Description

Rapid Construction Structure of Reinforced Earth Retaining Wall Using H Piles}

The present invention relates to a reinforcement earth retaining wall. The existing reinforcement earth retaining wall is a retaining wall that is completed by assembling and rearing the precast front plate or block and commercial reinforcing strips that are manufactured at the factory in advance without placing concrete on the site. As a construction is relatively easy and has a quick advantage. However, the conventional method described above uses a brace material 26 before and after the front plate during construction, in which a plurality of individual front plates 22 are coupled, and temporarily uses the clamp 28 in the coupling between the front plates 22. It is accompanied by the hassle of doing.

Existing reinforcement retaining wall structure is to install the temporary support (26) for the front plate upright in construction, and clamp (28) to hold the individual front plate 22 during the step-by-step construction for secure coupling between the front plate (22) There is a hassle to use. The present invention is to solve the above problems by inserting the front plate in the abdomen of the H-shaped steel pile (42a) or the composite-type H pile (42b) coated with concrete to complete the construction quickly to shorten the air and at the same time For external stability, ie external forces against activity and conduction, H-type steel piles 42a typed on the front of the retaining wall or synthetic H-type steel piles 42b coated with concrete are used to increase the lateral resistance of the ground inlet. Higher safety than reinforced retaining wall can be achieved.

The present invention is to propose a prefabricated reinforced soil retaining wall structure using the H pile improved in the construction period as compared to the existing reinforced earth retaining wall structure as described below with reference to the drawings.

First, as shown in FIG. 4a, a hole 32 is drilled in the H-shaped steel 30 and the reinforcement ring is made by the U-shaped bolt 34 and the nut or welding, or the U-shaped bolt is connected as shown in FIG. 4B. The H-shaped steel 30 is coated with concrete 36 except for the connection part so as to be connected with the reinforcement, but the lower part which is typed in the ground is not coated to maintain the driving penetration. The concave connection portion of the concrete-coated H-shaped steel is made of concrete composite H-shaped steel pile 42b so that the horizontal bar of the U-shaped bolt is located in the concave portion so that the ground reinforcement can be connected to the flange portion of the H-shaped steel. In addition, the panel-type faceplate is a rectangular shape longer than the conventional faceplate as shown in FIG. 5 and the reinforcement is connected to the horizontal rod as shown in FIG. Install the concave connecting rod 40 so that it is manufactured to be convenient when carrying and loading. The front panel has one jaw for the uppermost part 44a, the middle part 44b, and the lowermost part 44c, and is manufactured in a simple type (Fig. 5a) to resist movement between the upper and lower panels. ), The middle (46b), the bottom (46c) as the concave-convex type (Fig. 5b), the panel is engaged with the front and back and left and right so that there is no movement of up, down, left and right, the abdomen (38) The panel-type faceplates 44 and 46 are inserted into the structure. In order to complete the reinforced earth retaining wall structure of the present invention, first, H-shaped steel piles (Fig. 7a) or concrete composite H-shaped steel piles (Fig. 7b), that is H-shaped steel piles at a predetermined interval on the arranged construction surface After type, the precast panel-type faceplates 44 and 46 are inserted into the abdomen 38 of the typed pile, as shown in FIG. 8, and then the reinforcement 24 is concave connection portion 40 and the pile of the panel-type faceplate. It is connected to the c-shaped connecting portion 34 of the rear soil. By inserting the front plate on the abdomen of the H-beam, it is possible to reduce the hassle and construction period to maintain the upright of the front plate by installing the clamp on the front and the H-beam pile into the ground, It can also contribute to stability. By repeating the above process step by step to complete the reinforced soil retaining wall structure 48 using the H-shaped steel pile and the ground reinforcement as shown in FIG.

Reinforced soil retaining wall structure using H-beam pile or concrete composite H-beam pile of the present design eliminates the hassle of installing braces and clamps during construction to maintain the upright face of existing reinforced soil retaining wall, and H-beam pile or concrete composite Simplify the installation of the front plate easily using H-shaped steel piles, and improve the workability by using the rectangular panel type faceplate which has a larger area than the face plate of the existing reinforced earth retaining wall. An improved effect can be expected on stability, ie safety on activity and conduction.
