Description

Technical Field

[0001] This utility model belongs to the field of pipeline trench support technology, specifically relating to a support component of a pipeline trench support system. Background Technology

[0002] In municipal engineering projects, the trenches and foundation pits for pipelines (pipe galleries) are often shallow (less than 5 meters) with long routes, resulting in a large amount of work and high costs for foundation pit support.

[0003] Traditional support structures typically employ a system of Larssen sheet piles combined with steel walers and steel supports to ensure the safety of the foundation pit during pipeline construction. Larssen sheet piles require mechanical installation, one pile at a time, and pre-drilling is necessary when encountering hard plastic soil layers. The steel walers and supports, on the other hand, require manual welding installation.

[0004] In actual engineering cases, due to various factors, the welding quality between the steel supports and the steel walers is poor, and the connection between the steel supports and the steel walers is not tight enough. At the same time, traditional steel supports cannot be prestressed and cannot actively resist stress, resulting in the steel supports failing to effectively limit earth pressure and the deformation of the support piles. Especially when the soil conditions on the sidewalls of the foundation pit are poor, it can lead to problems such as large foundation heave, soft soil squeezing out from between the support piles, and even induce engineering accidents such as deformation of the surrounding environment, excessive settlement, and foundation pit collapse, posing a high safety risk. Utility Model Content

The movable plate is fixed to the first connecting member. The fixed plate is fixed to the first end of the telescopic member. The second end of the telescopic member is fixed to the second connecting member. The moving direction of the movable end of the jack is parallel to the telescopic direction of the telescopic member.

[0008] The first connector is used to be bolted to one side of the column, and the second connector is used to be bolted to the other side of the column.

[0033] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0034] This embodiment provides a support component for a pipeline trench support system, including a first connector 1, a movable end 2, an expansion joint 3, and a second connector 4.

[0035] The movable end 2 includes a fixed plate 201, a movable plate 202, and a jack 203. The jack 203 is mounted on the fixed plate 201. The movable end of the jack 203 is fixed to the movable plate 202. The movable plate 202 is fixed to the first connecting member 1. The fixed plate 201 is fixed to the first end of the telescopic member 3. The second end of the telescopic member 3 is fixed to the second connecting member 4. The moving direction of the movable end of the jack 203 is parallel to the telescopic direction of the telescopic member 3.

[0036] For example, see Figure 1 The movable plate 202 and the fixed plate 201 are arranged in parallel at intervals, with the jack 203 located between them. The base of the jack 203 is fixed to the fixed plate 201, and the moving end of the jack 203 can move left and right. Simultaneously, the moving end of the jack 203 is fixed to the movable plate 202, meaning the movable plate 202 can move left and right. Next, the first connecting piece 1 is fixed to the movable plate 202, meaning the first connecting piece 1 can move left and right. The fixed plate 201 is fixed to the left end of the telescopic member 3, and the right end of the telescopic member 3 is fixed to the second connecting piece 4. The telescopic member 3 can extend and retract in the left and right directions, thereby adjusting the length of the supporting component. The telescopic member 3 also has a built-in locking function. After adjusting the telescopic member 3 to the appropriate length and locking it, the length of the supporting component can still be finely adjusted using the jack 203, allowing for more precise adjustment and the application of prestress to the column.

[0037] The first connector 1 is used to connect to one side column by bolts, and the second connector 4 is used to connect to the other side column by bolts.

[0038] For example, see Figure 2 The first connector 1 may have two screw holes, and a connecting plate with two screw holes is provided on the side wall of the column. The two screw holes of the first connector 1 are aligned with the two screw holes of the connecting plate, and then bolts are passed through the aligned screw holes and tightened with nuts to connect the first connector 1 to the column. Similarly, the second connector 4 can also be connected in the same way.

[0039] Based on the above structure, the support member provided in this embodiment can adjust the length of the support member through the telescopic member 3 so that the support member meets the support requirements. Then, it can be moved by the moving end of the jack 203, thereby applying prestress to the column, so that the support member can tighten the column, effectively solving the problem that the steel support in the trench soft soil foundation pit cannot actively bear the force, resulting in excessive deformation of the support pile and large amount of base heave.

[0040] Both the telescopic outer cylinder 301 and the telescopic inner cylinder 302 can be made of steel. The first connecting piece 1, the second connecting piece 4, the fixed plate 201, and the movable plate 202 can also be made of steel.

[0041] Based on the above technical solution, in the technical solution provided in this embodiment, the movable end 2 also includes a guide outer cylinder 204 and a guide inner cylinder 205. The guide outer cylinder 204 and the guide inner cylinder 205 are fixed to the fixed plate 201 and the movable plate 202 respectively, and the guide inner cylinder 205 is slidably sleeved on the inner side of the guide outer cylinder 204.

[0042] For example, see Figure 1 , Figure 3Two jacks 203 are provided between the fixed plate 201 and the movable plate 202. The two jacks 203 are parallel, that is, the moving ends of the two jacks 203 move in parallel directions, which makes the movement of the movable plate 202 more stable.

[0043] Secondly, two guide outer cylinders 204 and two guide inner cylinders 205 are provided between the fixed plate 201 and the movable plate 202. The two guide inner cylinders 205 are slidably sleeved inside the two guide outer cylinders 204. The sliding direction of the guide inner cylinders 205 is parallel to the moving direction of the moving end of the jack 203. Through the cooperation of the guide outer cylinders 204 and the guide inner cylinders 205, the moving stability of the movable plate 202 can be further improved.

[0044] This embodiment provides a specific implementation method for the telescopic component 3:

[0045] The telescopic component 3 may include a telescopic outer cylinder 301 and a telescopic inner cylinder 302. The telescopic inner cylinder 302 is slidably sleeved inside the telescopic outer cylinder 301. A sliding groove 303 is provided on the side wall of the telescopic inner cylinder 302. A slider 304 is slidably fitted in the sliding groove 303. A spring 305 is provided in the sliding groove 303. The two ends of the spring 305 are respectively connected to the inner wall of the sliding groove 303 and the slider 304.

[0046] For example, see Figure 3-4 The telescopic inner cylinder 302 can slide within the telescopic outer cylinder 301. A radial sliding groove 303 is provided on the side wall of the telescopic inner cylinder 302, and the slider 304 can slide within the sliding groove 303. When the spring 305 is in its natural state, the slider 304 is partially exposed outside the sliding groove 303. At this time, the slider 304 can limit the telescopic outer cylinder 301, preventing it from moving to the left. That is, the telescopic component 3 cannot shorten at this time, only extend, thus preventing the two uprights from closing relative to each other and providing support for the uprights. Even if the telescopic outer cylinder 301 can move to the right to the next slider 304, causing the telescopic component 3 to extend a certain distance, the telescopic component 3 still cannot shorten, thus maintaining its supporting function for the uprights.

[0047] When it is necessary to slide the telescopic outer cylinder 301 to the left, simply press the slider 304. The telescopic outer cylinder 301 can press the slider 304 into the inner side of the sliding groove 303.

[0048] The inner telescopic cylinder 302 has a set of sliding grooves 303 evenly spaced along its circumference on its side wall. Correspondingly, there is a set of sliders 304. The set of sliders 304 can simultaneously limit the movement of the outer telescopic cylinder 301, making the limiting effect more stable.

[0049] Multiple sets of sliding grooves 303 can be evenly spaced along the axial direction on the side wall of the telescopic inner cylinder 302, allowing the telescopic component 3 to maintain various different lengths.

[0050] This embodiment also provides another specific implementation method for the telescopic component 3:

[0051] For example, see Figure 5 The telescopic component 3 may include a telescopic outer cylinder 301, a telescopic inner cylinder 302, and a positioning screw. The telescopic inner cylinder 302 is slidably sleeved inside the telescopic outer cylinder 301. Multiple screw holes 306 are evenly spaced along the axial direction on the side wall of the telescopic inner cylinder 302. A positioning hole 307 is provided on the side wall of the telescopic outer cylinder 301. By aligning the positioning hole 307 with one of the screw holes 306, and then threading the positioning screw through the positioning hole 307 and screwing it into the screw hole 306, the telescopic outer cylinder 301 and the telescopic inner cylinder 302 can be locked and fixed. By aligning the positioning hole 307 with screw holes 306 at different positions, the length of the telescopic component 3 can be adjusted.

[0052] In the technical solution provided in this embodiment, the active end 2 also includes a protective cover 5.

[0053] For example, see Figure 6-7 The protective cover 5 has openings at both ends. The left end of the protective cover 5 is fixed to the movable plate 202. The jack 203, the outer guide cylinder 204, and the inner guide cylinder 205 are all located inside the protective cover 5. The protective cover 5 can play a protective role and prevent soil and other impurities from interfering with the operation of the jack 203, the outer guide cylinder 204, and the inner guide cylinder 205.

[0054] A fence 7 can be installed on the fixing plate 201. That is, the fence 7 is open at both ends, the right end of the fence 7 is fixed to the fixing plate 201, and the fence 7 is located inside the protective cover 5. At the same time, the jack 203, the guide outer cylinder 204, and the guide inner cylinder 205 are all located inside the fence 7.

[0055] The right end of the protective cover 5 can be fitted onto the outside of the fence 7. This way, when the position of the movable plate 202 is adjusted by the jack 203, the fence 7 can avoid gaps between the protective cover 5 and the fixed plate 201, thereby improving its protective performance.
