Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction, and in particular to a quick-release inclinometer tube for foundation pit monitoring. Background Technology

[0002] Currently, there exists a type of inclinometer tube for foundation pit monitoring (application number CN202320160115.1). This inclinometer tube includes a connecting pipe section and a protective cap. Both the upper and lower ends of the inclinometer tube section have circumferentially extending annular grooves with internal threads. The outer circumferential surface of the connecting pipe section has external threads, allowing the connecting pipe section to be threaded into the annular grooves. The protective cap includes a cap and a stud. The cap is located at the upper end of the inclinometer tube section, with a height greater than the depth of concrete removal. The stud is fixed to the bottom of the cap and threaded into the annular groove at the upper end of the inclinometer tube section. This inclinometer tube effectively prevents concrete debris from falling into the tube and avoids damage and deformation at the joints of the inclinometer tube sections, making jointing easier and ensuring a high survival rate for the inclinometer tube.

[0003] The main problem at present is:

[0004] 1) How to ensure the normal use of the inclinometer tube while ensuring both rapid installation and structural strength, and how to make the inclinometer grooves between the tubes consistent so that the inclinometer can slide up and down in the entire tube when in use.

[0005] In addition, there are other issues, as follows:

[0006] 2) The commonly used inclinometer tubes are sleeve connections, with an external sleeve at the connection point of the tube body. In the inclinometer monitoring of cast-in-place piles, the protruding part of the external sleeve may collide and jam with the steel cage during the installation of the tube body, thus affecting the construction speed. Summary of the Invention

[0007] The purpose of this invention is to provide a quick-release inclinometer tube for foundation pit monitoring, which allows the inclinometer to be smoothly installed into the quick-release inclinometer tube.

[0008] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0009] A quick-release inclinometer tube for foundation pit monitoring includes a tube cap, a tube bottom, and a certain number of tube body segments. Each tube body segment is provided with an inclinometer groove. The tube cap, tube body segments, and tube bottom are connected and assembled together by a quick-release mechanism. The quick-release mechanism is a snap-on groove screw-on mechanism.

[0010] Furthermore, the buckle and slot screw-on mechanism is specifically implemented as follows: buckles extending downwards are provided at the lower end of the pipe section and at the bottom surface of the pipe cap; buckle grooves are provided at the upper end of the pipe section and at the top surface of the pipe bottom; the buckle groove is composed of a narrow groove and a wide groove, the buckle is embedded in the wide groove of the buckle groove, and then rotated at a certain angle, the buckle is embedded in the narrow groove of the buckle groove, and a firm connection can be formed between the buckle and the buckle groove, thereby realizing the buckle and slot screw-on mechanism.

[0011] Furthermore, each latch slide is equipped with an anti-escape mechanism to prevent the latch from escaping from the narrow groove of the latch slide.

[0012] Furthermore, the specific structural form of the anti-escape mechanism is as follows: a threaded hole is provided at the wide groove position near the buckle slide groove on the pipe body segment, and a limit screw is provided. After the buckle enters the narrow groove of the buckle slide groove, the limit screw is screwed into the threaded hole, thereby preventing the buckle from detaching from the narrow groove of the buckle slide groove.

[0013] Furthermore, the inner wall of the tube segment is provided with a convex arc structure, and all the convex arc structures are evenly and discretely distributed on the inner wall of the tube segment. A certain space is reserved between two adjacent convex arc structures as a sliding groove for the inclinometer.

[0014] Furthermore, a handle is also provided on the top surface of the cap.

[0015] Furthermore, the bottom of the tube is configured as a downward-facing cone shape.

[0016] The main advantages of this quick-release inclinometer tube for foundation pit monitoring compared to existing technologies are as follows:

[0017] When the various pipe sections are assembled and connected together by the snap-fit ​​and slot screw-in mechanism, the convex arc structure and the inclinometer slide in each pipe section are aligned perfectly. The inclinometer slide in the entire quick-release inclinometer tube is continuous and will not be misaligned, which facilitates the smooth installation of the inclinometer in the quick-release inclinometer tube.

[0020] Figure 3This is a schematic diagram of the cap structure in the quick-release inclinometer tube for foundation pit monitoring according to this utility model. Detailed Implementation

[0021] The specific embodiments of this utility model are further described below:

[0022] This embodiment provides a quick-release inclinometer tube for foundation pit monitoring. The quick-release inclinometer tube can be quickly assembled and disassembled, thus facilitating storage and relocation.

[0023] See Figure 1 The quick-release inclinometer tube of this embodiment mainly includes a cap 6, a bottom tube 9, and a certain number of tube segments 1.

[0024] The certain number of pipe segments 1 can be connected and assembled together in sequence to form the main body of the quick-release inclinometer tube. For ease of description, this entity composed of numerous pipe segments 1 is defined as the main body.

[0025] The cap 6 is assembled at the top of the main tube body, and the bottom tube 9 is assembled at the bottom of the main tube body, thereby forming a complete quick-release inclinometer tube.

[0026] It should be noted that in the entire quick-release inclinometer tube, the "assembly connection of the cap 6 at the top of the main tube", the "assembly connection of the bottom tube 9 at the bottom of the main tube", and the "assembly connection between two adjacent tube segments 1" are all achieved through a quick-release mechanism.

[0027] Specifically, see Figure 2 Taking pipe segment 1 as an example,

[0028] Four downward-extending buckles 51 are provided at the lower end of pipe segment 1. The vertical cross-section of the buckles 51 is "L"-shaped. Four buckle grooves 52 are provided at the upper end of pipe segment 1. Each buckle groove 52 is composed of a narrow groove and a wide groove. The four buckles 51 and the four buckle grooves 52 are matched and correspond to each other. When it is necessary to connect and assemble multiple pipe segments 1, the buckle 51 of one pipe segment 1 is inserted into the wide groove of the buckle groove 52 of another pipe segment 1, and then rotated clockwise by a certain angle. The buckle 51 is then inserted into the narrow groove of the buckle groove 52, thus forming a firm connection between the buckle 51 and the buckle groove 52.

[0029] In addition, to prevent the buckle 51 from escaping from the narrow groove of the buckle slide 52, an anti-escape mechanism is provided for each buckle slide 52. Specifically, a threaded hole 53 is provided on the pipe body segment 1 near the wide groove of the buckle slide 52, and a limiting screw 54 is provided. After the buckle 51 enters the narrow groove of the buckle slide 52, the limiting screw 54 is screwed into the threaded hole 53, thereby preventing the buckle 51 from leaving the narrow groove of the buckle slide 52.

[0030] Those skilled in the art will understand that the quick-release mechanism formed by the combination of the buckle 51 and the buckle groove 52 is a prior art mechanism, and its specific structural form is common knowledge known to those skilled in the art. There is currently no unified professional name for this mechanism, and in this embodiment, it is defined as a "buckle and groove screw-on mechanism".

[0031] Next, let's take cap 6 as an example. See Figure 3 A buckle 51 is also provided on the bottom surface of the pipe cap 6. The buckle 51 of the pipe cap 6 and the buckle groove 52 of the pipe body segment 1 at the top of the main body form a quick disassembly and assembly mechanism, so that the pipe cap 6 can be quickly disassembled and assembled at the top of the main body.

[0032] Next, taking the pipe bottom 9 as an example, a snap-fit ​​groove 52 (not shown in the figure) is provided on the top surface of the pipe bottom 9. The snap-fit ​​groove 52 of the pipe bottom 9 and the snap-fit ​​51 of the pipe body segment 1 at the bottom of the main body form a quick disassembly and assembly mechanism, so that the pipe bottom 9 can be quickly disassembled and assembled at the bottom of the main body.

[0033] In addition, four convex arc structures 8 are provided on the inner wall of the tube segment 1.

[0034] As for a single convex arc structure 8, it is essentially a convex ridge on the inner wall of the pipe segment 1. The convex ridge extends along the length of the pipe segment 1, and the outline of the cross-section of the convex ridge is arc-shaped. The four convex arc structures 8 (that is, the four convex ridges) are evenly and discretely distributed on the inner wall of the pipe segment 1, with non-adjacent convex arc structures 8 facing each other.

[0035] The purpose of setting four convex arc structure parts 8 is twofold: firstly, it can strengthen the structural strength of the pipe segment 1, enabling the pipe segment 1 to have strong resistance to compression, tension, bending, and torsion; secondly, it can provide a basis for "setting the snap-fit ​​groove 52 and threaded hole 53". In fact, the snap-fit ​​groove 52 and threaded hole 53 are set at the location of the convex arc structure part 8.

[0036] A certain space is reserved between two adjacent convex arc structure parts 8 as inclinometer grooves 7, so there are four inclinometer grooves 7 in the pipe section 1. Those skilled in the art can understand that these four inclinometer grooves 7 are used to set the inclinometer, and the angle between two adjacent inclinometer grooves 7 is 90 degrees.

[0037] It should be noted that on pipe segment 1, the relative positions of the snap-fit ​​and slot screw-on mechanism (i.e., snap-fit ​​51, snap-fit ​​slot 52, and threaded hole 53) with the convex arc structure 8 and the inclinometer slot 7 are fixed. This ensures that when the various pipe segments 1 are assembled together via the snap-fit ​​and slot screw-on mechanism, the convex arc structure 8 and the inclinometer slot 7 in each segment 1 are perfectly aligned. The inclinometer slot 7 in the entire quick-release inclinometer tube is continuous and will not misalign, thus facilitating the smooth installation of the inclinometer into the quick-release inclinometer tube. This is a significant innovation of this embodiment.

[0038] In addition, it should be noted that

[0039] The top surface of the cap 6 is also provided with a handle 61, which facilitates the rotation of the cap 6;

[0040] The bottom of the tube 9 is configured as a downward-facing cone. In soil inclinometer surveying, since a large amount of water accumulates in the hole after drilling, the bottom of the cone can be weighted to reduce buoyancy.

[0041] The method of using the quick-release inclinometer tube in this embodiment is as follows:

[0042] As needed, prepare a certain number of pipe segments 1, connect all pipe segments 1 together through a quick disassembly and assembly mechanism to form the main body of the quick-release inclinometer tube, install the inclinometer into the main body, then assemble the pipe cap 6 at the top of the main body and the pipe bottom 9 at the bottom of the main body, thereby assembling a complete quick-release inclinometer tube.

[0043] It should be noted that the automatic inclinometer can be directly installed into the main pipe, while the inclinometer probe of the manual inclinometer is used to complete the measurement by opening the pipe cap and sliding up and down along the groove in the pipe.

[0044] The main advantages of the quick-release inclinometer tube of this embodiment are:

[0045] 1) When the various pipe sections 1 are assembled and connected together by the snap-fit ​​and slot screw-in mechanism, the convex arc structure 8 and the inclinometer slide 7 in each pipe section 1 are aligned perfectly. The inclinometer slide 7 in the entire quick-release inclinometer tube is continuous and will not be misaligned, which is conducive to the smooth installation of the inclinometer in the quick-release inclinometer tube.

[0046] In addition, the quick-release inclinometer tube of this embodiment has other advantages, as follows:

[0047] 2) The quick-release inclinometer tube of this embodiment can achieve splicing without the need for an external sleeve, thereby enabling the rapid installation of the tube body. The tube body will not get stuck due to the collision between the protruding part of the external sleeve and the steel cage, thus ensuring the construction speed.

[0048] 3) The convex arc structure 8 provided on the inner wall of the pipe section 1 can enhance the structural strength of the pipe section 1, so that the pipe section 1 can have strong resistance to compression, tension, bending and torsion.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
