Embodiment
[0034] A foundation pit displacement automatic monitoring system, such as figure 1 As shown, it includes a number of signal receivers 2 arranged in an array on the top of the side of the foundation pit 1. The signal receivers 2 have corresponding numbers. There is a support column 41, and a support seat 4 is arranged on the support column 41. The support seat 4 is parallel to one side of the foundation pit 1. The signal transmitter 3 that moves along the length direction of the support seat 4 is provided with a drive Its driving mechanism 5 slides along the length direction of the support base 4 , the signal receiver 2 and the signal transmitter 3 are respectively connected with control terminals. The driving mechanism 5 drives the signal transmitter 3 to slide along the support base 4 at regular intervals, and sends signals to each signal receiver 2, and the control terminal analyzes the time difference between the signal sent by the signal transmitter 3 and the signal receiv...

The invention relates to the field of foundation pits, and aims to solve the problem that the displacement of the foundation pits cannot be detected in time, and particularly relates to an automatic foundation pit displacement monitoring system. The automatic foundation pit displacement monitoring system comprises a plurality of signal receivers arranged at the top of a side edge of a foundation pit in an array, a supporting column is arranged at the central position of the bottom of the foundation pit, a supporting column is arranged at the central position of the bottom of the foundation pit, a supporting seat is arranged on the supporting column, the supporting seat is parallel to the side edge of one side of the foundation pit, a signal transmitter moving along the length direction ofthe supporting seat is arranged on the supporting seat, the signal transmitter is provided with a driving mechanism for driving the signal transmitter to slide along the length direction of the supporting seat, and the signal receivers and the signal transmitter are respectively connected with control ends. The driving mechanism drives the signal transmitter to periodically along the supporting seat and to send signals to the signal receivers, the distance between the signal transmitter and the signal receiver can be obtained according to a time difference of received signals and a signal propagation speed, and the position of the vertical direction of the top of the foundation pit can be obtained through the change of the distance.
Description
technical field [0001] The invention relates to the field of foundation pits, more specifically, it relates to an automatic monitoring system for foundation pit displacement. Background technique [0002] Foundation pit collapse is the most common safety accident in the process of engineering construction. The accident is often accompanied by heavy casualties and economic losses, causing adverse social impacts; When the displacement of the pit support structure exceeds the warning value, measures shall be taken to reinforce it. [0003] However, the method of entrusting a third party to conduct regular monitoring alone has certain defects and deficiencies: first, the monitoring is not continuous, and the collapse accident may occur within the time period between two adjacent regular monitoring intervals; secondly, the regular monitoring report is sent to The time to arrive at the construction site is often delayed, and the precious best time for emergency rescue will be los...
