Abstract
Description
Culvert that controls the behavior of PC culvert objects of civil drainage structures with cohesive force
In the case of PC culvert among civil drainage structures, after surveying the construction, the inter-locking ability of the culvert itself is not limited to the connection force between the objects by using the steel wire or some steel wire which is extremely small compared to the volume and weight of the PC culvert. It acts only on very small or pure vertical loads, but it is also very small displacement, ground subsidence, lateral flow during backfilling, reloading of loads, and so on. Is causing major problems.
1. In order to improve this, it is necessary to make interlocking protrusions when connecting PC culvert objects and to provide interlocking resistance in all directions.
2. When assembling a PC culvert, it should be able to secure the taste resistance as much as it resists deformation without additional tension binding force.
3. When assembling the PC culvert, the guide rail necessary for the assembly is necessary to assemble it with precision, and it must not be pushed by the movement of the culvert during assembly, and this tool must be integrated with the culvert against settlement after assembly.
4. After assembling the PC culvert, it is necessary to increase the adhesive strength to the joint and waterproof measures against watertightness.
5. When assembling the PC culvert, there is a need for a tool to close the two PC culverts together with a simple tool without the need for additional equipment, and it must act as a resistance against deformation after assembly.
1.In case of unequal settlement and movement of connection part due to settlement of ground, side flow, reloading of loading load, etc. after PC culvert installation, adjacent culverts should have a binding force to move integrally.
The restraint force is to be controlled up, down, left and right, and when vertical or lateral loads are applied, they should not be transferred to inclined loads or front and back loads to push the culverts.
2. The binding force must inevitably be binding so that no medal can be hit in the air without bottom.
3. When connecting, install guide rails to guide the culvert horizontally, but the connected guide rails should not be separated from each other about the movement of the culvert.
4. It is difficult to secure the watertightness of the culvert without any additional treatment. Therefore, the adhesion between the culvert should be increased while securing the watertightness of the culvert and the culvert.
5. When connecting culverts and culverts, tools are required to be joined to each other. They shall exert tensile force after connection and resist deformation of the culvert joints.
1. Deeply create the unevenness that engages the front and back of the culvert to control the culvert from escaping up, down, left and right.
2. The irregularities protrude enough to withstand the load of the culvert and have sufficient thickness.
3. Guide rails should be made with sufficient rigidity so that the front and rear rails do not cross each other.
4. Make grooves on the front and back uneven parts and assemble grout and inject grouting liquid.
5. Make a groove in the culvert, attach the reinforcing steel plate to the grooves of the front and rear culverts, and then tighten the front and rear culverts with bolts and nuts.
1. The front and rear of the culverts are made of up and down, left and right to interlock with each other (under-locking) to prevent deformation of the culvert without any additional materials, and artificially giving 100% horizontal force without detachment Are not separated unless the culvert is destroyed.
2. Install the separation prevention type guide rail on the lower corner to facilitate the installation of the culvert.
3. Make a groove in the center of the front and rear joints of the culvert and inject grouting liquid after assembly to induce adhesion of the culvert and secure watertightness.
4. Make grooves for fixing the reinforcement plate and bolt nut on the side of the culvert and assemble the pc culvert using the bolt nut.
This is a drawing of 3 sets of interlocking culverts, the core of this research project.

1. Deeply create the unevenness that engages the front and back of the culvert to control the culvert from escaping up, down, left and right, and maintain the 90 degree angle with the uneven part and the cross section to maximize the engagement. In addition, the concave-convex portion maintains the thickness of the deformed portion so that the concave-convex portion is not broken by the interlocking pressure.
2. The guide rail shall be manufactured to have sufficient rigidity, and the rails at the front and rear shall not interlock with each other as shown in the drawings, and the connecting part shall be located at the center of the pore culvert to control the departure of the rail by the load of the pore culvert. To help.
3. Make grooves in the center of the front and back irregularities and assemble culvert and inject grouting liquid. The groove is installed so that the injection and the outlet can be easily distinguished, and the groove has a predetermined diameter so that the grouting injection liquid is sufficiently injected, but is installed so as not to reduce the strength of the unevenness. After assembling, grouting not only ensures the watertightness of the joints, but also improves the adhesion of the front and rear culverts and prevents stress concentrations in the voids by filling the voids in the joints.
5. By making a groove in the culvert and attaching a reinforcing steel plate to the grooves of the front and rear culverts, the front and rear culverts are tensioned and joined by bolts and nuts to facilitate the assembly of objects and to control the coupling per segment. Prevents and assists in preventing culvert deformation.
