Description

Temporary earth shelter and permanent self-supporting retaining wall system}

The present invention relates to a self-supporting retaining wall system that doubles as a temporary earth retaining facility. More specifically, it can be used as a retaining wall during construction and as a permanent retaining wall after a concrete composite wall, and can effectively improve the displacement of the H beam due to the pressure of the back soil. This is about a self-supporting retaining wall system that doubles as a temporary earth retaining facility.

Typically, temporary earth retaining facilities are installed at construction sites or civil engineering sites for the purpose of preventing soil collapse, and the temporary earth retaining facilities include earth retaining walls that support the rear soil. Construction methods using H beams and earth plates are common for the earth retaining walls.

In this method, H-beams are inserted into some or all of the pile holes pre-excavated in the ground, concrete mortar is poured into the pile holes to build foundation supports, and earth plates are inserted between the foundation pillars by the H-beams to form a protective wall. However, as the retaining wall gets higher, serious displacement occurs in the H-beams due to the load of the back soil, leading to a major accident.

Accordingly, in the previously disclosed patent registration number 10-2002059, piles are arranged adjacent to each other at intervals, the lower part of which is inserted into the ground hole, and the upper exposed part protrudes above the ground surface; Reinforcement is installed on the back of each of the piles, and extends a certain length from the top of the exposed portion downward along the pile to have a lower reinforcement portion inserted into the insertion hole and an upper reinforcement portion protruding above the ground surface to reinforce the pile. with frames; Earth plates installed to block exposed portions of the piles adjacent to the back of the reinforcing frames to support the back soil; It includes tension force introduction units that introduce tension force backwards to the exposed portions of the piles to prevent forward displacement of the exposed portions due to the load of the back soil, and each of the reinforcement frames is disposed in a vertical direction at the rear of the piles. a vertical reinforcing member that is spaced apart from the pile to form a space between the pile and has a lower region and an upper region respectively corresponding to the lower reinforcing portion and the upper reinforcing portion; A technology including horizontal reinforcing members disposed in a horizontal direction in the space between the pile and the vertical reinforcing member and connecting the vertical reinforcing member to the back of the pile while being spaced apart from each other up and down has been previously proposed.

However, the prior art is intended to prevent forward displacement due to earth pressure and prevent the temporary earth retaining facility from collapsing even if it is installed high without a separate supporting structure. However, the ground is first excavated to a depth where the steel wires at the highest height are exposed, and the highest After completing the anchoring of the tensile end of the high steel wire and the installation of the earth plate, the steps of secondary excavation of the ground and anchoring the tensile end of the exposed steel wire must be repeatedly performed, which reduces on-site constructability and delays the construction period. In particular, Even if the tension end of the steel wire was fixed, there was a problem in that the pile displacement reinforcement capacity was not significantly improved.

The crossbar 610 is provided so that its position is corrected by the plane setting module 800 and its position is fixed by the lock module 900,
The lock module 900 is,
A rock bolt 910 installed on the wedge block 830, with a lock nut 912 screwed to one end, and disposed in parallel with the long bolt 820,
A rock block 920 that is inserted into the rock bolt 910, is transported straight in the longitudinal direction of the rock bolt 910 by the lock nut 912, and has an outer slope 922 symmetrical to the inner slope 832 at one end. class,
A long rail 930 formed on the rock block 920 and parallel to the rock bolt 910,
It includes a rail pin 940 protruding from the wedge block 830 to engage with the long rail 930,
As the wedge block 830 enters between the cross bar 610 and the flange 101 by the pitch transfer of the long bolt 820, the inner inclined surface 832 slides with the inner surface of the flange 101 to position the cross bar 610. After is adjusted, the lock block 920 is transferred by the fastening force of the lock nut 912 and the outer slope 922 is attached to the outer surface of the flange 101, and the flange is formed between the inner slope 832 and the outer slope 922. (101) A self-supporting retaining wall system used as a temporary earth retaining facility, characterized in that it is provided to be restrained.
