Problems solved by technology
[0003] In many occasions, when steel conduits are used, snap-fit connections are used to facilitate later recycling. However, the fastening method requires threading on the outside of the pipe fittings, which will cause damage to the nozzle of the steel conduits, and the connection between the two steel conduits that are fastened together poor sealing effect

Embodiment
[0026] Such as Figure 1 to Figure 2 As shown, a connecting device for steel conduit pipe fittings includes a position-limiting structure arranged on the side walls of the ends of two steel conduits 1 to be connected, a body one 2 and a body two 3 arranged on the outside of the two steel conduits 1 to be connected, And the fixing piece 4 connecting the first body 2 and the second body 3 as a whole, the first body 2 and the second body 3 are provided with two sets of positioning structures for limiting the position of the limiting structure.
[0027] In a further preferred solution of this embodiment, the limiting structure includes a limiting groove 5 set at the end of the steel conduit 1, the limiting groove 5 is a slope structure and is provided with parallel ends near the end of the steel conduit 1 vertical plane. When the steel conduit 1 is subjected to strong pressure inside the pipe, the vertical surface is used to block the positioning structure, so as to improve the r...

The invention discloses a steel guide pipe connecting device and a mounting method, and belongs to the technical field of pipeline mounting. The steel guide pipe connecting device comprises limiting structures, first bodies and second bodies, wherein the limiting structures are arranged on the side walls of the ends of two to-be-connected steel guide pipes, the first bodies and the second bodies are arranged at the outer sides of the two to-be-connected steel guide pipes, each first body and each second body are connected into a whole through a fixing part, and each first body and each second body are each provided with two positioning structures used for limiting the position of the corresponding limiting structure. each first body and the corresponding second body are connected through the fixing part, then the positions of the steel guide pipes to be connected are limited through limiting grooves formed in the steel guide pipes and elastic positioning parts arranged on the first bodies and the second bodies, and meanwhile the device can be detached only by taking down the fixing part after use is completed; and when the steel guide pipes are used, the steel guide pipes can be effectively and stably installed between the first bodies and the second bodies through reinforcing sleeves. The steel guide pipe connecting device is easy to operate and convenient to install, and greatly reduces the construction difficulty and construction cost.
Description
technical field [0001] The invention relates to the technical field of pipeline installation, in particular to a steel conduit pipe fitting connection device and an installation method. Background technique [0002] Steel conduit is a common pipe fitting, which is not easy to rust during use and can withstand relatively high pressure. It is widely used in the field of foundation grouting reinforcement. The connection of two pipe fittings of steel conduit is usually connected by welding or buckling. Welding is not only time-consuming and laborious, but also cannot be disassembled, which is inconvenient to use. The fastening is connected by using two threaded connectors, one male and one female, and two seals sleeved on the pipe fittings. When in use, the two seals are deformed by the two threaded connectors and tightly fitted on the pipe fittings. . [0003] In many occasions, when steel conduits are used, snap-fit connections are used to facilitate later recycling. Howe...
