Embodiment Construction

[0024] Such as Figure 1-3 As shown, a method for closing the junction of prefabricated concrete comprehensive pipe gallery by extrusion, including the following steps:

[0025] 1) A groove is provided at the joint of two prefabricated concrete integrated pipe galleries, and grooves parallel to it are respectively arranged on both sides of the groove, and a steel member 5 parallel to it is pre-embedded outside the groove;

[0026] 2) Lay the waterstop 1 in the groove, the thickness of the waterstop 1 is 8 mm, the outer edge of the waterstop 1 covers the outside of the groove, and the waterstop airbag 4 in the shape of a cylinder is placed on the In the groove where the waterstop 1 is laid, the volume of the waterstop airbag 4 is larger than the volume of the groove;

[0027] 3) Both sides of the nut fastener 6 are provided with clips 11, the nut fastener 6 is provided with a threaded hole 12, and the nut fastener 6 is clamped on the section steel member 5 through the clip slo...

Abstract

The invention relates to the technical field of municipal engineering, in particular to an extrusion type closing method for a joint of pecast concrete utility tunnels. The technical scheme provided by the invention is that nut fasteners are clamped on profile steel members and are screwed with bolts; by tightening the bolts, a gland compresses a water stop airbag, the water stop airbag expands and compresses water stop belts and further sealing water resistance of the joint of two pecast concrete utility tunnels is realized. The extrusion type closing method for the joint of the pecast concrete utility tunnels, provided by the invention, can realize sealing water resistance and has the advantages of simple structure, high construction speed and low cost.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to an extrusion-type closing method for the joint of a prefabricated concrete comprehensive pipe gallery. Background technique [0002] More than half of the people in our country live in cities, but cities are facing many problems in the field of infrastructure construction, which greatly trouble people's lives. With the emergence of underground comprehensive pipe corridors, there are fewer and fewer urban roads that are repeatedly excavated, and the dense wires above the city are gradually disappearing. Invisible underground risks can be monitored, and cities no longer "look at the sea" when heavy rains come. [0003] The construction of comprehensive pipe gallery is in the ascendant in my country, but in the actual construction process, there are more and more cracks and water leakage at the joints of precast concrete comprehensive pipe gallery, which affects the pr...
