Description

Technical Field

[0001] This utility model belongs to the field of support technology and relates to a trench support structure, particularly a trench support structure for municipal pipeline engineering. Background Technology

[0002] Currently, shallow-buried municipal pipelines are mainly constructed through open-cut excavation. However, due to limitations in construction space, geological conditions, and traffic demands, pipelines in municipal roads and residential areas generally cannot be excavated with large slopes. To ensure the safety of the construction process, it is often necessary to support the excavated trenches. Trench support refers to temporary or permanent support measures taken during pipeline trench excavation to prevent trench wall collapse, ensure construction safety, and reduce the impact on the surrounding environment and underground pipelines.

[0003] A trench support structure for municipal pipeline engineering, published in Chinese Patent Publication No. CN223317201U, includes: at least four columns, each located at one of the four corners of a rectangle; a retaining mechanism arranged along the longitudinal side of the rectangle; and a support mechanism arranged along the transverse side of the rectangle. The support mechanism includes a telescopic member, with positioning holes at both ends of the telescopic member. A fixing pin is inserted into each positioning hole. A first sliding groove is provided on the side wall of each column, and multiple pin holes are spaced vertically along the side wall of the first sliding groove. The fixing pin is inserted into each pin hole. This support structure allows for adjustment of the support width through the telescopic member, increasing the applicability of the support structure, improving construction quality, and reducing construction errors. Furthermore, the telescopic member is connected to the column via fixing pins, making disassembly and installation very convenient.

[0004] By adopting a combination of telescopic components and fixed pins, it improves upon the traditional horizontal bracing support. Although it is easy to disassemble or install, the support rods (i.e., its telescopic components) of the horizontal bracing support affect the working space of machinery in the trench, and the problem of inconvenience for personnel is not solved. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a trench support structure for municipal pipeline engineering. The technical problem this utility model aims to solve is: how to achieve a structure that does not affect the working space of machinery within the trench and facilitates personnel work.

[0006] The objective of this utility model can be achieved through the following technical solutions: A trench support structure for municipal pipeline engineering includes two sets of fixing plates and retaining plates. The fixing plates have a fixing hole on one side of their top end, and the retaining plates slide inside the fixing plates through the fixing hole. A first insert plate is fixed at the bottom end of the retaining plates, and a second insert plate is fixed at the other side of the bottom end of the fixing plates.

[0007] The working principle of this utility model is as follows: A second insert plate is inserted above the trench along the outer surface of the trench, so that the fixing hole is located inside the trench, close to the inner wall. Then, a retaining plate is placed inside the trench along the fixing hole, so that one side of the retaining plate is in contact with the inner wall of the trench. Finally, the retaining plate is pushed to drive the first insert plate into the inner surface of the inner wall, completing the support. This trench support structure for municipal pipeline engineering uses a fixing plate, a second insert plate, and a first insert plate instead of a crossbar to fix the position of the retaining plate, which does not affect the working space of machinery inside the trench and facilitates personnel work.

[0008] Multiple expansion bolt cylinders slide inside the retaining plate, and multiple limiting blocks are fixed on the outer cylindrical surface of the expansion bolt cylinders. Multiple limiting holes are opened inside the retaining plate, and the limiting blocks slide and engage inside the limiting holes.

[0009] Using the above structure, the movable expansion bolt cylinder is inserted into the inner wall of the trench along the inside of the retaining plate, while simultaneously driving the limiting block to be inserted into the limiting hole. Then, the soil inside the expansion bolt cylinder is removed, and finally, the expansion bolt is inserted along the expansion bolt cylinder to complete the fixation. This further increases the fixation stability of the retaining plate and evenly distributes the pressure on both ends of the retaining plate, thereby preventing the retaining plate from deforming.

[0010] An extension hole is provided on the other side of the top of the fixing plate, and the extension hole extends through and into the interior of the second insert plate. A pressing plate slides inside the extension hole. Stabilizing holes are provided on both sides of the second insert plate, and stabilizing plates slide inside the stabilizing holes.

[0011] With the above structure, the extrusion plate is inserted along the inside of the extension hole, so that the extrusion plate squeezes the stabilizing plate and moves it forward along the stabilizing hole into the ground, thereby increasing the connection stability of the second insert plate with the ground and further increasing the support stability of the retaining plate.

[0012] One end of the stabilizing plate is fixed with an arc-shaped elastic plate, and both ends of the arc-shaped elastic plate are fixed to the corresponding positions on the inner wall of the second insert plate.

[0013] The above structure facilitates the rebound of the stabilizing plate, making it easier to remove the second insert plate later.

[0014] The top of the extrusion plate is fixed with a pull plate, and the bottom of the extrusion plate has two inclined surfaces symmetrically opened about its vertical center line.

[0015] The above structure facilitates the deformation of the arc-shaped elastic plate by the extrusion plate.

[0016] Compared with existing technologies, the trench support structure of this municipal pipeline project has the following advantages: This utility model uses a fixed plate, a second insert plate, and a first insert plate to replace the crossbar to fix the position of the retaining plate, which will not affect the working space of the machinery in the trench and facilitates the work of personnel.

[0017] This utility model involves moving the expansion bolt cylinder along the inside of the retaining plate and inserting it into the inner wall of the trench, while simultaneously driving the limiting block into the limiting hole. Then, the soil inside the expansion bolt cylinder is removed, and finally, the expansion bolt is inserted along the expansion bolt cylinder to complete the fixation. This further increases the fixation stability of the retaining plate and evenly distributes the pressure on both ends of the retaining plate, thereby preventing deformation of the retaining plate.

[0018] In this invention, a pressing plate is inserted along the inside of the extension hole, causing the pressing plate to press the stabilizing plate forward along the stabilizing hole until it is inserted into the ground, thereby increasing the connection stability between the second insert plate and the ground, and further increasing the support stability of the retaining plate.

Detailed Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1-5As shown, the trench support structure of this municipal pipeline project includes two sets of fixing plates 201 and retaining plates 101. The top side of the fixing plate 201 has a fixing hole 202. The retaining plate 101 slides inside the fixing plate 201 through the fixing hole 202. The bottom end of the retaining plate 101 is fixed with a first insert plate 102, and the other side of the bottom end of the fixing plate 201 is fixed with a second insert plate 204.

[0027] Above the trench, a second insert plate 204 is inserted along the ground outside the trench, so that the fixing hole 202 is located inside the trench and close to the inner wall of the trench. Then, the retaining plate 101 is placed inside the trench along the fixing hole 202, so that one side of the retaining plate 101 is in contact with the inner wall of the trench. Finally, the retaining plate 101 is pushed to drive the first insert plate 102 to be inserted into the ground inside the inner wall, thus completing the support. The trench support structure of this municipal pipeline project uses the fixing plate 201, the second insert plate 204 and the first insert plate 102 to fix the position of the retaining plate 101 instead of the crossbar, which will not affect the working space of the machinery in the trench and facilitates personnel work.

[0028] Multiple expansion bolt cylinders 103 slide inside the retaining plate 101. Multiple limiting blocks 104 are fixed on the outer column surface of the expansion bolt cylinders 103. Multiple limiting holes 105 are opened inside the retaining plate 101. The limiting blocks 104 slide and engage inside the limiting holes 105.

[0029] In this embodiment, the movable expansion bolt cylinder 103 is inserted into the inner wall of the trench along the inside of the retaining plate 101, while simultaneously driving the limiting block 104 to be inserted into the limiting hole 105. Then, the soil inside the expansion bolt cylinder 103 is removed, and finally, the expansion bolt is inserted along the expansion bolt cylinder 103 to complete the fixation. This further increases the fixation stability of the retaining plate 101 and evenly distributes the pressure on both ends of the retaining plate 101, thereby preventing the retaining plate 101 from deforming.

[0030] An extension hole 206 is provided on the other side of the top of the fixing plate 201, and the extension hole 206 extends through and into the interior of the second insertion plate 204. A pressing plate 203 slides inside the extension hole 206. A stabilizing hole 205 is provided on both sides of the second insertion plate 204, and a stabilizing plate 208 slides inside the stabilizing hole 205.

[0031] In this embodiment, a pressing plate 203 is inserted along the inside of the extension hole 206, so that the pressing plate 203 presses the stabilizing plate 208 forward along the stabilizing hole 205 and inserts it into the ground, thereby increasing the connection stability of the second insert plate 204 with the ground and further increasing the support stability of the retaining plate 101.

[0032] An arc-shaped elastic plate 207 is fixed at one end of the stabilizing plate 208, and both ends of the arc-shaped elastic plate 207 are fixed to the corresponding positions on the inner wall of the second insert plate 204.

[0033] In this embodiment, the stabilizing plate 208 is made easier to spring back and reset, making it easier to pull out the second insert plate 204 later.

[0034] A pull plate is fixed at the top of the extrusion plate 203, and two inclined surfaces are symmetrically opened at the bottom of the extrusion plate 203 about its vertical center line.

[0035] In this embodiment, the extrusion plate 203 facilitates the deformation of the arc-shaped elastic plate 207.

[0036] The working principle of this utility model: When installing the support structure in the trench, firstly, insert the second insert plate 204 along the ground outside the trench, so that the fixing hole 202 is located inside the trench and close to the inner wall of the trench. Then, place the retaining plate 101 inside the trench along the fixing hole 202, so that one side of the retaining plate 101 is in contact with the inner wall of the trench. Finally, push the retaining plate 101 to drive the first insert plate 102 to insert into the ground inside the inner wall. Move the expansion bolt cylinder 103 along the inside of the retaining plate 101 to insert into the inner wall of the trench, while driving the limiting block 104 to insert into the limiting hole 105. Then, remove the soil inside the expansion bolt cylinder 103, and then insert the expansion bolt along the expansion bolt cylinder 103 to complete the fixation. Finally, insert the compression plate 203 along the extension hole 206, so that the compression plate 203 compresses the arc elastic plate 207 to deform. The deformation of the arc elastic plate 207 pushes the stabilizing plate 208 forward along the stabilizing hole 205 to be inserted into the ground, thereby completing the support fixation.

[0037] In summary, by using the fixing plate 201, the second insert plate 204, and the first insert plate 102 to replace the crossbar in fixing the position of the retaining plate 101, the working space of the machinery in the trench will not be affected, and it is convenient for personnel to work.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
