DETAILED DESCRIPTION

[0031] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0032] Reference Figures 1 to 10 The present embodiment provides an integrated support structure for municipal pipe network construction under adverse geological conditions, including a first column 1, a second column 2, a splint 3 and a bendable limit assembly 4. The first column 1 is provided with a plurality of columns arranged in a linear array, and the second column 2 is provided with a plurality of columns arranged in a linear array; the outer sides of the first column 1 and the second column 2 are provided with splints 3 respectively. The first column 1 and the second column 2 are respectively arranged at the inner wall positions on both sides of the groove 0. There are two splints 3, one splint 3 is placed between the first column 1 and the inner wall on one side of the groove 0, and the other splint 3 is placed between the second column 2 and the inner wall on the other side of the groove 0. The limit assembly 4 is used to apply a supporting force between the first column 1 and the second column 2, so as to achieve a support effect, avoid the collapse of the groove 0, and ensure the safety of the construction work.

[0033] Reference Figure 1 and Figure 2The first column 1 and the second column 2 are connected by a limit assembly 4. The clamping plate 3 is in a straight plate structure, the first column 1 is in a longitudinally arranged straight column shape, and the second column 2 is in a longitudinally arranged straight column shape, so as to ensure that the first column 1 and the corresponding clamping plate 3 are closely fitted, and the second column 2 and the corresponding clamping plate 3 are closely fitted, and further ensure that the first column 1 and the corresponding clamping plate 3 are uniformly stressed, and the second column 2 and the corresponding clamping plate 3 are uniformly stressed, so as to avoid stress concentration, improve the support effect, and increase the safety of use and service life.

[0034] Reference Figure 1 and Figure 2 , the two clamping plates 3 are arranged parallel to each other; the first column 1 and the second column 2 are arranged parallel to each other.

[0035] Reference Figure 1 and Figure 2 , there are several limit assemblies 4; several limit assemblies 4 are arranged in a longitudinal array.

[0036] Reference Figure 2 The limiting assembly 4 includes a cross brace rod 42 and a limiting rod 41.

[0037] Reference Figure 2 to Figure 4 Each limiting assembly 4 includes two cross braces 42 and a limiting rod 41. The two cross braces 42 are respectively arranged at both ends of the limiting rod 41, and the cross braces 42 are rotatably connected to the limiting rod 41. For example, the cross braces 42 and the limiting rod 41 are connected by hinges, and the hinges are installed on the surface of the cross braces 42. The two cross braces 42 are respectively connected to the first column 1 and the second column 2. Figure 3 , wherein one of the cross braces 42 is vertically fixedly connected to the first column 1 (for example, fixedly connected by bolts); Figure 4 Another cross brace 42 is vertically fixedly connected to the second column 2 (for example, fixedly connected by bolts).

[0038] In the same limiting assembly 4, the cross brace rod 42 and the limiting rod 41 are arranged in an I-shape.

[0039] Reference Figures 5 to 10 The limiting rod 41 includes a first rod body 411 and a second rod body 412; the end of the first rod body 411 and the end of the second rod body 412 are rotatably connected (for example, connected by a hinge). Figure 6 When the first column 1 and the second column 2 are close to each other, the limiting rod 41 is bent to adapt to the distance between the first column 1 and the second column 2, thereby reducing the space occupied by the utility model to facilitate the storage and transportation of the utility model.

[0040] Reference Figure 7The cross section of the first rod body 411 is rectangular, and the cross section of the second rod body 412 is n-shaped, so when the limit rod 41 is bent, the second rod body 412 is buckled on the surface of the first rod body 411. The first rod body 411 is in the shape of a straight rod, and the second rod body 412 is in the shape of a straight rod.

[0041] Reference Figure 8 and Fig. 9 The limiting rod 41 also includes a limiting sleeve 413, which is in the shape of a straight tube. The limiting sleeve 413 is sleeved on the surface of the second rod body 412 and is slidably connected. The limiting sleeve 413 can slide back and forth along the length direction of the second rod body 412. A limiting through hole 4131 is provided at one end of the limiting sleeve 413 close to the first rod body 411, and a limiting screw hole 4111 is provided on the first rod body 411. A limiting bolt 414 is detachably connected in the limiting screw hole 4111. The limiting bolt 414 and the limiting screw hole 4111 are used to limit the position of the limiting sleeve 413: when the limiting sleeve 413 is sleeved at the hinged position of the first rod body 411 and the second rod body 412, the limiting rod 41 can be prevented from bending, thereby stably applying a supporting force to the first column 1 and the second column 2.

[0042] Reference Fig.10 A countersunk hole 4112 is provided at the end of the limiting screw hole 4111, and the countersunk hole 4112 is used to provide an accommodating space for the limiting bolt 414 during storage and transportation of the utility model.

[0043] Production and transportation steps: ① manufacture the components of the utility model; ② assemble the first column 1, the second column 2, and the clamping plate 3; ③ assemble the first rod 411, the second rod 412, the limiting sleeve 413, and the cross brace 42, and the limiting sleeve 413 is completely sleeved on the surface of the second rod 412 instead of being sleeved on the surface of the first rod 411; ④ assemble the cross brace 42, the first rod 411, and the second rod 412; ⑤ install the limiting bolt 414 in the limiting screw hole 4111, so that the column head of the limiting bolt 414 is placed in the countersunk hole 4112 (refer to Fig.10 );⑥ Push the first column 1 and the second column 2 closer to each other, so that the limit rod 41 enters the fold and bends, and the utility model enters the folded state (refer to Figure 6 );⑦ Use ropes to tie up the utility model in the folded state, and then load and transport the utility model.

[0044] On-site construction steps: ① Dig trench 0; ② Untie the rope and remove the limit bolt 414 from the limit screw hole 4111; ③ Pull the first column 1 and the second column 2 apart, and at the same time unfold the limit rod 41; when the two clamps 3 are respectively in contact with the two inner walls of the trench 0, the limit rod 41 is in a straightened state; ④ Move the limit sleeve 413 until the limit sleeve 413 is located at the hinge position of the limit rod 41, at this time the limit through hole 4131 and the limit screw hole 4111 are aligned; ⑤ Install the limit bolt 414 in the limit through hole 4131 and the limit screw hole 4111, so that the limit sleeve 413 cannot slide along the limit rod 41.

[0045] Reference Fig.11 In the on-site construction step ③, it is necessary to design the length of the limit rod 41 in advance according to the construction drawings to ensure that the limit rod 41 is just straightened when the splint 3 fits the inner wall of the groove 0. For example, the construction drawings plan to excavate a groove 0 with a width of 2.5 meters, then the length of the limit rod 41 = 2.5 meters - (the thickness of the splint 3 * 2) - the thickness of the first column 1 - the thickness of the second column 2 - (the thickness of the cross brace 42 * 2) - (the thickness H * 2 of the bottom plate of the hinge connected to the limit rod 41). The end of the limit rod 41 abuts against the bottom plate of the hinge (the abutment will accelerate the wear speed of the end of the limit rod 41, so the utility model cannot be folded and unfolded frequently. Since the utility model will not be reused after being buried in the groove 0 at a later stage, the number of folding and unfolding is within 5 times, which is enough to meet the use requirements), so that the cross brace 42 transmits the supporting force to the limit rod 41 through the bottom plate of the hinge to reduce the load-bearing pressure of the hinge shaft and improve the safety performance.

[0046] The utility model has a simple structure and reliable functions, and supports the groove 0 through the first column 1, the second column 2, the clamping plate 3 and the limit assembly 4. The utility model realizes folding and unfolding through an integrated structure: it can be folded during storage and transportation to reduce space occupation and improve convenience; it can be quickly unfolded at the construction site to improve construction efficiency, and has broad market prospects.
