Abstract
The present invention relates to building foundation field, the method that specifically a kind of use pile framing shear wall prevents and treats rectangular deep foundation pit quicksand；It is characterized in that：Including step 1, along on the outside of side slope, support pile is set；Step 2, foundation ditch Yield rainfall relation；Step 3, layer and section excavation pit, dig to stopping during drifting sand layer and excavate；Step 4, cushion cap, shearing foundation of wall and shear wall construction；The excavation of step 5, foundation ditch remainder.This construction method around foundation ditch by setting up supporting facility, so that the problems such as slope collapse caused by quicksand is answered in house；Meanwhile, supporting is built by the way of steel reinforcement cage, with adaptable advantage.
Description
Technical field
The present invention relates to building foundation field, specifically a kind of use pile framing shear wall prevents and treats rectangular deep foundation pit quicksand
Method.
Background technology
With the fast development of urban construction, urban land is gradually nervous, and many cities will develop underground space conduct
The emphasis of urban construction.During underground engineering construction, drifting sand layer is frequently encountered.Drifting sand layer can cause substrate soil forfeiture to be held
Loading capability, execution conditions deteriorate, and slope collapse can be caused when serious, or even jeopardize the safety of close to buildings.Conventional quicksand
Prophylactico-therapeutic measures includes：Dry season constructs, beats steel sheet pile, not drainage construction, diaphram wall, well-points dewatering etc., and method is more single,
Applicability is not strong, and Part Methods cost is higher, construction period is longer, and quicksand prevention effect is not good.
The content of the invention
It is an object of the present invention to provide a kind of quicksand prevention when being used for all kinds of excavation of foundation pit and foundation ditch can be effectively ensured applying
The method of work safety.
In order to achieve the above object, the present invention is realized in：
A kind of method that use pile framing shear wall prevents and treats rectangular deep foundation pit quicksand, including
Step 1, along setting support pile on the outside of side slope；
Step 2, foundation ditch Yield rainfall relation；
Step 3, layer and section excavation pit, dig to stopping during drifting sand layer and excavate；
Step 4, cushion cap, shearing foundation of wall and shear wall construction；
The excavation of step 5, foundation ditch remainder.
Signified cushion cap in the method that described use pile framing shear wall prevents and treats rectangular deep foundation pit quicksand, step 4, basis and
Shear wall construction includes
Step 4.1, by cushion cap, shearing foundation of wall, shear wall according to Structural Design Requirement assembling reinforcement and formwork step 4.2, pour
Concrete is built, form removal after concrete reaches intensity requirement；
Step 4.3, after shear wall concrete strength reaches the 70% of design strength, then to remainder excavate.
The method that described use pile framing shear wall prevents and treats rectangular deep foundation pit quicksand, step 2 meaning foundation ditch Yield rainfall relation should
Level of ground water is down to below the absolute altitude 500mm of foundation ditch bottom.
This construction method around foundation ditch by setting up supporting facility, so that house answers slope collapse caused by quicksand etc. to ask
Topic；Meanwhile, supporting is built by the way of steel reinforcement cage, with adaptable advantage.
Brief description of the drawings
Fig. 1 is the construction schematic diagram of this prevention and controls.
Embodiment
The present invention is further illustrated below by way of specific embodiment.
A kind of method that use pile framing shear wall prevents and treats rectangular deep foundation pit quicksand, including
Step 1, along setting support pile 1 on the outside of side slope；
Step 2, foundation ditch Yield rainfall relation；
Step 3, layer and section excavation pit, dig to stopping during drifting sand layer and excavate；
Step 4, cushion cap 2, shearing foundation of wall and shear wall 3 are constructed；
The excavation of step 5, foundation ditch remainder.
Signified cushion cap 2, basis in the method that described use pile framing shear wall prevents and treats rectangular deep foundation pit quicksand, step 4
And the construction of shear wall 3 includes
Step 4.1, by cushion cap 2, shearing foundation of wall, shear wall 3 according to Structural Design Requirement assembling reinforcement and formwork step 4.2,
Casting concrete, form removal after concrete reaches intensity requirement；
Step 4.3, after shear wall concrete strength reaches the 70% of design strength, then to remainder excavate.
The method that described use pile framing shear wall prevents and treats rectangular deep foundation pit quicksand, step 2 meaning foundation ditch Yield rainfall relation should
Level of ground water is down to below the absolute altitude 500mm of foundation ditch bottom.
This construction method around foundation ditch by setting up supporting facility, so that house answers slope collapse caused by quicksand etc. to ask
Topic；Meanwhile, supporting is built by the way of steel reinforcement cage, with adaptable advantage.
