Description

TECHNICAL FIELD

[0001] The utility model relates to the field of comprehensive pipe gallery construction auxiliary equipment, concretely relates to an underground comprehensive pipe gallery ring type waterstop fixing device. BACKGROUND

[0002] The underground comprehensive pipe gallery is a structure and accessory facility arranged below the ground of a city and used for accommodating two or more public facility pipelines or professional pipelines. The public facility pipelines include power, communication (including monitoring lines), radio and television, water supply, drainage, heat, gas, fire-fighting pipeline, traffic signal, emergency optical cable, etc. The accessory facility includes drainage, ventilation, lighting, electrical, communication, fire-fighting, safety monitoring system and monitoring management room for maintaining the normal operation of the pipe gallery.

[0003] The underground comprehensive pipe gallery is mostly made of anti-permeation concrete. The key to waterproofing is the deformation joint waterproofing, which is mostly carried out by using a waterstop. At present, the fixing of the waterstop of the open-cut pipe gallery generally uses a penetrating rubber waterstop to be fixed on a formwork or structural reinforcement, or directly uses the formwork or wooden bar to clamp and fix the rubber waterstop. The first fixing method damages the rubber waterstop, seriously affects the waterstop effect of the waterstop and damages the waterproof function of the underground comprehensive pipe gallery. The second fixing method has poor fixing effect. Moreover, the formwork or structural reinforcement can only be clamped and fixed outside the concrete chamber to be poured, and the clamping and fixing effect is poor. When the concrete is poured or vibrated, the position is easily deviated, so that the rubber waterstop cannot be positioned at the middle of the deformation joint after the concrete is poured, and the position deviation of the rubber waterstop causes the leakage of the slurry at the position, affecting the waterproof function.

[0032] The number of the first sleeves 3 is equal to the number of the first supporting rods 2, and the first sleeves 3 are arranged one by one corresponding to the first supporting rods 2. The first sleeves 3 are detachably sleeved on the first ends of the first supporting rods 2.

[0033] In an embodiment, the ring type water stop 7 is sleeved on the outer sides of all the first sleeves 3, and the ring type water stop 7 is pried open from the inner side by the first sleeves 3, thereby playing a role of fixing the ring type water stop 7 and preventing the position from deviating during pouring and vibrating of concrete. The ring type water stop 7 can be in direct contact with the first sleeves 3.

[0034] In another embodiment, in order to facilitate the installation of the ring type water stop 7, the width of the ring type water stop 7 is greater than the distance between the two first sleeves 3, i.e. the ring type water stop 7 is relatively loose when sleeved on all the first sleeves 3. In order to prevent the ring type water stop 7 from being separated from the first sleeves 3, the underground comprehensive pipe gallery ring type water stop fixing device of the embodiment further comprises a plurality of second supporting rods 4 and a plurality of second sleeves 5.
