It the utility model is related to a kind of combined type shaped steel PHC pile tube bearing diagonal foundation pit enclosure structures, including three-dimensional shaped steel, junction steel plate, PHC pile tubes, Grouting Pipe, shoe, end socket steel plate, back cover steel plate;Three-dimensional shaped steel passes through junction steel plate and PHC pile tubes are coaxially connected;Three-dimensional shaped steel upper end is fixedly connected with the capping beam in foundation pit enclosure stake top portion;PHC pile tubes lower end is fixedly connected by end socket steel plate with shoe, and Grouting Pipe sets along three-dimensional shaped steel, PHC pile tubes, shoe from top to bottom, and is fixedly connected with three-dimensional shaped steel, and passes through PHC pile tubes, the inside of shoe;Shoe uses inhomogeneous material with PHC pile tubes.The utility model instead of slip casting steel pipe using PHC pile tubes, cost is greatly reduced, simultaneously, position more than bed course substitutes slip casting steel pipe using three-dimensional shaped steel, cost further reduces, because three-dimensional shaped steel has higher stability and reliability, therefore the intensity of whole structure with oblique member can be protected.

Description

A kind of combined type shaped steel-PHC pile tube bearing diagonal foundation pit enclosure structures
Technical field
It the utility model is related to construction engineering technical field, and in particular to a kind of combined type shaped steel-PHC pile tube bearing diagonal bases Pit enclosure structure.
Background technology
In soft clay area, excavation pit need to carry out pattern foundation pit supporting structure, and soft clay area tradition foundation pit supporting method mainly has perfusion Stake, SMW engineering methods, cement-soil wall etc..At present, for needed in bored concrete pile, SMW engineering methods set horizontal support caused by The shortcomings of shoveling is inconvenient, the duration is longer, cost increase, has developed slip casting steel pipe diagonal brace combining structure.Specific method is using note Slurry steel pipe bearing diagonal replaces horizontal support, can avoid using horizontal support, facility of cutting the earth, reduces the duration, reduces cost.
But this structure with oblique member, it is higher to the intensity requirement of steel pipe, when bearing diagonal length reach to a certain degree it Afterwards, the intensity requirement of steel pipe often more difficult satisfaction, cost rise is also resulted in while the intensity of steel pipe is improved, meanwhile, steel For pipe due to material price, cost is also higher.
The content of the invention
The utility model technical issues that need to address are:Prior art is using the slip casting steel pipe of monoblock type as bearing diagonal Foundation pit enclosure structure, but this structure with oblique member, it is higher to the intensity requirement of steel pipe, when bearing diagonal length reach to a certain degree it Afterwards, the intensity requirement of steel pipe often more difficult satisfaction, cost rise is also resulted in while the intensity of steel pipe is improved, simultaneously because The reason for material price, steel pipe cost is also higher, and prior art can not take into account the cost and intensity requirement of bearing diagonal.
The utility model takes following technical scheme:
A kind of combined type shaped steel-PHC pile tube bearing diagonal foundation pit enclosure structures, including three-dimensional shaped steel, junction steel plate 2, PHC pipe Stake 5, Grouting Pipe 7, shoe 6, back cover steel plate 4;The three-dimensional shaped steel passes through junction steel plate 2 and PHC pile tubes 5 and coaxially connected Connect;The three-dimensional shaped steel upper end is fixedly connected with the capping beam in foundation pit enclosure stake top portion;The lower end of PHC pile tubes 5 passes through end socket Steel plate 3 is fixedly connected with shoe 6, and the Grouting Pipe 7 is set along three-dimensional shaped steel, PHC pile tubes 5, shoe 6 from top to bottom, and with Three-dimensional shaped steel is fixedly connected, and passes through PHC pile tubes 5, the inside of shoe 6;The shoe 6 uses inhomogeneity with the PHC pile tubes 5 Material.
Further, the height of junction steel plate 2 is located at the lower section of the bed course of proposed underground structure.
Further, the three-dimensional shaped steel is the H-shaped H profile steel 1 in cross section.
Further, the H profile steel 1 is provided with horizontally disposed sealing piece.
Further, the shoe 6 is provided with injected hole 8, the position of each injected hole is provided with and is used to prevent shoe 6 to be pressed into During silt block injected hole angle bar hangnail 9.
Further, the Grouting Pipe 7 is arranged on by the web of H profile steel 1, laggard through junction steel plate 2, end socket steel plate 3 Enter shoe 6.
Further, the aperture of the injected hole is 10~20mm, and same depth of section sets 2~6, vertical spacing For 100~200mm.
The beneficial effects of the utility model are:
1) foundation pit enclosure stake, three-dimensional shaped steel, PHC pile tubes, shoe is made to together form bearing diagonal supporting construction, foundation ditch bottom surface Three-dimensional shaped steel above has good resistance to compression, bending resistance and resistance to compression tropism energy, the utility model is had preferable stability.
2) inclined support structure of two-part is cleverly used, shoe and three-dimensional shaped steel are metal material, and PHC between the two Pile tube is concrete material, and this design has to take into account to be considered of both cost and intensity requirement.
3) slip casting steel pipe instead of using PHC pile tubes, cost is greatly reduced, meanwhile, the position more than bed course uses three D type steel substitutes slip casting steel pipe, and cost further reduces, because three-dimensional shaped steel has higher stability and reliability, therefore it is whole The intensity of individual structure with oblique member can be protected.
4) it is easy for construction, securely and reliably.
