A kind of early warning system and working method of underground structure floating based on automatic pumping and drainage of water collection well

Abstract

The invention discloses an underground structure floating early warning system based on automatic pumping and drainage of a water collection well and a working method thereof. The system includes a radar water level monitor, a data processing module, an automatic pumping and drainage module, a threshold analysis module, and a control and early warning device. The present invention monitors the water level value in the water collection well through the radar water level monitor to further control the pumping and drainage of the induction pump to achieve the purpose of automatic groundwater pumping and drainage, and realize the energy saving of the underground engineering dewatering system such as foundation pit excavation; at the same time, the water level in the water collection well is dynamic The situation indirectly represents the amount of groundwater at the construction site and its real-time dynamics. The floating early warning module can be used to judge whether the underground structure is floating or not, and complete the information processing process of the effect of groundwater on the underground structure; use the control and early warning device to realize the priority of the pumping and drainage control of the water collection well And the visualization of the early warning of the flotation of the underground structure facilitates the relevant personnel to realize the early warning of the engineering precipitation and the flotation accident of the underground structure through simple operation.

Description

technical field [0001] The invention belongs to the field of early warning of underground water disasters in underground engineering, and in particular relates to an early warning system for floating underground structures based on automatic pumping and drainage of water collection wells and a working method thereof. Background technique [0002] Under the background of the rapid development of national infrastructure construction, the number of projects involving underground space is increasing, so it also presents the characteristics of wide geographical distribution and diversified geological and engineering environments, which brings great challenges to the construction of the underground part of the project. In projects near seas and lakes, construction in rainy seasons, and complex geological conditions, the problems of poor drainage of foundation pits and floating underground structures occur frequently, resulting in greater engineering risks and economic losses.

AI Technical Summary

Problems solved by technology

The disadvantages of this invention are: 1) only use permeable bricks and water outlets as anti-floating facilities in the basement, if the groundwater level increases sharply in the rainy season, it will not be able to achieve higher drainage efficiency; 2) the technical solution is only a drainage method for the basement, Does not involve anti-floating related issues

The shortcoming of this utility model is: 1) the control water level of this collection well is a constant value of 50cm from the top surface of the well and 50cm from the bottom of the well. 2) This method only realizes the automatic pumping and drainage of underground works, and cannot make timely and reasonable predictions and early warnings for the uplift of underground structures

[0006] To sum up, the existing technologies for treating groundwater during construction mostly focus on new pumping and drainage devices and the automation of pumping and drainage. An efficient and reliable intelligent integrated system that can realize groundwater level monitoring, automatic pumping and drainage, and early warning of floating accidents
