Problems solved by technology

[0004] However, the spare pipe for PCCP engineering accident in this patent is designed as a steel telescopic pipe. Not only is the structure of the device complex, the cost is high, and the installation weight is heavy. Moreover, the whole device is placed in the soil and is easily corroded by groundwater, causing new damage.

Embodiment 1

[0045] Such as Figure 1-Figure 4 As shown, the PCCP pipeline accident treatment device includes an accident treatment pipe 1, the accident treatment pipe 1 has the same structure as the conventional PCCP pipe, the length of the accident treatment pipe 1 is shorter than the conventional PCCP pipe, and the two ends of the accident treatment pipe 1 length are A socket, and one end is a conventional socket 3 that matches the socket at one end of a conventional PCCP pipe, and the other end is a telescoping end socket 2 that matches the telescoping socket;

[0046] The telescopic device includes a telescopic tube 4 with an inverted T-shaped axial section, and both ends of the telescopic tube 4 are sockets, and the two sockets can respectively extend into the telescoping end socket 2 of the accident handling tube 1 and the adjacent conventional socket. In the conventional socket 3 of the PCCP pipe, one or two rubber rings 5 ​​are set on the outer pipe walls at both ends of the teles...

Embodiment 2

[0062] Different from Embodiment 1, the protruding part on the outer wall of the telescopic tube is discontinuous and several parts on the same circumferential line, and the several parts correspond to the flange chucks on the outer wall of the adjacent conventional PCCP pipe. Easy bolt and nut connection for easy movement of telescoping tubes. The rest are exactly the same as those in the embodiment, and will not be repeated here.

Abstract

The invention discloses a PCCP accident treating device. The PCCP accident treating device comprises an accident treating pipe. The structure of the accident treatment pipe is the same as that of a conventional PCCP, and the length of the accident treatment pipe is smaller than that of the conventional PCCP. Sockets are formed in the two ends of the accident treating pipe in the length direction respectively, one socket is a conventional socket matched with an insertion opening in one end of the conventional PCCP, and the other socket is a stretcher end socket matched with an insertion opening of a stretcher. The invention further discloses an installation method for the PCCP accident treating device. When the accident that the PCCP needs to be replaced is treated, rapid and simple treatment can be carried out by means of the PCCP accident treating device and the installation method in the technical scheme.

Description

technical field [0001] The invention relates to a pipeline technology, in particular to a PCCP pipeline accident treatment device and an installation method thereof. Background technique [0002] At present, PCCP pipes have been widely used at home and abroad. Its structure is to pour concrete on the inside and outside of the steel cylinder, then wind high-strength prestressed steel wires on the outer concrete layer, and spray the protective layer. It has the advantages of low investment, convenient installation, and use. The feature of long service life, due to the use of socket joints, makes its construction speed very fast, but in use, once the prestressed steel wire breaks, the prestressed steel wire of the whole pipe will lose its function and cause a pipe burst, and because of the use of sockets , the usual accident handling method is to replace a section of pipe, and at the same time, according to the calculation of the deflection angle, use several lifting equipment ...
