Description
Technical field
The invention belongs to building field, especially relate to W shaped steel plate pile structure.
Background technology
Steel sheet pile is a kind of efficient economizing construction timber.Be widely used in the architecture basics engineerings such as harbour, bay, dock, levee revetment, water stop cofferdam, river improvement, embankment reinforcement, retaining wall, waterwall and building foundation pit supporting at home and abroad.
Steel sheet pile construction is simple, can reduce the requirement to space, and the duration shortens.Use steel sheet pile can provide necessary safety and ageing comparatively strong, not by the restriction of weather condition, can simplify the complicated process of inspection material or systematic function, ensure its compliance, interchangeability well, and can be reused.
Deep big foundation pit constructs existing employing inner supporting type: steel sheet pile inner support component is primarily of compositions such as the support of longeron, crossbeam, diagonal brace, counterpart, bracket, set squares.Steel sheet pile inner support, general employing both at home and abroad as shown in Figure 4.
Current bracket (waist rail holder) generally takes welding manner, and before installation waist rail, be first welded on steel sheet pile by waist rail holder (bracket), weld and mother metal adjacent can produce stress and concentrate.In general in the time just easy place concentrated at the stress fracture of the larger external force of applying.
The filling pile construction cost of diaphragm wall is high, long in time limit, needs longer curing time can bearing load after construction, has a large amount of native slag or mud to discharge, have pollution, not environmentally to underground during pore-forming.
Summary of the invention
In order to address the aforementioned drawbacks, realize above-mentioned object, propose W shaped steel plate pile structure and both having can be used for the construction of churning oblique pull string data anchor cable structure, also can be used for the construction of inner supporting structure.
The technical solution used in the present invention is as follows:
W shaped steel plate pile structure, W shaped steel plate pile is combined into a unit group by two H profile steel and a U-shaped steel, described waist rail is placed in H profile steel, U-shaped steel is provided with between two H profile steel, female snap close is established on inside H profile steel bottom flange two, U-shaped steel two outside be provided with public snap close, the male snap close of U-shaped steel is placed in female snap close; Anchor cable hole is provided with in the middle of U-shaped steel;
The closed foundation ditch of several W shaped steel plate piles composition, the afterbody of anchor cable is fixed on waist rail by anchor cable hole;
Waist rail is placed in the waist rail holder inside H profile steel, and waist rail holder is left and right combined type, and upper and lower side is provided with draw-in groove, and in draw-in groove and H profile steel, wing plate coincide, and uses bolton.
Further, the cross section of female snap close is c-shaped, and the cross section of public snap close is O shape.
Further, described anchor cable hole is also can be anchor bolt construction hole, and anchor cable also can be anchor pole.
The present invention has following beneficial effect:
1., by two H word steel and U-shaped steel composition W type, fore shaft adopts female snap close to be connected with male snap fit, and counter-bending and anti-shearing rigidity is very strong, and bearing capacity is large, mechanical performance and good physical performance, and firmly, H profile steel is a kind of economical.
2. with the continuous body of wall that W shaped steel plate pile is formed, there is very high intensity and rigidity, water-resisting property is good, steel sheet pile junction snap close combines closely, can natural antiseepage, body of wall and there is larger adaptive deformation ability, it is scientific and reasonable for structure, plasticity and pliability good, structural stability is high, is adapted to the constructions such as any size foundation ditch sealing, supporting; Can according to geology, environment and designing requirement, the diaphragm wall that W shaped steel plate pile is formed can use churning oblique pull string data anchor cable, or inner supporting type construction.Have multi-functional, range of application is wider.
3. can according to the pit foundation of different size, select the waist rail of varying number, waist rail holder and W shaped steel plate pile, can adapt to different geological conditions and soil property, flexible safety, can reduce excavation of foundation pit earth volume, inner support is not had in pit foundation, convenient construction, increases work efficiency, and installation and removal are convenient, time and labour saving, economic environmental protection.
4. the combination clip waist rail holder structure adopted is simple, and intensity is large, and cost is low, and precision is high, and residual stress is little, without the need to welding material and the weld seam detection of costliness, saves steel work, cost of manufacture about 30%.Dismounting is convenient, saving of labor, saves time, and can't harm mother metal.
