It is provided with male locking device, the male locking device of U-shaped steel is placed in locking device and a female outside two；It is provided with anchor cable hole in the middle of U-shaped steel；
Several W shaped steel plate piles composition closure foundation ditch, the afterbody of anchor cable is fixed on waist rail by anchor cable hole；
Waist rail is placed in the waist rail support inside H profile steel, and waist rail support is left and right combination type, and upper and lower side is provided with draw-in groove, draw-in groove and H
In shaped steel, wing plate coincide, and is fastened with bolt.
Further, the cross section of locking device and a female is C-shaped, and the cross section of male locking device is in O shape.
Further, described anchor cable hole is also can be anchor bolt construction hole, and anchor cable can also be anchor pole.
The invention has the advantages that：
1. form W type with two H word steel and U-shaped steel, fore shaft is connected with male locking device using locking device and a female, counter-bending and anti-
Shearing rigidity is very strong, and bearing capacity is big, 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 constituted, there is very high intensity and rigidity, water-resisting property is good, steel sheet pile junction
Lock is tightly combined, can natural antiseepage, body of wall and there is larger adaptive deformation ability, it is scientific and reasonable for structure, plasticity and soft
Good toughness, structural stability is high, is adapted to the construction such as any size foundation ditch sealing, supporting；Can be according to geology, environment and design will
Ask, the diaphragm wall that W shaped steel plate pile is constituted can use churning oblique pull string data anchor cable, or inner supporting type construction.Have multi-functional, application
Scope is wider.
3. waist rail, waist rail support and the W shaped steel plate pile of varying number according to different size of pit foundation, can be selected, can fit
Answer different geological conditions and soil property, flexible safety, excavation of foundation pit earth volume can be reduced, there is no inner support in pit foundation, conveniently apply
Work, improves work efficiency, and installation and removal are convenient, and time and labour saving is economic and environment-friendly.
4. the combination clip waist rail holder structure adopting is simple, and intensity is big, low cost, high precision, and residual stress is little, need not hold high
Expensive welding material and weld seam detection, save steel construction, cost of manufacture 30% about.Dismounting is convenient, saving of labor, saves time, to mother metal
Lossless.
