Description
Technical field
The utility model relates to a kind of steel sheet pile and pile for prestressed pipe combined foundation ditch support structure and job practices thereof, belongs to the technical field of geotechnical engineering.
Background technology
Retaining Structure with Double-row Piles is meant the parallel stake of two rows is set in foundation soil, two campshed pile bodies rectangular or quincuncial arrangement in front and back is provided with collar tie beam on two campsheds top, and connects with the contact beam, along hole wall parallel direction, form door figure space structure, be the space statically-indeterminate structure, integral rigidity is big, can effectively limit foundation pit deformation, under external load effect complicated and changeable, can adjust the internal force of supporting and protection structure itself automatically, make it to adapt to complicated and often unpredicted loading condition.
Traditional double-row pile generally adopts bored pile.Bored pile has the bearing capacity height, can passing through various soil property complexity or soft or hard, to change big soil layer (as the rock stratum of all kinds of cohesive soils, sand, crushed gravel soil, decomposed rock and many interlayers), construction technology ripe and to advantages such as the surrounding buildings influence are little.But bored pile has, and construction link is more, technical requirements is high, technology is complicated, construction and shortcomings such as curing time length, cost height.
Steel sheet pile as a kind of building material in the bridge construction cofferdam, large-scale pipeline lays, the retaining soil of interim irrigation canals and ditches excavation, dash, the husky wall harbour of retaining, the unloading apron revetment plays a significant role on the engineerings such as retaining wall levee revetment.Steel sheet pile does that the cofferdam is not only green, environmental protection but also speed of application is fast, operating expenses is low, has good water-proof function.In pattern foundation pit supporting structure, also progressively begin in recent years to use.But in general, steel sheet pile supporting and protection structure belongs to the flexible support structure, is out of shape relative campshed supporting and protection structure and wants big.
Prestressed concrete pipe pile is to use more a kind of preformed pile type since late 1980s in China.Advantages such as technology is simple because this type has, reliable in quality, speed of application is fast, cost is lower, easy to detect, thereby in the engineering piles on basis, obtained using quite widely.But pile for prestressed pipe is used less in foundation pit supporting construction because the relative bored pile of anti-horizontal loading is low.
Summary of the invention
The utility model purpose provides a kind of simple in structure, and work progress is simple and efficient, is applicable to weak soil and various soil condition, saves the steel sheet pile pile tube combined foundation ditch support structure of cost.
A kind of steel sheet pile pile tube combined foundation ditch support structure, comprise at the bottom of the face of land behind the wall parallel, the foundation ditch with the face of land, behind the wall at the bottom of the foundation ditch of the face of land between parallel longitudinal arrange front-seat steel sheet pile, back row's pile for prestressed pipe, campshed collar tie beam before the upper end of front-seat steel sheet pile is arranged, the upper end cloth postpone campshed collar tie beam of back row's pile for prestressed pipe, campshed contact beam before and after being provided with between preceding campshed collar tie beam, the back campshed collar tie beam.
The supporting method of steel sheet pile pile tube combined foundation ditch support structure of the present utility model comprises the steps:
The first step: according to site condition and computational analysis, determine front-seat steel sheet pile and back row's pile for prestressed pipe combined foundation ditch support structure, comprise that spacing and array pitch between the pile for prestressed pipe are arranged in the long and front-seat steel sheet pile of stake, a back long, back row's pile for prestressed pipe of front-seat steel sheet pile;
Second step: the front-seat steel sheet pile of constructing;
The 3rd step: arrange pile for prestressed pipe after adopting static pressure construction;
The 4th step: campshed collar tie beam, back campshed collar tie beam and front and back campshed are got in touch beam before the construction respectively;
The 5th step: excavation pit;
The 6th step:, build bed course, construction base plate and agent structure to clearing up, flatten in the end, foundation ditch hole;
The 7th step: backfill, campshed collar tie beam, back campshed collar tie beam and front and back campshed contact beam are extracted steel sheet pile before removing.
The utility model adopts technique scheme, and compared with prior art have following advantage: steel sheet pile of the present utility model can be used as supporting and protection structure, also can be used as water-stop curtain simultaneously, does not have the native problem of stream between stake, is applicable to weak soil and various soil condition; Form space truss structure together with back row's pile for prestressed pipe, integral rigidity is big, can effectively control foundation pit deformation, reduces the pile body moment of flexure.Steel sheet pile and prestressing pipe pile construction simple and fast, easy to control the quality can reclaim behind the steel sheet pile construction, recycle environmental protection.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
As shown in Figure 1, a kind of steel sheet pile pile tube combined foundation ditch support structure, comprise at the bottom of the face of land 6 behind the wall parallel, the foundation ditch 7 with the face of land, behind the wall at the bottom of the face of land 6 and the foundation ditch between 7 parallel longitudinal arrange front-seat steel sheet pile 1, back row's pile for prestressed pipe 2, campshed collar tie beam 3 before the upper end of front-seat steel sheet pile 1 is arranged, the upper end cloth postpone campshed collar tie beam 4 of back row's pile for prestressed pipe 2, campshed contact beam 5 before and after being provided with between preceding campshed collar tie beam 3, the back campshed collar tie beam 4.
