidity is big, supporting capacity strong, reasonable with material, technology is simple, speed of application is fast, low cost of manufacture, environmental pollution are little, can work continuously forms the rectangle concrete filling pile of diaphragm wall.

The technical scheme that the utility model adopted is: rectangle concrete filling pile, its design feature are that the pile body cross section is rectangular.

The utility model pile body length overall 1-20 rice, the thick 0.1-0.5 rice of rectangular cross section, wide 0.2-1 rice.

The pile body lower end is the splitter shape.

The beneficial effects of the utility model are: because its cross section of this cast-in-place concrete pile is rectangular, it is strong, reasonable with material to have favorable rigidity and supporting capacity, do not need main equipment, also needn't use a large amount of slurry strengthened walls, environmental pollution is little, working continuously to make the stake of single rectangle concrete be combined into diaphragm wall or thin diaphragm wall with ribbing, plays and keeps off soil and stagnant water effect preferably.

Description of drawings

Fig. 1 is a stereogram of the present utility model.

Fig. 2 is a kind of implementation method of the present utility model.

Fig. 3 is an another kind of implementation method of the present utility model.

As shown in the figure, the cross section of this routine pile body is rectangular, and long 10 meters * thick 0.2 meter * wide 0.5 meter, the lower end of pile body forms the splitter shape.

A kind of implementation method of the present utility model is at width continous pouring concrete, and the overlapping part of the lateral margin 1-1 of adjacent two piles forms diaphragm wall, as shown in Figure 2.

Another kind of implementation method of the present utility model is the stake of rectangle to be revolved repeatedly turn 90 degrees, and is spliced into diaphragm wall with ribbing, as shown in Figure 3.

Preparation method of the present utility model is: after with vibrating hammer one hollow square shaped steel mould being sunk to the stratum, and perfusion concrete in the mould, vibration is gone up and is dialled punching block then, makes concrete stay the formation rectangle concrete stake the same with the punching block profile in the stratum.The punching block lower end is furnished with band hinge wedge shape valve, and valve closure during the injection stratum forms wedge, squeezes to open the soil body and limit the soil body to enter inner chamber; During molding, valve can squeeze to open under the concrete pressure extrusion and make concrete outflow in the mould, also must rely on vibration to go up during molding dials, the punching block vibration makes concrete be in the stream plastic state, because adjacent two overlapping parts in the concrete pile body edge of a wing, concrete can fully merge in the overlay region, makes a plurality of rectangle stakes synthesize a board wall, and so working continuously just can form thin diaphragm wall with ribbing or not with ribbing.

Claims
