Abstract
The utility model relates to a steel sheet pile, which belongs to the technical filed of road construction, and comprises straight side steel sheet piles and corner steel sheet piles, wherein the section of the straight side steel sheet pile is a trapezoidal bending, hook heads are respectively arranged on the two ends of the trapezoidal bending, the inner arcs of the hook heads are matched with the sheet thickness of the steel sheet pile, hooked lock mouth sections which are matched with the straight side steel sheet piles on two mutually-vertical directions are respectively arranged on the two ends of sections of the corner steel sheet piles, and hook heads are arranged on the outer end of a lock mouth section, and the inner arcs of the hook heads are matched with the sheet thickness of the steel sheet piles. The steel sheet pile is simple and easy in construction process, is convenient to popularize, and can effectively prevent stopping water and piping. Nearly all supporting facilities can be recycled after being dismounted.
Description
Technical field
The utility model relates to a kind of pattern foundation pit supporting structure facility, and especially a kind of steel sheet pile, belong to technical field of building construction.
Background technology
Complexity day by day along with architectural environment, often run into and wait by the sea bad area to carry out infrastructure.In these " bad " areas, Muddy Bottoms soil enormous amount, and mud is darker, bring challenge to engineering construction---build harbour, road network engineering, bridge tunnel engineering foundation, Tall Building Foundation etc. in soft base and all must pass deep soft base, what kind of digging mode this takes and how to make the Safety assurance measures of digging process is that economy can guarantee speed again, becomes the key subjects of building trade.
The Chinese patent that application number is 201020608527.X has proposed steel sheet-pile cofferdam, with and corner structure, comprise that two block plate stakes for the corner, cofferdam are mutually against placement, its contact site is provided with the connector of fixation steel plate stake, the gap that can prevent junction increases, avoid leaking, the generation of phenomenon, improve cofferdam stabilization.But need welding while connecting, be difficult to dismounting and use again.
Summary of the invention
The purpose of this utility model is: the weak point existed for above-mentioned prior art, propose a kind of not only effectively sealing, prevent piping, construction simply, and the steel sheet pile that can adjust as required, can reuse.
In order to reach above purpose, steel sheet pile of the present utility model comprises straight flange steel sheet pile and corner steel sheet pile; The cross section of described straight flange steel sheet pile is trapezoidal bending, and the two ends of described trapezoidal bending have respectively the gib head that interior circular arc and steel sheet pile thickness of slab match; The two ends, cross section of described corner steel sheet pile have respectively with mutual vertical both direction straight flange steel sheet pile, match hook together the fore shaft section; The outer end of described fore shaft section has the gib head that interior circular arc and steel sheet pile thickness of slab match.
The utility model further improves: the inner of described fore shaft section is connected with C shape corner segments by curved exhibition section.
During construction, the fore shaft of adjacent steel sheet pile fastens mutually, forms cofferdam after squeezing into ground.Because corner adopts the corner steel sheet pile, and, from as whole corner steel sheet pile, forming the fore shaft fastening structure identical with the straight flange steel sheet pile with both sides, therefore take corresponding conventional measure, can guarantee reliable grafting, effectively avoid seepage.Especially, because the fore shaft of the gib head of corner steel sheet pile and adjacent straight flange steel sheet pile forms approximate hinged fastening structure, therefore can be by relatively suitably deflection compensated piling length and steel sheet pile normal width integral multiple poor, very convenient.Simultaneously, the structure of corner steel sheet pile self also can opened up the angle between section by changing within the specific limits C shape corner segments two lateral bendings, further compensation, thus guarantee construction quality, and the remarkable advantage that all can reuse after keeping all supporting facilities to remove.

The specific embodiment
Embodiment mono-
The steel sheet pile of the present embodiment, comprise the corner steel sheet pile 2 shown in the straight flange steel sheet pile 1 shown in Fig. 1 and Fig. 2.The cross section of straight flange steel sheet pile is trapezoidal bending, and the two ends of trapezoidal bending have respectively the gib head 1-1 that interior circular arc and steel sheet pile thickness of slab match.The two ends, cross section of corner steel sheet pile 2 have respectively with mutual vertical both direction straight flange steel sheet pile, match hook together fore shaft section 2-1; The outer end of fore shaft section 2-1 has the gib head 2-2 that interior circular arc and steel sheet pile thickness of slab match.The inner of fore shaft section 2-1 is connected with C shape corner segments 2-4 by curved exhibition section 2-3.
The inner arc radius r of the gib head 1-1 of straight flange steel sheet pile and the gib head 2-2 of corner steel sheet pile equals respectively 1/2nd steel sheet pile thickness t, and the round end that arc radius r equals 1/2nd steel sheet pile thickness t is all made in the gib head termination of straight flange steel sheet pile 1 and corner steel sheet pile 2, therefore the adjacent steel sheet pile not only fits together perfectly after fastening, and has formed local hinged integrated structure.
The adjacent straight flange steel sheet pile in corner steel sheet pile and both sides fastens and forms steel sheet-pile wall as shown in Figure 3.When the integral multiple that runs into piling length non-straight flange steel plate pile beacon 1 accurate width B (or the axis of sheet pile wall is more complicated, the making of steel sheet pile and set error etc.) time, by the developed width B ' of the hinged change straight flange of suitable deflection steel sheet pile and/or expand C shape corner segments by support within the specific limits and adjust the angle a between two lateral bendings exhibition sections, the error of compensating length direction, can as shown in Figure 4, guarantee that the appropriate sealing of steel sheet-pile wall is closed up.
In addition to the implementation, the utility model can also have other embodiments.For example, the inner of two fore shaft sections of corner steel sheet pile also can directly connect by adjacent curved exhibition section 2-3 respectively.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
