Description

Technical Field

[0001] This utility model relates to the field of inclinometer technology, specifically a device for fixing and preventing blockage of inclinometers in deep foundation pits. Background Technology

[0002] Currently, during the construction of deep foundation pit retaining structures, inclinometer tubes need to be pre-embedded before the reinforcing cage is placed in the trench to facilitate the observation of deep horizontal displacement of the retaining structure during excavation. The common installation method for inclinometer tubes is to use joints, where a new inclinometer tube is inserted into an external joint, and then the two ends are fixed with self-tapping screws. This method is continued until the designed length is reached, and the inclinometer tube is then secured to the reinforcing cage with cable ties. This installation method has several drawbacks: the inclinometer grooves are not perpendicular to the direction of the foundation pit; drilling with self-tapping screws can easily damage the tube; and there is a lack of necessary anti-clogging measures, allowing mud to easily enter through the bottom of the tube and the joints between tube sections, thus clogging the inclinometer tube. Furthermore, the inclinometer tube's internal grooves are not perpendicular to the direction of the foundation pit, leading to measurement errors and reduced monitoring accuracy. Additionally, the inclinometer tube is easily damaged during pile head removal. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a deep foundation pit inclinometer fixing and anti-blocking protection device that can improve monitoring accuracy, increase the survival rate of inclinometer tubes, has a simple structure, is easy to install, and is reusable.

[0004] This utility model is achieved through the following technical solution: a deep foundation pit inclinometer tube fixing and anti-blocking protection device, including a direction fixing mechanism, a tube bottom anti-blocking mechanism, and a tube opening protection mechanism; The direction fixing mechanism includes a left semicircular sleeve and a right semicircular sleeve. The left semicircular sleeve and the right semicircular sleeve are symmetrically distributed on the outer wall of the splicing node of two adjacent inclinometer tubes, and the left semicircular sleeve and the right semicircular sleeve are connected to each other. The anti-blocking mechanism at the bottom of the pipe includes an anti-blocking cover and an anti-blocking sleeve. The anti-blocking cover is sealed at the bottom of the inclinometer tube, and the anti-blocking sleeve is located above the anti-blocking cover and is sleeved on the outer wall of the inclinometer tube. The anti-blocking cover and the anti-blocking sleeve are connected to each other. The pipe opening protection mechanism includes a protective cover and a protective sleeve. The protective cover is sealed at the top opening of the inclinometer tube, and the protective sleeve is located below the protective cover and is fitted onto the outer wall of the inclinometer tube. The protective cover and the protective sleeve are connected to each other.

[0005] Furthermore, it also includes an anti-disturbance structure, which consists of two semi-circular shock-absorbing foams. The two shock-absorbing foams are disposed on the outer wall of the inclinometer tube and located below the tube opening protection mechanism.

[0006] Furthermore, the inner walls of the left semicircular sleeve and the right semicircular sleeve are respectively provided with limiting grooves along their length direction, and the limiting grooves are adapted to the protrusions on the outer wall surface of the inclinometer tube.

[0007] Furthermore, the anti-clogging sleeve is composed of two symmetrical semicircular tubes, which are assembled by a fixing ring fitted on their outer wall.

[0008] Furthermore, the inner walls of the left semicircular sleeve and the right semicircular sleeve are respectively provided with a first waterproof gasket.

[0009] Furthermore, the anti-clogging cover has a U-shaped cross-section, and a second waterproof gasket is provided on the inner wall of the anti-clogging cover.

[0010] Furthermore, the protective cover has a U-shaped cross-section, and a third waterproof gasket is provided on the inner wall of the protective cover.

[0011] Furthermore, the inner walls of the two shock-absorbing foams are respectively glued to the outer wall of the inclinometer tube, and the two shock-absorbing foams are fixed to the inclinometer tube by binding the outer walls of the two shock-absorbing foams with cable ties.

[0012] Furthermore: a left connecting block is provided on the outer wall of the left semicircular sleeve, and a right connecting block is provided on the outer wall of the right semicircular sleeve. The left connecting block and the right connecting block are fixed together by a first bolt.

[0013] Furthermore: an upper connecting block is provided on the outer wall of the anti-blocking sleeve, and a lower connecting block is provided on the outer wall of the anti-blocking cover; the upper connecting block and the lower connecting block are fixed together by a second bolt.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting limiting grooves that match the protrusions on the outer wall of the inclinometer tube along the length of the left and right semicircular sleeves, the left and right semicircular sleeves are installed on two adjacent inclinometer tube sections. At the same time, the protrusions on the outer wall of the inclinometer tube are locked in the limiting grooves of the left and right semicircular sleeves. Through the interaction between the protrusions and the limiting grooves, the inclinometer tube is prevented from twisting or rotating when entering the trench, ensuring that the inclinometer tube is perpendicular to the direction of the foundation pit, accurately measuring the inclinometer deformation of the foundation pit, thereby improving the monitoring accuracy.

[0015] 2. By sealing the bottom of the inclinometer tube with a tube bottom anti-blocking mechanism and sealing the tube sections with a direction fixing mechanism, mud can be effectively prevented from entering the inclinometer tube through gaps and causing blockage, thereby reducing the difficulty of monitoring and improving the accuracy of monitoring.

[0016] 3. The inclinometer pipe opening is protected by a pipe opening protection mechanism, and an anti-disturbance structure is set up to facilitate construction personnel in identifying the location of the inclinometer pipe, prevent damage to the inclinometer pipe by construction machinery during pile head breaking, and improve the survival rate of the inclinometer pipe.
