Abstract
The utility model relates to a concrete pier sprinkling and maintenance device, which comprises sprinkling pipes arranged at the periphery of the top of a pier and provided with spray holes thereon, wherein the sprinkling pipes are connected with a water tank through pipes, valves and pumps. The device solves the problem in automatically sprinkling and maintaining the concrete piers. The prier body can be maintained uniformly from top to bottom to obviate the formation of dry-wet circulation, so as to overcome the disadvantage of nonuniform water sprinkling maintenance of the pier body in the prior art and better solve the surface concrete cracking problem of the pier body. The concrete pier sprinkling and maintenance device has the advantages of flexible and convenient construction operation, water conservation, material consumption reduction, cost reduction, obviation of white pollution, and environmental protection, and can achieve automatic pier sprinkling maintenance. The device can be widely used for various concrete pier sprinkling maintenance systems.
Description
Affiliated technical field
The utility model relates to a kind of concrete pier curing means, particularly a kind of concrete pier spray curing means.
Background technology
For cup shake appears in concrete surface after preventing the bridge pier form removal, according to pertinent regulations, the concrete heat-insulating moisture-keeping maintaining is no less than 14 days requirement.Traditional pier shaft maintenance process is to adopt artificial watering moisture-keeping maintaining or non-woven geotextile parcel to add water proof plastic sheeting moisture-keeping maintaining.Traditional maintenance process and technology have the following disadvantages: (1) waste water resource; (2) make pier shaft bottom, job site concrete surface produce " mud stain " phenomenon because of curing period is long; (3) form white pollution after the plastic sheeting weathering; (4) the artificial maintenance difficulty of high pier is bigger, can cause the maintenance of pier shaft concrete surface inhomogeneous; (5) construction cost is higher.
Summary of the invention
Its purpose of the utility model just is to provide a kind of concrete pier spray curing means, can realize the maintenance of concrete pier automatic spray, has constructing operation flexibly, conveniently, characteristics such as water saving, but economical with materials reduces cost; Avoid white pollution to accomplish environmental protection.
The technical scheme that realizes above-mentioned purpose and take is, is provided with spray header around the bridge pier top, and described spray header is provided with spray apertures, described spray header by the road, valve, pump is connected to water tank.
Compared with prior art this device has the following advantages.
1,, thereby can realize the automatic spray maintenance owing to adopted the design of concrete pier automatic spray maintenance, have constructing operation flexibly, convenient, characteristics such as water saving.
2, owing to adopted the design of concrete pier automatic spray maintenance, pier shaft maintenance from top to bottom is even, avoids forming drying and watering cycle, has overcome the uneven disadvantage of pier shaft concrete watering maintenance in the past, has better solved pier shaft surface crack on concrete problem.
3, owing to adopted the design of concrete pier automatic spray maintenance, but thereby economical with materials reduce cost; Avoid white pollution to reach environmental requirement.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this apparatus structure principle schematic;
Fig. 2 is Fig. 1 vertical view.
The specific embodiment
Embodiment
Be provided with spray header 6 around bridge pier 4 tops, as shown in Figure 1, described spray header 6 is provided with spray apertures 8, described spray header 6 by the road 5, and valve 3, pump 2 is connected to water tank 1.
Described bridge pier 4 tops are provided with storage tank 7, and storage tank 7 outlets connect spray header 5.
Be provided with surrounding edge around described bridge pier 4 bottoms and form water tank 1.
Spray apertures 8 eye diameters on the described spray header 6 are 0.5～1mm, and the eyelet spacing is 30～50mm, and eyelet angle level is to the Dun Bi miter angle that tilts, apart from pier wall 50～100mm, as shown in Figure 2.
Certain newly built railway (Line for Passenger Transportation), the design speed per hour is 200 kilometers/hour, reserves 250 kilometers/hour speed-raising requirements, the railroad bridge concrete designs and adopts high performance concrete by design in 100 years service life.Wherein, grand bridge 9 (11881.35m), bridge 3 (759.79m), 15 of jackshafts (1051.716) are arranged.Two-wire bridge pier pier shaft structure design is a rectangular hollow, interconnection single line bridge pier pier shaft structure design is the rectangular solid pier, the C30 high performance concrete is adopted in the design of pier shaft concrete, the railroad bridge pier shaft mainly is a concrete in mass simultaneously, early stage, the pier shaft inside concrete reached as high as 65 ℃ because of the thermogenetic temperature of aquation, for cup shake appears in concrete surface after preventing the bridge pier form removal, according to " railway concrete engineering construction technical manual " TZ210-2005 regulation, the concrete heat-insulating moisture-keeping maintaining is no less than 14 days requirement.Characteristics such as, bridge pier height many according to this bid section bridge, use for reference railway bridge pier concrete curing experience in the past, compare from aspects such as economic aspect, construction technology aspect, environmental protection aspect, construction operability, designed the maintenance scheme of a cover science: railway high performance concrete bridge pier spray curing system has obtained extensive promotion and application in the maintenance of railroad bridge pier shaft high performance concrete.The use principle of this system is to utilize the spray system of Dun Ding design that Dun Ding and pier shaft are carried out the periodicity maintenance after the water pipe system of tap water by the bridge group connected.
In each pier shaft bottom tee piece and control penstock (high pier is set up booster pump) are installed,, are adopted at Dun Ding water tank (can utilize empty Admixture case) is set, utilize the sprinkling truck to supply water for the pier shaft that tap water can't arrive.Water pipe adopts the flexible pipe of internal diameter φ 50mm to connect full-bridge at the bottom of the pier, and the pvc pipe of φ 22mm is adopted at pier shaft and top, and eye diameter is 0.5～1mm, and the eyelet spacing is 30～50mm, and eyelet angle level is to the Dun Bi miter angle that tilts, apart from pier wall 50mm.Physical dimension according to Dun Ding is installed along pinner and shade limit, top at the top, utilizes φ 8 reinforcing bars to fix.Spray system in time is installed after the pier form removal, lists this pier in the health plan according to the requirement of 14 days curing times.The scene is sent the special messenger to be responsible for operation and is carried out maintenance record, up to the maintenance expiration, till maintenance is qualified.Dismountable other bridge pier that utilizes in maintenance expiration back at 14 days reaches recycling.This system is applicable to all kinds of bridge piers of railway.
