Hold concurrently arc precast pile (1) of stagnant water including being used for the foundation ditch to keep off soil, be connected with I shaped steel (2) of being used for increasing arc precast pile (1) anti side rigidity on the peripheral lateral wall of arc precast pile (1), through being connected fastener (3) connection between arc precast pile (1) and the I shaped steel. Its cross -section of arc precast pile is the arc, and two tip of arc opening part do not set up spill plug -in components (4) and convex plug -in components (5) be connected with adjacent arc precast pile (1). The utility model discloses an anti side rigidity of structure is big, construction speed fast, have concurrently keep off soil with the stagnant water function, be applicable to the great mesh that digs the deep basal pit.
Description
Technical field
The utility model relates to Geotechnical Engineering field, particularly relates to the foundation pit supporting construction that a kind of arc preformed pile and i shaped steel combine.
Background technology
Along with the paces of Urbanization in China are accelerated, the exploitation of the underground space obtain fast development, and foundation depth is also more and more darker, drives the design of its support of deep foundation ditch and construction technology also constantly to develop thereupon.
In each field of civil engineering, base pit engineering soldier pile, slope project slope protection pile and riverbank shore protection stake, often adopt bored pile, but it is slow to there is speed of application in the method, mud emission amount is large, and environment pollution is serious, and the shortcoming such as after concrete perfusion curing time is long; Traditional semicircle piling bar, U-shaped Larsen steel sheet pile or preformed pile, it is less than normal all to there is anti-side rigidity for pattern foundation pit supporting structure separately in it, is out of shape the shortcomings such as excessive, makes it be applicable to surrounding enviroment protection and requires higher and dig dark larger deep-foundation pit engineering and be restricted.
I shaped steel is also referred to as girder steel; the rectangular steel of to be cross section be " work " word shape; its area distributions than moderate, strong code reassignment ratio rationally; and longitudinal bending resistance strong, construct convenient, lightweight and economy is high; but because i shaped steel itself does not have snap close or connector, time separately for foundation pit supporting construction, can only soil be kept off; can not sealing, the requirement of protection foundation ditch surrounding enviroment can not be met.
Summary of the invention
The utility model object is to provide the foundation pit supporting construction that a kind of arc preformed pile and i shaped steel combine.Structure anti-side rigidity is large, speed of application fast, have gear soil and water stopping function concurrently, be applicable to surrounding enviroment protection requires the foundation pit supporting construction that high, to dig dark larger base pit engineering arc preformed pile and i shaped steel combine.
Realize technical solution of the present utility model:
The foundation pit supporting construction that a kind of arc preformed pile and i shaped steel combine, comprise the arc preformed pile (1) for the double sealing of foundation ditch gear soil, the peripheral sidewall of arc preformed pile (1) is connected with the i shaped steel (2) for increasing arc preformed pile (1) anti-side rigidity, arc preformed pile (1) is connected by connection fastener (3) with between i shaped steel.
Further, described its cross section of arc preformed pile is curved, and two of arc opening place ends arrange the spill plug-in unit (4) and convex plug-in unit (5) that are connected with adjacent arc preformed pile (1) respectively.
Further, described spill plug-in unit (4) and convex plug-in unit (5) cooperatively interact.
Further, described connection fastener (3) is U-shaped structure, number at least one.
Further, pile center's spacing of described arc preformed pile (1) is identical with i shaped steel (2) center distance.
Further, the action of described arc preformed pile (1) is 1 ~ 1.2 times of i shaped steel (2) depth of section.
The utility model adopts technique scheme, and compared with prior art tool has the following advantages:
The anti-side rigidity of arc preformed pile and i shaped steel combined foundation ditch support structure is large, and bending resistance is strong, can give full play to the advantage of arc preformed pile and i shaped steel.Both are connected by fastener, the separately construction of arc preformed pile and i shaped steel, continuous productive process.Arc preformed pile and i shaped steel as required, can arrange length flexibly.
Accompanying drawing explanation

Fig. 2 is the gear soil sealing continuous supporting wall schematic diagram that arc preformed pile and i shaped steel combining structure are formed.
Fig. 3 is the foundation pit supporting construction stereogram that arc preformed pile and i shaped steel combine.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail:
As shown in Figure 1, the foundation pit supporting construction that a kind of arc preformed pile and i shaped steel combine, comprise the arc preformed pile 1 for the double sealing of foundation ditch gear soil, the peripheral sidewall of arc preformed pile 1 is connected with the i shaped steel 2 for increasing arc preformed pile 1 anti-side rigidity, arc preformed pile 1 is connected by connection fastener 3 with between i shaped steel.
As shown in Figure 2, the foundation pit supporting construction that the utility model arc preformed pile and i shaped steel combine, its cross section of preformed pile is curved, and two of arc opening place ends arrange the spill plug-in unit 4 and convex plug-in unit 5 that are connected with adjacent arc preformed pile 1 respectively.Described spill plug-in unit 4 and convex plug-in unit 5 cooperatively interact.Two U-shaped connection fasteners can be set between arc preformed pile and i shaped steel, be separately positioned on two ends, junction.Pile center's spacing of described arc preformed pile 1 is identical with i shaped steel 2 center distance.The action of described arc preformed pile 1 is 1 ~ 1.2 times of i shaped steel 2 depth of section.
Based on the construction method of the foundation pit supporting construction that arc preformed pile of the present utility model and i shaped steel combine, comprise the following steps:
The first step: require and computational analysis according to site condition, surrounding enviroment protection, determine that the model of arc preformed pile (1), stake are long, determine the model of i shaped steel, length, spacing;
Second step: according to design length, the width of i shaped steel, arc preformed pile arranges connection fastener (3);
