Problems solved by technology

[0007] However, none of the above reference documents discloses the use of foam boards to form the flow path, nor does it disclose the use of hollow steel plates, so the specific construction methods are completely different from those of this application.

Embodiment 1

[0032] The main drainage pipe of the infrastructure of a certain community, the drainage pipes leading from each residential building need to be connected to the main drainage pipe. Junction pipes must be used at the junction. If the traditional joint pipe is used, the engineering quantity is large, the structure is complex, the size requirements are strict, and the size of the joint pipe cannot be selected according to the actual situation on site.

[0033] Therefore, the special-shaped joint pipe described in this application is adopted. as attached figure 1 Shown, a special-shaped joint pipe, including steel plate, foam board and strong glue. The steel plate is made of 45# steel with an average thickness of 5mm. The foam board is made of polyurethane with an average thickness of 20mm.

[0034] The steel plate and the foam board are bonded by strong glue, enclosing a cavity in the form of a basic rectangle to form a hollow part. The hollow part is roughly a hollow rectan...

Embodiment 2

[0043] The water guide channel of a certain tunnel guides the overflow of various parts into the drainage channel to discharge, so as to ensure the safety of the tunnel lining. The special-shaped joint pipes used include steel plates, foam boards and strong adhesive glue. The steel plate is made of stainless steel with an average thickness of 10mm, the foam board is made of polyurethane with an average thickness of 25mm, and the strong adhesive glue forms the bonding layer, and the inorganic super glue is used.

[0044] The steel plate and the foam board are bonded by strong glue, enclosing a cavity in a substantially circular form to form a hollow part. The hollow part is approximately 18mm in diameter and 220mm in height. The outer side of the hollow part is steel plate, and the inner side is foam board. The upper end of the steel plate is provided with lifting lugs, the lifting lugs are provided with hanging earrings, and the hanging earrings are basically arched (not sho...

Abstract

The invention provides a special-shaped joint pipe. The special-shaped joint pipe comprises a steel plate, a foam plate and strong adhesive, wherein the steel plate comprises a hollow part; the foam plate is fixed on the steel plate through the strong adhesive; and the steel plate comprises a lifting lug. According to the special-shaped joint pipe, a convex joint is formed by combining a hollow steel plate pile with the foam plate, so that a turbulent flow path is increased compared with an arc-shaped joint of a circular joint pipe, and therefore, anti-permeability is strengthened. The foam plate is used for replacing steel, so that manufacturing cost is reduced; meanwhile, weight of the whole joint pipe is reduced, so that perpendicularity can be controlled very well in a lowering process; and a contact area between the hollow steel plate and concrete is reduced compared with that of a circular locking hole pipe, so that holding force, on the joint pipe, of the concrete is reduced, difficulty in a pulling process is reduced, construction speed of a ground wall is increased to a certain extent, and a construction period is shortened.

Description

technical field [0001] The invention relates to a pipe, in particular to a special-shaped joint pipe used in the field of underground continuous wall water stop. Background technique [0002] As an integral part of the underground main structure, the underground diaphragm wall must be permanent and durable, with no seepage, no leakage, and balanced stress in the whole structure. Among them, the quality of anti-seepage effect is directly related to the quality of the joint, and the form of the joint is an important means to improve the anti-seepage effect. As the connection structure between the unit groove sections of the underground diaphragm wall, the joint is the core link of the underground diaphragm wall system. Joint form is the core technology of underground diaphragm wall construction technology. [0003] At present, the joint pipes are mostly in the form of circular joint pipes. During the construction process, the turbulence path of the circular joint pipes is not...
