Technical Field

The utility model relates to a utility tunnel engineering field especially relates to a utility tunnel hole for hoist block structure.

Background

Utility tunnel refers to builds a tunnel space that collects electric power, communication, gas, heat supply, engineering such as plumbing as an organic whole in city underground, important infrastructure and lifeline that ensure city operation, current utility tunnel is mostly formed by the concatenation of prefabricated tube coupling, however because the weight of prefabricated tube coupling is great, it is not hard up easily to appear in its hole for hoist department, and constructor only often packs cement mortar in hole for hoist department when carrying out prefabricated tube coupling outer wall waterproof construction, in case the waterproof system of this department is invalid, the percolating water is very easily inside getting into the tube coupling from this department.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above object, the utility model adopts the following technical scheme: a comprehensive pipe gallery hoisting hole plugging structure comprises pipe joints, a bidirectional reinforcing mesh, a hoisting assembly, reinforcing rings, a polymer cement mortar layer, a sealing adhesive layer, a waterproof structure layer and an additional waterproof layer; the pipe joints are of a prefabricated waterproof concrete structure, and bidirectional reinforcing steel bar meshes are arranged in the pipe joints; the hoisting assembly comprises a steel pipe, a steel bottom plate, a steel hoisting ring and a steel bar hook; the steel pipe is embedded in the pipe joint, the steel bar hooks are welded on two sides of the bidirectional steel bar mesh on the outer wall of the steel pipe, and the steel bar hooks on the two sides of the bidirectional steel bar mesh are staggered with each other; a reinforcing bar ring is welded between the reinforcing bar hook and the bidirectional reinforcing bar net; the bottom of the steel pipe is welded with a steel bottom plate, and the middle part of the steel bottom plate is also welded with a steel hanging ring; after the pipe joints are hoisted, a polymer cement mortar layer is filled in the steel pipe, and a sealing adhesive layer is sprayed at the outer end of the steel pipe; the outer wall of the pipe joint is also laid with a waterproof structure layer which sequentially comprises a high-molecular self-adhesive waterproof coil material layer, a petroleum asphalt felt isolating layer and a fine aggregate concrete protective layer from inside to outside; an additional waterproof layer is further laid between the outer wall of the pipe joint and the high-molecular self-adhesive waterproof coil material layer at the position of the steel pipe, and the distance between the outer end of the additional waterproof layer and the outer wall of the steel pipe is 100-200 mm.

Preferably, the outer end of the polymer cement mortar layer is provided with an angle joint on the inner wall of the steel pipe.

Preferably, the outer end of the steel bottom plate extends 50-100mm beyond the outer wall of the steel pipe.

The utility model has the advantages that: the comprehensive pipe gallery lifting hole plugging structure is characterized in that a sealing adhesive layer and an additional waterproof layer are arranged at the outer end of a steel pipe, and the sealing performance of the sealing adhesive layer is improved by reserving an angle seam at the outer end of a polymer cement mortar layer, so that the waterproof effect at the lifting hole is greatly improved; the steel bar hooks are welded on two sides of the two-way steel bar mesh on the outer wall of the steel pipe, and the steel bar rings are welded between the steel bar hooks and the two-way steel bar mesh, so that the connection performance of the steel pipe and the pipe joints is enhanced, the bearing capacity of the steel hanging ring is improved, and the possibility of looseness of the hoisting hole is reduced.
