Description
Technical field
Construction Technique of Underground Works field is the utility model is related to, particularly a kind of underground project waterproof structure.
Background technology
Underground engineering, refers to the engineering that various types of underground structures or structure are built in below ground soil layer or rock mass.
It includes：Underground railway, tunnel, parking lot, underground commercial center, people's air defence, basement and piping lane etc..With city capital construction not
Disconnected development, since the construction and use of underground engineering greatly increase the utilization rate of land use, underground engineering
Using waterproof problem that is more and more extensive, but being also faced with underground engineering at the same time.Underground project waterproof is whole construction quality
One key content, if the underground project waterproof structure without excellent sealing, it will cause the leakage of underground water, it is this long-term
Leakage can corrode bar construction in building concrete, and then would necessarily affect concrete building structures durability,
Security and use function.Therefore, underground waterproof structure is carried out to be necessary.
The common method of current underground waterproof engineering construction has outer anti-outer patch method and outer anti-interior patch method, and outer anti-outer patch method is
Treat structure abutment wall（Reinforced concrete structure exterior wall）After the completion of construction, directly coil waterproof layer is attached on abutment wall（I.e. underground is tied
Structure wall upstream face）, finally make the protective layer of coil waterproof layer；Outer anti-interior patch method is that construction is preceding first builds protection wall inside foundation pit,
Then coil waterproof layer is attached on protection wall, the method for finally pouring into a mould side wall concrete.Execution conditions are typically due to be limited
System, no operating space, when outer anti-outer patch method construction is difficult to carry out, using outer anti-interior patch waterproof construction method.
When actual Waterproofing Technology of Underground Works is using outer anti-interior patch, conventional method generally has two kinds：（1）Done in foundation pit side-wall
Steel sheet pile enclosure structure or concrete building enclosure, and the brick laid on edge fetal membrane in concrete building enclosure, fetal membrane of laying bricks will pass through
Paving blinding layer, numerous and diverse process such as build, plaster by laying bricks or stones；This process it is easily caused following problem：A. build by laying bricks or stones brick fetal membrane, plastering needed for
Long construction period；B. brick fetal membrane material requested cost and high labor cost；C. since long construction period, foundation pit expose for a long time,
Easily there is the problem of uplift of soil in foundation pit, adds the unstability factor of foundation pit enclosure structure；（2）Knot is gone along with sb. to guard him in concrete
Side wall screed-coat is performed on the inside of structure, then waterproof roll is fixed in process layer by steel nail, such as Application No.
201610230067.3 application for a patent for invention " a kind of construction method of Large Underground waterproofing work pre-installed and inverted adhered waterproof roll ",
This method is disclosed, the fetal membrane although invention need not lay bricks, reduces process, still needs to perform process layer, i.e. side wall
Screed-coat, to fill up gap or the groove between concrete building enclosure, there are the following problems for this engineering method：A. process layer needs
Carried out with pea gravel concreten or mortar repeatedly levelling, can be only achieved levelling effect, and can not be too thick, it is otherwise easily de-
Fall, such speed of application is slow, and cost is manually more, and long construction period, adds the unstability of foundation pit enclosure structure
Factor；B. waterproof roll is fixed in process layer by steel nail, can also causes the destruction to waterproof roll, and then influenced complete close
Seal waterproof effect.
