Description
Technical field
The realm of building construction is the utility model is related to, is specially that one kind is applied to small underground garage pattern foundation pit supporting structure, underground
The temporary buildings such as fire cistern pattern foundation pit supporting structure, abutment cofferdam, flood-control intercepting and pipe gallery excavation supporting or part are forever built
Build, the duration that is particularly suitable for use in is tight, low cost, and Deformation control requires the combination steel construction support pile of high base pit engineering.
Background technology
In recent years, as the construction of China hypogee flourishes, the development and utilization of the underground space is increasingly prosperous.With
Land price rises steadily, and the utilization of the underground space all the more urgent, therefore, land red-line is close in the hypogee of planning；
The municipal administration synthesis pipe gallery of planning is located under major urban arterial highway, the scope of pattern foundation pit supporting structure less and less, conventional branch during for excavating
Fender pile, which adds water-seal pile to take up an area width, at least needs 2.0m, plus the operating space of construction machinery, then takes up an area scope and is not less than 5.0m,
The utilization rate in soil certainly will be so reduced, it is less economical.For small underground room or pipe gallery, using traditional bored concrete pile or
SMW engineering methods, not only long in time limit, cost is high, and pollutes environment.Therefore, active demand one kind can meet sealing in base pit engineering,
And can meets earth-retaining, and occupation of land scope is small, cost relatively low supporting construction and construction method.
Number of patent application be CN201220144855.8 utility application disclose a kind of double steel sheet pile with
H profile steel combined foundation ditch support structure.Including for the front-seat steel sheet pile of foundation ditch sealing, the H profile steel for foundation ditch earth-retaining, for auxiliary
Help sealing and heel row steel sheet pile, the fastener of earth-retaining.H profile steel is by two pieces of bodies being arranged in parallel and the company that body links together
Fitting forms, and the outside on body along its length, which is respectively arranged between front-seat steel sheet pile, heel row steel sheet pile, sets fastener.This reality
Though with it is new realize the rigidity of structure is big, have earth-retaining water stopping function, reusable edible concurrently, suitable for cutting depth compared with deep basal pit
Purpose, but still suffer from following deficiency：（1）After double steel sheet pile construction, occupation of land scope is excessive, makes effective use of land rate low；（2）
H profile steel is arranged among two row's steel sheet piles and connected by fastener, and difficulty of construction is larger.Steel sheet pile piling process two campshed position must
It must equidistantly construct, and a little off normal must not occur, otherwise H profile steel can not be inserted in the steel sheet pile of both sides.
Number of patent application is that CN201610481147.6 utility application discloses a kind of I-shaped clad steel
Sheet pile, including Larsen steel sheet pile and I-steel.One side wing edge of I-steel is connected on the web of Larsen steel sheet pile concave surface.This reality
Though with it is new have can rapid construction and the advantages of good water-stagnating effect, there is the advantages of non-deformability is good again, still suffer from as
Lower deficiency：（1）I-steel is connected to Larsen steel sheet pile belly, adds the belly rigidity of steel sheet pile, but Larsen steel sheet pile fastener
Interface rigidity does not increase, then the supporting construction weak link and does not solve；（2）One row's steel sheet pile, can be only formed one of sealing
Act on, after excavation of foundation pit, percolating water situation is more serious.
Therefore, existing just structural support stake is improved, makes its simple in construction, saving building site, and water-stagnating effect is good
Support pile, it has been a good problem to study.
The content of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provide it is a kind of it is simple in construction, save it is for building
Ground, and water-stagnating effect is good, especially suitable for medium and small underground parking garage, can be operated in the construction environment of narrow field
