[0001] The utility model relates to the field of municipal engineering construction, in particular to a waterproof coiled material protection device for the inner corner under the pipe gallery. Background Technique

[0002] At present, during the construction of urban roads, the problem of water leakage of the waterproof coiled material at the inner corner of multi-warehouse structures such as comprehensive pipe galleries often occurs. The traditional waterproof coiled material protection measures are as follows: Before pouring the bottom slab of the pipe gallery, a waterproof protection brick wall is built, and the outer waterproof coiled material is turned up to the top of the waterproof protection brick wall. When the formwork on the outside of the side wall of the pipe gallery is supported, the steel pipe back ribs behind the formwork generally directly press on the waterproof coiled material above the waterproof protection brick wall, which is easy to damage the waterproof coiled material, thereby increasing the probability of water leakage of the structure. In addition to the above, when the outer waterproof coiled material is turned up to the top of the waterproof protection brick wall, a 90° fold is required, and the folded part is easily wrinkled and damaged, not easy to fit, and easy to deviate.
