AI Technical Summary
Existing technologies make it difficult to safely drill holes and connect pipes while they are wet, which can easily lead to pipe rupture, affecting water supply stability and increasing socio-economic losses.
Using clamps and perforation components, a protective layer is formed by grouting concrete mortar. Drilling is carried out without stopping water flow using gate valves and perforation machines to prevent prestress failure. Modularly designed clamp bodies and inner rings are used for rapid assembly and reinforcement.
This method enables the PCCP pipeline to be opened without interrupting water supply, avoiding pipeline rupture, improving construction safety and water supply stability, reducing water pollution and economic losses, and shortening the construction cycle.

Abstract
Claims
1. A PCCP pipe non-stop water supply opening connection device, comprising a PCCP pipe (5), characterized in that: The PCCP pipe (5) is fitted with a clamp, and the outside of the clamp is also connected to an opening assembly for making a non-stop water flow opening for the PCCP pipe (5); The clamp is filled with concrete mortar, and after the concrete mortar solidifies, it forms a protective layer. The protective layer is used to prevent the prestress from failing and cracking when the PCCP pipe (5) is opened. The opening assembly specifically includes a flange (8) connected to a clamp, and a gate valve (3) opening connected to one end of the flange (8), and a hole opener (4) connected to the other end of the gate valve (3). The hole punch (4) is used to punch holes in the protective layer and the PCCP pipe (5) without interrupting water flow through the gate valve (3). The gate valve (3) is used to close the hole and connect the branch pipe after the hole punch (4) has drilled the hole.
2. The PCCP pipe hot tapping connection device of claim 1, wherein, The clamp component specifically includes a clamp body (1), and there are two clamp bodies (1), and the two clamp bodies (1) are mirror-symmetrically spliced together as a whole; Both ends of a single clamp body (1) are fitted with an inner ring (6), and the inner ring (6) and the clamp body (1) are joined at the eaves to form a grouting cavity (7). The two clamp bodies (1) are joined together and have grouting holes (2), and concrete mortar is injected into the grouting molding cavity (7) through the grouting holes (2).
3. The PCCP pipe hot tapping connection device of claim 2, wherein, A connecting hole (10) is provided on the side of any clamp body (1), and the flange (8) is connected to the connecting hole (10).
4. The PCCP pipe hot tapping connection device of claim 2, wherein, Two clamp bodies (1) and the inner ring (6) are provided with fastening ears (9) on the outer side of their close end faces, and the corresponding fastening ears (9) are connected by fastening bolts.
5. The PCCP pipe hot tapping connection device of claim 4, wherein, The number of fastening ears (9) is several.
6. The PCCP pipe hot tapping connection device of claim 2, wherein, The diameter of the two inner loops (6) after splicing matches the diameter of the PCCP pipe (5), and the diameter of the two clamp bodies (1) after splicing is greater than the diameter of the two inner loops (6) after splicing.
