Description

Technical Field

[0001] This utility model relates to the field of pipe jacking technology, and in particular to a reinforced fiberglass composite pipe jacking system. Background Technology

[0002] In municipal engineering and underground pipeline laying, pipe jacking technology, as a trenchless construction method, is widely used due to its minimal impact on surface traffic and the environment. The core component of this technology is the jacking pipe, which must withstand enormous jacking forces and complex soil pressures during construction, thus requiring extremely high strength, rigidity, and durability. However, existing reinforced fiberglass composite jacking pipes still suffer from low overall strength and are easily damaged by the forces exerted by the jacking structure.

[0003] Therefore, it is essential to invent a reinforced fiberglass composite jacking pipe. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a reinforced fiberglass composite jacking pipe, solving the issue that existing reinforced fiberglass composite jacking pipes still suffer from low overall strength and are easily damaged by the force of the jacking structure. A reinforced fiberglass composite jacking pipe includes a reinforcing outer cladding layer, a fiberglass inner liner, a positioning and protective ring, a connecting threaded hole, a suspension structure, and a pressure-bearing top ring. The positioning and protective ring is fixedly installed on the outer side of one end of the fiberglass inner liner, and the reinforcing outer cladding layer is slidably installed on the outer side of the fiberglass inner liner and fixed therein. The connecting threaded hole is located on the outer side of the reinforcing outer cladding layer, and the suspension structure is threaded into the connecting threaded hole. The pressure-bearing top ring is fixedly installed on one end of the reinforcing outer cladding layer.

[0005] The length of the fiberglass inner liner is the same as that of the reinforcing outer layer, and the lengths of the fiberglass inner liner and the reinforcing outer layer are offset from each other. One end protrudes 20 cm from the reinforcing outer layer, and the other end is recessed 20 cm into the reinforcing outer layer. The positioning protective ring is 20 cm away from one end of the fiberglass inner liner and contacts the end of the reinforcing outer layer that is not fitted with the pressure-bearing top ring.

[0006] The reinforced outer layer includes a concrete pipe, a fiberglass reinforced frame, and threaded mounting holes, with the fiberglass reinforced frame being filled inside the concrete pipe. The threaded mounting holes are located at one end of the concrete pipe that does not contact the positioning protective ring.

[0007] The pressure-bearing top ring includes a pressure-bearing ring, a leveling countersunk hole, and a connecting bolt. The pressure-bearing ring is fixedly installed at one end of the reinforcing outer layer, and the leveling countersunk hole is opened inside the pressure-bearing ring. The connecting bolt connects the reinforcing outer layer and the pressure-bearing top ring together.

[0008] The reinforced concrete pipe inside the outer cladding is a single concrete pipe, which is cast using a mold. During casting, a fiberglass reinforcing frame is installed inside the concrete pipe. Several threaded holes are provided for connecting bolts to be driven into the pipe.

[0009] The pressure-bearing top ring is made of a steel metal ring, and the thickness of the pressure-bearing top ring is exactly the same as that of the reinforcing outer layer. The pressure-bearing top ring hides the connecting bolts through the leveling countersunk hole, forming a flat surface.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The reinforced outer layer of this utility model provides the main compressive strength and overall rigidity for the jacking pipe. The internal concrete pipe and the fiberglass reinforced frame jointly bear the jacking thrust and the soil load. At the same time, it serves as a functional base, through which the suspension structure and the pressure-bearing top ring are installed, and the internal fiberglass liner is protected from damage. It also works with the positioning and protective ring to achieve the misalignment connection of the pipe sections.

[0011] The pressure-bearing top ring of this utility model can serve as the direct force-bearing surface of the jack during jacking construction. Through its internal pressure ring, the huge jacking force is evenly transmitted to the end face of the entire reinforced outer layer, preventing local crushing of the concrete. By firmly connecting the leveling countersunk hole and the installation threaded hole at the end of the reinforced outer layer with the connecting bolt, a flat and solid pressure-bearing plane is formed, ensuring the efficient and stable transmission of the jacking force and protecting the end of the pipe body.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] As attached Figure 1 To be continued Figure 3 As shown.

[0018] This utility model provides a reinforced fiberglass composite jacking pipe, comprising a reinforcing outer cladding layer 1, a fiberglass inner lining pipe 2, a positioning protective ring 3, a connecting threaded hole 4, a suspension structure 5, and a pressure-bearing top ring 6. The positioning protective ring 3 is fixedly installed on the outer side of one end of the fiberglass inner lining pipe 2, and the reinforcing outer cladding layer 1 is slidably installed on the outer side of the fiberglass inner lining pipe 2 and fixed thereto. The connecting threaded hole 4 is located on the outer side of the reinforcing outer cladding layer 1, and the suspension structure 5 is threadedly engaged within the connecting threaded hole 4. The pressure-bearing top ring 6 is fixedly installed on one end of the reinforcing outer cladding layer 1.

[0019] The length of the fiberglass inner liner tube 2 is the same as that of the reinforcing outer layer 1, and the lengths of the fiberglass inner liner tube 2 and the reinforcing outer layer 1 are offset from each other. One end protrudes 120 cm from the reinforcing outer layer, and the other end is recessed 120 cm into the reinforcing outer layer. The positioning protective ring 3 is 20 cm away from one end of the fiberglass inner liner tube 2 and contacts one end of the reinforcing outer layer 1 that is not fitted with the pressure-bearing top ring 6.

[0020] The reinforced outer layer 1 includes a concrete pipe 11, a fiberglass reinforced frame 12, and a mounting threaded hole 13. The fiberglass reinforced frame 12 is filled inside the concrete pipe 11, and the mounting threaded hole 13 is opened at one end of the concrete pipe 11 that does not contact the positioning protective ring 3.

[0021] The pressure-bearing top ring 6 includes a pressure-bearing ring 61, a leveling countersunk hole 62, and a connecting bolt 63. The pressure-bearing ring 61 is fixedly installed at one end of the reinforcing outer layer 1, and the leveling countersunk hole 62 is opened inside the pressure-bearing ring 61. The connecting bolt 63 connects the reinforcing outer layer 1 and the pressure-bearing top ring 6 together.

[0022] The concrete pipe 11 inside the reinforced outer layer 1 is a single concrete pipe, and the concrete pipe 11 is cast by a mold. The concrete pipe 11 is reinforced with a fiberglass reinforcing frame 12 inside during casting. The installation threaded holes 13 are of several types, which can allow the connecting bolts 63 to be driven into them.

[0023] The pressure-bearing top ring 6 is made of a steel metal ring, and the thickness of the pressure-bearing top ring 6 is exactly the same as that of the reinforcing outer layer 1. The pressure-bearing top ring 6 hides the connecting bolt 63 through the leveling countersunk hole 62, forming a plane.

[0024] The working principle of the reinforced fiberglass composite jacking pipe described in this utility model is to achieve efficient force transmission and reliable connection of pipe sections through the composite structure. During jacking construction, the thrust of the jacks acts directly on the pressure-bearing top ring 6 of the first pipe section, and the jacking force is evenly transmitted to the end of the reinforced outer cladding 1 through its pressure ring 61 and connecting bolts 63. The reinforced outer cladding 1, as the main load-bearing structure, is jointly borne by the internal concrete pipe 11 and fiberglass reinforced frame 12 to withstand the axial thrust and ground load, ensuring the compressive strength and overall stability of the pipe body during the jacking process.

[0025] The pipe section connection employs a unique staggered design. The protruding end of the fiberglass inner liner 2 of one pipe section is connected to the end of the reinforcing outer cladding 1 of the adjacent pipe through a positioning protective ring 3, achieving a socket joint that ensures both connection sealing and improved overall rigidity. During construction, the suspension structure 5 is connected to the reinforcing outer cladding 1 via threaded holes 4, providing hoisting support. Ultimately, a composite pipe gallery system is formed, where the reinforcing outer cladding 1 bears the external load, and the fiberglass inner liner 2 ensures a smooth, corrosion-resistant inner wall.

[0026] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
