technical field

The utility model relates to the technical field of site protection construction engineering, in particular to a counterforce support for pipe jacking construction.

Background technique

The site protection exhibition project needs to install steel structure pipe jacking in the concrete jacking pipe. At present, the on-site pipe jacking construction uses hydraulic jacks to provide a large counter force to push the steel structure pipe jacking into the concrete jacking pipe. However, hydraulic jacks must use pump stations and steel strands as traction equipment, which has high investment costs, and due to their slow moving speed, the construction efficiency is very low when performing steel structure pipe jacking.

Utility model content

The purpose of the utility model is to provide a pipe jacking construction reaction force bracket, which can reduce the equipment cost of pipe jacking construction and improve work efficiency.

For realizing above-mentioned object, the technical scheme that the utility model adopts is:

A pipe jacking construction reaction force support, including a support mechanism and a traction mechanism, the support mechanism includes a pipe jacking hoop, a central support plate and a transverse bracket, and the pipe jacking hoop is arranged at the end of a concrete pipe jacking, The central support plate is located on one side of the concrete jacking pipe and is facing the end face of the concrete pipe jacking. The horizontal support connects the hoop of the pipe jacking and the central support plate. One end of the horizontal support is fixed on the hoop, and the horizontal support the other end of which is fixed on the center support plate; the traction mechanism includes a winch, a traction rope and a guide pulley, the guide pulley is arranged on the center support plate, and the guide pulley is directly opposite to the center of the concrete jacking pipe. The traction rope goes around the guide pulley to connect the winch and the steel structure jacking pipe.

The transverse support includes three bases and three struts, the three bases are evenly arranged on the hoop of the jacking pipe along the circumferential direction, one end of the three struts is respectively set on the three bases, and the three struts The other ends of the rods are jointly arranged in the middle of the center support plate.

The pipe jacking hoop includes two semicircular steel plates, and the two semicircular steel plates are fastened and connected by bolts.

The traction rope is a steel wire rope.

The base and the struts are made of strip steel.

The utility model uses the horizontal bracket to fix the central support plate, and fixes the horizontal bracket on the concrete jacking pipe through the jacking hoop, so that the reaction force bracket can be recycled and greatly reduces the construction cost; the utility model uses the hoist as the traction device, Not only reduces equipment input cost, but also effectively improves work efficiency.

Further, the utility model utilizes three bases and three struts to make the reaction force bracket into a triangular cone shape, which enhances the stability of the bracket structure.

Detailed ways

As shown in Figure 1 and Figure 2, a pipe jacking construction reaction force support described in the utility model includes a support mechanism and a traction mechanism. The pipe hoop 3 is composed of two semicircular steel plates with a thickness of 10mm. The two semicircular steel plates are installed at the end of the concrete jacking pipe 1, and the two ends are fastened and connected by bolts 11. The central support plate 5 is located on one side of the concrete jacking pipe 1 and faces the end face of the concrete jacking pipe 1 , and the central support plate 5 is fixed on the pipe jacking hoop 3 through the transverse bracket 4 . The horizontal bracket 4 of the utility model includes three bases 7 and three struts 8, the three bases 7 are uniformly welded on the hoop 3 of the jacking pipe along the circumferential direction, and one ends of the three struts 8 are respectively welded on the three bases 7, The other ends of the three braces 8 are jointly welded to the middle of the center brace 5 to form a triangular conical bracket, which effectively improves the stability of the counterforce bracket. The base 7 and the strut 8 of the utility model are all made of bar-shaped steel, and the materials are common and cheap.

The traction mechanism of the utility model includes a hoist 10, a traction rope 9 and a guide pulley 6, the guide pulley 6 is fixed on the center support plate 5, and is facing the center of the concrete jacking pipe 1, and the traction rope 9 bypasses the guide pulley 6 to connect the hoist 10 and steel structure jacking pipe 2, traction rope 9 of the present utility model adopts steel wire rope. The working principle of the utility model is: after the construction of the concrete pipe jacking 1 is completed, the end of the pipe is leaked out of the soil layer of the relic area by about 0.5m, and as the fixed position of the pipe jacking hoop 3, the pipe jacking hoop 3 is tightened by bolts 11 On the concrete jacking pipe 1, the central support plate 5 connected by the transverse bracket 4 faces the end face of the concrete jacking pipe 1, and the guide pulley 6 is fixed on the central support plate 5 so that it faces the center of the concrete jacking pipe 1, and the The traction rope 9 connected to the winch 10 bypasses the guide pulley 6 to connect the steel structure jacking pipe 2 at the other end of the concrete jacking pipe 1 , and the steel structure jacking pipe 2 is gradually pulled into the concrete jacking pipe 1 by the operation of the hoist 10 .
