Description
[0001] The present invention relates to a prefabricated reinforced concrete wall structure capable of discharging road surface infiltration water of bridges and a construction method thereof, and more particularly, It has the function of improving the drainage function of the infiltration water on the road surface by separately installing a drainage inlet which can facilitate the removal, and securing the economical efficiency of construction by reducing the manpower by pouring the construction site and shortening the concrete curing period after construction The present invention relates to a precast concrete wall having an advanced function and a construction method thereof.
Generally, the present drainage system of a bridge road surface is provided with a system for installing a catch on the side of a bridge wall or a center separator of a bridge top plate, and connecting the drainage pipe to the drainage pipe. This may require frequent maintenance due to clogging of the drain pipe. That is, clogging of the bridge gutters, clogging of the connection of the drain pipes, and clogging of the bending part.
Also, since the spacing between the drains is wide, when the drainage is clogged, the drainage efficiency is drastically lowered due to the increase of the drainage distance. The rate of traffic accidents in the bridge section is slightly higher than that in the other sections.
In recent years, a pore pipe for introducing and discharging the infiltration water from the road surface of the bridge is provided between the catcher and the catcher. However, in case of installing such a pipe, the work process is complicated and the construction cost and the construction period are increased.
As a prior art related to the present invention, there is a "dirt removal structure of a bridging drainage facility" as a Korean Utility Model Registration No. 20-0345926 (registered March 23, 2004). A check part is provided at the rear side of a bending part connected to a bending part of a drain pipe facility disposed in a bridge, a dirt receiving part is provided at the bottom, and a cover body, which is openably and closably connected to the open end, A "+" curved waste outlet; There is provided a "T" type straight pipe dirt outlet which is connected to a straight pipe and a straight pipe of a drain pipe facility and which is provided at the lower end thereof with a cover body which is detachably connected to an open end of the cover body so that dirt is deposited inside the pipe The present invention provides a dirt removal structure of a bridge drainage facility which can easily remove drainage of rainwater on the road surface of a bridge top plate when the drainage is not smooth.
However, the prior art is disadvantageous in that the drain pipe facility is installed on the outer side of the bridge, resulting in a poor appearance, and if the dirt is not removed in time, the drainage channel is clogged, causing plants to grow on the clogged area or polluting the drainage port.
Also, according to the conventional technology and patents related to the advanced water supply facility, in Korean Patent No. 10-1175998, the road surface drainage facility of a bridge has a certain width and depth along the edge or center of the road surface of the bridge, And a drainage receiving block having a drainage passage extending along the longitudinal direction and allowing rainwater to flow into the drainage passage from the front side is connected to the drainage receiving block and the section where the drainage receiving block is installed is drained And a foreign matter removing cover is provided between neighboring water discharge pouring blocks to remove foreign substances blocking the passage. A built-in preheating water receiving facility having a function of discharging the road surface infiltration water of the bridge is disclosed,
Korean Patent No. 10-1088163 discloses that a first guide portion is formed in a lengthwise direction of a bridge to easily capture the inside of the bridge, and the second guide portion and the drain portion can stably discharge the excellent And a method of constructing the same.
Also, Korean Patent No. 10-1124694 has a first guide portion formed to be long in the longitudinal direction of the bridge so that the construction is simple and the maintenance and repair work is easy, and the inside of the bridge can be easily collected. And a drain can be stably exhausted by the drainage section, and a drainage pipe for a bridge and an installation method thereof are disclosed.
However, since the above-mentioned construction method has already been carried out, the collector pipe and the side water pipe are installed on the existing bridges of the existing bridges, and the installation method of the brick wall on the construction site by the machine is the non-standardization of the product, There are some disadvantages to quality control,
The bridge is installed on the side of the bridge and the device for the drainage is installed. As a result, the overflow phenomenon occurs in the drainage system when the heavy rainfall occurs and the drainage pipe is frozen in the cold region. On the side there is a very disadvantage. In addition, foreign matter may accumulate in the subordinate drainage device outside the barrier wall at all times, and the aesthetic pipe may be somewhat defective, causing problems in drainage, and may act as a load on the barrier wall, thereby affecting the life of the bridge.
In addition, the above-described techniques may cause a problem that the concrete material generated when the barrier wall is poured into the catching hole when the barrier wall is poured in the construction site is infiltrated and the catching hole is clogged. Accordingly, leakage may occur in the horizontal drainage connecting portion, And dewatering device are connected by bolts. Therefore, it is structured to be very vulnerable to vibration of bridges, and additional manufacturing costs are required when a vertical pipe connection is required.
In addition, reinforcing bars should be installed at the interval of the horizontal pipes due to the interference of the reinforcing bars, and there is a problem that the side treatment of the formwork is somewhat unstable when the horizontal pipe is installed.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve the conventional problems, and it is an object of the present invention to provide a bridge structure for a bridge, which is linearly drained from a road surface of a bridge to improve drainage efficiency during heavy rainfall, The present invention relates to the provision of a concrete structure with a built-in water facility having a function of discharging the infiltration water from a road surface of a bridge, and a method of constructing the concrete structure. And the concrete structure including the advanced water function of the present invention is manufactured by the pre-casting process in the factory, so that the construction period according to the manpower, the construction period and the concrete curing period is shortened compared to the existing concrete structure placing method in the field It has the advantage of being able to secure uniform quality by factory production and management The present invention is to provide a precast concrete wall structure and a method of constructing the same, which are capable of improving the durability of the bridge due to low exposure to the external environment.
In order to accomplish the above object, there is provided a prefabricated concrete wall structure and a construction method thereof for discharging road surface infiltration water of a bridge according to the present invention,
The pre-cast concrete wall for receiving the road surface infiltration water discharging function of the bridge is provided with the steps of installing a communication pipe or the like inside the wall by referring to the design of the installation site; Providing a drainpipe furnace provided with an inlet with a wire mesh or the like to prevent infiltration of infiltration water from the road surface into the barrier wall and to prevent clogging of the inflow port by foreign matter or gravel; Characterized in that it comprises the step of making concave and convex forms on the side walls of the barrier for the connection of the barrier and the barrier.
Also, the pre-cast concrete wall construction method for discharging road surface infiltration water of the bridge,
Precast Concrete Fitting of Concrete Slab Considering Construction of Fireproof Wall Structure; For the installation of precast concrete wall, welding step between reinforced concrete slab and reinforced concrete wall after installation using barrier; Casting a concrete slab to integrate the precast concrete slab and the precast concrete wall; .
