Abstract
The invention provides a space composite supporting structure. The space composite supporting structure comprises hollow perforated piles vertically arranged in a slope body. Open holes are radially formed in the perforated piles and face the side, close to a road, of a foundation pit. The space composite supporting structure further comprises anchor rods and supporting pile bodies arranged on the side, close to the road, of the foundation pit. The tails of the anchor rods penetrate through the open holes, the heads of the anchor rods penetrate through anchor plates to be fixedly arranged on the supporting pile bodies, the tails, penetrating through the outer ends of the perforated piles, of the anchor rods are columnar. Columnar holes are axially formed in the tails of the anchor rods. By means of a pile-anchor combined pouring mode that slurry is injected downwards from openings in the upper ends of the perforated piles and slurry is injected into the columnar holes, the anchor rods are fixed to the perforated piles, and the space composite supporting structure is formed through the combined effect of the perforated piles, the anchor rods and the supporting pile bodies. The perforated piles provide anchoring points for the anchor rods and meanwhile bear the soil pressure behind the piles, soil pressure needing to be borne by an existing supporting structure is reduced, and therefore the slope body is protected against a buckling failure.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention 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.
