[0033] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0034] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this utility model based on specific circumstances.

[0035] Example 1

[0036] This embodiment provides a trench support structure for a municipal pipeline project, comprising:

[0037] Four columns 1 are respectively located at the four corners of the rectangle.

[0038] The retaining mechanism is arranged along the longitudinal side of the rectangle.

[0039] The supporting mechanism is arranged along the horizontal sides of the rectangle.

[0040] See also Figure 1 The four pillars are the first pillar (upper left corner), the second pillar (lower left corner), the third pillar (upper right corner), and the fourth pillar (lower right corner). The line connecting the first and second pillars is arranged along the horizontal side of the rectangle, and the line connecting the third and fourth pillars is arranged along the other horizontal side of the rectangle. In other words, a support mechanism is provided between the first and second pillars, and a support mechanism is also provided between the third and fourth pillars.

[0041] Correspondingly, the line connecting the first and third columns is arranged along the longitudinal side of the rectangle, and the line connecting the second and fourth columns is arranged along the other longitudinal side of the rectangle. In other words, a retaining mechanism is provided between the first and third columns, and between the second and fourth columns, thus forming a complete support structure.

[0042] See also Figure 2 The supporting mechanism includes a telescopic part, and positioning holes are provided at both ends of the telescopic part. A fixed pin 4 is inserted into the positioning hole. A first slide groove 2 is vertically fixed on the side wall of the column 1. A plurality of pin holes 3 are evenly spaced vertically on both side walls of the first slide groove 2. The fixed pin 4 is inserted into the pin hole 3.

[0043] It is worth noting that the four columns 1 are all provided with a first slide groove 2, and the first slide grooves 2 on the side walls of the first column and the second column need to be arranged opposite to each other to facilitate the two ends of the telescopic member to be inserted into the first slide grooves of the first column and the second column respectively. Similarly, the same is true for the other two columns.

[0044] Based on the above structure, the trench support structure provided in this embodiment can adjust the length of the support mechanism and then adjust the support width by telescoping the telescopic parts, thereby increasing the application range of the support structure, improving construction quality, and reducing construction errors.

[0045] When installing the telescopic member, the end of the telescopic member is slid into the first chute 2 to the desired height. The fixing latch 4 is then inserted through the latch hole 3 at the corresponding height and into the positioning hole, securing the end of the telescopic member in the latch hole 3. This completes the installation of the telescopic member, and the height of the telescopic member can be adjusted at any time. Conversely, the fixing latch 4 can be removed to complete the disassembly of the telescopic member. The operation is simple and convenient.

[0046] See also Figure 2 In this embodiment, the telescopic part can include a tube support 7, a sleeve 6, and a locking rod; the tube support 7 is slidably sleeved in the sleeve 6, and a plurality of inner locking holes are evenly spaced along the length direction on the side wall of the tube support 7, and an outer locking hole is provided on the side wall of the sleeve 6, and one end of the locking rod passes through the outer locking hole and the inner locking hole in sequence.

[0047] When the length of the telescopic part needs to be adjusted, the locking rod is removed, and then the pipe support 7 is slid to change the relative position of the pipe support 7 and the sleeve 6. When the pipe support 7 slides to the appropriate position, the locking rod is inserted into the outer locking hole and the inner locking hole at the corresponding position in sequence, and the pipe support 7 and the sleeve 6 can be fixed again to complete the length adjustment of the telescopic part. The operation is simple and convenient.

[0048] To improve the adjustment accuracy of the telescopic member, in this embodiment, the telescopic member further includes a screw 5. The end of a sleeve 6, remote from the pipe support 7, is provided with an internal thread, with which the screw 5 is threadedly engaged. By rotating the screw 5, the relative position of the screw 5 and sleeve 6 can be adjusted. Since the length of the screw 5 changes little as it rotates, the screw 5 can improve the adjustment accuracy of the telescopic member.

[0049] It should be noted that the end of the pipe support 7 away from the sleeve 6 has a positioning hole, into which a fixing pin 4 is inserted. Simultaneously, the end of the screw 5 away from the sleeve 6 also has a positioning hole, into which a fixing pin 4 is inserted. These two fixing pins 4 allow the ends of the telescopic member to be mounted in the first chute 2 of the two columns, respectively.

[0050] To enhance the stability of the telescopic member, the end of the tube support 7 away from the sleeve 6 is adapted to fit within the first chute 2, allowing the tube support 7 to slide smoothly up and down within the first chute 2. A stopper is coaxially fixed to the end of the screw rod 5 away from the sleeve 6, and the stopper fits within the first chute 2. This allows the screw rod 5 to slide smoothly up and down within the first chute 2 via the stopper.

[0051] For example, the limiting member can be a circular plate structure. The outer diameter of the circular plate structure is adapted to the first chute 2 so that the circular plate structure can slide up and down smoothly in the first chute 2 and the circular plate structure will not be affected by the rotation of the screw 5.

[0052] See also Figure 3-4 In this embodiment, the retaining mechanism includes five lap plates. For example, the ends of the lap plates are mounted on the first and third columns, respectively. The five lap plates are arranged in parallel along a vertical interval, and retaining plates 9 are positioned between adjacent lap plates. The retaining plates 9 provide a retaining function.

[0053] Specifically, the lap plate may include three angle steel fixing pins 10 and two angle steels 8. The angle steel 8 is provided with a plurality of fixing holes evenly spaced along the length direction. The angle steel fixing pins 10 are simultaneously inserted into the fixing holes of the two angle steels 8 so that the two angle steels 8 partially overlap. When it is necessary to adjust the length of the lap plate, the angle steel fixing pins 10 are removed, the relative positions of the two angle steels 8 are adjusted, and then the angle steel fixing pins 10 are inserted into the corresponding fixing holes of the two angle steels 8 to adjust the length of the lap plate. The length of the retaining mechanism can then be adjusted to further enhance the scope of application of the support structure. Among them, the cross-section of the angle steel 8 is an L-shaped structure, and the angle steel fixing pins 10 and the angle steel 8 can together form a clamping groove, which can limit the retaining plate 9. In some other embodiments, the retaining plate 9 can be bonded and fixed to the angle steel 8, and the structure is more solid.

[0054] When encountering an existing pipeline crossing the trench, the horizontal length of the retaining mechanism can be changed by adjusting the position of the angle steel fixing pin 10, thereby protecting the existing pipeline.

[0055] In order to be able to adjust the height position of the angle steel 8 up and down, in this embodiment, the column 1 is an H-shaped steel column, and a second slide groove is formed on the side wall of the column 1. A plurality of overlapping holes are provided on both side walls of the second slide groove along the vertical intervals, and a limit pin 12 is inserted in the overlapping hole. Sliders 11 are fixed at both ends of the overlapping plate, and the sliding member 11 slides in cooperation with the second slide groove, and the sliding member 11 overlaps the limit pin 12.

[0056] It's worth noting that all four columns 1 have second chute grooves formed on their sidewalls. These grooves on the first and third columns are positioned opposite each other, allowing the sliding members 11 at each end of the lap plate to enter the second chute grooves of the first and third columns, respectively. Similarly, the same principle applies to the other two columns. This allows the height of the lap plate to be adjusted by sliding the sliding members 11 up and down within the second chute grooves.

[0057] As needed, in this embodiment, the columns 1 , the supporting mechanism, the angle steels 8 , the retaining plates 9 , the first chute 2 , etc. are all steel structures.

[0058] The sliding member 11 can be a U-shaped steel plate with the U-shaped groove opening toward the angle steel 8. The U-shaped groove is adapted to the second chute so that the U-shaped steel plate can slide up and down in the second chute. The end of the angle steel 8 can be clamped in the U-shaped groove by a square wood. Clamping the end of the angle steel 8 in the U-shaped groove by the square wood not only simplifies the structure but also makes installation and removal very convenient.

[0059] In summary, the construction process of the trench support structure provided in this embodiment may include the following steps:

[0060] Step 1: Install H-shaped steel column 1 to 0.5m below the design elevation, or install column 1 in stages according to height to 0.5m below the excavation depth;

[0061] Step 2: When the excavation depth reaches 1.2m, place the end of the pipe support 7 in the first chute 2 at the designed height and secure it with the fixing pin 4. Then adjust the length of the telescopic member using the sleeve 6 and rotate the screw 5 for fine adjustment until the telescopic member reaches the designed groove width and then secure it.

[0062] Step 3: Place the end of the angle steel 8 in the U-shaped groove, adjust it to the design elevation, and then fix it with the limit pin 12. By changing the position of the angle steel fixing pin 10, adjust the lap plate to the appropriate length, then place the retaining plate 9 to the soil side of the angle steel 8, and finally fill the U-shaped groove with square wood to keep the angle steel 8 fixed;

[0063] Step 4: Excavate and support at the same time, alternating between excavation and placement of retaining plates 9. Each time the height of the retaining plates 9 is controlled at about 0.6m, and steps 2 and 3 are repeated until the trench design elevation is reached. If the soil is soft or it rains, the retaining plates 9 should be placed in time and the support structure should be strengthened.

[0064] Step 5: During trench backfilling, the dismantling of the support structure and retaining plate 9 and backfilling should be carried out alternately, layer by layer from bottom to top. After backfilling to the roadbed elevation, the H-shaped steel column 1 can be removed.
