Abstract
The present invention discloses an inner repair technical method for water stopping belts of reinforced concrete channels. The method comprises the following steps of closing a gate, pumping water, removing mud, stopping leakage and water by flexible materials to keep flexible connection among sections, sealing seams by expansion rubber, flattening quickly-dried cement, and installing a semicircular rubber water stopping belt and a protecting layer, and the semicircular structure can permit a channel to bear a large settling amount. The present invention changes the traditional outer repair method, the ground does not need to be excavated, the repairing quality of the circumference of the channel is completely consistent, the leakage stopping effect is reliable, and the service life is extended. The present invention is suitable for water conservancy, national defense, electric power, environmental protection, personal protection and municipal engineering.
Description
The present invention relates to hydraulic engineering, belong to the culvert and channel water-blocking belt service technique especially.
Usually containing when canal or ejectment water channel road are built all is to adopt the ground excavation, and concrete structure is laid with burying, the different parts interface of containing canal and channel section with section between interface be rubber fastening band and connect.Day, ground generation differential settlement caused the rubber fastening band of interface to break, and misplaces between channel section and the section long afterwards, and the interface position earth that has is dashed empty by water, emit outside the culvert canal leaks in a large number.General method of repairing is to adopt the method for dispatching workers to do on-site repairs promptly to excavate ground, clear mud, and grout off, after the method but this dispatches workers to do on-site repairs, weak point were to excavate ground, the soil body was loosening, causes containing further sedimentation of canal or inclination.Simultaneously, built concrete foundation, leaked so can't repair culvert canal bottom owing to containing canal connection seam bottom.
The purpose of this invention is to provide a kind of steel concrete and contain the maintenance construction method of canal.One of its purpose is to make intersegmental connection flexible material, and handling flexibly can be born big differential settlement.Two of its purpose can find to contain inner other position hidden danger of canal.Three of its purpose is that repairing quality is in full accord around making the culvert canal.
Technical scheme of the present invention is to realize like this; the step of maintenance construction method comprises mud, grout off clearly; the main points of its step are: the envelope lock, draw water, clear mud, cleaning slit, surfacing, flexible material leak stopping, expanded rubber joint seal, efficient quick hardening cement is repaired and the leveling dislocation; coating adhesive, installation rubber fastening band are installed topping, waterstop two side seal mouths.
The shape of rubber fastening band is identical with the topping shape, is semicircle, can allows to contain canal bigger settling amount is arranged.
The present invention adopts inner repair technology method, has changed traditional method of dispatching workers to do on-site repairs, the ground bin need excavate and around containing in the canal repairing quality all can reach in full accord.Contain canal and press greater than amending the law outward in bearing, repairing effect is improved greatly, prolonged culvert canal application life.Adopt flexible material and handling flexibly leak stopping sealing reliability height, can allow to contain canal has bigger settling amount.
The invention will be further described below with reference to the accompanying drawing illustrated embodiment.
Fig. 1 is the present invention's generalized section of constructing.
Among Fig. 1, contain canal reinforced concrete structure 1, former rubber fastening band 2, waterstop section for rupturing among the figure.Flexible material 3 leak stopping.Flexible material is polyurethane or rubber fastening band.With the flexible material leak stopping higher tension and impact strength are arranged, good elongation per unit length and leak stopping performance are arranged.Make to contain still can keep flexible between canal section and the section and connect, improved culvert canal integral body leak-stopping performance, avoid the harm of differential settlement.Expanded rubber 4 joint seals, volume expansion behind the chance water reaches stagnant water effect preferably.With quick hardening cement 5 mending concrete breakages and leveling dislocation position, make surfacing, good seal performance.Template can be set, beat hole for the expansion bolt, the fixed expansion bolt.Coating adhesive 6 conforms to concrete and rubber fastening band on concrete surface.Rubber fastening band 7 and topping 8 are installed then, promptly are installed on the expansion bolt and fix, also can expansion bolt be set, fix with cementing agent.Topping 8 can be a stainless sheet steel, also can coagulate or epoxy resin and glass fabric with cyanogen.Waterstop 7 and topping 8 be shaped as semicircular structure, when containing canal and produce sedimentation again, can bear bigger settling amount, two sides of waterstop are flattened after with quick hardening cement 5 joint seals.
The present invention is applicable to hydraulic engineering, defence construction, power engineering, environmental protection, people's air defense and municipal engineering.
