Burying method of inclination measuring pipes in soil body

Abstract

The invention discloses a burying method of an inclination measuring pipes in a soil body. The burying method comprises the following steps that (a) holes are drilled; (b) slurry is continuously filled in drilled holes for hole washing after the hole drilling completion; and (c) after the hole washing completion, a prepared inclination measuring pipe is inserted into the drilled hole, the bottom end of the inclination measuring pipe with an end cover is firstly downwards placed into the drilled hole, clean water is fully filled in the inclination measuring pipe, the upper section of inclination measuring pipe is connected, the insertion is continuously carried out after the connection completion, the operation is repeated in such a way until the inclination measuring pipe is inserted into the hole bottom, the rest inclination measuring pipe is cut off, the distance from a pipe opening of the inclination measuring pipe to the ground is 200 to 500mm, the pipe opening of the inclination measuring pipe is sealed and covered by a top cover, and the gap of the drilled holes outside the inclination measuring pipe is filled by sand or bentonite. The burying method has the advantages that the inclination measuring pipe burying is convenient, the construction speed is high, the cost is low, the inclination measuring pipe and the surrounding soil body can be enabled to form a whole after the burying, the inclination measuring pipe can deform along with the horizontal displacement of the soil body, and the horizontal displacement of the soil body at the position is analyzed and obtained through measuring the horizontal deformation of different positions of the inclination measuring pipe.

Description

technical field [0001] The invention relates to an inclinometer pipe, in particular to a method for embedding an inclinometer pipe used for foundation pit safety monitoring or slope body monitoring. Background technique [0002] With the development of urban construction, high-rise super high-rise buildings, subways, etc. are involved in the construction of foundation pits. In order to ensure the safe and smooth construction of foundation pits, deformation monitoring of foundation pits is an indispensable work in foundation pit construction. In the foundation pit deformation monitoring, measuring the horizontal displacement of the soil around the foundation pit is an important content to judge the safety of the foundation pit. During the excavation of the foundation pit soil, the enclosure structure (enclosure piles, underground diaphragm walls, etc.) is excavated along with the soil, which breaks the balance of forces inside and outside the enclosure structure, and the encl...

Problems solved by technology

[0003] After the inclinometer pipe is buried by the conventional method, there is a gap between the inclinometer pipe and the soil, and the data measured by the inclinometer pipe cannot accurately reflect the horizontal displacement of the soil; the embedding operation of the inclinometer pipe is complicated and the construction speed is slow; Covered or crushed by vehicles, damaged, causing difficulties for inclinometer work, serious inclination measurement cannot be carried out, resulting in the loss of inclinometer data
