Abstract
The invention relates to a method for plugging a power cable tunnel duct piece bolt hole, which comprises the following steps: firstly processing expansion and seam along a tunnel dust piece bolt hole; then, blocking an inner cavity, injecting slurry chemically and processing airtight so as to complete plugging treatment for a bolt hole. Compared with the prior art, the method is characterized by simple operation and convenient plugging and can quickly treat fissure appeared on the power cable tunnel duct piece bolt hole; in addition, corrosion-resistant performance is relatively good.
Description
Technical field
The present invention relates to a kind of method of leak stopping, especially relate to a kind of method of power cable tunnel segment bolt hole being carried out to leak stopping.
Background technology
Along with a large amount of construction and the operation in domestic and international tunnel, tunnel Longitudinal Settlement particularly longitudinal uneven subsidence shows especially gradually.There is excessive Longitudinal Settlement or differential settlement for various reasons in a large amount of soft soil tunnel, cause water seepage of tunnel and leak mud or local failure of structure, or internal construction generation Longitudinal Warping distortion, affect the normal operation in tunnel, there is necessarily potential threat to tunnel structure safety, the safety of operating and comfortableness, and then have influence on again the operation of surrounding and all kinds of structure in earth's surface.For traffic tunnel, if the longitudinal differential settlement in tunnel is excessive, the longitudinal difference of height in road surface will be caused excessive, and road surface difference of height and planarization have exceeded standard, during car operation, safety and comfortableness are just difficult to be protected, and cause ordinary maintenance and maintenance task to increase the weight of; For power cable tunnel, when longitudinal strain is excessive, subsidiary stress can be brought to make it be out of shape to cable, time serious, even can cause the destruction of cable, affect electric power conveying.Therefore the longitudinal differential settlement in tunnel causes huge economic loss to tunnel operation and management department and country, even causes serious social harmful effect.
Cable waterproof is the important component part of cable running safety management, power cable ducks in drink larger to the safe operation of power cable, aging effects for a long time, therefore, electric power tunnel waterproof problem is extremely important, as off quality in waterproof construction, impeded drainage leads to, to make in hole moist, to the durability of electromechanical facility and power cable in air quality, hole, that flexibility is is unfavorable.During runing, underground water usually through concrete lining deformation joint, constuction joint, crack even the passage seepage such as concrete pore enter in tunnel, cause the metallic structures such as cable bearer, fixture to be in wet environment and corrosion, mildew and rot, rotten, inefficacy occur, if drainage system system imperfection, tunnel or active well ponding, will have a strong impact on daily monitoring and the safe operation of cable.
Summary of the invention
Object of the present invention is exactly provide a kind of simple to operate to overcome defect that above-mentioned prior art exists, and the method for leak stopping is carried out in leak stopping easily to power cable tunnel segment bolt hole.
Object of the present invention can be achieved through the following technical solutions:
Power cable tunnel segment bolt hole is carried out to the method for leak stopping, it is characterized in that, first the method carries out expansion seam along tunnel duct piece bolt hole, then completes the leak stopping process to bolt hole by shutoff inner chamber, chemical grouting and close encapsulation.
The method specifically comprises the following steps:
(1) carry out the process of expansion seam along tunnel duct piece bolt hole, the degree of depth expanding the bolt hole after seam is 4cm, and width is 3cm;
(2) in the surrounding raggle of bolt hole, then embed PE foam strip wherein and carry out shutoff, and grouting nozzle is installed;
(3) go out to inject injecting paste material by grouting nozzle to seam and carry out ejection for water plugging;
(4) after slip casting completes, wait injecting paste material to solidify and remove grouting nozzle, then the injected hole at grouting nozzle place is installed in shutoff;
(5) one organic silicon water-proofing layer or epoxy resin waterproofing course are set at joint surface, namely complete the leak stopping to power cable tunnel segment bolt hole.
Described injecting paste material is polyurethane injection slurry or macromolecule injecting paste material.
Described macromolecule injecting paste material is acrylamide or Luo lignin.
Segment bolt in described bolt hole, for can turn bolt, embeds polysulfide sealing compound or water-swellable sealing compound after unscrewing.
Compared with prior art, the present invention is simple to operate, and leak stopping is convenient, can facilitate rapid must process the crack that power cable tunnel segment bolt hole place occurs, and corrosion resistance is better.
