Abstract
The utility model discloses a kind of side slope grouting reinforcement structure, it is drilled with the hole be criss-cross arranged in side slope, in the hole that these are criss-cross arranged, be inserted with grouting tube form network, after being extracted by floral tube after floral tube grouting reinforcement, again linked network reinforcing bar and anchor spraying concrete are set on side slope surface; The described hole be criss-cross arranged comprises vertical hole (1) and horizontal cross hole (2).The novel this structure of ability is by means of being anchored in the soil body after injecting grout through steel perforated pipe, become as a whole after suspended net shotcrete, the pulling force produced sliding area passes to stable region, and then improve the shear strength of soil layer, and the passive earth pressure that reinforcement material can provide by means of soil layer on slide plane, generation shearing and moment of flexure, to resist the slip of active region, reach the object of stable excavation face.
Description
Technical field
The utility model relates to a kind of side slope grouting reinforcement structure, belongs to slope retaining technical field in construction work.
Background technology
The problem of slope retaining is often run in civil engineering, conventional support pattern mainly anchor pole, soil nailing, anchor rope lattice beam, castinplace pile, retaining wall or other combination supporting method, but this kind of support pattern is used for backfill side slope, construction plant is nervous, top, slope (toe) is close to the harsh foundation ditch condition of other buildings (building foundation) and inapplicable, for backfill, above-mentioned support pattern compliance is all poor, and the existence of network of underground also make retaining wall or castinplace pile lack scope for their abilities, therefore, slope retaining problem under the harsh foundation ditch conditions such as backfill side slope still fails to find a kind of technical solution preferably.
Utility model content
The purpose of this utility model is to provide a kind of side slope grouting reinforcement structure, is close to slope retaining problem under the harsh foundation ditch conditions such as other buildings (building foundation) to solve, top, slope (toe) nervous in backfill side slope, construction plant.
The utility model is a kind of side slope grouting reinforcement structure, it is drilled with the hole be criss-cross arranged in side slope, in the hole that these are criss-cross arranged, be inserted with grouting tube form network, after being extracted by floral tube after floral tube grouting reinforcement, again linked network reinforcing bar and anchor spraying concrete are set on side slope surface; The described hole be criss-cross arranged comprises vertical hole and horizontal cross hole.
The principle that general principle of the present utility model and anchor pole stablize the soil body is similar.Namely by means of being anchored in the soil body after injecting grout through steel perforated pipe, become as a whole after suspended net shotcrete, the pulling force produced sliding area passes to stable region, and then improve the shear strength of soil layer, and the passive earth pressure that reinforcement material can provide by means of soil layer on slide plane, generation shearing and moment of flexure, to resist the slip of active region, reach the object of stable excavation face.The uneven soil pressure in active area produced during soil mass of foundation pit excavation is by concrete pavement and steel floral tube anchoring body, finally bear by steel floral tube anchor pole, the pit accident of excavation slope and resistance to overturning also realize the reinforcing of the soil body eventually through steel floral tube, thus solve, slope top (toe) nervous in backfill side slope, construction plant and be close to slope retaining problem under the harsh foundation ditch conditions such as other buildings (building foundation).The utility model structure is simple, and it is convenient to implement, and is worthy to be popularized.

Fig. 1 is vertical hole, wall top arrangement diagram;
Fig. 2 is that wall front level is to hole arrangement diagram;
Fig. 3 is duct, wall side arrangement diagram;
Fig. 4 is slope retaining structure phantom drawing;
Fig. 5 is construction process figure.
The vertical hole of being labeled as in accompanying drawing: 1-; 2-horizontal cross hole.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As Figure 1-4, this structure of the present utility model is in side slope, be drilled with the staggered hole of solid crossbar, comprise the vertical hole 1 and horizontal cross hole 2 arranged in groups, grouting tube is plugged in hole, each duct organizing vertical hole 1 and horizontal cross hole 2 ensures at grade, forms a kind of lattice and supports.First carry out the construction in vertical hole 1 when construction, then carry out the construction in horizontal cross hole 2.
During the utility model construction, as shown in Figure 5, need before construction first to carry out Slope Design and cloth hole, determining hole position and pitch of holes, then carry out being drilled with of vertical hole 1 and horizontal cross hole 2 by group successively.First measurement and positioning during boring, then by place for rig telephone-moving and start boring, after having holed, steel floral tube is stretched in hole, on the other hand simultaneously, water, cement, fine sand are formed slurries after stirring and filtering, and being in the milk to floral tube in the scene delivered to by slurries, extracts floral tube after being in the milk, slurries and slope soil are consolidated, namely complete this hole after reaching design grout standard and construct and carry out next hole construction.This work at grade, forms a kind of lattice and supports.First vertical hole is carried out when construction
Certainly, more than just embody rule example of the present utility model, the technical scheme that the utility model also has other embodiment, all employings to be equal to replacement or equivalent transformation to be formed, all drops within the protection domain required by the utility model.
