Abstract
The invention discloses an earth slope grouting reinforcement construction method. The method comprises the steps that firstly, a square grid net diagram is drawn on an earth slope needed to be reinforced according to construction design needs; secondly, ditched are dug and earth is loosened according to the construction design needs, and grooves are dug according to the square grid net diagram; holes are dug in the earth according to the crossed grid points of the square grid; then steel wires are pre-buried into the dug ditches in a vertically and horizontally crossed mode, steel bars are vertically pre-buried in the dug holes, and the steel bars are connected with the steel wires to form a whole through hook rings; straight cement sizing agents are intensively injected into the crossed grid points until the grooves are fully filled; finally, checking is conducted on the square grid structure formed after solidification, and it is guaranteed that the earth stabilizing intensity reaches an satisfied effect. The earth slope grouting reinforcement construction method has the advantages that the construction is easy, no crack exists between the square grid structure formed after the grouting and the original earth, and therefore a water permeation prevention whole body is formed; the square grid structure is a beam-pillar whole body, and the orderliness and the beauty are achieved; the degree of mechanization is high, the construction cost is low, the construction period is short, and the earth slope grouting reinforcement construction method is suitable for the reinforcement construction of earth slopes around mountain roads, railways, bridges and buildings.
Description
Technical field
The present invention relates to the protection of building Soil Surrounding, furthermore relate to the protection of the periphery soil-slope of highway, railway or bridge, particularly relate to the strengthening construction of soil-slope.
Background technology
As everyone knows, and even highway, railway, bridge periphery Sloping field in mountain area, soil property situation is complicated, and slope and land slide landslide phenomenon occurs frequently, especially more when rainy season seeps water.Once there is landslide landslide, not only can obstruction, and the life security of entail dangers to people.In order to reduce consequent loss, must prevent trouble before it happens, needing to carry out soil-slope to reinforce.But, because the destabilizing factor of soil-slope is complicated and changeable, not a duck soup is reinforced to it.The reinforcement means that soil-slope is conventional has the dark bolt anchorage of grid and free stone masonry, sprayed mortar etc.This method not only long construction period, mechanization degree is low, and material delivery is difficult, construction cost is high, and consolidation effect is still undesirable.Therefore, soil-slope strengthening construction is a technical barrier always.Up to now, there is no better solution.
The Chinese patent application part relating to soil-slope reinforcing is at present few, only have No. ZL2010101850611 " a kind of its support reinforcement method of deep soil-slope ", No. ZL2012100875254 " a kind of safeguard structure for reinforcing high liquid limit soil matter side slope ", No. 2012100063942 " stretch-draw self-locking umbrella type anchor and soil-slope reinforcement means ", No. ZL2013104364924 " a kind of method that composite curing agent is reinforced the domatic ecology of soil-slope ", No. 2012201250369, ZL " a kind of safeguard structure for reinforcing high liquid limit soil matter side slope " and No. ZL2014204696953 " reinforcement type soil-slope plants generating apparatus ".Although above patent has it to act on, a strengthening construction difficult problem for soil-slope can not be solved up hill and dale, because the destabilizing factor of soil-slope is a lot, need more to reinforce new technology.
Summary of the invention
The present invention aims to provide a kind of soil-slope construction method for grouting reinforcement, to increase the reinforcing technique scheme solving soil-slope, thus solves the technical barrier of strengthening construction.
For reaching goal of the invention, the soil-slope construction method for grouting reinforcement that inventor provides, comprises the following steps:
The first step, according to working design requirement on the soil-slope needed reinforcement, draws grid figure;
According to working design, second step, requires that ditching is loosened the soil, and digs out groove according to grid figure, require the condition that the hierarchy structure of groove meets design requirement; Object of loosening the soil is in order to cement grouting, and digging groove object is to bury wire rope underground;
3rd step, earth size fixing as required in soft earth, dig pit in the lattice point place intersected according to grid figure; Hole object of digging pit is structural integrity and the steadiness of copying tree root principle to increase grouting band and side slope soil, similarly is one tree after the hole grouting of a hole;
4th step, pre-buried wire rope across in length and breadth in the ditch dug out, vertical embedded bar in the hole of digging out, the top staple for strap of described reinforcing bar, reinforcing bar is connected to become entirety by shackle and wire rope, or reinforcing bar and wire rope are welded into entirety;
5th step, the lattice point slurry filling machine injection straight cement slurry intersected at grid figure is full to groove, and slip casting point is intensive, can not occur fracture;
6th step, grid structure cement slurry being solidified to formation checks, guarantees its solid native intensity; If soil property is too soft, namely increases anchor cable and reinforce, until the solid soil of grid structure reaches promising result.
In the said method first step, the size of described grid figure must be determined according to soil property situation, and common grid size is that length and width are 1500mm.
In said method second step, the width of described groove is generally 300 ~ 500mm, and the degree of depth is generally 200 ~ 500mm.
In said method the 3rd step, described in the diameter of digging pit be 200 ~ 300mm, the degree of depth is 500 ~ 1000 mm.
In said method the 4th step, described wire rope is corrosion-resistant steel wire rope, and described shackle diameter is 100 mm.
In said method the 5th step, described straight cement slurry is employing No. 425 cement plus water mixing, well-beaten slurry.
In 6th step of said method, described cement slurry setting time is 4 hours, and described anchor cable is reinforced as general method.
Inventor points out: the slurry injection technique that the inventive method is taked, be based on the principle of the solid soil of the woods, intersection grid structure is just as the horizontal branch of trees in length and breadth, and wherein vertically pre-buried reinforcing bar is just as the thribble of trees, horizontal branch and thribble form a stable solid soil structure, can guarantee that soil-slope is stablized.The thribble degree of depth can decide according to the soft degree of soil property, can reinforce conbined usage if desired with anchor cable.
The inventive method has the following advantages: in soil-slope ditching, easily construction of digging pit, the grid structure formed after slip casting and the fissureless entirety of original soil property, thus forms the entirety prevented water penetration; Grid structure is that post and beam is overall, neat appearance, just as the solid soil of tree root, is a kind of stereoscopic protective structure; The mechanization degree of the technology of the present invention is high, construction cost is low, the construction period is short, is applicable to the strengthening construction of soil-slope around mountain highway, railway, bridge and construction of structures.
