Abstract
The invention relates to a method for constructing mass concrete, and belongs to the technical field of concrete construction. The method for constructing the mass concrete comprises a construction process of pouring concrete, and is characterized in that the concrete is poured for several times, so as to finish the construction of the mass concrete through the mode of pouring the concrete for several times. The method has the advantages that the method has simple process, convenient construction and low construction cost, is not limited by factors such as other construction conditions and the like, can be applied to any mass concrete construction site, and ensures the construction quality of the concrete.
Description
Technical field
The invention belongs to the concrete construction technology field, particularly relate to a kind of mass concrete construction method.
Background technology
At present, mass concrete construction method is to adopt a concreting to finish job practices, owing to reasons such as concrete in mass heat radiations, causes problems such as distress in concrete.General adopt insulation or in concrete mode such as the logical cooling water of pipe laying solve heat dissipation problem, such job practices trouble, influence programming, the construction cost height, restricted by other condition elements, and construction quality still can't effectively be ensured, causes the follow-up use hidden danger of concrete in mass, influences security performance.
Summary of the invention
The present invention provides a kind of mass concrete construction method for solving the problem that prior art exists.
Order of the present invention provides that a kind of to have activities simple, easy construction, the mass concrete construction method of characteristics such as construction quality is secure.
Mass concrete construction method of the present invention adopts following technical scheme:
A kind of mass concrete construction method comprises the concrete pouring construction process, is characterized in: concreting divides to be carried out for several times, finishes mass concrete construction by several concreting mode.
Mass concrete construction method of the present invention can also be taked following technical measures:
Described a kind of mass concrete construction method is characterized in: concreting for several times is twice concreting.
Described a kind of mass concrete construction method is characterized in: twice concreting is to carry out the concreting first time earlier, leaves the hole when building on concrete, carries out the concreting second time then in the hole of leaving for the first time and finishes.
Described a kind of mass concrete construction method is characterized in: pitch of holes is 300-1000mm.
Described a kind of mass concrete construction method is characterized in: concrete hole is cylindrical.
Described a kind of mass concrete construction method is characterized in: cylindrical hole is quincunx arrangement mode.
Described a kind of mass concrete construction method is characterized in: the diameter of cylindrical hole is 300-1000mm.
Advantage that the present invention has and good effect:
The present invention is owing to adopted the brand-new technology scheme, and therefore, it is simple that mass concrete construction method has activities, easy construction, construction cost is low, not restricted by factors such as other execution conditions, applicable any big long-pending concrete construction site, advantage such as concrete construction quality is secure.
Description of drawings
Fig. 1 is a mass concrete construction bridge construction schematic diagram of the present invention;
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Among the figure, 1-bridge, 2-cylindrical hole.
The specific embodiment
For further understanding technology contents of the present invention, characteristics and effect, enumerate following example now, and conjunction with figs. is described in detail as follows:
With reference to accompanying drawing 1 and Fig. 2.
Embodiment
A kind of mass concrete construction method, in the large bridge work progress, concreting is divided into twice to be carried out, twice concreting is to carry out the concreting first time earlier, leave blind hole when building on concrete, concrete blind hole is cylindrical, is quincunx arrangement mode, bore dia is 800mm, and pitch of holes is 800mm; During by concrete construction evenly quincunx arranging the mode of cylindrical hole is set, mass concrete construction is changed into non-mass concrete construction, thereby efficiently solves a series of problems such as heat radiation, crack of large volume construction.After for the first time building successfully, in the quincunx hole of leaving for the first time of arranging of cylindrical hole, carry out the concreting second time again, realize the large bridge casting of concrete in mass at last.This job practices activities is simple, and construction cost is low, not restricted by factors such as other execution conditions, and construction quality is secure.
