Abstract

The invention relates to a connecting structure for a prefabricated cable well and cable duct cast-in-place structure and a construction method thereof. The connecting structure comprises rebar connectors, duct reinforcing bars, cable sleeves and cable ducts. One end of each rebar connector is connected with an L-shaped rebar embedded in a well wall, and the other end of each rebar is connected with one duct reinforcing bar. The cable ducts are nested in the cable sleeves disposed inside the well wall, respectively. A form recess outside the well wall and the ducts are in concrete encapsulation fit. The connecting structure and the construction method thereof have the advantages that the prefabricated cable well and concrete encapsulation can be integrated, the water proofing requirement is met through the use of the cable sleeves, and the problem of possible differential settlement can be solved through the use of the form recess reserved in a prefabricated well.

Description

technical field [0001] The invention relates to a connection structure between a prefabricated cable well and a cast-in-place structure for cable pipes and a construction method thereof. Background technique [0002] The prefabricated inspection well has the advantages of good integrity, good durability, and increased construction speed. However, in the field of electric power / communication engineering, the connection between the prefabricated inspection well and the cast-in-place concrete encapsulation of the pipes has become the basis for construction quality control. Weak links, because the existence of such construction gaps reduces the integrity of the power and telecommunication systems, there may be cracks and water leakage between the inspection well wall and the concrete envelope due to factors such as uneven settlement and the flexibility of the cast-in-place concrete structure. Chinese patent CN202131613 discloses a lined prefabricated reinforced concrete inspecti...
