Abstract

A composite supporting structure of a drainage pipe pile and a soil nailing wall consists of supporting piles, a reinforcing mesh, soil nails and anchor rods, wherein anchor rod holes are arranged in supporting pile bodies, the reinforcing mesh is fixed at the end heads of the anchor rods, the soil nails are arranged on the reinforcing mesh. The supporting piles are vertically arranged, the anchor rods penetrate through the anchor rod holes in the supporting piles and are inserted into a supporting body, the end heads of the anchor rods are fixed by nuts, the reinforcing mesh is fixed on the end heads, meanwhile, the soil nails are struck into the supporting body, the reinforcing mesh is hung on the exposed end heads of the soil nails, finally the concrete spraying operation is carried out on the reinforcing mesh, the reinforcing mesh and the supporting piles form a supporting panel, wherein the anchor rods and the soil nails form an included angle of 30 degrees-35 degrees with a horizontal plane. The supporting piles, the reinforcing mesh, the soil nails and the anchor rods are arranged into a whole body and can be stressed at the same time, so the protection capability of the supporting body is improved, and the number of the supporting piles is reduced at the same time, so the construction cost is saved.

Description

White-out pile tube and soil nailing wall composite support structure

Technical field

The utility model relates to a kind of the realm of building construction, is a kind of white-out pile tube and soil nailing wall composite support structure specifically.

Background technology

Extensively adopt soldier pile or soil nailing wall that excavation slope is carried out supporting at the realm of building construction at present, with protection foundation ditch job safety.For preventing the prop avalanche, soldier pile is generally taked tight setting, though this mode can play good supporting effect, can make the engineering construction cost heighten.The supporting and protection structure that is used for soil excavation and stability of slope of soil nailing wall operation rising in recent years mainly applies to the above foundation ditch of groundwater table, or the foundation ditch after artificial rainmaking; The foundation ditch of this type all belongs to shallow foundation hole, and in deep foundation ditch because rich groundwater makes the friction of soil nailing reduce; And then influence its support capacity; Therefore in deep foundation ditch, then should not adopt the soil nailing wall to carry out supporting, the supporting of more employing soldier piles forms water-stop curtain as supporting and protection structure; Reach the purpose that prevents that prop from collapsing, but this mode will cause directly engineering-built to increase.

Summary of the invention

In order to solve the deficiency of prior art structure, the utility model provides a kind of white-out pile tube and soil nailing wall composite support structure, to be issued to the purpose of saving construction costs in the condition that protection effect of prop is not exerted an influence.

The utility model is realized through following technical proposals: be made up of soldier pile, steel mesh reinforcement, soil nailing and anchor pole; Wherein on the pile body of soldier pile, be provided with bolthole; And on termination point of anchor rod, be fixedly connected with steel mesh reinforcement, and steel mesh reinforcement is provided with soil nailing, and wherein anchor pole is horizontal by 30 ° ~ 35 ° angles; Soil nailing is horizontal by 30 ° ~ 35 ° angles, and steel mesh reinforcement is hung over soil nailing exposes on the termination.The soldier pile vertical ground is provided with during use, and the bolthole of anchor pole from soldier pile passes and insert the prop, and termination point of anchor rod adopts nut to fix; And steel mesh reinforcement is fixed on the termination, simultaneously soil nailing is squeezed in the prop, steel mesh reinforcement is hung over soil nailing expose on the termination; On steel mesh reinforcement, carry out the concrete spraying operation at last; Soldier pile, steel mesh reinforcement, soil nailing, anchor pole form an integral body in the utility model, can be stressed jointly, strengthened protective capacities to prop.

The beneficial effect of the utility model is: not only can play very strong protective action to the shallow foundation hole, and can in deep foundation ditch protection field, when not reducing protection effect, reduce the usage quantity of pile tube; Shorten the support construction cycle, in Excavation Process, form supporting and protection structure synchronously, and need not can construct by dewatering; Practice thrift a large amount of construction costs; Product structure is simple, and easy construction is convenient to promote the use of.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the three-dimensional structure diagram of the utility model.

Fig. 2 implements state plan structure sketch map for the utility model.

Fig. 3 implements the state cross-sectional view for the utility model.

Code description among the figure: 1,1 ', 1 ' ' soldier pile; 2 boltholes; 3 nuts; 4 anchor poles; 5 steel mesh reinforcements; 6 soil nailings.

The specific embodiment

As shown in Figure 1, the utility model is made up of soldier pile (1), anchor pole (4), nut (3), steel mesh reinforcement (5) and soil nailing (6), on soldier pile, is provided with bolthole (2), and wherein bolthole is horizontal by 30 ° ~ 35 ° angles.As shown in Figure 2, respectively soldier pile (1) (1 ') (1 ") is arranged on the foundation ditch edge, anchor pole (4) is pierced into from the bolthole on the soldier pile; and be inserted in the prop of soldier pile rear side; use nut (3) that anchor pole is pinned in the termination of anchor pole respectively, simultaneously steel mesh reinforcement (5) is fixed on the termination point of anchor rod, and many group soil nailings (6) are set on the reinforcing bar wire side; steel mesh reinforcement can hang on the soil nailing termination; wherein anchor pole (4) and soil nailing (6) are all horizontal by 30 ° ~ 35 ° angles, and a certain amount of concrete of spraying on steel mesh reinforcement makes steel mesh reinforcement form one and props up protection slab then.After adopting the utility model fix, steel mesh reinforcement add a protection slab quilt that concrete forms respectively soil nailing and anchor pole be fixed on the prop surface, effectively prevent the prop avalanche.Reduce the usage quantity of soldier pile simultaneously, practiced thrift the engineering construction cost, and in the protection system applicable to deep foundation ditch.

In the utility model implementation process, soldier pile can adopt castinplace pile, also can adopt the pile for prestressed pipe piling construction, and wherein pile for prestressed pipe can further reduce the lateral deformation with the non-prestressed structure of diameter, more helps the foundation ditch protection.
