Description

Expansion joints for bridges equipped with replacement system of drainage sheets and this construction technique

The present invention relates to an expansion joint device for a bridge equipped with a drainage sheet replacement system and a construction method thereof, and in particular, an a-type steel plate having an anchor plate attached to an end portion of an upper slab of a bridge, or an alternating chest wall, and is poured by placing slab concrete. An anchor plate of the expansion joint is installed on a pair of vertical plates, and the concrete is filled in the space of the anchor plate to absorb the load distribution and vibration (shock) generated by the vehicle load when the vehicle passes. The slab end of the bridge increases the durability of the concrete and reduces the damage. The drainage sheet can be removed at any time by using the drainage sheet replacement system at the bridge or alternating inspection road without control of the vehicle. The bridge is equipped with a drainage sheet replacement system that can be used to clean foreign materials at the same time. It relates to a sound device and a construction method thereof.

Generally, in order to cope with the expansion and expansion of the bridge according to the temperature change, the bridge is divided into several spans in the longitudinal direction of the bridge, and expansion joints are installed between the divided upper structures for safe vehicle traffic. .

And in the lower part of the expansion joint device is installed a drain sheet to prevent the deterioration of function due to the bridge bearing corrosion and concrete corrosion by preventing the free induction drainage of the road surface water and the road surface water and various foreign substances below the bridge flow path do.

Here, the drainage sheet as described above is filled with foreign matter accumulated in the drainage sheet for many years, so that the road surface water does not fall or the road surface water overflows to the alternating and pier coping floor, it just flows out, tolerate the load and torn, or as needed In case of cleaning the foreign matter, there was a problem in that the maintenance of the drain sheet was difficult.

In order to replace the drain sheet, the vehicle must be controlled by lane to crush the non-concrete concrete in the bridge slab clearance and block out, and all the expansion joints and drain sheets must be replaced. There is a problem in that drainage, economical efficiency and water retention are significantly reduced.

Figure 1a is a cross-sectional view showing the installation state of the conventional drainage sheet for finger-type expansion joint, the conventional drainage sheet for finger-type expansion joint is a structure that is fixed to the side of the slab anchor bolt, after the long-term use It is very difficult to clean the deposited foreign materials, and when the drain sheet is torn due to the weight of the deposited foreign materials, it is necessary to crush the non-concrete concrete in the slab gap part to block out and replace the expansion joint and drain sheet together. Serious problems are caused.

In addition, when the drain sheet replacement and foreign matter cleaning on the bridge is carried out because the vehicle control is made for each lane, there is a problem that the traffic jam inevitably occurs, it is not possible to quickly replace and clean the drain sheet in a short time.

In addition, Figure 1b is a cross-sectional view showing the installation state of the conventional drainage sheet for rail-type expansion joint device, a conventional drainage sheet for rail-type expansion joint device has a plurality of drainage sheet is sandwiched between the rail steel, Perfectly drained, foreign matter is deposited relatively less than the finger-type expansion joint has the advantage of easy to clean the drain sheet in the minimum time on the bridge.

In addition, the replacement of the drainage sheet, as well as the finger-type expansion joint device is a traffic control is made for each lane, there is a problem that requires a separate special equipment for the replacement of the drainage sheet.

And Figure 1c is a cross-sectional view showing the installation state of the conventional new finger joint expansion device drain sheet, the conventional new finger joint expansion device drain sheet is vulcanized attached to the drain sheet on the inner surface of the steel Road water is perfectly drained, and foreign matter is deposited relatively less than the finger-type expansion joint device has the advantage of easy to clean the drain sheet with a minimum time on the bridge.

However, when the drainage sheet is torn, it is impossible to replace only the drainage sheet at all. Therefore, the expansion joint and the drainage sheet must be replaced by crushing and blocking out the shrinkage-concrete concrete in the bridge slab clearance area under traffic control for each lane. There is a problem with this falling.

In addition, Figure 1d is a cross-sectional view showing the installation state of the drainage sheet for expansion joints on the conventional gravel gravel railroad bridge, the drainage sheet for expansion joints on the gravel island conventional railway bridge is installed a-type steel sheet on the side of the slab, the a-type steel sheet side After fixing the drainage sheet to the block-out part, reinforcement with reinforcing bar to pour non-concrete concrete, and fix the fixed size steel plate with a type A steel plate and nut, install gravel and install railway sleepers and rails. .

The drainage sheet for the conventional railway bridge gravel drawing expansion joint is very difficult to clean the foreign matter after a certain time, and if the foreign matter is deposited on the drain sheet and the drain sheet is torn by weight, the whole expansion joint and the drain sheet are replaced. As a result, economic and durability problems are serious.

In addition, it is necessary to replace the drain sheet and clean the foreign matter while controlling the train operation on the bridge, there is an inevitable problem caused by the control of the train operation and difficult to perform the replacement of the drain sheet in a short time.

On the other hand, as shown in Figures 1a to 1d, foreign matter is deposited on the drain sheet and the drain sheet is often torn by weight, so that the road surface water or foreign matter flows leaks and baektae phenomenon, bridges and alternating Deterioration and delamination, rust generation and deterioration of bridge bearings, foreign matter deposition, steel girder rusting, etc. occur, resulting in poor durability and shortened bridge life and excessive maintenance costs.

And the repairing method of the drain sheet is to break out the non-concrete concrete of the slab spacing into the bridge upper structure and the lower structure to block out and replace the expansion joint and the drain sheet repeatedly for each lane, serious economical and durability Problems are caused.

In addition, when the replacement of the drain sheet and cleaning the foreign matter on the bridge, the vehicle control is necessarily made, there is a problem of traffic jams inevitably occurs, there is a problem that can not be quickly replaced and cleaning the drain sheet in a short time.

Therefore, the present invention has been made to solve the above problems, the fixing of the expansion joint anchor connecting the gap generated between the bridge upper slab end and the slab end, or between the alternate chest wall is installed at the slab end It is a device that is fixed so that the vehicle can run safely and all static and dynamic loads can be transferred from the expansion joint to the structure, and the concrete has excellent adhesion strength with steel and concrete, Equipped with a drainage sheet replacement system that has high absorption rate, compressive strength to withstand vehicle load, resistance to chloride, waterproof performance against water ingress, easy maintenance, excellent airtightness, and increased durability. The purpose of the present invention is to provide a new expansion joint for bridges and construction methods thereof.
