Abstract

The utility model discloses an embedded single-layer basement wood pile compound soil nail wall structure, which belongs to the technical field of a basement soil nail wall structure and comprises a plurality of wood piles arranged in a soil body at the periphery of a foundation ditch and an approach foundation on the soil body at the periphery of the foundation ditch, wherein, the top of each wood pile is provided with a beam; a pulling anchor is connected between the beam and the approach foundation; a plurality of soil nails are arranged among the wood piles; an ejection reinforced concrete wall face is arranged at the surfaces of the wood piles. The embedded single-layer basement wood pile compound soil nail wall structure takes the distribution characteristics of the embedded basement into account, makes full use of the integral pulling and connecting effect of the periphery pile foundation, fully plays the advantages of leading support, underground soil prominence-prevention and the combined support of the soil nail wall, and is the exterior-protected construction suitable for the embedded basement in the soft soil area.

Description

Embedded individual layer basement timber composite soil nailing wall structure
Technical field
The utility model discloses a kind of embedded individual layer basement timber composite soil nailing wall structure, belong to basement soil nailing wall structure technical field.
Background technology
Along with the quickening and the growth in the living standard of Urbanization in China, the parking of residential quarters is very urgent and must properly settle problems.In order to make full use of land resources, embedded underground garage is all adopted in many residential quarters, and promptly part or all of house, sub-district falls within on the basement parking garage top board, and basement sidewall periphery is studded with other houses in the sub-district.Soft clay area, soil property is poor.The most pile foundations that adopt of dwelling house, wherein the stake of prestressing force blank pipe has accounted for significant proportion, and the blank pipe stake is very responsive to soil body sidesway.Therefore, excavate the pile foundation that must protect periphery of embedded basement, control peripheral land movement effectively well.Solve the following several schemes of the many at present employings of supporting excavation of the embedded basement of individual layer: the firstth, put slope or inclined-plane soil nailing wall excavation, its cost is economized, but dangerous, the probability of soil body integral slipping and bottom heave is big.And embedded basement and peripheral pile foundation are at a distance of too near, and the construction plant also is difficult to possess, so the scheme problem is more; Second adopts the cantilever campshed to add the cement mixing pile supporting, and the fender body width is little, can satisfy place and supporting security needs preferably, but the cost height, the pile concrete curing time is long, and is long in time limit.The 3rd adopts the supporting of cement mixing pile composite soil nailing wall, and the fender body width is little, also can satisfy place and supporting security needs preferably.Often do not have omen but brittle fracture appears in agitation pile, and cement mixing pile injection soil nailing will draw the hole earlier, construction is inconvenient, and cement mixing pile also will have certain curing time, and the duration is also longer, and cost is also higher.
The utility model content
Have shortcoming in order to overcome in the above-mentioned prior art, the utility model provide a kind of can effectively control peripheral land movement and duration short, cost is economized, the embedded individual layer basement timber composite soil nailing wall structure of easy construction.
To achieve these goals, the technical scheme that the utility model adopted is: a kind of embedded individual layer basement timber composite soil nailing wall structure, comprise the basis of closing on the timber that is arranged in the foundation ditch periphery soil body and the foundation ditch periphery soil body, the timber top is provided with crossbeam, crossbeam and close on to be connected with between the basis and draw anchor, be provided with soil nailing between each timber, also be provided with on the timber surface layer and spray the steel concrete metope.
Further preferred as such scheme, described crossbeam is steel pipe crossbeam or shaped steel crossbeam.
The described anchor that draws is that reinforcing bar draws anchor or cable wire to draw anchor.
Described soil nailing is steel pipe soil nailing or anchor pole.
The embedded individual layer basement of the utility model timber composite soil nailing wall structure has been considered the characteristic distributions of embedded basement, rationally utilize the integral body of peripheral pile foundation to socket effect, and give full play to the advance support of timber, anti-advantage of cheating subsoil protuberance and soil nailing wall combined supporting, be a kind of space enclosing structure that is suitable for the embedded basement of soft clay area.
Specifically, the utlity model has following advantage:
(1) the timber composite soil nailing wall structure is a vertical cut, and it is little that structure takies width, has satisfied the place demand of embedded garage excavation.
(2) timber has big bending rigidity, and the advance anchor bolt effect is obvious, helps reducing the soil body sidesway of excavation in early stage; Soil nailing can pierce soil layer in the space between timber, made things convenient for the soil nailing construction; Timber gos deep into playing the effect that anti-preferably hole subsoil swells at the bottom of the foundation ditch; The timber selection is common, and injection is simple, and the duration reduces, and cost is economized.
(3) the timber top is provided with to draw anchor and close on the basis and sockets, and has rationally brought into play the whole anti-side ability on peripheral basis, has effectively reduced the whole displacement of supporting.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, the embedded individual layer basement of the utility model timber composite soil nailing wall structure, comprise and close on basis 2 on the timber 1 that is arranged in the foundation ditch periphery soil body 7 and the foundation ditch periphery soil body 7, timber 1 top is provided with crossbeam 6, crossbeam 6 and close on the basis and be connected with between 2 and draw anchor 5, be provided with soil nailing 4 between each timber 1, also be provided with on timber 1 surface layer and spray steel concrete metope 3.
Wherein, crossbeam 6 is the steel pipe crossbeam, also can be the shaped steel crossbeam; Draw anchor 5 for reinforcing bar draws anchor, also can draw anchor for cable wire; Soil nailing 4 is the steel pipe soil nailing, also can be anchor pole.
The embedded individual layer basement of the utility model timber composite soil nailing wall structure is to adopt the following steps construction to form:
1) soil excavation is to closing on basic 2 end absolute altitudes;
2) construction timber 1 forms the timber barricade;
3) build, maintenance close on the basis 2;
4) on timber 1 top crossbeam 6 is installed, this crossbeam 6 sockets by drawing anchor 5 and closing on basis 2;
5) along timber 1 downward stage excavation soil mass of foundation pit, between the timber 1 that excavates out, pierce soil nailing 4, in soil nailing 4, carry out slip casing by pressure;
6) sprayed mortar after on timber 1 surface layer steel mesh reinforcement and soil nailing dowel being set forms and sprays steel concrete metope 3.
