Detailed description of the invention
With detailed description of the invention, present disclosure is described in further details below in conjunction with the accompanying drawings.
Embodiment 1
Refering to Fig. 1, for a kind of pile reinforced soil retaining wall, framework is on soft soil foundation, and soft soil foundation includes Soft Soil Layer 10 He
Supporting course 12, supporting course 12 is positioned at below Soft Soil Layer 10, and it includes pile tube, cushion cap, beam slab 1, GSZ 2 and vertical retaining-wall 3；
Pile tube includes the first pile tube 4 and the second pile tube 5, and cushion cap includes the first cushion cap 6 and the second cushion cap 7, and the top of the first pile tube 4 is fixed
The first cushion cap 6, the top of the second pile tube 5 is had to be fixed with the second cushion cap 7, by beam slab 1 between the first cushion cap 6 and the second cushion cap 7
Connect fixing；Vertical retaining-wall 3 is fixed on the second cushion cap 7；First pile tube 4 and the second pile tube 5 through assign after Soft Soil Layer 10 to
In supporting course 12, first cushion cap the 6, second cushion cap 7 periphery is filled with backfill soil 11, and the first cushion cap 6 is equal with the top of both beam slabs 1
Being filled with backfill soil 11, vertical retaining-wall 3 bottom is provided with by vertical retaining-wall 3 to the backfill soil being positioned at above the first cushion cap 6 and beam slab 1
The GSZ 2 that 11 directions extend, GSZ 2 is embedded in the backfill soil 11 being positioned at the first cushion cap 6 with both beam slabs 1 top
In.In the present embodiment, the first cushion cap 6 is the most identical with the design of the structure of the second cushion cap 7, it is simple to taking of material；First pile tube 4 with
The structure design of the second pile tube 5 is the most identical, it is simple to taking of material.
First pile tube 4 and the second pile tube 5 assign in soft soil foundation, it is possible to provide enough bearing capacities, support block cob wall, return
Banket 11 load and landing load；GSZ 2 provides enough horizontal resist forces for vertical retaining-wall 3, prevents vertical retaining-wall 3 from occurring
Level is slided or overturns destruction, and ensures the stability in the large of total.
The side being positioned at and backfill the vertical retaining-wall 3 that soil 11 contacts sets and is equipped with drainage network 8；If vertical retaining-wall 3 is provided with
Dry tapping pipe 9, tapping pipe 9 runs through vertical retaining-wall 3 both sides and makes vertical retaining-wall 3 both sides connect.Drainage network 8 can by backfill soil 11 and
The water on ground is drained in time, also avoids the loss of backfill soil 11；Tapping pipe 9 gets rid of water in time.
