Description

A Floor of Temporary Bridge for using Seet Pile and It's Constructing Method}

The present invention relates to a top plate of a perforated plate which is installed for the purpose of temporarily passing a temporary bridge or a subway construction work, and for securing a traffic, material storage, and a workplace, and in particular, a sheet pile developed for a temporary wall temporary facility. The present invention relates to a cross-linked top plate using a sheet pile for providing flatness and preventing slipping by using a top plate and paving concrete or asphalt on top thereof, and a construction method thereof.

Bridge construction is temporarily installed for the reconstruction of damaged sections for detours during construction for new construction, reconstruction, expansion, and reinforcement of bridges, emergency roads for disaster recovery, securing emergency military roads, or for building underground facilities such as subways. Unlike road bridges, it is a road facility that has to be installed quickly and with minimal construction costs according to various site conditions depending on its purpose of use.

Conventionally, the upper plate of the bridge as shown in FIG. 1 is provided with a method for arranging and installing iron beams (1) on the lower structure as shown in FIG. 1, and arranging and installing the iron porous plates (2) in the shape of a rectangular plate on the iron beams (1). It is common to construct through.

However, the construction of the crosslinked top plate using the iron porous plate as described above has several problems as follows.

First, since the surface of the perforated plate forming the road surface is smooth, frictional force is significantly smaller than that of asphalt or concrete road surface, and slipping occurs easily when snow or rain occurs, causing a traffic accident or a safety accident.

Second, because the unevenness and construction step due to the gap between the two perforated plates are formed, the flatness of the road surface is bad, which not only creates anxiety for the driver of the vehicle driving on the road, but also provides a cause for the failure of the vehicle If there were problems leading to traffic accidents.

Third, because there is no waterproof function, rainwater or sewage leaks through gaps or lifting hook holes at the parts where the ventral plates are connected, which not only makes the worker's work or inspector's actions unnatural, but also provides various causes of safety accidents. There was a problem that caused the failure of the facilities and work equipment under the perforated plate.

Fourth, the dust is passed through the gap and the lifting ring hole, such that the environment of the lower space is inferior, there is a problem that damages the health of the worker to avoid the lower work.

Fifth, since the perforated plate used as the upper plate material is manufactured in uniform dimensions, special functional workers with precision construction ability are required, and the labor cost is high, and the material cost is high and the transportation is easy because the amount of hardware is high and heavy in the perforated plate. There was a problem that the construction cost is increased by the result that is not easy and workability is poor.

Sixth, there is a problem in that the cost burden for the maintenance is frequent, because the frequent movement of the location occurs due to the movement of the position or the occurrence of a step by the traffic of the vehicle.

On the other hand, it was developed to prevent the slip of the conventional vehicle, the Korean Utility Model Publication No. 1999-0015930 and 1998-057334, the Korean Utility Model Registration No. 0163394, 0232743, 0234610 Ones and many other non-slip perforated plates have been disclosed.

These perforated plates are integrated by covering the surface of the steel plate with concrete or asphalt, and the surface of the concrete or asphalt with high friction forms the road surface, so the braking distance of the vehicle is shortened and the risk of traffic accident is reduced. It is true that to some extent.

However, these non-slip backing plates are also manufactured in a uniform size and are connected to each other. Therefore, there are problems due to gaps and connection roads of the connecting parts appearing in the steel backing plates described above, problems with high manufacturing costs, and difficulty in construction. Most problems such as problems, breakage and maintenance due to deformation are not overcome.

Accordingly, the present invention has been made to solve the conventional problems appearing in the upper plate of the temporary hole that is temporarily installed in the temporary construction or subway construction work for the purpose of securing the traffic, materials, workshops, etc. of the vehicle, The purpose of this is to use sheet piles developed and used for the temporary fences as bridge top plate, fill the main parts of the sheet piles with appropriate fillers, and carry out pavement work on the upper part to secure the frictional force of the driving vehicle. In addition to providing a high level of flatness, it is to provide a cross-linked top plate and a construction method using a sheet pile to prevent various traffic accidents and safety accidents.

Another object of the present invention can be maintained without damage or deformation until the completion of the main construction, such as bridge repair or subway construction after installation, bridge construction using a sheet pile to ensure a pleasant working environment of the lower space It is to provide a top plate and a construction method thereof.

According to the present invention having the above characteristics, without using a perforated plate that causes various problems in the past, while using a rigid and low-cost sheet pile as a structural material of the top plate concrete or asphalt pavement of the same material as the road surface of the general road thereon By implementing this, not only constructability is good and construction cost is low, but also greatly improves the running and safety of the passing vehicle, it is possible to fundamentally prevent various traffic accidents and safety accidents.

And since the upper plate has a structure that is entirely sealed by the packaging layer, work inhibitors such as sewage, rainwater or dust do not penetrate into the lower working space, thereby ensuring a comfortable and safe working space.

In addition, since there is no risk of being damaged or deformed due to no impact generated when the vehicle passes, there is an extremely advantageous advantage in terms of maintenance of bridge construction.

Hereinafter, the technical configuration of the present invention will be described in more detail with reference to the accompanying drawings of FIGS. 2 to 5 according to the construction example of the present invention.

The cross-linked top plate according to the present invention includes a plurality of H beams 10 installed at predetermined intervals on a lower structure, and a plurality of sheet piles mounted on and fixed to the H beams 10 while being orthogonal to the H beams 10 ( 20) and a packing layer 30 which is disposed on the sheet pile 20 at a predetermined thickness.

In constructing the structure of the upper plate, the H beam 10 is installed by supporting it on a lower structure (not shown), and the plurality of H beams 10 are arranged in parallel with a predetermined interval between the neighboring ones. Install in state.

The substructure differs depending on the structure to which the present invention is applied. In the case of temporary bridges, the main structure may be a main beam installed long in the direction of the bridge or bridges, and in the case of subway construction, it is usually settled on the ground using steel frames such as H beams. It can be a pillar to be built, the H beam 10 is installed on the lower structure may be arranged in parallel along the road progress direction or may be arranged in parallel along the road width direction.

Since the installation of the lower structure and the H beam 10 is not much different from the conventional installation structure and construction method, the detailed description is omitted, but the present invention basically has a length and bending resistance instead of the conventional perforated plate as a structural member of the upper plate. Since the large sheet pile 20 is used, the installation interval of the H beam 10 can be widened within a range without structural problems.

When the installation of the H beams 10 is completed, the sheet pile 20 is installed on the H beams 10.

The sheet pile 20 has a bottom portion 21, both inclined portions 22 and both wing portions 23 are integrally formed, and the recessed portion blocked by the bottom portion 21 and both inclined portions 22 ( 24).

When the installation of the sheet pile 20 is completed as described above, a paving layer having a predetermined thickness is installed on the sheet pile 20.

The pavement layer 30 first fills the recesses 24 of the sheet piles 20 with a filling material 31 made of sand or foamed styrene resin (also called styropol or styrofoam) up to the lower half (approximately 2/3 height). The filling material 31 and the sheet pile 20 may be constructed by a method of laying a predetermined thickness of the surface layer material 32 made of concrete or asphalt.

Of course, in the practice of the present invention, the pavement layer may be composed of the pavement layer using only the surface material of asphalt or concrete without the use of the filling material, but as described above, the filling material 31 and the surface material ( The reason why the construction is divided into 32) is to make it easy to separate the sheet pile 20 and the packaging layer 30 when dismantling after use of the crosslinking, so that there is no problem due to the foreign matter in reusing the sheet pile.

As described above, the present invention provides a top plate of crosslinking through a method of forming a pavement layer of concrete or the like using a sheet pile as a structural material that receives a dead load or a traffic load of the upper part, and in the present invention According to the following effects.

First, the surface of the top plate is paved with asphalt or concrete, so that the flatness is good and the construction can be performed at the same level without a step difference in construction, thereby providing a comfortable running property to the passing vehicle and promoting smooth traffic communication.

Second, since the slip is prevented and there is no rattling phenomenon, the risk of traffic accidents is eliminated and the driver's anxiety is eliminated, as well as the damage of the passing vehicle is prevented.

Third, as the upper plate is sealed by the whole packing layer, it is possible to ensure a waterproof working environment for the lower space of the upper plate and to maintain a good working environment without pollution, so that the lower work can be performed smoothly, It fundamentally solves the cause of safety accidents, and has the effect of protecting the facilities and machinery under the roof.

Fourth, the cost of construction materials is cheap, the installation is simple, the construction is good, and the air can be shortened significantly, so the construction cost is low.

Fifth, since there is no risk of being damaged or deformed due to no impact when the vehicle passes, it is convenient and economical for long-term maintenance because there is little work to repair.

Sixth, structurally, it becomes a continuous beam type supported by a large number of H beams, which drastically reduces the deflection and vibration after installation and improves the structural stability of temporary bridges. The length can be widened, which greatly reduces the cost of construction.

Seventh, because the pile pile material can be stacked and transported, the material transport and hypothesis has a quick advantage in case of emergency.

Eighth, safety balustrades and additional facilities can be assembled and installed directly on the seat pile, which greatly reduces the overall air and cost.
