Abstract
The present invention discloses a technique for constructing a pre-displacement supporting pile used for supporting a side slope. Holes are drilled in the position of the side slope to be supported, then flexible buffer materials are filled in the holes, and finally the reinforcement concrete is cast in the space of the holes without the flexible buffer materials, the supporting pile is composed of a concrete pile body and a flexible buffer pile body which are close to each other, and steel bars are arranged in the concrete pile body. The present invention has the advantages that when the present invention is used for supporting the side slope, the sliding force of materials behind the pile (rock mass or soil mass) is firstly resisted by the anti-sliding force of the materials; in the process, the side slope body requires the definite displacement, when the displacement reaches the permitted value, namely, when the anti-sliding capacity of side slope materials reaches the threshold, the flexible material part in the pre-displacement supporting pile allows displacement of the side slope body to finish at once; the reinforcement concrete pipe body starts to exert function at once, namely, the sliding force part of the side slope body materials, which is not counteracted by the anti-sliding force is borne by the supporting pile.
Description
Technical field
The present invention relates to a kind of support process and utensil, especially a kind of technique for constructing pre-biased support and the soldier pile thereof that can give full play to side slope material (as the rock on rock slope and the soil body of slight slope, down together) self carrying potential.
Background technology
The soldier pile overwhelming majority that is used for slope retaining at present all is a reinforced concrete pile, reinforced concrete pile intensity height, and rigidity is big, be used for slope retaining and can obtain good effect, but this type of cost is higher.Tracing it to its cause mainly is that this type of stake is used for supporting, and significant feature keeps a back side slope body static exactly, makes it not produce any displacement.In fact for the rock mass or the soil body, the ability that the opposing slippage is just arranged itself, but the performance of this ability needs it that certain displacement is arranged, as long as deformation displacement is within the range of permission, it is still more considerable that the antiskid of side slope body material self moves ability, can utilize fully.But be based on the supporting pattern of at present general " confronting the tough with toughnees ", the antiskid ability of moving of side slope material self is not utilized effectively, and has caused very big waste.
Summary of the invention
The invention provides a kind of technique for constructing pre-biased support and soldier pile thereof that can reduce support cost, the present invention can give full play to the ability that side slope material self antiskid moves.
The present invention adopts following technical scheme:
Technology of the present invention, that is: a kind of pre-biased support pile constructing process that is used for side slope is carried out supporting is holed in supporting place for the treatment of of side slope, and the flexible buffer material is set in this hole then, at last, steel concrete is built in the space in the hole beyond the flexible buffer material.
Soldier pile of the present invention is made up of the concrete pile body and the flexible buffer pile body of phase closing on the position, is provided with reinforcing bar in the concrete pile body.
Compared with prior art, the present invention has following advantage:
When the present invention is used for slope retaining, the sliding force of material after stake (rock mass or the soil body) is at first resisted by the anti-skid force of material itself, this process side slope body needs certain displacement, when this displacement reaches License Value, that is the antiskid ability of moving of side slope material self is when reaching capacity, the also end immediately of displacement of flexible material in the pre-biased support stake part institute side slope body that allows generation, the steel concrete pile body begins to play a role immediately, that is the anti-skid force of the side slope body material sliding force that is not enough to offset itself is partly transferred to soldier pile and born.In other words, use of the present invention, the sliding force that makes original side slope body by present whole bear to change to by soldier pile by the soil body and soldier pile bear jointly.Can save considerable construction cost.

The specific embodiment
A kind of pre-biased support pile constructing process that is used for side slope is carried out supporting, supporting place for the treatment of in side slope is holed, the flexible buffer material is set in this hole then, at last, steel concrete is built in the space in the hole beyond the flexible buffer material, in the present embodiment, the boring back is axially placed dividing plate earlier in the hole, filling flexible padded coaming in the space adjacent that surrounds by dividing plate and hole wall again with side slope, at last, build steel concrete being surrounded in another space by dividing plate and hole wall, above-mentioned flexible buffer material can adopt regular-type foam or be formed by the liquid foaming material foaming.
A kind of soldier pile that is used to implement above-mentioned technique for constructing pre-biased support, concrete pile body 1 and flexible buffer pile body 2 by phase closing on the position are formed, in concrete pile body 1, be provided with reinforcing bar 4, be provided with dividing plate 5 between concrete pile body 1 and flexible buffer pile body 2, above-mentioned flexible buffer pile body can adopt regular-type foam or be formed by the liquid foaming material foaming.
Claims (3)
1. pre-biased support pile constructing process that is used for side slope is carried out supporting, it is characterized in that holing in supporting place for the treatment of of side slope, in the hole, axially place dividing plate, the space filling flexible padded coaming that is positioned at the slope displacement updrift side that surrounds at dividing plate and hole wall then, at last, in another space that dividing plate and hole wall surround, fill and build steel concrete.
2. one kind is used to implement the described soldier pile that is used for side slope is carried out the pre-biased support pile constructing process of supporting of claim 1, it is characterized in that forming, in concrete pile body (1), be provided with reinforcing bar (4) by the concrete pile body (1) and the flexible buffer pile body (2) of mutual closing on the position.
3. soldier pile according to claim 2 is characterized in that being provided with dividing plate (5) between concrete pile body (1) and flexible buffer pile body (2).
