Deep foundation pit underground diaphragm wall enclosure structure and chemical churning pile water stop construction method thereof
The invention relates to a deep foundation pit underground diaphragm wall enclosure structure and a chemical churning pile water stop construction method thereof. The enclosure structure comprises an underground diaphragm wall, a leakage point, a sealing steel plate and a diversion steel pipe, wherein the sealing steel plate is placed on the underground diaphragm wall surface, four corners of the sealing steel plate are fixed on the underground diaphragm wall through expansion bolts, the leakage point is aligned with the diversion steel pipe, a valve is arranged on the diversion steel pipe, and at the same time, an edge sealing material is used for edge sealing along a seam of the sealing plate and the underground diaphragm wall surface; the chemical churning pile water stop construction method of the enclosure structure comprises the steps of positioning-guide hole drilling-in position of a chemical churning pile machine-jet grouting-rotary lifting-pile forming-reinjection-single pile completion. According to the enclosure structure and the chemical churning pile water stop construction method, sealing and treatment can be performed timely when piping occurs to the diaphragm wall surface while smooth operation of a foundation pit project can be guaranteed, personal and property safety of a construction person is guaranteed, and a necessary technical support is provided for the smooth operation of the construction.
