Description

Pier post repair work for keep water}

The present invention relates to a water barrier of bridge repair work.

In the case of conventional pier construction, the pier construction is cemented in the concrete placing process because it adopts the method of placing concrete mortar after installing the formwork made of wood at the same time as the reinforcing bar on the foundation immediately after finishing the foundation work of the floor. Part of the mortar is leaked into the gap of the formwork, which causes the cement content to fall below the standard value. If the standard value is lowered, the concrete strength of this part is weakened, and this part is easily corroded and flooded. Will cause.

As a result, almost all of the bridges in the current national construction of bridges wear cave-like erosions like tooth roots that have been eroded and damaged by roots, and urgent repairs are required for this area. As the mortar is imprinted on the corroded area, the soldered part is easily damaged by the high pressure of the flowing water during flooding, and more parts are corroded at this time, so it is inevitable to newly construct the entire bridge. The inconvenience is, of course, that the people have to bear huge financial burdens.

Korean Laid-Open Patent Publication No. 95-29504 is a structure in which a first jacket and a second jacket are welded to a damaged part of a pillar, concrete mortar is injected into these jackets, and an anticorrosive anode is installed at the bottom of the jacket. By adhering to the above, while minimizing the damage of the reinforcing bars due to the electric method while improving the supporting strength of the damaged part, the method of improving the repair strength of the damaged part to the strength at the initial design is described. There has been an uncomfortable problem of welding.

In order to solve the above problems, the present invention is designed to prevent the flowing water during the bridge repair work, install a plurality of angle bars or piles around the piers, densely formed reinforcement horizontally between the angle bars or piles Next, the purpose is to provide a piers of pier repair work that can block the flow of water around the pier by putting a vinyl sheet on the outside of the angle bar or the pile and reinforcement.

In order to achieve the above object, the present invention installs a number of angle bars or piles with a conventional striker around the piers needing repair, and between the angle bars or piles after fixing the piers and angle bars or piles as supports. After forming a plurality of reinforcing rods on the side tightly to the outside of the angle bar or pile and the reinforcement to put a vinyl sheet to block the flow of water around the pier.

When described in detail with reference to the drawings as follows.

1 is a process flow chart of the present invention, Figure 2 is a water barrier installation of the present invention, Figure 3 is a pier repair work sectional view of the present invention, Figure 4 is a pier repair work plan of the present invention, Figure 5 is the present invention The bottom of the water barrier is shown in detail, the reference numerals of the pier (1), angle bar or pile (2), support (3), reinforcement (4), vinyl sheet (5), external formwork (6), internal formwork (7), clay bags (8), reinforcing bars (9), reinforced bridges (10), cement mortar embedded vinyl (11) can be seen.

As shown in FIG. 2, a plurality of angle bars or piles 2 are installed around the pier 1 which needs to be repaired by using a normal hammer, and the pier 1 and the angle bars or piles 2 are supported by a support ( 3), after forming a plurality of reinforcing bar (4) in the lateral side between the angle bar or pile (2), and then a vinyl sheet on the outside of the angle bar or pile (2) and reinforcing table (4) (5) to block the flow of water around the corresponding piers (1),

In repairing the pier (1) in the water barrier device, the foundation work is performed by injecting cement mortar into a cylindrical shape by treating the pier (1) corrosion site of FIG. After finishing, the inner mold (7) is treated to form a cylindrical shape, and the outer side of the bottom between the outer mold (6) and the inner mold (7) is necessary after blocking it with a clay bag (8) to prevent water from entering the mold. After reinforcing the reinforcing bar (9) in the interior and then cement mortar through the upper trim of the inner formwork (7) while vibrating the mortar with a vibrator to allow the type mortar to osmosis sufficiently to the corrosion site for a certain period of time If left to cure the concrete layer and then dismantle the internal and external formwork (6,7) is to obtain a concrete layer, that is, the reinforced bridge (10) is a mixture of cement components evenly.

As such, the concrete mortar is vibrated by the type and the simultaneous vibrator to allow the concrete mortar to penetrate deeply into the erosion of the piers. At this time, make sure that the cement mortar liquid does not leak out.

In this way, after cement mortar type is left for a predetermined time (about 1 week), it is sufficiently cured, and then the inner and outer molds 6 and 7 are disassembled. At this time, the piers 1 becomes a concrete layer in which the cement mortar layer is equally formed. Since the durability is superior, the pier area is not oxidized or damaged unevenly due to the flow of water.

5 is to pump the cement mortar directly from the ready-mixed concrete car in the general large-size vinyl for the purpose of waterproofing the water permeated from the bottom to prevent the water permeating from the floor by installing on the bottom around the pier wells vinyl (11) with cement mortar embedded After the cement mortar is cured for 3 to 4 days, it shows a method to easily perform the construction process of Figure 3 based on the place.

As described above, in the piers of the bridge renovation work of the present invention, it is possible to easily block the flow of water at a small construction cost when the bridge renovation work, there is an effect that can be freely constructed in the piers repair work.
