Description

Technical Field

[0001] This application relates to the field of municipal construction technology, and in particular to a trench support structure for municipal drainage pipelines. Background Technology

[0002] In the construction of urban municipal drainage pipelines, problems such as complex engineering geology, small construction working area, and short construction period are often encountered. If the construction is carried out in accordance with conventional construction methods, it is difficult to ensure the safety of buildings adjacent to the working area. Therefore, trench support structures are used to support the installation of auxiliary water pipelines in the trench.

[0003] Chinese Patent No. CN208455646U discloses a trench support structure for municipal drainage pipelines, including support piles, support beams, and adjustment devices. The support beams are connected between the support piles, and the adjustment devices are connected to the support beams to adjust them.

[0004] Although the aforementioned patents have improved the shortcomings of the transmission bracket's inability to adjust its width, the single support beam configuration results in poor structural stability. In response to the aforementioned related technologies, the applicant proposes an adjustable-width pit support structure, which effectively improves the stability of the support structure. Utility Model Content

[0005] In order to improve the stability of the adjustable-width trench support structure, this application provides a trench support structure for municipal drainage pipelines.

[0006] The technical solution for a municipal drainage pipeline trench support structure provided in this application is as follows:

[0007] A municipal drainage pipeline trench support structure includes supports on both sides of the trench. At the top of one support, vertically spaced crossbeams extend towards the opposite support. The opposite support has a sliding structure extending laterally from the corresponding crossbeam. The sliding structure has multiple connected points that pass through and slidably connect to the crossbeams, with the multiple crossbeams and the corresponding sliding structure's connection points arranged in an intersecting direction. Adjustment structures are vertically inserted on both sides of the sliding structure. The adjustment structures have variable cross-sections vertically, with the variable cross-section sides abutting against the crossbeams and one side of the corresponding sliding structure support. A pressure-applying structure is rotatably connected above the adjustment structure and screwed to one side of the corresponding sliding structure support.

[0008] By adopting the above technical solution, multiple connection points arranged in a row form a stable connection between the beam and the sliding structure, which enhances the stability of the entire support structure. When pressure is applied, the pressure structure can further enhance the tightness of the adjustment structure, thereby improving the load-bearing capacity of the entire support structure. This ensures that while it has adjustment capabilities, the adjustment capabilities do not affect the structural strength, thus giving it stable characteristics.

[0009] Preferably, the sliding structure includes extension blocks and connecting slide rods. The extension blocks are respectively fixed to the brackets on one side of the opposite crossbeam. The connecting slide rods are respectively fixed to the extension blocks, and the connecting slide rods corresponding to the upper extension blocks are vertically spaced and pass through the corresponding crossbeams, while the connecting slide rods corresponding to the lower extension blocks are horizontally spaced and pass through the corresponding crossbeams.

[0010] Preferably, the end faces of the extension ends of the lower crossbeam are horizontally misaligned to the left and right, and the extension blocks are misaligned to correspond to the extension ends of the crossbeam.

[0011] Preferably, the adjusting structure includes abutment wedges and friction discs. The abutment wedges are vertically inserted through the connecting slide rod. The two end faces of the abutment wedges corresponding to the crossbeams and the abutment wedges are respectively inclined in opposite directions, and the abutment wedges corresponding to the lower connecting slide rods are horizontally offset. The abutment wedges are fixedly connected to each other. The friction discs abut against both sides of the abutment wedges and are sleeved on the connecting slide rods. The friction discs abut against the corresponding crossbeams or extension blocks.

[0012] By adopting the above technical solution, the abutment wedges are fixedly connected to each other, so that the force can be evenly distributed on multiple support points. This not only improves the bearing capacity of the support structure, but also effectively prevents deformation or damage caused by excessive local stress. The abutment wedges are fixedly connected to each other, so that the force friction disc is sleeved on the connecting slide rod and abuts against both sides of the abutment wedge. The friction disc has a lubrication groove on the side corresponding to the abutment wedge, which is filled with grease.

[0013] Preferably, the adjustment structure further includes a lubrication groove, which is located on the side of the friction disc that abuts the wedge block, and contains lubricating grease.

[0014] Preferably, the pressure-applying structure includes a pressure-applying screw and a screw lever. The pressure-applying screw is rotatably connected to the upper abutment wedge block, and the pressure-applying screw is screwed and passes upward through a bracket on one side of the corresponding extension block. The screw lever passes through and is slidably connected to the top end of the pressure-applying screw.

[0015] Preferably, the lower abutting wedges are equidistantly arranged on both sides of the upper abutting wedge.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. Multiple connection points arranged in a row form a stable connection between the beam and the sliding structure, which enhances the stability of the entire support structure. When pressure is applied, the pressure structure can further enhance the tightness of the adjustment structure, thereby improving the load-bearing capacity of the entire support structure. This allows it to have adjustment capabilities without affecting the structural strength, thus giving it stable characteristics.

[0018] 2. The wedges are fixedly connected to each other, so that the force can be evenly distributed on multiple support points. This not only improves the load-bearing capacity of the support structure, but also effectively prevents deformation or damage caused by excessive local stress.

[0019] 3. The abutting wedges are fixedly connected to each other, so that the force friction disc is sleeved on the connecting slide rod and abuts against both sides of the abutting wedges. The friction disc has a lubrication groove on the side corresponding to the abutting wedge, which is filled with grease. Attached Figure Description

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses a support structure for municipal drainage pipeline trenches, referring to... Figure 1 , 2 It includes supports 1 located on both sides of the pit. The supports 1 are retractable and can be fixed to the ground. The top of the side supports 1 is provided with vertically spaced crossbeams 2 extending toward the opposite side supports 1. The opposite side supports 1 have sliding structures 3 corresponding to the transverse extensions of the crossbeams 2, so that the two sides are connected to each other and generate a certain strength.

[0026] Reference Figure 2 , 3 The sliding structure 3 includes an extension block 31 and a connecting slide rod 32. The extension blocks 31 are fixed to the bracket 1 on one side of the crossbeam 2. The connecting slide rods 32 are fixed to the extension blocks 31. The connecting slide rods 32 corresponding to the upper extension blocks 31 are vertically spaced and pass through the corresponding crossbeam 2. The connecting slide rods 32 corresponding to the lower extension blocks 31 are horizontally spaced and pass through the corresponding crossbeam 2. This makes the arrangement direction of the upper connecting slide rods 32 intersect with the arrangement direction of the lower connecting slide rods 32, thereby achieving higher connection strength. The end face of the extension end of the lower crossbeam 2 is horizontally offset to the left and right. The extension blocks 31 are offset to the extension end of the crossbeam 2, thereby having better torsional strength and further enhancing its stability.

[0027] Reference Figure 1 , 3 The distance between the two side supports 1 is adjusted by the adjustment structure 4. The adjustment structure 4 includes abutment wedges 41, friction discs 42 and lubrication grooves 43. The abutment wedges 41 are vertically inserted through the connecting slide rod 32. The abutment wedges 41 are inclined in opposite directions to the crossbeam 2 and the two end faces of the abutment wedges 41 respectively. The abutment wedges 41 corresponding to the lower connecting slide rod 32 are horizontally offset. The abutment wedges 41 are fixedly connected to each other. The lower abutment wedges 41 are equidistantly arranged on both sides of the upper abutment wedges 41, so that the force of the upper abutment wedges 41 can be evenly transmitted to the lower.

[0028] Reference Figure 1 , 3 The abutting wedge 41 is driven to rise and fall by the pressure structure 5. The pressure structure 5 includes a pressure screw 51 and a screw lever 52. The pressure screw 51 is rotatably connected to the abutting wedge 41 above, and the pressure screw 51 is screwed and passes upward through the bracket 1 on one side of the corresponding extension block 31. The screw lever 52 passes through and is slidably connected to the top end of the pressure screw 51.

[0029] Reference Figure 1 , 3 The friction discs 42 abut against both sides of the abutting wedges 41 and are sleeved on the connecting slide rods 32. The friction discs 42 abut against the corresponding crossbeams 2 or extension blocks 31. The friction discs 42 avoid direct contact with the crossbeams 2, which allows the crossbeams 2 to be made of materials with higher hardness. The lubrication grooves 43 are opened on the side of the friction discs 42 corresponding to the abutting wedges 41. The lubrication grooves 43 are filled with grease, so that the friction surface of the friction discs 42 is protected from corrosion and hard friction.

[0030] The working process of this application is as follows: the support 1 is placed in the tunnel and the screw lever 52 is rotated so that the screw lever 52 drives the abutment wedge 41 to rise or fall. When the abutment wedge 41 falls, the minimum gap between the two supports 1 becomes smaller and cannot be retracted. The support 1 is inserted into the ground and a retaining plate is installed to support the stability of the tunnels on both sides.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
