Description

Rear-mounted implantable recyclable inclinometer tube

Technical Field

The invention belongs to the technical field of side slope soil displacement monitoring, and particularly relates to a rear-mounted implantable recyclable inclinometer.

Background

The inclination measurement technology is a common engineering technical means for detecting the displacement and inclination of an engineering pile and a supporting structure in engineering construction. The technical means needs to lay a stable inclinometer and use an inclinometer for testing. By the technical means, engineering technicians can obtain accurate data of the inclination and displacement of the structure body, judge the verticality and the change value of the structure body in the using process and provide early warning for safe construction.

At present, two methods are provided for the layout of the inclinometer. For supporting structures such as cast-in-place slabs, piles and walls, the inclinometer pipes need to be fixed on the reinforcement cage before the reinforcement cage is placed down, and the inclinometer pipes and the reinforcement cage are poured into the supporting structures together when concrete is poured, so that the method is called a preset pouring method. For soil and rock slopes, a drilling machine is used for excavating deep holes, and a measuring pipe is lowered down and then gaps are backfilled by bentonite, so that the method is called a post-implantation method.

Aiming at the postposition implantation type inclinometer, the following problems exist in the actual use process of the engineering:

(1) the inner wall of the inclinometer pipe is provided with 4U-shaped clamping grooves which are mutually 90 degrees, and the two opposite clamping grooves can be used for the inclinometer to slide up and down. After the inclinometer pipe is embedded, one pair of the 2 pairs of clamping grooves needs to be ensured to be perpendicular to the other pair of the clamping grooves, and the angle requirement is difficult to ensure due to the fact that backfilling and crack pouring are needed during actual construction.

(2) When a drilling machine is used for pore forming, water can be gathered in a certain depth range of the bottom of the hole due to the need of using a slurry retaining wall and underground water. The existing inclinometer pipe used in engineering is a closed structure, and is difficult to sink to a preset depth due to the buoyancy effect.

(3) The inclinometer pipe belongs to disposable investment consumables and cannot be reused.

(4) Because the aperture is greater than the deviational survey pipe external diameter, the straightness that hangs down is difficult to guarantee after the deviational survey pipe sinks.

(5) The accident that the inclinometer probe is blocked inside the inclinometer or falls to the bottom of the inclinometer and cannot be taken out frequently occurs, the construction cost of the inclinometer probe is high, and the accident not only causes scrapping of the inclinometer but also causes great economic loss.

(6) After the inclinometer pipe sinks to a preset depth, the bentonite is used for filling joints, so that the upper part is easy to fill, and the middle part and the lower part are difficult to fill or even to be hollow.
