Technical Field
[0001] The utility model relates to the technical field of foundation pit support, in particular to a reusable standardized supporting device for municipal use. Background Art
[0002] In traditional municipal pipeline projects, foundation pits such as trenches and inspection wells mostly use simple support systems or steel sheet pile support systems. The simple support system is suitable for small foundation pits with shallow depth and small width in soil layers with good soil quality. However, when it comes to soft soil layers with poor stability, such as silt and silty soil, the simple support system has great safety hazards and cannot be applied.
[0003] Although the steel sheet pile support system can be effectively applied to pipe trenches and inspection well foundation pit support in soft soil layers, the minimum length of the steel sheet pile is 6m. For small foundation pits with shallow depth and small width, excavators need to be used throughout the support operation, which has the problems of high machinery costs, labor-intensive and time-consuming. In addition, the traditional support system has a low reuse rate of other components except steel sheet piles. Utility Model Content
[0004] The purpose of the present utility model is to provide a reusable standardized supporting device for municipal use, so as to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a reusable standardized support device for municipal use, comprising a plurality of support plates, one side wall of each of the plurality of support plates being fixedly connected to an insert plate, another side wall of each of the plurality of support plates being provided with a slot, the bottom of each side wall of each of the plurality of support plates being fixedly connected to a plurality of arc-shaped silt plates, and a plurality of limit insert rods penetrating the middle of each of the plurality of support plates;
[0006] The middle part of one side wall of multiple support plates is fixedly connected with a support, and a first support rod and a second support rod are provided between two opposite supports. A metal tube is passed through one end of the second support rod, and a glass tube is provided inside the metal tube. The interior of the glass tube is filled with a colored solution. A white cotton board is fixedly embedded in the top end of the metal tube, and a plurality of water-conducting cotton strips are fixedly connected to the bottom end of the white cotton board.
[0007] As a preferred technical solution of the present invention, the size of the plug-in board matches the size of the slot, and adjacent plug-in boards are connected through the slots.
[0008] Through the above technical solution, adjacent support plates can be spliced and assembled by pushing them horizontally, reducing the difficulty and cost of the operation.
[0009] As a preferred technical solution of the present utility model, a striking plate is fixedly connected to one end of each of the plurality of limiting insertion rods, a plurality of through holes are formed in the middle of the support plate, and the plurality of limiting insertion rods respectively penetrate through the plurality of through holes, and an interference fit is provided between the limiting insertion rods and the through holes.
[0010] Through the above technical solution, the operator can use a tool to hammer the striking plate, then push the limiting insertion rod into the side wall of the foundation pit and insert it into the soil layer for further limiting and fixing, and the interference fit can prevent the limiting insertion rod from slipping out flexibly by itself.
[0011] As a preferred technical solution of the present utility model, a plurality of insertion holes are formed at one end of the first support rod, and the bottom of the metal cylinder penetrates through one of the insertion holes.
[0012] Through the above technical solution, the plurality of insertion holes can be adjusted to adjust the distance between the first support rod and the second support rod to adapt to different foundation pit widths.
[0013] As a preferred technical solution of the present utility model, a central hole is formed at the center of the metal cylinder, and the glass tube is fixedly inserted through the inner wall of the central hole.
[0014] Through the above technical solution, the outer wall of the glass tube fully fits with the inner wall of the central hole, so that after the metal cylinder undergoes obvious dislocation deformation, the glass tube can be broken.
[0015] As a preferred technical solution of the present utility model, threads are provided at both the top and bottom of the outer wall of the metal cylinder, and nuts are threadedly connected to both the top and bottom of the outer wall of the metal cylinder.
[0016] Through the above technical solution, with the help of the nuts at the top and bottom, the first support rod and the second support rod after penetration can be fixed.
[0017] As a preferred technical solution of the present utility model, the plurality of water guide cotton strips are respectively attached to the four side walls of the glass tube.
[0018] Through the above technical solution, after the glass tube is broken, the colored solution flowing out in any direction can be adsorbed and penetrated by the water guide cotton strip, and thus transmitted to the white cotton board at the top.
[0019] As a preferred technical solution of the present utility model, rubber sleeves are embedded at the other ends of the first support rod and the second support rod, and the rubber sleeves are snap-fitted with the grooves formed in the middle of the support.
[0020] Through the above technical solution, the rubber sleeves increase the friction and are more stable when inserted into the grooves.
[0021] Compared with the prior art, the beneficial effects of the present utility model are:
[0022] 1. The utility model realizes quick splicing, assembly and disassembly by means of the cooperation between the inserting plate and the inserting slot, which reduces the operation difficulty and cost. Secondly, the supporting plate has a stable structure and wide generality, and is not easy to deform or be damaged during the supporting use. Therefore, it can be recycled after the current support is completed, improving the reuse rate of local parts. The arc-shaped silt plate can increase the contact surface with the soft soil layer at the bottom of the foundation pit. The plate is thinner, with stable support and reduced collapse. The cooperating limiting inserting rod can be inserted into the silt layer after shaping to further increase the support stability.
[0023] 2. By arranging a glass tube in the central hole of the metal cylinder, the utility model can conduct real-time detection in the force direction of the supporting plate. When the extrusion force between two opposite supporting plates is too large and obvious dislocation deformation occurs, the colored solution will penetrate into the white cotton board due to the fracture of the glass tube. By observing the white cotton board, the degree of mutual extrusion force can be confirmed. When the pressure is too large and there is a risk of collapse, timely reinforcement and adjustment are required. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Please refer toFigures 1 to 4 , the present utility model provides a technical solution for a reusable standardized support device for municipal use:
[0031] Embodiment 1:
[0032] According to Figure 1 、 Figure 2 As shown, a reusable standardized support device for municipal use includes a plurality of support plates 1. One side wall of each of the plurality of support plates 1 is fixedly connected with an insertion plate 3, and the other side wall of each of the plurality of support plates 1 is provided with a slot 2. The bottom of one side wall of each of the plurality of support plates 1 is fixedly connected with a plurality of arc-shaped silt plates 12. The arc-shaped silt plates 12 are placed on the silt surface, increasing the contact area and making the support more stable. A plurality of limiting insertion rods 10 penetrate through the middle of each of the plurality of support plates 1, and the limiting insertion rods 10 are inserted into the soft soil layer.
[0033] The size of the insertion plate 3 matches the size of the slot 2. The adjacent insertion plates 3 and slots 2 are inserted and connected. One end of each of the plurality of limiting insertion rods 10 is fixedly connected with a striking plate 11. A plurality of through holes are formed in the middle of the support plate 1, and the plurality of limiting insertion rods 10 respectively penetrate through the plurality of through holes. The limiting insertion rods 10 and the through holes are in interference fit. A plurality of jacks 13 are formed at one end of the first support rod 7, and the bottom of the metal cylinder 9 penetrates through one of the jacks 13.
[0034] During specific use, for the reusable standardized support device for municipal use of the present utility model, the operator can vertically arrange the plurality of support plates 1 on both sides of the trench. With the cooperation of the insertion plate 3 and the slot 2, the mutual splicing and combination of the plurality of support plates 1 are realized. The arc-shaped silt plates 12 are laid on the inner bottom wall of the trench, with a large contact area with the wet soft soil layer and silt, playing a good supporting role. After the setting and assembly are completed, the plurality of striking plates 11 can be manually knocked to hammer the limiting insertion rods 10 into the silt soft layer on the side wall of the trench to play a limiting and positioning role. Subsequently, the first support rod 7 and the second support rod 8 are combined with each other, and the fixation is realized by inserting the metal cylinder 9. In this way, with the support of the first support rod 7 and the second support rod 8, the support plates 1 on both sides can stably support the trench and the inspection well foundation pit. After the support is used up, the first support rod 7 and the second support rod 8 can be detached, so that the mutually combined support plates 1 are separated, and the support plates 1 are recycled and reused.
[0035] Embodiment 2:
[0036] On the basis of Embodiment 1, as Figure 1 and Figure 3 、 Figure 4As shown in the figure, supports 4 are fixedly connected to the middle parts of one side walls of multiple support plates 1. A first strut 7 and a second strut 8 are arranged between two opposite supports 4. A metal cylinder 9 penetrates through one end of the second strut 8. A glass tube 14 is arranged inside the metal cylinder 9. A colored solution 18 is filled inside the glass tube 14. A white cotton board 15 is fixedly embedded at the top end of the metal cylinder 9. A plurality of water-conducting cotton strips 16 are fixedly connected to the bottom end of the white cotton board 15.
[0037] A central hole 17 is opened at the center of the metal cylinder 9. The glass tube 14 is fixedly inserted through the inner wall of the central hole 17. Threads 20 are opened at both the top and the bottom of the outer wall of the metal cylinder 9. Nuts 19 are threadedly connected to both the top and the bottom of the outer wall of the metal cylinder 9. The plurality of water-conducting cotton strips 16 are respectively attached to four side walls of the glass tube 14. Rubber sleeves 6 are embedded at the other ends of the first strut 7 and the second strut 8. The rubber sleeves 6 are snap-fitted with grooves 5 opened at the middle parts of the supports 4.
[0038] During specific use, for a reusable standardized support device for municipal engineering of the present invention, during the actual support use process, if the pressures on both sides of a foundation pit such as a trench or an inspection well are relatively large and form a strong extrusion on the support plate 1, the extrusion force is directly transmitted to the first strut 7 and the second strut 8, and the two will undergo relative misalignment. The extrusion force generated by the misalignment will be directly transmitted to the metal cylinder 9 inserted between the two. The metal cylinder 9 undergoes slight deformation, which will cause the internal glass tube 14 to be squeezed and broken. In this way, the internal colored solution 18 flows out and wets the plurality of water-conducting cotton strips 16. The water-conducting cotton strips 16 absorb the colored solution 18 and penetrate upward to the white cotton board 15. The operator can regularly check the color of the white cotton board 15 during the construction process. When the color changes, it means that the metal cylinder 9 has undergone misalignment deformation, that is, the extrusion force on both sides is too large, and the support should be strengthened and adjusted in time.
