Abstract

The invention relates to a blind ditch siphon drainage system for a foundation pit. A basement outer wall is arranged in the stepped deep foundation pit, drainage blind ditches are arranged on the periphery of the outer side of the basement outer wall, the drainage blind ditches are connected and fully distributed along the position close to the foundation pit wall from the high bottom plate surface to the low bottom plate surface of the stepped foundation pit , the drainage blind ditch at the low bottom plate surface is communicated to a water collection pit, a self-suction pump is placed inthe water collection pit, and the self-suction pump draws water directly into a reservoir on the low ground. The blind ditch siphon drainage system is applicable to a mountain foundation pit with large excavation depth, high underground water level and complicated basement design and a foundation pit with a certain height difference or obvious high-low span.

Description

technical field [0001] The invention relates to a siphon drainage system for a foundation pit blind ditch, in particular to a multi-step ultra-deep foundation pit depressurization drainage. Background technique [0002] How to effectively satisfy the drainage of foundation pits is a problem that has to be considered under the current mountainous conditions in our country. However, the traditional base drainage method cannot achieve the economical and effective drainage effect of the construction site. In order to solve this problem, we have researched and used a construction measure for pressure reduction and drainage of ultra-deep foundation pits, which combines the idea of ​​"combination of reduction and drainage" to meet the depth of groundwater level and the formation of stepped high and low spans during the excavation of foundation pits. The new drainage measures for foundation pits can achieve the purpose of economical and effective drainage. Contents of the inventi...
