Abstract
The utility model relates to a floating-resistent structure in the subway tunnel, and provides a gate-shape floating-resistent structure, which is characterized in an uplift pile, a plate of the foundation ditch as well as the connection between the uplift pile and the plate of the foundation ditch in both sides of the subway tunnel. The utility model forms a whole by making use of the uplift pile and the plate of the foundation ditch in both sides of the subway tunnel, and effectively curbs the float in the tunnel due to the removal of the upper foundation ditch when the tunnel is under application and construction so as to safeguard the operation of the tunnel by using the drilling caisson pile as the uplift pile.
Description
Technical field
The utility model relates to and belongs to the subway tunnel float Structure.
Background technology
At present, fast development along with urban construction, need construct at underground tunnel upper, build the sunk type square as needs at underground tunnel upper, after the building completion that the subway tunnel upper is built, the foundation ditch of underground tunnel upper need be unloaded, as do not have reliable measure, to cause the subway tunnel come-up, directly influence the safe operation of subway tunnel.And at present not at the design and construction technology of underground tunnel upper unloading to the tunnel anti-floating, therefore, a kind of foundation ditch unloading of underground tunnel upper is provided after, prevent the float Structure of subway tunnel come-up, be that institute of relevant department is very expected.
Summary of the invention
The utility model technical issues that need to address are to disclose a kind of gate-type float Structure, to satisfy the needs of relevant department.
Gate-type float Structure of the present utility model comprises the uplift pile and the base plate of foundation pit that are arranged on the subway tunnel both sides, and the upper end of uplift pile is connected with base plate of foundation pit.
The utility model forms integral body by the uplift pile and the base plate of foundation pit of both sides, tunnel, can effectively control the tunnel between construction and operating period because of the come-up after the tunnel upper foundation ditch unloading, operation plays a very good protection to tunnel safety.The utility model through test, has fully reflected practicality of the present invention and reliability by the monitored data that subway tunnel is guarded, obtained, and also embodies creativeness and the technological precedence advantage of the utility model in this area.
Description of drawings
Fig. 1 is the schematic diagram of the utility model one embodiment.
Fig. 2 is the schematic diagram of another embodiment of the utility model
The specific embodiment
Fig. 1 is a bored pile gate-type float Structure, and wherein uplift pile is a bored pile 1.Bored pile 1 is arranged on subway tunnel 3 both sides, and stake top reinforcing bar 4 anchors in the base plate of foundation pit 2, and bored pile 1 constitutes integral structure with base plate of foundation pit 2, forms the gate-type float Structure.
According to the preferred scheme of the utility model, the diameter of said bored pile 1 is 600～1000mm, and bored pile 1 length is 10～30m, and bored pile 1 spacing is 2～4m, bored pile 1 is 500～600mm apart from the distance of subway tunnel 3, and the pile body verticality is 1/100～1/300.
Fig. 2 is worker's method stake gate-type float Structure, and wherein uplift pile is an agitation pile 5, agitation pile pile body interpolation H shaped steel 8, and the 8 top shaped steel web perforates of H shaped steel are installed with dowel 9 in the hole, and dowel 9 anchors into base plate of foundation pit 2, forms the gate-type float Structure with base plate of foundation pit 2.2 times soil bodys of base plate of foundation pit adopt cement mixing pile to reinforce, and form to add solid, adopt churning to replenish reinforcing at the soil body that adds between solid and subway tunnel 3 tops.The relative dimensions data of agitation pile 5 are similar to bored pile 1, do not repeat them here.
