Inclinometry pipe installation structure and installation method
The invention discloses an inclinometry pipe installation structure and installation method and relates to the technical field of displacement monitoring of soil around a foundation pit. By means of the inclinometry pipe installation structure and installation method, the technical problem that the compactness of an interval between the outer wall of an inclinometry pipe and the inner wall of an inclinometry hole cannot be maintained is solved. The inclinometry pipe installation structure and installation method are characterized in that the interval between the outer wall of the inclinometrypipe and the inner wall of the inclinometry hole is provided with a mud slurry layer internally containing bentonite and portland cement, the mud slurry layer is tubular, the outer wall of the mud slurry layer is fixedly connected with the inner wall of the inclinometry hole, and the inner wall of the mud slurry layer is fixedly connected with the outer wall of the inclinometry pipe. When actual installation is performed, by means of the mud slurry layer composed of the portland cement and the bentonite, on the one hand, because of physical properties of the portland cement, the hardening timeof the portland cement is shortened; on the other hand, because of the physical properties of the bentonite, the bentonite can effectively fill pores in the mud slurry layer after expansion by meeting water, so that the hardening efficiency is made to be higher and the compactness degree is made to be higher after mud slurry pouring is completed, and the interval between the inclinometry pipe andthe inclinometry hole is finally made to be filled more compactly.
本发明公开了一种测斜管安装结构及安装方法，涉及基坑周围土体位移监测技术领域，旨在解决难以保持测斜管外壁与测斜孔内壁间隙处的密实的技术问题，其技术方案要点是测斜管外壁与测斜孔内壁间隙处设有内含膨润土及硅酸盐水泥的泥浆层，泥浆层呈管状，泥浆层外壁与测斜孔内壁固定连接，泥浆层内壁与测斜管外壁固定连接。实际安装时，由硅酸盐水泥与膨润土组成的泥浆层，一方面由于硅酸盐水泥的物理性质，其硬化时间缩短，另一方面，由于膨润土的物理性质，其遇水膨胀后可有效填充泥浆层内的孔隙，从而可使得泥浆浇筑完成后，硬化效率更高，且密实程度更高。从而最终使得测斜管与测斜孔的间隙处填充的更为密实。
