Description
Technical field
Maintenance process and its curing means the present invention relates to a kind of water-saving type bridge pier column.
Background technology
As country is to the continuous input of infrastructure, urban viaduct and rural area, the construction of highway bridge in mountainous area are continuous
Development, bridge depth of beam are also constantly increasing.The pier stud of bridge plays supporting role in bridge, and the quality of pier stud quality is to bridge
Girder construction plays a very important role, and concrete strength is the important indicator for evaluating pier stud quality.Concrete strength is not only
It is related with raw material and construction technology, also there is direct relation with the maintenance of concrete.Pier stud body after the completion of concreting,
If concrete is in dry environment, moisture evaporation is too fast in concrete, concrete dehydration, and sheet decortication dusting then occurs in surface
Or the situation that powdery comes off；Meanwhile when concrete not yet possesses enough intensity, the premature evaporation of moisture can also generate larger
Contraction distortion, there is cup shake；The hydration of inside concrete causes crystal structure loose because dehydration cannot be carried out fully
It relaxes, strength reduction.Therefore, after the completion of concreting, pier stud body should be given as early as possible and covered and moisture-keeping maintaining of sprinkling water.Entirely
It is mulching straw seat on it after the completion of the concreting in face, moisture-keeping maintaining of sprinkling water.
But at present, for most of bridge pier column height at 10 meters or more, watering maintenance is extremely difficult, and the maintenance of pier stud body is mainly adopted
It is wrapped up with polybag, then watering is conserved manually.Since pier stud body is generally higher, artificial water application is difficult, and work is strong
Degree is high, and lower channel need to be set up by mechanical equipment or separately, causes the waste of the resources such as machinery, material, while also increases and support
The risk of shield personnel's personal safety, and nourishment's work watering amount is big, causes water resource serious waste.After curing period,
Quality is mostly undesirable, the reason is that curing time is inadequate, not in time, the surface watering of pier stud is uneven, causes pier for watering maintenance
Column intensity cannot reach design requirement, and the situation that pier stud body is done over again often occur.
China Patent No. 2008200300701 describes a kind of water injector of Bridge High-pier dripping water-curing concrete, adopts
Water is pumped into Bridge High-pier top with pump, water is sprayed into lower maintenance from Bridge High-pier from up to down from sparge pipe with holes.The water spray fills
Though putting better than artificial watering moisture-keeping maintaining, due to Bridge High-pier and the non-burnishing surface of pier damaged surface, water is from up to down from bridge
Under high pier spray during maintenance, under wind and external influence, water is not evenly distributed with pier stud dignity, and heat distributes in the concrete of pier stud body
It is too fast, water resource serious waste, it is impossible to be applicable in the construction on mountain area water shortage ground, after curing period, quality is also undesirable, it is difficult to push away
It is wide to use.
The content of the invention
Maintenance process and its curing means the object of the present invention is to provide a kind of water-saving type bridge pier column, can realize water-saving
Formula bridge pier column conserves, and pier stud body moisturizing heat dissipation is uniform, has economical and practical, and securely and reliably, water-saving and environmental protection, employment is few, pier stud
