Problems solved by technology

Generally, the outer wall of the socket of the steel socket is made of single-slot or double-slot section steel, and a sealing ring is provided in the groove. Although the sealing effect can be achieved, the production cost is relatively high, which affects the cost performance of the entire pipe; and the existing socket There is a groove on the top, and the edge of the top of the groove is easy to scratch the sealing rubber ring during the installation of the sealing rubber ring, thereby reducing the sealing performance and even affecting the sealing performance of the entire pipeline

Embodiment Construction

[0015] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0016] The sealing structure of the concrete pipe socket, its concrete pipe is composed of a socket 1, a socket 4, and a pipe body 3, and the socket and the socket are fixed in the pipe core 2 at both ends of the pipe body. The technical innovation point of the present invention is: an annular groove 5 is formed radially and coaxially on the outer wall of the concrete pipe socket, and a sealing rubber ring 6 is embedded in the annular groove. When two concrete pipes are connected, the sealing rubber ring can effectively seal the gap between the socket and the socket (see figure 2 ).

[0017] The cross-sectional shape of the annular groove is semicircular, elliptical or square, and it is semicircular as shown in the drawings of this embodim...

Abstract

The invention relates to a sealing structure in a concrete reinforced pipe bell and faucet. The concrete reinforced pipe consists of a bell mouth, a faucet and a pipe; the bell mouth and the faucet are fixedly arranged in a pipe core at the two ends of the pipe; wherein, an outer wall of the concrete reinforced pipe faucet is coaxially provided with a ring socket along the radial direction. The invention has the advantages of simple integral structure, scientific and reasonable design, low construction cost and simple technique; the ring socket structure can increase the sealing property between concrete reinforced pipes and raise the integral sealing level of concrete reinforced pipes.

Description

technical field [0001] The invention relates to concrete pipes, in particular to a sealing structure for concrete pipe sockets. Background technique [0002] In the prior art, steel sockets are mostly used for large-diameter concrete pipes. The advantages are mainly reflected in: 1. The steel sockets have high strength and strong anti-collision ability; 2. Easy installation and simple construction operation; 3. Relatively impermeable powerful. Generally, the outer wall of the socket of the steel socket is made of single-slot or double-slot section steel, and a sealing ring is provided in the groove. Although the sealing effect can be achieved, the production cost is relatively high, which affects the cost performance of the entire pipe; and the existing socket There is a groove on the top, and the edge of the top of the groove is easy to scratch the sealing rubber ring during the installation of the sealing rubber ring, thereby reducing the sealing performance and even affe...
