Description
Technical field
The utility model relates to a kind of slope retaining structure, specifically relates to a kind of space composite supporting construction.
Background technology
At present, common slope retaining structure pattern has barricade, anchor pole (rope), shotcrete, campshed or composite construction, and common foundation pit supporting construction pattern has soil nail wall, anchor pole (rope), steel sheet pile, campshed, against making arch wall, diaphragm wall and composite construction etc.But above-mentioned supporting and protection structure all adopts and is implanted into soil nailing, anchor pole (rope) etc. in slope surface supporting and (or) slope, and its influence basin is limited, especially lacks the operative constraint to rear, supporting and protection structure influence area Rock And Soil.Sometimes, may also can for increasing restraint forces to slope body, take to deepen the implantation depth of anchor pole (rope), measure that mechanical type increases a dosage such as a gear volume of concrete, encryption supporting not upgrading, be unfavorable for the material-saving that saves land.Existing side slope, foundation pit supporting construction only pay attention to surface and level to reinforcing, and do not take vertical reinforcement in slope to reinforce, and may cause slope body constraint not and then unstable failure.
Utility model content
The utility model is mainly for solving above-mentioned Problems existing, a kind of space composite supporting construction is provided, slope open interior stake, anchor pole are connected with existing supporting and protection structure three becomes overall, perforate stake assume responsibility for again soil pressure after stake while providing anchor point for anchor pole, reduce the soil pressure that existing supporting and protection structure will be born, thus reach and prevent slope body unstable failure object.
For solving above-mentioned Problems existing, the technical scheme that the utility model adopts is: a kind of space composite supporting construction, comprise the perforate stake of the hollow form be vertically arranged in the body of slope, described perforate stake is radially provided with perforate, described perforate is towards facing road, foundation ditch side, also comprise anchor pole and facing road, the supporting pile body that foundation ditch side is arranged, the afterbody of described anchor pole is through perforate, the head of anchor pole is fixedly installed on supporting pile body by anchor slab, the anchor pole afterbody that described anchor pole wears perforate stake outer end is set to bar shape, and column hole is offered vertically on anchor pole afterbody, inject slurry downwards by the upper end open from perforate stake and in column hole, inject the stake of slurry-anchor combined and build mode, anchor pole is made to be fixed in perforate stake, by perforate stake, the synergy of anchor pole and supporting pile body forms space composite supporting construction.
Further, the aperture of described column hole is the twice of described opening diameter or is greater than twice.
Further, connected by connection beam between stake between described supporting pile body.
The beneficial effect that the utility model brings is:
1, slope open interior stake, anchor pole are connected with existing supporting and protection structure three becomes overall, perforate stake assume responsibility for again soil pressure after stake while providing anchor point for anchor pole, reduce the soil pressure that existing supporting and protection structure will be born, thus reach and prevent slope body unstable failure object, can reduce again with material, save the area;
2, this space composite supporting construction, can retrain " in-built " Rock And Soil very well, can retrain again Nei Zhuan back zone, slope Rock And Soil, thus realize multiple-protection, plays and prevents slope body unstability effectiveness, and can effectively save material, saves the area.

Mark in figure: 1, perforate stake, 2, anchor pole afterbody, 3, perforate, 4, anchor pole bag slurry, 5, anchor pole, 6, anchor slab, 7, supporting pile body, 8, connection beam between stake.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in the figure, a kind of space composite supporting construction, comprise the perforate stake 1 in hollow form be vertically arranged in the body of slope, described perforate stake 1 is radially provided with perforate 3, perforate 3 is towards facing road, foundation ditch side, also comprise anchor pole 5 and at the supporting pile body 7 facing road, foundation ditch side is arranged, connected by connection beam between stake 8 between supporting pile body 7.Existing supporting and protection structure can be stake, barricade etc.The afterbody of anchor pole 5 is through perforate 3, the head of anchor pole is fixedly installed on supporting pile body 7 by anchor slab 6, the anchor pole afterbody 2 that anchor pole 5 wears perforate stake 1 outer end is set to bar shape, and column hole is offered vertically on anchor pole afterbody 2, inject slurry downwards by the upper end open from perforate stake 1 and in column hole, inject the stake of slurry-anchor combined and build mode, anchor pole 5 is made to be fixed in perforate stake 1, around anchor pole 5, form one deck anchor pole bag slurry 4, form space composite supporting construction by the synergy of perforate stake 1, anchor pole 5 and supporting pile body 7.
The aperture of column hole is the twice of described perforate 3 diameter or is greater than twice.Allow anchor pole tail diameter be greater than opening diameter, such slip casting later just can realize anchor pole and pile body combines, and is not easily pulled out perforate and then causes the destruction of anchor point when anchor pole is subject to along the body of rod to power outside soil.
In the body of slope, vertically put into perforate stake, perforate is towards road, foundation ditch side, in position; Face road at slope body, foundation ditch one side level squeezes into anchor pole class, treat that anchor pole afterbody is through stake perforate certain length in slope, in position.Perforate stake and anchor pole roughly the same time carry out duct slip casting, node is formed at tapping, making anchor rod anchored in perforate stake, then facing road, foundation ditch side by anchor rod anchored in existing supporting and protection structure, between such perforate stake, anchor pole, existing supporting three, just having connected into an entirety.Perforate stake bears soil pressure after stake, stops native forward slip after stake, makes anchor pole be anchored at pile body well again for anchor pole provides support, and the pulling force that stake provides can Rock And Soil before restrained pile better, stablizes add a guarantee again for Rock And Soil before stake.So, face road, the Rock And Soil of foundation ditch side be just enclosed in perforate stake, in integral system that anchor pole, now supporting are formed.Pile body shares a part of soil pressure, reduces the soil pressure that existing supporting is born, thus reach material-saving, save land effectiveness.
Acting as of anchor slab: one is the increase in lifting surface area, nut or ground tackle (two kinds of modes of fixing anchor bar) directly do not contact with supporting pile body, and pile body concrete surface stress reduces not easily crushed; Two is anchor poles when being subject to along the body of rod to power in soil, due to the stop of anchor slab, anchor pole not easily die-cut enter pile body cause fastening destruction; Three is to limit nut or ground tackle rotation.
Tapping casting method: when one, selecting hollow bolt, by central duct slip casting, 2 slip castings need not be carried out simultaneously; When two, selecting solid anchor pole, technology is more difficult, because this involves tapping time for injecting problem, be difficult to hold, can first from the slip casting of perforate stake upper end open to a little less than under perforate along, do of short duration stopping, carry out from the hole slip casting of anchor pole hole, tapping to be done and the slip casting of anchor pole afterbody, restart perforate stake slip casting (bolt portion slip casting continuation), injecting slurry to ensure that slurry continuity is stirred before slip casting, continuing slip casting.
