Abstract
A kind of integrated pile tube dado structure of pattern foundation pit supporting structure precipitation, it is characterised in that：Including lagging pile, breast boards, pile cover, shore beam, lagging pile is hollow steel pipe structure, lagging pile side is provided with precipitation hole, lagging pile and is connected with breast boards between stake, lagging pile top connection pile cover, beam is shored in relative lagging pile top by pile cover, collectively constitutes force structure system.This structure, which can be produced in batches, to be reduced cost, can freely assemble, dismantle, existing equipment support can be reused, and farthest save duration and saving construction cost, because lagging pile, breast boards can remove recycling after construction, without any pollution, environmental requirement is met, the construction period is saved.Construction method is simple and reliable.
Description
Technical field
The utility model is related to civil engineering technical field, more particularly, to a kind of pattern foundation pit supporting structure, the integrated pile tube of precipitation
Dado structure.
Background technology
In urbanization process, underground pipeline project is increasing.At present, foundation ditch lagging pile is in industry and civil buildings foundation ditch
Largely used in construction, mostly mixing pile combination anchor rod construction process.But because mixing pile can be made in work progress with anchor pole
Into leaving, underground is polluted, and mixing pile belongs to disposable consumption with anchor pole, it is impossible to recycle, cause to waste.
In addition, generally, deep foundation pit construction is required for precipitation, and mixing pile combination anchor rod construction process can not play precipitation work
With if running into underground water, in addition it is also necessary to additionally implement precipitation, increase construction period and quantities.
Utility model content
To solve existing foundation ditch breast wall technology defect, the utility model provides a kind of pattern foundation pit supporting structure, precipitation integrated pile tube
Dado structure, can with repetitive cycling using, do not result in any underground and leave, while having precipitation function.
To realize above-mentioned utility model purpose, the utility model provides a kind of pattern foundation pit supporting structure precipitation integrated pile tube retaining wall knot
Structure, it is characterised in that：Including lagging pile, breast boards, pile cover, shore beam, lagging pile is that hollow steel pipe structure, lagging pile side are set
Have and breast boards between stake is connected with precipitation hole, lagging pile, lagging pile top connection pile cover, relative lagging pile top passes through pile cover
Beam is shored, force structure system is collectively constituted.
Lagging pile is divided between some sections, each section along short transverse to be connected by flange, is easy to be assembled into any total length.
Mounting hook or latch on lagging pile, to connect breast boards between stake.
The utility model beneficial effect is：Because lagging pile, breast boards take factory to make, can produce in batches reduces into
Originally, it can freely assemble, dismantle, existing equipment support can be reused, and farthest saving duration and saving construction cost
（The processing and fabricating odd-job phase can be realized with the advance stock of factory, distribute on demand）；Because lagging pile, breast boards can be in constructions
Remove and recycle afterwards, without any pollution, meet environmental requirement；Due to the precipitation hole reserved on the utility model lagging pile and diving
Pump and drainpipe do not need extra dewatering process during collectively constituting precipitation system, foundation pit construction, can save the construction period,
Raise labour productivity, reduce foundation ditch retaining wall cost, realize that foundation ditch retaining wall pure green is constructed.

Embodiment
1-3 is described further to the utility model below in conjunction with the accompanying drawings.
Certain underground cable tunnel engineering, cross section out-to-out is 6 meters X6 meters, 1.5 meters of buried depth, 3 meters of groundwater level depth.
Lagging pile uses hollow steel pipe structure, 1.02 meters of steel pipe cross-sectional diameter, 10 millimeters of wall thickness.Lagging pile is divided into 3 along short transverse
Section, connected between each section by flange, pile cutoff length is respectively 3 meters, 4 meters, 5 meters, 10 meters of total length after splicing.In lagging pile stake
Section side is reserved the water energy seepage flow in precipitation hole, the soil body along height and entered in stake, and precipitation hole is blocked with screen cloth, to filter silt.
Lagging pile implements mechanical hole building, and immersible pump is transferred into a bottom from top before pile cover is installed carries out dewatering operation（In the soil body
Water seepage flow enters in lagging pile, and lagging pile now is equivalent to dewatering well.Silt being taken away together during to prevent that immersible pump from drawing water, being led
Stake bottom soil body is caused to loosen, in advance 500 millimeters of high gravels of backfill, to filter silt）.Longitudinally spaced 4 meters along piping lane of lagging pile
Set, lagging pile is provided with mounting hook, to connect breast boards between stake, pile cover is square, is connected by flange with stake, pile cover
Also implement flange with the support beam in stake top portion to be connected.It can apply after foundation pit construction is finished, during pile pulling in pile cover and rotate, to make
Stake is given birth to local products to be loosened, and is easy to pile pulling.
Concrete construction method step is as follows：
Step 1：First implement first segment sunk pile, using mechanical hole building mode, 1 meter of preboring diameter, deep 5 meters drilling.So
First paragraph pile cutoff hammering 5 meters long is sunk to afterwards retaining wall is carried out in hole,（Because machine drilling is pipe diameter, omited in pile sinking
There is soil compaction effect, when being bored under continuation, retaining wall pile cutoff voluntarily will not come off downwards）Continue drilling with machinery again to go after 4 meters, pass through
4 meters of long stakes of second section are connected by flange with first paragraph, 4 meters of hammer piling, such mode again by the 3rd section of stake it is finished after, return
Fill out 500 millimeters of high gravels.Immersible pump is finally transferred into a bottom from top and carries out dewatering operation, pile cover is installed, stake top branch is installed
Support beam；
Step 2：Start to dig foundation ditch, as excavation of foundation pit is carried out, the mounting hook on lagging pile successively installs breast boards.
In this example, 0.5 meter of breast boards width, therefore excavate 0.5 meter of just one layer of breast boards of installation whenever downward；
Step 3：After the completion of excavation of foundation pit, major project construction is carried out, after finishing, backfill.Bottom breast boards is first removed, then
Bottom is backfilled, successively the backfill of earth-retaining edges of boards is removed on side successively；
Step 4：After foundation ditch backfill, stake top support beam and pile cover are first dismounted, immersible pump is then dismounted, then pull out retaining wall section by section
Stake, difficult for lagging pile pile pulling, pile cover is reinstalled, is reversed by applying at pile cover, lagging pile is given birth to pine with local products
It is dynamic.Or into stake the water filling wetted perimeter soil body, reduce frictional force.Pile pulling backfills soil in stake, and compaction in layers simultaneously.
