[0007] Preferably, the support leg comprises a bracket and a steel sleeve fixedly connected to the bracket, and the other end of the steel sleeve is fixedly connected to the first support assembly or the second support assembly.

[0008] The utility model has the advantages that: by making the support, the support is welded with the steel sleeve, the support can be set according to the specific construction environment and the transport length, the laying track of the whole pipeline is abolished, the automatic range finder installed at the end of the support can also measure the transport distance, and after the installation of the support, the steel pipe is placed on the support, and the steel pipe can be dragged away using a small device. This construction method is simple, fast, low in cost, and can provide reference for similar projects.

[0009] The support is simple and convenient to make, does not need to find a professional factory, is convenient to install, can be reused after construction is completed, can effectively improve work efficiency during construction, greatly reduces safety risks of long-time operation in the pipe jacking, and saves construction cost.

[0010] It should be understood that the foregoing general description and the following detailed description are only exemplary and explanatory and are not restrictive of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0014] Reference Figure 1 A structure diagram of a conveying support for a steel pipe in a steel sleeve of pipe jacking is provided.

[0015] A conveying support for a steel pipe in a steel sleeve of pipe jacking comprises a first support assembly 1 and a second support assembly 2 connected in sequence from head to tail, the first support assembly 1 and the second support assembly 2 are of the same structure, and support legs 3 are arranged on both sides of the bottom of the first support assembly 1 and the second support assembly 2; the first support assembly 1 comprises a first main beam 11 and a second main beam 12, the first main beam 11 and the second main beam 12 are fixedly connected through a cross beam 13, and an upper support 4 is fixedly connected on the first main beam 11, the second main beam 12 and the cross beam 13. The above structural members are connected in the form of welding, and full welding can ensure the strength of the structure.

[0016] Preferably, an automatic range finder 5 is arranged on one side of the outer end of the second support assembly 2. When the steel sleeve is conveyed after the pipe jacking is sequentially welded, the steel pipe conveying can be stopped after the design distance is reached through the induction of the automatic range finder 5, so that the positions of the conveyed steel pipes are neat and consistent, the unified transportation is more convenient, and the steel pipe conveying of different lengths can be realized according to the specific construction environment and the conveying length.

[0017] Preferably, a plurality of roller bearings 6 are fixedly arranged on the upper support 4. Through the arrangement of the roller bearings 6, the steel pipe can be placed on the surface of the roller bearings 6 during the steel pipe conveying process, so that the steel pipe can be placed relatively stably and the risk of falling off is reduced.

[0018] participate Figure 2 , the utility model provides a support leg's structural drawing.

[0019] Preferably, the support leg 3 comprises a bracket 31 and a steel sleeve 32 fixedly connected with the bracket 31, the other end of the steel sleeve 32 is fixedly connected with the first support assembly 1 or the second support assembly 2. The stability of the overall device is improved by the bracket 31, and the steel sleeve 32 is fixedly connected with the first support assembly 1 or the second support assembly 2 in the form of welding.

[0020] In actual use, the overall support is first made off-site, and the support welding position is fully welded. The first support assembly 1 is welded at the bottom of the steel pipe end, and the height is adjusted according to the actual pipe spacing. The second support assembly 2 is welded at the bottom of the top pipe steel sleeve inlet. After the pipes are welded in sequence, the steel sleeve is transported inside. When the automatic distance measuring instrument 5 at the support end head senses that the designed distance is reached, the transportation can be stopped. After the steel pipe is transported to the position, the support is removed after the steel pipe is lifted by a wooden square or other support, and the subsequent construction is carried out.
