Underground parking well structure with vibrating wire type sensors and one-way radio frequency chip

Abstract

The invention discloses an underground parking well structure with vibrating wire type sensors and a one-way radio frequency chip. The underground parking well structure is the same as an existing soft soil area foundation pit technology, cement-mixed piles are used as water stop curtains, cast-in-situ bored piles are used as supporting piles, and reinforced concrete inner walls are arranged on the inner sides of the supporting piles. The underground parking well structure is characterized in that the vibrating wire type sensors for testing out-of-pit soil body lateral stress are welded to main ribs of the supporting piles, and the vibrating wire type sensors are connected to a data acquisition processor outside a well through wires and connected with a communication module through wires;launching is performed after signals enter the communication module provided with the one-way radio frequency chip, detection system software is downloaded at a remote receiving server, on a computerscreen, an out-of-pit soil body stress change curve can be checked, and pre-warning is performed when the peak exceeds the software setting indicator. Compared with the prior art, the underground parking well structure can monitor the soil body stress change of the outer side of a civil engineering structure by wireless propagation in real time by multiple people, and once the stress exceeds the warning data, timely early warning is made to avoid a collapse accident.

Description

technical field [0001] The invention relates to the construction field, in particular to an underground parking well structure with a vibrating wire sensor and a one-way radio frequency chip. Background technique [0002] As we all know, since my country's reform and opening up, there have been many accidents in construction foundation pit projects in various places, mainly because the pit walls collapsed and endangered surrounding roads or buildings. Sometimes a single foundation pit project will cause tens of millions of yuan in major losses. The reason is that the change of soil pressure outside the pit is not monitored dynamically in real time. A heavy rainstorm caused the groundwater level to rise, and the mechanical properties of the soil outside the pit changed. Reinforcement measures were not taken in time until the pit wall collapsed. Contents of the invention [0003] The invention provides an underground parking well structure with a vibrating wire sensor and ...
