Description
Technical field
The utility model belongs to pipe gallery technical field of construction, more particularly to a kind of with waterproof, drain function
Underground pipe gallery structure.
Background technology
Pipe gallery is exactly underground urban duct synthesis corridor, i.e., builds a tunnel space in Urban Underground, by electric power,
Communication, the various utilities pipelines such as combustion gas, heat supply, plumbing are integrated in one, and are equipped with special access hole, hoisting port and monitoring system
System implements unified planning, Uniting, unified construction and management, is the important infrastructure and " life for ensureing city operations
Line ".With national fast development, the underground space is made full use of with building underground pipe gallery, to save aboveground space,
Have become irreversible trend.It is long-range that pipe gallery has urban construction as Urban Underground facility artery engineering
Strategic importance.Underground pipe gallery system not only solves Urban Traffic Jam Based, also greatly facilitate electric power, communication, combustion gas,
The maintenance and maintenance of the urban operating mechanisms such as water supply and sewage.In addition, the system also has certain protection against and mitigation of earthquake disasters effect.Such as nineteen ninety-five Japan
During the big earthquakes in Osaka and Kobe, a large amount of house collapses in Kobe city, road are ruined, but the local most intact nothing of underground pipe gallery
Damage, this significantly reduces the difficulty of the disaster relief and reconstruction after shake.Underground pipe gallery is to meeting people's livelihood primary demand and raising
City integrated bearing capacity plays an important role.Pipe gallery construction avoids frequently excavating due to laying and repairing underground utilities
Road and traffic and resident trip are impacted and are interfered, keep the appearance of a street complete and beautiful, reduce the expense that road surface is repeatedly overhauled
With the maintenance cost with utilities pipeline, the durability of the integrality and all kinds of pipelines on road surface is maintained, convenient for applying for various pipelines
If, increase and decrease, repair and daily management.Due to pipeline compact and reasonable arrangement in corridor body, it is effectively utilized the space under road, is saved
Urban land；Due to reducing the roofbolt of road and inspection shaft, the room of various pipelines etc., the graceful landscape in city；Due to
Aerial pipeline enters ground together, reduces the contradiction of overhead line and greening.
It is increasingly ripe that underground pipe gallery builds technology, but pipe gallery build after to destroy the original water system of the soil body flat
Weighing apparatus, causes the water system in the soil body to be pooled together by channel of pipe gallery, when aquifer water-bearing stratum is connected to pipe gallery, to ooze
Water, the disadvantage that leak is principal element just increasingly appear.It is usual with the pipe gallery that open cut prefabrication this construction method is built
It sets up defences water layer and benzene plate using on precast concrete segment upper berth, achievees the effect that waterproof and heat preservation.Pipe gallery waterproof belongs to
Concealed work below town road after completion of road is open to traffic, cannot dig pick road and it is repaired or is repaired easily, because
This, the finished product protection of waterproof layer is also emphasis.If finished product protection is not good at, construction causes destruction and not repairing in time accidentally,
It is easy to form breakthrough, causes the leakage of underground water.
Leakage problem is always the common quality defect for perplexing infrastructure engineering, prevents pipeline and is impregnated now by percolating water for a long time
As it is one of the technical issues of pipe gallery construction must take into consideration to resolve waterproof problem.Waterproof problem is effectively solved to protect
The construction quality for demonstrate,proving integrated pipe canal also can fundamentally reduce security risk, reduce later stage operation maintenance cost, extend and use the longevity
Life.
When building underground pipe gallery, the geological conditions of enrichment water, this treating method of generally use well-points dewatering are encountered.
Handle water the problem of cannot be simply sum up in the point that in this problem of water blockoff, be also required to drain to a certain extent, water dredged
Lead to and effectively manage and be used again, be unlikely to underground water and be largely lost, protects groundwater environment, become present underground and construct
Object handles the main trend of water.This engineering method uses the pipe gallery construction method of open cut prefabrication, when deep-cutting foundation pit, reserves draining
Underdrain is backfilled, and build seugh by laying bricks or stones with water-proof concrete after installing precast concrete segment using pervious concrete,
Discharge and collection that " open roof " is convenient for underground water and ground precipitation are formed, forms ground water circulation in the entire soil body, is reduced
Underground water and impact and damage of the ground precipitation to comprehensive pipe gallery structure, with good economic efficiency and operability can
Play effective waterproof, drainage.
Utility model content
In order to solve above-mentioned technical problem, the utility model can provide a kind of comprehensive with waterproof, the underground of draining
Pipe rack is closed, existing pipe gallery guarded drainage treatment measures can be improved, batch production centralized production is convenient for, it is at low cost,
