Description

TECHNICAL FIELD

[0001] The utility model relates to surveying and mapping monitoring field especially a surveying and mapping pipe anti silt joint. BACKGROUND

[0002] With the rapid development of China's economy, city construction has also entered a stage of rapid development, and more and more high-rise buildings, subway engineering, municipal roads and bridges, comprehensive pipe gallery and so on, and city underground engineering has entered a stage of vigorous development. With more and more city buildings and facilities, the environmental safety requirement is higher and higher. The five characteristics of current foundation pit engineering are deep, large, near, tight and difficult, and the safety monitoring requirement is higher and higher.

[0003] Foundation pit engineering monitoring is an indispensable part of underground engineering construction. Combined with geotechnical engineering analysis means and engineering experience, monitoring data has the functions of reflecting engineering safety state and inverting and predicting construction risk. Therefore, monitoring data can be called the "thermometer" of the project and the "eyes" of safe construction, and is the most important information means for judging structure stability, surrounding environment safety, optimizing design and guiding safe construction of foundation pit engineering.

[0004] In the monitoring project of soil foundation pit engineering, deep horizontal displacement is a must-measure item in safety level one and two foundation pits, and is a suitable-measure item in safety level three foundation pits. Generally, the deep horizontal displacement of the soil body is suitable to be arranged in the middle, the sun angle and the representative part of the foundation pit periphery. When observing the deep horizontal displacement by using the inclinometer, the inclinometer tube needs to be buried in the soil body. The commonly used inclinometer tube is generally made of PVC, ABS and aluminum alloy materials. In order to facilitate transportation and construction, the tube length is usually 2 meters, the joint part is made of the same material with a length of about 0.2m, and is connected according to the design length when buried in the soil. In actual use, because of the sealing problem of the joint part, soil particles often enter the inclinometer tube. The particles of silt are too small to enter the tube along the joint gap of the inclinometer tube under water pressure when meeting water. Long-term such a phenomenon will cause the bottom of the inclinometer tube to be filled with soil, the inclinometer tube is abandoned, and the monitoring data is lost.

[0005] The applicant finds that the traditional inclinometer tube joint has the following problems in the measurement work: poor sealing, and soil particles easily enter the inclinometer tube to cause the hole to be scrapped.

[0006] Therefore, the application provides an inclinometer tube anti-silt joint. CONTENT OF THE UTILITY MODEL

[0010] By using the above technical scheme, when measuring and monitoring, the inclinometer pipe is connected tightly, the connection is not easy to loosen, and various types of soil particles are not easy to enter.

[0011] Further, the external sleeve is 5mm thick, 70mm in inner diameter and 300mm long, and is made of ABS material.
