Abstract

The utility model discloses a water spray device for dripping and maintaining concrete on a high pier. The water spray device for dripping and maintaining the concrete on the high pier comprises a water source and a water pump, and is characterized in that the input end of the water pump is connected to the water source through a pipeline, and the output end thereof is connected to a main water pipeline through a pipeline; a branch pipeline is connected to the main water pipeline in parallel, the other end thereof is connected with a valve; the other end of the valve is connected with a water spray pipeline; water spray holes are formed on the wall of the water spray pipeline; and the water spray pipeline is mounted at the top end of the high pier. The utility model has the advantages of simpleness, convenient operation, saved time and labor, low cost and good maintenance effect; a plurality of piers can be maintained within 24 hours continuously; and the maintenance requirements of the prior durable concrete can be fully satisfied. By adopting the utility model, after the piers are dropped and maintained, the surface of each pier body is free from crack; the strength yield of the concrete reaches 100 percent; and the maintenance efficiency is improved by above 3 times. The utility model can be widely applied to the maintaining construction of the high piers on highways and railways.

Description

The drip water injector of curing concrete of Bridge High-pier

Technical field

The utility model relates to the concrete health in complex-terrain place, is specifically related to the drip water injector of curing concrete of Bridge High-pier.

Background technology

The maintenance of concrete construction is very crucial, especially the concrete maintenance of mountain area thin-walled hollow pier, the bad concrete surface cracking that causes of concrete curing, late strength of concrete can not meet design requirement etc., all bring a lot of unnecessary troubles to the quality of structure own and the examination of handing over, may cause this concrete work to be scrapped when serious.As general concrete health is to adopt covering earlier or the watering of parcel back to keep concrete surface moistening, the pier stud maintenance not high as basis, cushion cap, pier shaft, and railway or highway bridge with a varied topography, steep area, high slope, mountain need be crossed over river valley, zanjon, bridge pier is often up to tens meters even rice up to a hundred, and adopt erection without scaffolding more, just can't carry out health with conventional method.If concrete surface adopts conventional method parcel nonwoven or plastic foil, it is very difficult to operate, even after wrapping up well, wind one blows, very easily damages, and does not reach the parcel maintenance effect; Large tracts of land health water promotes problem, especially summer temp height besides, and water evaporates is fast, and each bridge pier all need be joined special messenger's maintenance, exist time-consuming, and the unconspicuous problem of maintenance effect.Unit in charge of construction is perplexed in the health of high pier stud always, and there is the referential defective of no mature technique in this area aspect the health of high pier stud.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, easy to use, time saving and energy saving, the maintenances simultaneously of many bridge piers, and its maintenance effect can guarantee the drip water injector of curing concrete of the Bridge High-pier of the curing requirements of the high pier durability concrete of no support.

In order to overcome the deficiency of the high pier maintenance difficulty that has erection without scaffolding now, the technical solution of the utility model is to solve like this: the Bridge High-pier concrete adopts the water injector maintenance of dripping, this device comprises water source and a water pump, special character of the present utility model is that the input of water pump is connected in the water source by pipeline, the output of water pump is connected on the main water pipeline by pipeline, at least one branch pipe(tube) in parallel on the main water pipeline, the other end of branch pipe(tube) is connected with valve, the valve other end is connected with water pipeline, diameter is just opened in water pipeline tube wall inboard along girth to multi-compartment 10cm be 2 millimeters water spray eye, water pipeline is installed in the Bridge High-pier top, and twines a week with nonwoven.

The utility model compared with prior art, have simple, easy to use, save time, laborsaving, cost is low, a plurality of bridge piers can uninterrupted maintenance in 24 hours simultaneously, maintenance effect well can satisfy the curing requirements of present durability concrete fully, the pier shaft surface does not almost have be full of cracks after the maintenance, the concrete strength qualification rate reaches 100% to adopt the novel bridge pier of this reality to drip, and maintenance efficient has improved more than 3 times.Be widely used in the maintenance construction of highway, railway high pier.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is A-A schematic cross-section of Fig. 1.

The specific embodiment

Accompanying drawing is embodiment of the present utility model.

Below in conjunction with accompanying drawing summary of the invention is described further:

With reference to Fig. 1, shown in Figure 2, the drip water injector of curing concrete of Bridge High-pier, comprise water source 1 and a water pump 2, the input of water pump 2 is connected in the water source 1 by pipeline, the output of water pump 2 is connected on the main water pipeline 3 by pipeline, four branch pipe(tube)s 4 in parallel on the main water pipeline 3, the other end of four branch pipe(tube)s 4 respectively with valve I, valve II, valve III, valve IV connects, the valve I other end is connected with water pipeline 5-1, valve II is connected with water pipeline 5-2, valve III is connected with water pipeline 5-3, valve IV is connected with water pipeline 5-4, it is 2 millimeters water spray eye that a diameter is just opened to multi-compartment 10cm in water pipeline perisporium inboard, and water pipeline is installed in the Bridge High-pier top, and twines a week with nonwoven.

The lift of water pump 2 may be selected to be 80 meters～150 meters, power is 5.0KW～7.5KW, φ 80 high-pressure water pipe that can connect full-bridge are main water pipeline 3, main water pipeline 3 can be controlled valve I, valve II, valve III, the valve IV of each pier shaft maintenance, the last branch pipe(tube) 4 control water pipelines 5-1～5-4 of each pier shaft.Each bridge pier place is provided with a subtube 4, subtube 4 is the high-voltage tube of diameter phi 30mm, length is greater than the height of bridge pier, and use valve I, valve II, valve III, valve IV connects, the other end at subtube 4 is connected with the water pipeline 5-1～5-4 that hard plastic tube is made, water pipeline 5-1～5-4 is around one week of pier shaft, the inboard water spray eye that φ 1～3mm is set every 3cm～10cm, the valve I that main water pipeline 3 connects, valve II, valve III, valve IV is placed on the ground, and each bridge pier is installed a branch pipe(tube) 4 and water pipeline 5-1～water pipeline 5-4.

In sum, using method of the present utility model is summarized as follows:

1, determines the quantity and the position of the required maintenance pier shaft of bridge;

2, water pump 2 is installed, is connected trunk line 3, by valve I serial connection branch pipe(tube) 4, connect water pipeline 5 at last, and water pipeline 5 is hung on the template, curing means connects to be finished.

When 3, pier shaft needs maintenance, connect water pump 2 power supplys, water is sent into pipeline, curing water is delivered to the pier shaft of required maintenance by valve I, by water pipeline 5 water on bridge pier top is gone downstream along bridge pier at last, promptly reach curing requirements after watering continuously, when not needing maintenance, as long as valve-off promptly stops maintenance.

4, adopt the maintenance of the utility model device, the pier shaft concrete is remained under the moistening health state, efficiently solve the difficult problem of pier shaft concrete surface cracking, and guaranteed effective lifting of concrete strength; But also accelerated construction speed.
