Building foundation ditch or side slope deformation monitoring method and building foundation ditch or side slope deformation monitoring reflection device

Abstract

The invention discloses a building foundation ditch or side slope deformation monitoring method and a building foundation ditch or side slope deformation monitoring reflection device. According to the building foundation ditch or side slope deformation monitoring method and the building foundation ditch or side slope deformation monitoring reflection device, when a total station instrument is used for monitoring building foundation ditch or side slope deformation, bolts or reinforcing steel bars are buried in advance at the position of each monitoring point of a monitored side slope or a monitored building foundation ditch, then the monitoring reflection device with aluminum-foil paper, sliver paper or a thin aluminum plate as the reflection face is fixed on each bolt or each reinforcing steel bar, a cross-curve-shaped reflection center is manufactured in each aluminum-foil paper or each thin aluminum plate serving as the reflection face, and then the total station instrument is used for reading data of the cross-curve-shaped reflection centers on the reflection faces of the monitoring reflection devices, so that the building foundation ditch side slope deformation or the foundation ditch deformation can be monitored through the total station instrument. The device has the advantages of being safe and reliable in use, convenient to use, simple in structure, easy to manufacture, low in manufacturing cost and use cost, high in monitoring accuracy and working efficiency and the like, and can be used in monitoring programs of the deformation on the side slope, a building and the like.

Description

technical field [0001] The invention relates to a monitoring method and a monitoring reflection device for building foundation pit or slope deformation, belonging to the technical field of building foundation pit deformation monitoring. Background technique [0002] At present, when monitoring the deformation of building foundation pits or slopes in the prior art, the conventional monitoring procedure is to first fix the measuring nails on the slope body or the concrete beam of the slope support system, and then In each monitoring, the centering rod is manually erected at the cross point on the top of the measuring nail, and the centering rod is centered. When the measurement bubble of the centering rod is in the center, the centering rod is read by the total station. The data of the center point of the top prism, so as to achieve the purpose of monitoring. In the prior art, the method of monitoring building foundation pit or slope deformation by using a total station throu...

AI Technical Summary

Problems solved by technology

[0003] 1. Since manual operation is required for each measurement point, the measurement progress is slow, and due to human reasons, there are human errors in the measurement point data;

[0004] 2. At present, the safety level of most urban foundation pits is level 1, and the depth of foundation pits is generally greater than 10m, and some even reach more than 30 meters. The location of monitoring points is generally located on the edge of the slope and foundation pit, and manual climbing is required for each measurement. Climbing, increasing the danger to climbers;

[0005] 3. Since the structures of measuring nails, centering rods and prisms are relatively complicated, the production costs are relatively high, so the cost of monitoring is relatively high

[0006] Due to the above-mentioned shortcomings in the existing monitoring methods for the deformation of building foundation pits, they still cannot meet the needs of use.
