Description

Permanent soil barrier walls supporting civil engineering and building

The present invention relates to a permanent retaining wall for supporting civil and building loads, and more particularly, there is no need to provide a plurality of left and right movable support plates according to the thickness of the upper horizontal belt, and distortion and horizontal maintenance between the upper horizontal belt and the lower horizontal belt. There is no need to provide a longitudinal load support piece and an anchor fastening head for It relates to a civil and construction load-bearing permanent retaining wall that can support a wale in a simple yet structurally stable manner.

In order to ensure structural stability, retaining walls generally used in civil engineering and construction are horizontally constructed in addition to vertical H-shaped steel thumb piles and horizontal H-shaped steel wales, which are constructed at intervals of 1.2m to 2.0m to withstand loads such as ground pressure. It is a structure constructed by connecting a number of reinforcing bars inside the rear of the H-beam wale.

In this conventional permanent retaining wall structure, the retaining wall structure includes several vertical H-shaped steel thumb piles 10 that are inserted and buried in the original ground soil 90, and the thumb piles 10 are vertically embedded in the soil at regular intervals. A plurality of earth retaining earth plates 20 that are fitted between the inner sides of the thumb piles 10 in the state to prevent the outflow of soil to the front, and a plurality of metal materials whose rear surfaces are welded and fixed to one side of the front side of the thumb piles 10 A spacer member 39, a horizontal H-shaped steel wale 30 in which one rear side is welded and fixed to the front surface of the spacer 39, and two wales 30 adjacently spaced apart at a predetermined interval, one front side A pedestal 40 in which an earth anchor 46 which is welded and fixed to the ground and is inserted and fixed in the ground soil 90 is inserted through a reinforcing material insertion hole (not shown) through one side, and the spacing member 39 It is configured to include a plurality of reinforcing reinforcing bars (98) spaced apart from the reinforcing bar reinforcement space (T) and the wale (30) is welded jointly fixed to the front part. Then, the pouring pedestal 40, the spacing member 39, the band 30, the reinforcing bar 98, etc. are wrapped around the concrete to prevent corrosion and not collapse, and the concrete is poured and cured with the concrete cement 96.

The spacing of the reinforcing reinforcing reinforcement space portion T spaced apart by the spacing member 39 is inserted and buried in the original ground soil 90, and the thumb pile 10 made of H-shaped steel exposed to soil moisture is corroded and the earth pressure Since the possibility of safety accidents such as collapse due to the load is high, a plurality of reinforcing reinforcing bars 98 must be spaced apart from each other at intervals capable of reinforcing work. That is, in addition to the vertical H-shaped steel thumb pile 10 and the horizontal H-shaped steel wale 30, the reinforcing reinforcement space part inside the rear of the wale 30 to withstand loads such as earth pressure in order to secure structural stability as a permanent structure. It is a structure in which a plurality of reinforcing reinforcing bars 98 are welded and fixed to (T).

As described above, since the thumb pile 10 is inserted and buried in a state where it is exposed to the moisture of the soil as it is, corrosion proceeds, and in addition to the thumb pile 10 and the wale 30, the reinforcing reinforcement space part inside the rear of the wale 30 In addition to (T), since a plurality of reinforcing bars 98 must be fixed by welding joint joints, the material cost of the reinforcing rebar 98 is added, which increases the construction cost and takes a lot of construction time. In addition, since an installation work space for the reinforcement of the reinforcing bar 98 is required, there is a structural engineering problem in that the thickness of the permanent retaining wall structure is increased and a large building area is required.

In order to solve this conventional problem, "In order to prevent corrosion by moisture of the original soil 900, the H-beam body 101 except for the wale joint exposed surface 102 on the front of the wall part 110 is completely in the ground. An anti-corrosion gap maintaining layer 103 of a predetermined thickness (D1, D2) is integrally wrapped around the buried root portion 120 as a whole, and a sealing coating is formed, perpendicular to the perforated hole drilled at regular intervals on the boundary line of the permanent retainer of the original ground Thumb stakes 100 for preventing corrosion, which are inserted and buried with a gap-maintaining thumb stake 100, and the gap-maintaining thumb stakes 100 exposed to the front by excavating the retaining wall in a state in which the gap-maintaining thumb stakes 100 are vertically buried at regular intervals. A retaining earth plate 200 that is fitted between the inner side of the liver to prevent soil outflow, and a beam holder 360 on the wale joint exposed surface 102 of the wall part 110 of the gap maintaining thumb pile 100 is supported by A pedestal 400 on which a reinforcement 460 fixed in the original ground and soil 900 is inserted and fixed; A permanent retaining wall structure equipped with a gap-maintaining thumb pile for corrosion prevention, characterized in that it is installed including including." was disclosed as Patent Registration No. 10-2029040 (announced on April 15, 2011).

In addition, "a number of thumb piles 1a vertically buried at regular intervals in the original soil 9a; and the thumb piles 1a are inserted between the inside of the thumb piles 1a exposed in the front by excavating the retaining wall. A retaining earth plate (2) that is fixed to prevent soil outflow; , an upper horizontal wale (4a) spaced apart from the upper part of the lower horizontal wale (4b) at regular intervals; It is inserted and mounted inside between the upper and lower horizontal wales 4a and 4b so as to fit, and has a height corresponding to the interval between the inner middle partitions of the upper horizontal wale 4a and the lower horizontal wale 4b and has a front face in the width direction A pair of longitudinal support plates 12 that face-to-face both sides of the rear surface of the left and right movable support plate 20, and the upper and lower inner surfaces of the pair of longitudinal support plates 12, in which protrusions protruding in the shape of 'ㅓ' in the center A longitudinal and transverse load support piece (10) comprising a transverse support plate (14) that is fitted and fixed by welding to improve load distribution and support capacity; The anchor fastening head binding hole 22 is installed in the front central opening of the piece 10 to be slidably assembled and installed, and the anchor 6 fixed in the ground soil 9a is the anchor fastening head binding hole 22. The exposed end of the anchor 6 exposed in the front of the anchor fastening head binding hole 22 of the left and right moving support plate 20 is in a straight line in the anchor fastening hole 36 Anchor fastening head 30 that is assembled and installed while adjusting the position up and down along the anchor fastening head binding hole 22 of the left and right movable support plate 20 so as to be inserted and fastened; Retaining wall." With this patent registration No. 10-1534058 (2015.07.06. Announcement) had been initiated

However, this conventional permanent retaining wall reduces the thickness of the concrete cover and can move easily from side to side, while the left and right moving support plate 20 that varies the spacing of the hook 24 according to the thickness of the upper horizontal band 4a. A plurality of separately provided, longitudinal load support pieces 10 and anchor fastening heads 30 must be provided for twisting and horizontal maintenance between the upper horizontal belt length 4a and the lower horizontal belt length 4b. There was a problem in construction that the work efficiency was greatly reduced due to the increase in cost and construction time.
