Abstract

The invention provides a technology for support and protection of a wide-angle steep slope by cable-stayed concrete piles. The technology comprises a vertical pile and cable-stayed piles, and is characterized in that before the vertical pile for supporting and protecting the slope is constructed, cable-stayed piles are constructed in advance for stabilizing the vertical pile, so as to enable a pile system for supporting and protecting the slope to be in the angle-supported stable state, as a result, the technology is suitable for support and protection of the steep slope adjacent to existing buildings, or in the foundation, upper adjacent slope and lower adjacent slope digged in facility positions, road building on the slope surface, house building, or other facilities building. Compared with the prior art, the technology for support and protection of the wide-angle steep slope by cable-stayed concrete piles has the remarkable advantages of small occupied area, high firmness, flexibility in application and the like, so as to have excellent popularization and application values.

Description

Tiltedly draw the concrete pile to protect wide-angle abrupt slope technology admittedly
One, technical field
The present invention relates to construction work, be specifically related to a kind of concrete pile that tiltedly draws and protect wide-angle abrupt slope technology admittedly.
Two, background technology
Follow urban development and social progress, adjoin highrise building, Lin Po building, cut the slope building, wear ridge passage building etc., after engineering is finished in the work progress neutralization, all normal chance does not allow safety to put the slope, need carry out interim or permanent solid bank protection demand, to satisfy the safety of construction and facility.The support forms of soil nailing wall, piled anchor, soldier pile, protective screening and aggregate measures that adopt are disposed more under the prior art, the job practices that multistory reinforced concrete is subjected to force adaptive inner supporting body system also appears in the construction of dell base, these technology and method are all with separately advantage, what guaranteed work progress normally carries out safety with building facilities, but also limited because of problem restrictions such as narrow limited, the cost height in separately inferior position such as firmness, support force, application difficulty, space.
Two, summary of the invention
The objective of the invention is at above problem and shortage, provide a kind of space narrow, wide-angle abrupt slope and the permanent concrete pile that tiltedly draws that protects the abrupt slope admittedly protect wide-angle abrupt slope technology admittedly.
The objective of the invention is to be achieved through the following technical solutions:
A kind of concrete pile that tiltedly draws protects wide-angle abrupt slope technology admittedly, and it comprises staking out and slope bolt piles, it is characterized in that constructing the slope bolt piles of firm staking out before the staking out of constructing solid bank protection in advance; Vertical outwards with the foundation ditch sideline in the foundation ditch edge of setting, bore the reaming hole downwards, the cloth muscle is annotated concrete and is formed slope bolt piles, vertical the boring in foundation ditch sideline beaten staking out hole cloth muscle, staking out and slope bolt piles infall with staking out and the welding of slope bolt piles muscle, tie up and be fluid concrete formation one after the one, the foundation ditch bottom surface is goed deep in its staking out, and slope bolt piles is deeper than staking out.
Level off hilltops build the road, in the paddy ravine or build the road, Lin Po builds a house etc. faces the single face linear ramp, in excavating whole sloping process, arrange by different level with the domatic vertical stake bucket of design and join, the slope bolt piles of pile V-type bifurcated makes slope bolt piles be net structure in domatic parallel views plane.
The concrete pile that tiltedly draws of the present invention protects wide-angle abrupt slope technology compared with prior art admittedly, be applicable to and adjoin that existed building or facility place excavate foundation ditch, Shang Linpo, Lin Po or the domatic abrupt slope of building the road, building a house or building in other facilities are protected admittedly down, it is little to have area occupied, the firmness height, remarkable advantages such as applying flexible, thereby have the excellent popularization using value.
Four, description of drawings
Fig. 1 adjoins the horizontal sectional schematic diagram of existed building for what draw tiltedly that the concrete pile protects wide-angle abrupt slope technology admittedly.
Fig. 2 is horizontal section signal for the Lin Po that tiltedly draws the concrete pile to protect wide-angle abrupt slope technology admittedly builds the road
Figure.
Fig. 3 is for tiltedly to draw the concrete pile to protect the domatic slope bolt piles parallel views distribution schematic diagram of wide-angle abrupt slope technology admittedly.
Among the figure 1, staking out; 2, slope bolt piles; 3 foundation ditches; 4, native stone layer; 5, existed building, 6, escarpment; 7 road surfaces; 8, gutter.
Five, the specific embodiment
Below in conjunction with Figure of description, tiltedly draw the concrete pile to protect wide-angle abrupt slope technology admittedly to further describe below doing to of the present invention.
Embodiment 1: as shown in Figure 1, in foundation ditch 3 constructions of adjoining under existed building 5 situations, do not have or put sloping space very less, foundation ditch 3 edges of setting, the vertical reaming hole of boring outwards, downwards with edge line, the cloth muscle is annotated concrete and is constructed slope bolt piles 2, remove slope bolt piles 2 concrete in foundation ditch 3 edges, indwelling slope bolt piles 2 interior reinforcing bars also bend on one side, bore to beat 1 hole of staking out, cloth muscle and slope bolt piles 2 reinforcing bars and staking out 1 reinforcing bar welded and tie up, concreting forms one, and its staking out 1 should penetrate with the stone layer 4 of not breaking ground of foundation ditch 3 bottom surfaces, and slope bolt piles 2 is deeper than staking out 1.
Embodiment 2: as Fig. 2, shown in Figure 3, in the single face linear ramp, excavate and the ramping process on the formed platform, break slope bolt piles 2 holes, cloth muscle notes concrete with domatic vertical the boring to, V-type bifurcated of design, excavate and ramping finish after build staking out 1, and be connected to build with slope bolt piles 2 and be one.In being applied to the roadside bank protection, should leave the gap between its 7 gutters 8, road surface and staking out.
Except the described technical characterictic of manual, be the known technology of those skilled in the art.

Claims (2)
