Technical Field

The invention relates to the field of underground engineering construction, in particular to a piping emergency drainage tube and a construction method.

Background

At present, in engineering construction, the most worried about during excavation of a foundation pit, a foundation trench and the like is the leakage problem of the foundation pit, so that the foundation pit collapses and is submerged if the foundation pit is light, and the engineering is damaged if the foundation pit is heavy, and the life and property are lost. Among them, piping is the most common form of foundation pit leakage, and its development is rapid and harmful, and if it is not handled in time, it will have serious influence.

The current common treatment method is to adopt filter materials such as gravels and the like to filter and drain the piping position and then adopt water glass constant-speed setting materials to further treat. However, due to the selection of the filtering material and the dispatching of the construction machine, the optimal treatment time is often missed, and the treatment effect is not ideal.

The Chinese patent CN104452828B 'basement ramp piping point drainage and plugging treatment method' comprises the following steps: arranging a section of water filtering steel pipe at the piping opening to serve as a water filtering enclosure well, wherein one end of the water filtering steel pipe is sealed, and the other end of the water filtering steel pipe is reversely buckled at the piping opening point so as to lead all the peripheral water seepage into the enclosure well; one end of a water guide steel pipe is welded on the top of the water filtering surrounding well in a penetrating way; digging a water collecting well outside the width of a construction basement slope, and guiding the piping point seepage water to the water collecting well for collection through a water filtering surrounding well and a water guiding steel pipe; pouring the ramp concrete cushion layer in time after no water is accumulated at the pipe inflow point, and sealing the water guide steel pipe by using a water stop ring steel pipe plug after the concrete cushion layer reaches the required strength; and then binding the reinforcing steel bars on the upper part of the ramp according to a normal procedure, and pouring concrete on the upper part, wherein the construction is complex, the construction is slow in emergency treatment, and the water at the burst point flows out greatly, so that the treatment cannot be carried out.

Chinese patent CN203960814U "a quick device of speedily carrying out rescue work on gushing by pipe" encloses bucket, spud pile and drainage tube, encloses the bottom, middle part and the upper end of bucket inner wall and fixedly is provided with lower floor's geogrid, middle level geotechnique net and upper geotechnique net respectively, is provided with rubble geotechnique pocket between lower floor's geogrid and the middle level geotechnique net, is provided with coarse sand geotechnique pocket between middle level geotechnique net and upper geotechnique net, the diameter of rubble geotechnique pocket and coarse sand geotechnique pocket with enclose the internal diameter of bucket the same and fix on the inner wall that encloses the bucket. This structure can speedily carry out the device of speedily carrying out rescue work, and simple structure, but can't carry out effectual drainage effect, this structure probably leads to earth infiltration on every side, leads to the whole region trip silt condition of collapsing, and this structure only is applicable to the level land, can't use at ramp and right angle corner, and application range is more limited.
