Description

Technical Field

[0001] This utility model belongs to the field of trench support technology, and specifically relates to a modular trench support system. Background Technology

[0002] Current domestic conventional trench slope protection methods include pile support, sheet pile support, soil nailing and shotcrete support, and retaining plate support. These methods have the following problems: 1. Large-scale pile driving machinery is often required during construction, but the entry and exit of this machinery are limited by site constraints, making it difficult to handle smaller construction areas and resulting in high construction costs; 2. Some construction methods suffer from low efficiency, long construction time, difficulties in material turnover, and potential safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a modular support system for trenches, which solves the technical problems of extended construction period, increased costs, and increased safety risks caused by the inability to slope trenches and the need for support construction.

[0004] This utility model is achieved using the following technical solution: A modular trench support system includes several steel profiles (Type 1) and several telescopic support rods. A steel profile (Type 2) is fixed to one side of each steel profile (Type 1). Several bolt holes (Type 2) are evenly distributed on the side of each steel profile (Type 2) away from the steel profile (Type 1). A slot is installed on the other side of each steel profile (Type 1). Each end of the telescopic support rod is connected to a steel profile (Type 1) through the bolt holes (Type 2). A telescopic support rod is connected between two steel profiles (Type 1) at the top and middle through bolt holes (Type 2). Two steel profiles (Type 1), two steel profiles (Type 2), and two telescopic support rods are defined as a unit. Two units are connected by inserting a retaining plate into the slot.

[0005] In application, the two sets of units are inserted into the slots, and the two sets of units are connected by the retaining plate. A telescopic support rod is connected to the top and middle of the two steel sections of each set of units.

[0006] More preferably, the retractable support rod includes support rod one, support rod two, and support rod three. One end of support rod one is connected to section steel one through bolt hole two, and the other end of support rod one is provided with internal thread one. Support rod two is provided with external threads with different helical directions at both ends. One end of support rod three is connected to another section steel one through bolt hole two, and the other end of support rod three is provided with internal thread two. The bolt directions of internal thread one and internal thread two are different. One end of support rod two is screwed into support rod one, and the other end is screwed into support rod three. In actual use, support rod two can be replaced to support grooves of different widths.

[0007] Preferably, support rod one and support rod three are hinged to steel section two via hinge supports. The hinge support connection facilitates the installation of the telescopic support rod. During installation, support rod one is first hinged to bolt hole two, then support rod two is screwed into support rod one, and then support rod three is assembled with support rod two. Finally, support rod three is hinged to bolt hole two on another steel section two. If the positions of support rod one, support rod two, and support rod three are not suitable during assembly, they can be rotated to facilitate assembly. It is only necessary to ensure that the two hinge supports are at the same height after support rod one and support rod three are hinged to bolt hole two.

[0008] More preferably, the steel section has a plurality of bolt holes evenly arranged thereon, and the two sets of units are connected to the longitudinal support rods through the bolt holes to form a longitudinal support.

[0009] More preferably, a frame unit is formed by combining four sets of units. The frame unit has a size of 2440mm×1220mm. The bolt hole is used to realize the quick connection between the steel sections, and the slot is used for the quick installation of the retaining plate.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0019] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example

[0020] A modular trench support system includes several steel profiles 1 and several telescopic support rods 2. A steel profile 3 is fixed to one side of the steel profile 1. Several bolt holes 31 are evenly arranged on the side of the steel profile 3 away from the steel profile 1. A slot 4 is installed on the other side of the steel profile 1. Each end of the telescopic support rod 2 is connected to a steel profile 1 through the bolt holes 31. A telescopic support rod 2 is connected to the top and middle of two steel profiles 1 through bolt holes 31. Two steel profiles 1, two steel profiles 3, and two telescopic support rods 2 are defined as a unit. Two units are connected by inserting a retaining plate into the slot 4.

[0021] The telescopic support rod 2 includes support rod 1 21, support rod 22 and support rod 3 23. One end of support rod 1 21 is connected to the steel profile 1 through bolt hole 2 31, and the other end of support rod 1 21 is provided with an internal thread 1. Support rod 22 is provided with external threads with different helical directions at both ends. One end of support rod 3 23 is connected to another steel profile 1 through bolt hole 2 31, and the other end of support rod 3 23 is provided with an internal thread 2. The bolt directions of internal thread 1 and internal thread 2 are different. One end of support rod 22 is screwed into support rod 1 21 and the other end is screwed into support rod 3 23.

[0022] Support rod 1 21 and support rod 3 23 are hinged to section steel 2 3 via hinge support 24.

[0023] like Figure 2 As shown, the steel section 1 has several bolt holes 11 evenly arranged, and the two sets of units are connected to the longitudinal support rod 5 through the bolt holes to form a longitudinal support.

[0024] A frame unit is formed by combining four groups of units, and the size of the frame unit is 2440mm×1220mm.

[0025] The working principle is as follows: The retaining plate blocks the soil pressure in the trench. Those skilled in the art will know that the top of the trench is prone to collapse. Therefore, a telescopic support rod 2 must be connected to the top of the two steel sections 2 3. In order to further support the two steel sections 2 3, a telescopic support rod 2 is connected in the middle between them. Since a pipe is to be installed at the bottom of the trench, no telescopic support rod 2 is installed at the bottom between the two steel sections 2 3.

[0026] In practical engineering, outdoor pipeline network projects are an important part of urban infrastructure and industrial site construction. During the construction of outdoor pipeline network projects, trench excavation is required first. The trench slopes are prone to collapse under the action of soil pressure. Therefore, achieving efficient and safe support for the trench is a key issue.

[0027] This utility model adopts a modular support system composed of steel section 1, steel section 2, and adjustable support rod. The feasibility of the support system is verified by establishing modular units, and its safety performance, construction efficiency, and construction cost effect are verified through similar simulation tests and industrial tests.

[0028] This invention utilizes a modular trench support system to enable rapid installation, dismantling, and reuse of the trench support system, effectively improving construction efficiency and reducing construction costs.

[0029] This utility model adopts modular units using slots 4, bolts, hinge supports 24, etc., to realize the rapid assembly of components such as retaining plates, steel plates, and adjustable support rods into small units, and the assembly of small units into complete frame units to form a retaining system. The retaining system can be hoisted into place in one go.

[0030] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and all should be covered by the protection scope of the claims.
