Abstract
Description
Technical Field
[0001] The utility model belongs to the field of construction, and in particular relates to an assembled pipeline excavation support device. Background Art
[0002] With the rapid development of urban construction in my country, the development of underground pipelines has also been rapid. The urban underground space is relatively crowded, which often leads to conflicts between urban construction and underground pipelines. The historical underground pipeline data has not been cleared, and new underground pipelines need to be constructed immediately. Therefore, the rapid development of cities inevitably requires a large amount of pipeline construction. Whether laying new pipelines or updating old pipelines, pipeline excavation support devices are one of the essential facilities for pipeline construction and excavation.
[0003] Pipeline excavation supports are temporary retaining structures made of wood or steel to prevent trench wall collapse. The support load is the lateral earth pressure generated by the existing soil and the ground load. The need for additional supports is determined based on factors such as soil quality, groundwater conditions, trench depth, trench width, excavation method, drainage method, and ground load. Generally, supports are required when trenches are dug in poor soil quality, deep, and in a straight trench; or when sandy soils with a high groundwater table are used and open ditch drainage is employed. Utility Model Content
[0004] The purpose of the utility model is to provide an assembled pipeline excavation support device.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:
[0006] An assembled pipeline excavation support device comprises two steel support plates and steel pipes connecting the two steel support plates; the steel support plates are assembledly connected to the steel pipes.
[0007] The steel support plate includes a support plate body and a mounting groove arranged on the support plate body for mounting a steel pipe; bolt holes are correspondingly arranged on the mounting groove and the steel pipe; the corresponding bolt holes are connected by high-strength bolts to connect the steel support plate and the steel pipe.
[0008] There are two bolt holes on each of the mounting slots.
[0009] There are 4 steel pipes.
[0010] A lifting rod is provided on the top of the steel support plate.
[0011] The bottom of the steel is a wedge-shaped end.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] This utility model provides a prefabricated pipe excavation support device with a simple structure, consisting only of prefabricated steel support plates, steel pipes as cross-bracing members, and high-strength bolts. Bolted connections between components make the device fully detachable, facilitating installation, disassembly, and transportation.
[0014] Steel pipes as cross bracing structures are simple, and their lengths can be customized according to the actual project conditions. They are modularly mass-produced by the factory, and can simply and efficiently meet the needs of various pipe excavation projects with different diameters.
[0015] The lifting rod is designed directly on the steel support plate, which facilitates transportation and reduces the number of transport components. The lifting rod can meet the needs of lifting the supporting device when it is brought to the site in the early stage of the project, and can also meet the needs of removing the device from the site or moving it later.
[0016] The utility model reduces the installation and disassembly procedures of the support system, increases the reuse rate of components, improves construction efficiency, and reduces the generation of industrial waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 3 This is a schematic diagram of the steel pipe of the assembled pipeline excavation support device of the utility model. DETAILED DESCRIPTION
[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and the best embodiment.
[0021] Figure 1-3 A prefabricated pipeline excavation support device is shown, comprising two steel support plates 1 and steel pipes 2 connecting the two steel support plates 1; the steel support plates and the steel pipes are prefabricatedly connected.
[0022] The steel support plate 1 includes a support plate body and a mounting groove 12 provided on the support plate body for mounting a steel pipe; bolt holes are correspondingly provided on the mounting groove 12 and the steel pipe; the corresponding bolt holes are connected by high-strength bolts 3 to connect the steel support plate 1 and the steel pipe 2.
[0023] Each of the mounting slots has two bolt holes. There are four steel pipes. A lifting rod 11 is provided on the top of the steel support plate. The bottom of the steel support plate is a wedge-shaped end.
[0024] In one implementation, the prefabricated steel support plate is 2.4m high and 2m wide, with steel pipe cross braces 1.5m long. A prefabricated pipe excavation support system consists of only two prefabricated steel support plates, four steel pipe cross braces, and eight high-strength bolts. Each support frame connects two top formwork supports and six side formwork supports. The prefabricated pipe excavation support system can adjust the length of the steel pipe cross braces to suit actual factory conditions.
[0025] During installation, the prefabricated steel support plate is hoisted and transported to the designated location using the lifting rods on the prefabricated steel support plate. The steel support plate is then installed, followed by the steel pipe cross brace. According to the temporary construction plan, the prefabricated pipe excavation support device components are transported to the designated location. The steel pipe cross brace is inserted into the pre-reserved mounting slots on the support plate and tightened with high-strength bolts. The remaining three steel pipes are then connected, and the other side of the steel support plate is brought in to form a stable base. The device is then installed.
[0026] The purpose of the utility model is to provide an assembled pipeline excavation support device to solve the problems of complex traditional pipeline excavation support structure, low material reuse rate and high construction waste generation.
[0027] The device is connected only with high-strength bolts. We use an assembled structural design, with components connected by steel support plates, steel pipes and high-strength bolts. This is convenient for both initial installation and later disassembly, making the device easy to reuse.
[0028] The technical solution of this application promotes the standardization and industrialization of engineering construction, laying the foundation for improved production efficiency. Furthermore, the use of bolted connections alone can enhance installation speed and precisely control installation quality, improving overall construction efficiency and shortening construction schedules. The steel pipes used as cross braces can be adjusted in length based on actual project requirements, enabling the device to meet the requirements of most pipeline excavation construction projects.
[0029] Due to the prefabricated design requirements, the lifting rod design is directly designed on the steel support plate to facilitate transportation while reducing the number of transport components. The lifting rod can meet the needs of hoisting the support device into the site in the early stage of the project, and can also meet the needs of removing the device from the site or moving it later.
[0030] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
