Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention is further described, and present way is to adopt the construction of changing pipe method, and in fact this way is effective, and concrete way is as follows:

[0012] (1) Preparations before construction and restoration: 1 excavator, 2 cranes, 1 pumping equipment, 1 replacement cement pipe, 2 rubber rings, plus some small supporting tools.

[0013] (2) In order to clearly explain the situation, we code the replaced cement pipe as No. 2 (replacing the damaged water pipe), and the cement pipe with the socket facing the No. 2 pipe is coded as No. 1, and the socket is facing the No. 2 pipe. The cement pipe is coded as No. 3.

[0014] (3) The excavator digs out the covering soil of No. 1~3 pipes, and manually cleans the remaining soil in the pipe ditch.

[0015] (4) Lift the damaged cement pipe in the middle by the crane, align the socket of No. 2 pipe with the socket of No. 1 pipe (the socket of No. 1 p...

Abstract

A method for applying a flexible connector to leakage repair and butt joint of a prestressed cement pipe includes the steps of preparation before construction, pipeline excavation and replacing pipeline installation. The method has the advantages of shortening water cut-off time, improving social and economical benefits, guaranteeing construction quality, lowering repair rate and the like.

Description

technical field [0001] The invention relates to the field of pipeline construction, in particular to an application method of a flexible interface in leak repair and collision of small-diameter prestressed cement pipes. Background technique [0002] Cement pipes are widely used because of their economy. Due to various reasons, the bursting of cement pipes is also relatively common, so some experience and methods have been accumulated in repairing cement pipes. In the past, we generally adopted the method of adding a hoop to the damaged part, and then filling it. That is to check the diameter of the water pipe, fix the finished hoop at the damaged part by screw fastening or welding, drive it in with hemp silk, and then use the three-in-one interface construction method of gypsum powder, calcium chloride, and silicate. The hoop is made of 10 mm steel plate, the hoop diameter is 50~60 mm larger than the pipe diameter, the length is between 600~800 mm, and it is divided into u...
