Description

Underground engineering piping processing device and method

Technical Field

The invention relates to the technical field of underground engineering piping treatment, in particular to an underground engineering piping treatment device and a treatment method.

Background

In the process of excavation of the foundation pit, a bedding layer and rolling compaction are not carried out on the bottom of the foundation pit, so that a bottom plate does not have a good horizontal or vertical seepage-proofing structure, and the seepage pressure conduction generated by the seepage pressure difference between the water head inside the pit and the water head outside the pit can horizontally flow out along the weak silty clay or silty soil inside the pit to generate quicksand.

The generation of piping is related to uneven and discontinuous contact of the foundation soil in terms of thickness and granularity and thickness distribution, and particularly, the confined water has great difference with different stratums, flow rates and permeability in vertical rising permeation, so that fine-particle sandy soil on a contact surface can be taken away, and the contact surface is washed or earthed.

When confined water exists under the foundation pit and the foundation pit is excavated, the thickness of a waterproof layer coated on a water-bearing layer is reduced, and the water head pressure of the confined water can crack or break a foundation pit bottom plate to a certain degree, so that sudden surge, piping and seepage are caused, the foundation strength is finally damaged, and great difficulty is caused for construction. The piping and foundation pit piping can cause the base top crack, the netted or dendritic pore appears, the underground water gushes out, and soil grains and sand grains are also arranged, the foundation pit slope instability can be caused in serious cases, the surrounding buildings and the supporting structure are greatly settled and displaced, and as a result, the local part of the base is boiled, the piping water and the sand are blown out, the foundation pit water accumulation and the foundation pit soil disturbance cause great difficulty and potential safety hazards of the buildings.

The existing plugging measures are that a cofferdam is built outside a piping, loose soil is cleared at the piping, and then materials such as grains, bran, broken stones and the like are filled inside the cofferdam for plugging, so that the operation steps are complex and tedious, and the phenomenon of large-area settlement is easily caused.
