Description
Technical field
The present invention relates to the technical field of Geotechnical Engineering, more specifically, relate to the supporting knot of a kind of double steel sheet pile
Structure and construction method thereof.
Background technology
Along with the development of China's skyscraper, traditional single supporting construction can not better meet engine request, double
Campshed building enclosure is widely applied in base pit engineering because it has preferable implementation and achieves good economy, society
Can benefit.General double-row pile many employings cast-in-situ bored pile, cast-in-situ bored pile has that bearing capacity is big, good stability, settling amount are little
Advantage, but there is also complex process, mud rubbish is more, the more high problems of cost.Substantial amounts of case history and theory
Analytical proof, being rigidly connected of campshed stake top is more reasonable than without connecting, and the connected mode on current campshed stake top has many, but
The less stake top connectivity problem relating to double steel sheet pile.Sealing gear can be effectively played by setting steel sheet pile around foundation ditch
The effect of soil, after foundation pit construction terminates, can extract steel sheet pile thus reduce construction cost, but steel sheet pile supporting belongs to soft
Property supporting, when excavation of foundation pit is deeper, steel sheet-pile deformation can be relatively big, although setting double steel sheet pile can reduce Support Deformation, but
Be the percolation path of level of ground water still along front-seat steel sheet pile, the seepage deformation problem of foundation ditch the most effectively solves.
Summary of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art, it is provided that the supporting construction of a kind of double steel sheet pile and
Construction method, the foundation ditch seepage deformation caused with the stake top connectivity problem and excavation of foundation pit solving double steel sheet pile and steel sheet pile become
The problem of shape.
For achieving the above object, the technical solution used in the present invention is: the supporting construction of a kind of double steel sheet pile, including before
Arrange steel sheet pile, heel row steel sheet pile, enclose purlin, draw-in groove, linking beam, bolt, it is characterised in that enclose purlin described in: and the steel sheet pile often arranged is connected
Being connected into an entirety, described draw-in groove snaps at the straight plate in front and rear row steel sheet pile stake top, and align with draw-in groove in the end of described linking beam, steel
Sheet pile, draw-in groove, linking beam all leave bolt hole and are one-time fixed by bolt.
As preferably, described in enclose purlin and use double Pin, be arranged in often row's steel sheet pile near foundation ditch side and slightly above ground.
As preferably, described draw-in groove is U-shape structure, and front and back two interplanar distances are identical also with thickness at the straight plate of institute's card steel sheet pile
And front and back two sides is respectively arranged symmetrically with four bolts hole.
As preferably, described front-seat steel sheet pile, heel row steel sheet pile are U-shaped Larsen steel sheet pile, are disposed with at the straight plate in stake top
Four bolts hole, steel sheet pile bassets 0.5m.
As preferably, described linking beam two ends are all welded with a block plate, and steel plate is disposed with four bolts hole.
As preferably, the position, bolt hole hole on bolt hole, the bolt hole of draw-in groove and the linking beam on described steel sheet pile stake top
One_to_one corresponding, and can be one-time fixed through the bolt hole of three by bolt.
The construction method of supporting construction based on a kind of double steel sheet pile, comprises the following steps:
Step one, according to place and design requirement, determine that the model of front and rear row steel sheet pile, stake be long, array pitch, construction depth,
Select suitably to enclose purlin, draw-in groove, linking beam model and position；
Step 2, heel row of reaching the last steel sheet pile are also set up and are enclosed purlin；
Step 3, snap in stake top draw-in groove so that draw-in groove bolt hole overlaps with steel sheet pile bolt hole；
Step 4, fixing linking beam, be directed at draw-in groove bolt hole by linking beam bolt hole, by screw bolt by steel sheet pile,
Draw-in groove, linking beam are fixed；
Step 5, front and rear row inter-pile soil body carrying out precipitation, inter-pile soil body water level is not less than bottom water position, hole；
Step 6, foundation ditch carrying out precipitation, bottom water position, hole meets design requirement；
Step 7, excavation of foundation pit underground structure of constructing；
Step 8, Underground Construction go out terrace, and after the space between structure and Foundation Pit wall is backfilling and compacted, recovery is enclosed
Purlin, draw-in groove, linking beam also extract steel sheet pile.
The invention has the beneficial effects as follows:
1, the stake top attachment structure of the present invention makes the deformation of before and after's steel sheet pile stake top coordinate mutually.
2, the precipitation of the soil body between the campshed of the present invention, reduces the horizontal force of front-seat steel sheet pile, makes percolation path by edge
Front-seat steel sheet pile to arrive to add at the bottom of foundation ditch and greatly then arrive base by the soil body between at the bottom of steel sheet pile stake front and back via heel row steel sheet pile
The end, hole, thus reduce Support Deformation and seepage flow deformation, improve the safety of excavation of foundation pit.
3, the supporting construction of a kind of double steel sheet pile of the present invention can factorial praluction, the construction period is short, and cost is low, safety
Property high, structure reusable edible.
