Abstract
Description
Technical Field
[0001] The utility model belongs to the field of construction engineering, and particularly relates to an assembled pipe jacking shoe. Background Art
[0002] For the traditional open cut and sequential construction method, although the construction method is mature, the risk is small, and the cost of pure civil engineering is relatively low, during the construction period, it is necessary to divert or even close the road traffic, and many underground pipelines under the road may also need to be temporarily relocated or protected, resulting in a very high additional project cost and a great comprehensive impact on society, the surrounding environment, etc.
[0003] When the pipe jacking method is used for construction, it has little impact on ground traffic, can also avoid underground pipelines, has high construction control accuracy, and has little impact on the surrounding environment, so it has obvious advantages. Therefore, it has been widely used in the construction of urban underground pedestrian passageways. In recent years, with the great development of urban rail transit, the pipe jacking method has also begun to be applied to urban rail transit projects, especially in the construction of access channels under main roads. However, the traditional shoe is integrally formed, has a large self-weight, and needs to be replaced as a whole after being worn, resulting in waste of resources. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the defects in the prior art and provide an assembled pipe jacking shoe.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions:
[0006] An assembled pipe jacking shoe includes a plurality of shoe components; both ends of the shoe component are connection ends; connection flanges are arranged at the connection ends; a plurality of the shoe components are connected by bolts to the flanges to form a shoe structure.
[0007] The shoe component includes a main shoe component; there are 4 main shoe components; the main shoe component is L-shaped, and 4 main shoe components are connected to form a shoe structure with a square outer periphery.
[0008] The main shoe component has a length and width of 0.5 m; the thickness is 0.4 m.
[0009] The shoe component further includes a supplementary shoe component; the supplementary shoe component is arranged between two adjacent main shoe components.
[0010] There is one or more supplementary shoe components between two adjacent main shoe components.
[0011] The supplementary shoe component has a length of 0.5 m, a width of 0.2 m, and a thickness of 0.4 m.
[0012] A reinforcing plate is provided between the connecting flange and the backing iron member.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] The prefabricated pipe jacking backing iron of the present utility model can adopt an industrial production mode, with a standardized production process, which can improve production efficiency, realize industrialization of the steel structure assembly process, improve construction quality and work efficiency, promote building industrialization, and reduce construction costs.
[0015] Its size can be changed by adding or reducing components to meet the requirements of different pipe jacking construction environments, that is, it can meet both rectangular pipe jacking construction and circular pipe jacking construction, greatly improving the adaptability of the backing iron in different construction environments. It solves the problem that the traditional pipe jacking backing iron device cannot meet the changing construction requirements.
[0016] The backing iron member of this application is only connected by high-strength bolts. This not only realizes the technology of detachable prefabrication of the backing iron, facilitating disassembly and transportation, but also, since it is a prefabricated splicing member, components can be replaced at any time. It also realizes that in special construction environments, the construction needs can be met by re-designing and replacing components, thus saving design costs, shortening the construction period, and greatly improving construction efficiency.

[0021] In order to enable those skilled in the art of the present technology to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and the best embodiments.
[0022] Figures 1-4 There is shown a prefabricated pipe jacking backing iron, including a plurality of backing iron members; both ends of the backing iron member are connecting ends; a connecting flange 5 is provided at the connecting ends; and a plurality of the backing iron members are connected by bolts 3 to form a backing iron structure.
[0023] The described iron top member includes an iron top main member 1 ( Figure 1 shown); there are 4 of the described iron top main members; the iron top main member is L-shaped, and the 4 iron top main members are connected to form an iron top structure with a square outer periphery ( Figure 3 shown).
[0024] As a preferred form, the length and width of the iron top main member are both 0.5 m; the thickness is 0.4 m, and the weight is about 400 kg.
[0025] The described iron top member further includes an iron top supplement member 2 ( Figure 2 shown); the iron top supplement member is arranged between two adjacent iron top main members. There is one or more iron top supplement members between adjacent iron top main members ( Figure 4 shown). The number of iron top supplement members can be adjusted according to the requirements of pipe jacking construction to adjust the overall size of the assembled iron top.
[0026] As a preferred form, the length of the iron top supplement member is 0.5 m, the width is 0.2 m, the thickness is 0.4 m, and the weight is about 150 kg.
[0027] A reinforcing plate 4 is arranged between the connecting flange 5 and the iron top member (including the iron top main member 1 and the iron top supplement member 2).
[0028] Adopting the implementation scheme of the present utility model, compared with the traditional integral pipe jacking steel that requires a hoisting device to enter the site for configuration, the assembled pipe jacking iron top divides the weight among each member. The mass of a single member is small, and no hoisting device is required to enter the site for configuration, reducing the construction cost. When the assembled pipe jacking iron top enters the site for assembly, from bottom to top, high-strength bolts are aligned with the flange plates between the pipe jacking main members or between the pipe jacking main member and the pipe jacking supplement member, and are tightened by high-strength bolts to be spliced from bottom to top, and finally connected to the pipe jacking machine to ensure the stability and safety of pipe jacking construction.
[0029] In summary, the assembled pipe jacking iron top of the present utility model can adopt an industrial production mode, can carry out a standardized production process, can improve production efficiency, enables the steel bar structure assembly process to achieve industrialization, improves construction quality and work efficiency, promotes building industrialization, and reduces construction costs.
[0030] It can change the size by increasing or decreasing components to meet the requirements of different pipe jacking construction environments, that is, it can meet both rectangular pipe jacking construction and circular pipe jacking construction, greatly improving the adaptability of the iron top in different construction environments. It solves the problem that the traditional pipe jacking iron top device cannot meet the changing construction requirements.
[0031] The top iron component is only connected by high-strength bolts. This not only realizes the technology of prefabricated and detachable top iron, facilitating disassembly and transportation, but also, since it is a prefabricated splicing component, the components can be replaced at any time. It also realizes that in special construction environments, the construction requirements can be met by re-designing and replacing components, thus saving design costs, shortening the construction period, and greatly improving construction efficiency.
[0032] The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, based on the idea of the present utility model, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present utility model.
