Description

TECHNICAL FIELD

[0001] The utility model relates to prefabricated box culvert joint seepage prevention technical field, especially in prefabricated box culvert joint seepage prevention structure. BACKGROUND

[0002] The prefabricated box culvert joint seepage prevention structure is a construction system for preventing leakage at the joint of the prefabricated box culvert, which is a prefabricated box culvert structure, usually prefabricated in a factory or a prefabrication yard, and then transported to a construction site for splicing and installation.

[0003] A plurality of connecting blocks are fixedly connected to the outside of the box culvert, which is prone to damage to the prefabricated part of the concrete culvert due to bumps, increasing the repair process.

[0004] The existing patent (publication number: CN220538460U) discloses a light aggregate concrete prefabricated box culvert, which comprises at least one prefabricated box culvert installation segment and at least one prefabricated box culvert matching segment, and the end of the prefabricated box culvert installation segment and the prefabricated box culvert matching segment is provided with a joint structure and a connecting structure. This scheme adopts a light aggregate concrete prefabricated box culvert, which has the characteristics of high strength and light weight, is suitable for large segment prefabrication in a factory, and is convenient for hoisting and transportation by conventional equipment. The joint structure and the connecting structure are arranged at the end of the prefabricated box culvert segment to ensure that the side surface of the box culvert segment is as flat as possible, which can prevent damage and deformation caused by bumps during transportation.

[0005] To solve the above problems, the existing patent provides a solution, but the existing prefabricated box culvert joint seepage prevention measures are relatively single, mostly relying on only a single waterproof roll or a simple water stop for seepage prevention. The waterproof roll is prone to aging, wear and tear or local damage during long-term use, resulting in seepage failure. Once damaged, water will quickly seep into a large area, making it difficult to effectively control the seepage path and discharge a small amount of seepage, which can easily cause water accumulation inside the box culvert, affecting the normal use and structural safety of the box culvert.

[0006] Therefore, a prefabricated box culvert joint seepage prevention structure is proposed. UTILITY MODEL CONTENTS
