Description
Technical field
The present invention relates to a kind of precast concrete culvert pipe, further relates to a kind of prefabricated synthesis containing the precast concrete culvert pipe
Piping lane, further relates to a kind of method for maintaining of prefabricated pipe gallery.
Background technology
As Urban Underground pipe gallery builds the quickening of rhythm, and the active demand that local economy is upgraded to industrialization
The needs built with environmental protection, assembly concrete pipe gallery is thus lifted to unprecedented height, is built single by each
Position, design institute, the extensive concern of unit in charge of construction, assembly concrete pipe gallery will become Urban Underground with its Inherent advantage
The tendency product that pipe gallery is built.
Assembled underground pipe gallery adopts prefabrication tube coupling, the quality of component to be well controlled, but existing
Field is assembled using machinery, and seaming position is waterproof weak spot, and underground pipe gallery is 100 years engineerings, therefore, the research in industry
Mechanism is all using assembled piping lane interface waterproof as important research topic.In order to solve the problem, the scientific worker of China
Hereinafter make great efforts.
Such as Chinese patent CN 105525628A, on April 27 2016 publication date, disclose《A kind of piping lane sealing joint
Device》.Its structure includes being arranged under earth's surface and its middle part is set to the waterproof sealing band of V-arrangement, the V-arrangement of the waterproof sealing band
Two ends are respectively arranged with upper grooves and lower boss, are provided with described groove and withhold module and be fixed in groove
Elastic layering, in the cement components at piping lane interface plane position of the waterproof sealing with both sides pre-buried shaped steel is respectively arranged with,
