Abstract
The utility model relates to a hidden trench for concentrated seepage water guidance and drainage of an existing tunnel in a cold area. The hidden trench for the concentrated seepage water guidance and drainage of the existing tunnel in the cold area is characterized in that a draining hidden trench is annularly arranged in a tunnel lining along a tunnel; water guiding drill holes are formed in the draining hidden trench in the surrounding rock direction; a draining half pipe is arranged inside the draining hidden trench; the water guiding drill holes are connected with the draining half pipe; the draining half pipe is connected with a tunnel draining ditch; the draining hidden trench is filled with cement mortar till the draining hidden trench is flush with the surface of the tunnel lining; cement mortar is plastered on the surface of the tunnel lining along the draining hidden trench; an extruded insulation board is adhered to the cement mortar and is fixed on the tunnel lining by a long plastic expansion nail; and the outer part of the extruded insulation board is sealed with the cement mortar by nylon gridding cloth. Multiple water guiding drill holes are formed in a seeping position of the tunnel lining, and water in surrounding rock is guided into the draining half pipe which is annularly arranged along the tunnel and drained out, so that seepage water controlling effect of the tunnel in the cold area is improved.
Description
One, technical field
The utility model relates to a kind of cold district's existing tunnel concentrative seepage ejectment water undercut in the Curing of Tunnel Diseases.
Two, background technology
Tunnel Water Leakage is one of domestic and international tunnel Common Diseases, and the regulation of percolating water is the technical barrier that the domestic and international project interface is faced.Tunnel Water Leakage harm is very large, and service life of equipment in the service life in minimizing tunnel and the tunnel has worsened tunnel environment, affects traffic safety, has increased the operation maintenance cost; Simultaneously may cause surface collapse again, affect surrounding enviroment.
In China's new highway, railway tunnel, have much to be located in frigid plateau region.The relatively general weather conditions of the water leakage defect that produces in the frigid plateau region tunnel are more serious, can have a strong impact on tunnel operation and traffic safety.Behind the frigid plateau region tunnel generation water leakage defect, not only percolating water can affect normal use and the life-span of equipment in the tunnel, and after the circulation of the concrete at percolating water place process thawing, the intensity decrease, even Local Cracking, can bring great hidden danger to structural safety, flowing water has a strong impact on traffic safety icy on road simultaneously.
Traditional control measures comprises: the one, and the earth's surface is cut, row, precipitation, namely cuts off near the source of the underground water tunnel, reduces the water pressure of tunnel lining structure; The 2nd, shutoff slip casting in water route in the hole is namely effectively repaired and is filled tunnel lining internal flaw and lining cutting space behind, forms a water barrier that jointly is comprised of tunnel lining and country rock; The 3rd, backfill grouting between lining cutting and the preliminary bracing is pressed into space between lining cutting and the preliminary bracing with cement grout by grouting pump, eliminates water space and underground water migrating channels in the liner structure; The 4th, the inner slip casting of liner structure, namely the principle of applicating road chemical grouting is carried out ejection for water plugging, and space, filling crack reaches the purpose of sealing.
The technical measures high by costs such as shutoff and fillings can play certain effect really, but As time goes on weaken with effect, and can't eradicate the generation of Tunnel Water Leakage; Simultaneously, consider the special hydrology geological conditions in highland and severe cold tunnel, the percolating water management measure of the adaptation tunnel in cold area that a kind of cheap, easy construction of exigence, effect are permanent.
Three, summary of the invention
The utility model purpose is to administer for the percolating water of cold district existing tunnel, and a kind of cold district's existing tunnel concentrative seepage ejectment water undercut is provided, thereby improves regulation effect, minimizing operating cost, has simultaneously stronger operability.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of cold district's existing tunnel concentrative seepage ejectment water undercut, it is characterized in that: along the tunnel hoop draining undercut is set in tunnel lining, in undercut, perform diversion boring to the country rock direction, the draining semicanal is set in the draining undercut, diversion boring is connected with the draining semicanal, the draining semicanal is connected with the tunnel drainage ditch, the draining undercut is filled to concordant with the tunnel lining surface with cement mortar, smear cement mortar along the draining undercut on the tunnel lining surface, plastic extrusion heated board is attached on the cement mortar, be fixed in the tunnel lining with long plastic expanding nail, plastic extrusion heated board external application nylon grid cloth and cement mortar are sealed.
Adopt this cold district's existing tunnel concentrative seepage ejectment water undercut percolating water can be drawn from tunnel surrounding inside, improved the effect that percolating water is administered, and simple in structure, strong operability, cost is lower, and the antiseep effect is lasting; Simultaneously, can prevent that tunnel in cold area percolating water is at the inner freeze-thaw damage that produces of lining cutting.
Four, description of drawings
Fig. 1 structural representation of the present utility model (detail drawing)
Fig. 2 structural representation of the present utility model (elevation)
Five, the specific embodiment
With reference to Fig. 1～2, a kind of cold district's existing tunnel concentrative seepage ejectment water undercut, it is characterized in that: along the tunnel hoop in the tunnel lining 6 interior draining undercuts 2 that arrange, in undercut, perform diversion boring 1 to the country rock direction, at the draining undercut 2 interior draining semicanals 3 that arrange, diversion boring 1 is connected with draining semicanal 3, draining semicanal 3 is connected with tunnel drainage ditch 7, draining undercut 2 usefulness cement mortar are filled to concordant with tunnel lining 6 surfaces, smear cement mortar along draining undercut 2 on tunnel lining 6 surfaces, plastic extrusion heated board 4 is attached on the cement mortar, is fixed in the tunnel lining 6 with long plastic expanding nail 5, plastic extrusion heated board 4 external application nylon grid cloths and cement mortar are sealed.
Operating principle: the lining cutting behind underground water in the country rock enters draining semicanal in the draining undercut by diversion boring, and then drainage prevents that by plastic extrusion heated board the water in the draining semicanal from freezing to the tunnel drainage ditch.
