Abstract
The present invention relates to an apparatus for constructing a concrete structure, and moreover, it is possible to more easily construct a concrete structure including a central separator made of a concrete protective wall in the center of the road and a retaining wall made of a concrete protective wall in the street. By covering concrete on the outer circumferential surface of the pre-installed concrete barriers, the concrete barriers installed on the road can be retrofitted, and the cost required can be greatly reduced. Furthermore, the concrete through the plastering part rotating in contact with concrete There is an effect that can be compacted so that cracks do not occur in the construction quality can be greatly improved.
Description
The present invention can more easily construct a new concrete structure, including a median divider consisting of a concrete protective wall in the center of the road and a retaining wall made of a concrete protective wall on the roadside, as well as on the outer surface of the concrete protective wall installed on the road. The concrete protection wall installed on the road can be improved by covering the concrete, and the cost can be greatly reduced. Furthermore, the concrete is prevented from cracking through the plastering part rotating in contact with the concrete. The present invention relates to a concrete structure construction device that can greatly improve construction quality.
In general, roads including exclusive roads such as expressways are installed with rails or concrete barriers, that is, central dividers, in order to prevent center line invasion and to prevent visual interference caused by headlights of opposite lanes. In order to ensure higher safety, the central partition is constituted by a concrete barrier.
Concrete protection wall constituting the central separator is installed on the highway has a height of about 860mm from the road surface and the shape of the concrete retaining wall of the floor width structure of about 620mm ~ 670mm, and has a structure of installing a shielding net of about 400mm on the top.
In the case of a large vehicle, the concrete barrier wall easily enters the opposite lane and may cause a large traffic accident, and the anti-glare network also increases the risk and fatigue of night driving because it does not completely block the headlights.
Due to these problems, in accordance with the aging trend of the existing median separator, the existing median separator is dismantled, the width of the floor is increased from 700mm to 720mm, and the anti-glare net is unnecessarily raised to a height of approximately 1270mm.
However, the method of dismantling existing concrete barriers and installing concrete barriers of a new standard has enormous cost and environmental problems.
The present invention has been created to solve the above problems, it is possible to more easily construct a new concrete structure, including a central separator consisting of a concrete protective wall, etc. in the center of the road, and a retaining wall made of a concrete protective wall, etc. on the roadside. In addition, it is possible to improve the construction of the concrete protective wall pre-installed on the road by overlaying the concrete on the outer surface of the concrete protective wall pre-installed on the road, as well as to reduce the cost required, furthermore, especially in contact with the concrete The purpose of the present invention is to provide a concrete structure factory value that can be compactly finished to prevent cracking in the concrete through the plastering part can greatly improve the construction quality.
The present invention for achieving the above object is the main body is formed with an inlet is introduced into the concrete, the space in communication with the inlet is formed; Provided at the rear side of the main body, the plastering unit to rotate in contact with the concrete introduced into the space through the inlet; provides a concrete structure factory comprising a.

In addition, the drive member is preferably made of a hydraulic motor.
Furthermore, it is preferable that the curing agent injection unit for spraying the curing agent to the concrete on the rear side of the main body.
In particular, the curing agent injection unit is provided on the rear side of the main body, and the curing agent inlet pipe in which the curing agent is introduced; A nozzle which is provided at a predetermined interval in the curing agent inlet pipe and sprays the curing agent into concrete; It is preferably made to include; a curing agent supply member for supplying a curing agent into the curing agent inlet pipe.
In addition, it is preferable that an elastic member is provided between the rotary shaft and the rotary blade.
The present invention can more easily construct a new concrete structure, including a median divider consisting of a concrete protective wall in the center of the road and a retaining wall made of a concrete protective wall on the roadside, as well as on the outer surface of the concrete protective wall installed on the road. The concrete protection wall installed on the road can be improved by covering the concrete, and the cost can be greatly reduced. Furthermore, the concrete is prevented from cracking through the plastering part rotating in contact with the concrete. As it can be finished, there is an effect that the construction quality can be greatly improved.
