Description
Technical field
The present invention relates to underground engineering water control technique field, specially a kind of packaged type tunnel waterproofing device and side
Method.
Background technique
Underground engineering (such as underground railway, vcehicular tunnel and mine tunnel engineering) can often encounter molten in process of construction
The hydrology such as hole, fractured zones or sandy gravel stratum and engineering geological condition defective sector, not only supporting difficulty is larger in these locations, and
And the phenomenon that being frequently accompanied by country rock water burst, water burst need to be controlled in such a way that slip casting forms water seal curtain.
Complicated hydrogeological conditions region is limited to existing surveying method, goes in engineering construction toward to actual water
Literary geological conditions exist recognize it is insufficient and not in time the phenomenon that, cause site operation not in time effectively to the implementation of water outlet position
Grouting for water blocking.After tunnel unit time water yield is more than the drainability of pumping equipment, if processing is not in time or improper measures,
It is light then easily lead to well lane engineering flooded, equipment damage, influence engineering project progress and to cause any property loss；It is heavy then can generate great
Personnel casualty accidents.
By consulting related literatures discovery, the method for control water burst is commonly used in the outer underground engineering construction of Current Domestic
It is divided into two major classes: (1) provisional measures engineering --- block water cofferdam and seepproof screen, i.e., with bagged cement or concrete matched shuttering
Certain thickness weir body or wall are made, water burst outflow is delayed or separate；(2) permanent measures engineering-water dam,
Pass through a kind of mine water prevention facility for band door that cutting is arranged in roadway surrounding rock.
The method of above-mentioned two classes control water burst, existing defect have: 1, higher to site operation environmental requirement；2, construction consumption
When it is longer；3, block water cofferdam and seepproof screen be it is disposable, can not reuse, there are waste of material and the later period also needs to dismantle；4,
Water dam can only fixed location installation, mobility it is poor, and require be mounted on wall rock condition stablize location, simultaneously close off gate
After can not grasp water level and hydraulic pressure in real time.
