Abstract

The present invention relates to a soil wall temporary construction method using a U-type sheet pile when digging underground to install a structure (F), such as a waterway box, bridge foundation, U-shaped sheet pile (1) is ground (S) or In the case of weathered rock (WR), it is possible to directly enter into the Vibrohammer (VB). However, if soft rock (SR) appears earlier than the planned height (H) of the structure, the U-type sheet pile (1), which is a conventional technology, may be softened (SR). In order to secure the design entry depth (D) by using a water jet (WJ). At this time, the U-shaped sheet pile (1) is weak due to the limitation on the indentation depth (D), structural stability is deteriorated, and the construction efficiency is reduced due to the large amount of construction time, resulting in a large construction cost.

In order to solve the above problems by using the H-shaped thumb pile 40 having a higher rigidity than the U-shaped sheet pile (1), and entering into the hole, by installing a guide iron plate 44 to the H-shaped thumb pile flange 41 A space 46 is secured. At this time, the L-type sheet pile 47 is inserted into the H-shaped thumb pile 40 using the space between the H-shaped thumb pile flange and the guide steel plate, and the flange 41 and the guide steel plate 44 of the H-shaped thumb pile are inserted. It is characterized in that the index member 43 is installed in the space 46.

In the present invention, by installing the guide iron plate on the H-type thumb pile flange to facilitate the connection of the thumb pile and L-type and WU-type sheet pile to improve the workability, the index material in the separation space of the H-type thumb pile flange and the guide iron plate The installation has an excellent ordering effect on the earth walls of the trench temporary facility.

Description

 Installation method of earth wall temporary installation by connecting thumb pile with guide plate and wide sheet piles {Connection method h pile and wide sheet pile}

The present invention relates to a construction method for earth wall construction using a W-U type sheet pile (40) at the time of digging for constructing structures such as a waterway box, a bridge foundation, etc. in a city center and a river with a high groundwater level.

When building or civil works, the ground of the site is excavated to make concrete structures such as the foundation of the building, underground parking lot, underground box (F), and then the structure is constructed. (G) Earthworks shall be made to prevent the collapse of the soil and the penetration of water. At this time, in an area with a lot of water, that is, an area with a high groundwater level (WT), by applying a temporary construction method using a U-shaped sheet pile (1), which is one of the soil barrier construction, to support the earth pressure of the excavation back portion (G) and to prevent water penetration It is.

The construction procedure of the temporary construction method using the U-shaped sheet pile is carried out by digging the U-shaped sheet pile (1), which acts as a support pile, to the indentation depth (D) of 2.0 ~ 3.0M below the planned height (H) of the structure. In order to support the earth pressure on the back and prevent the penetration of water, the U-shaped sheet pile (2) is inserted into the weathered rock (WR) and the U-shaped sheet pile (1) of the support pile and the U-shaped sheet pile (wall) Construct 2,5).

Then, when the inner space surrounded by the sheet pile (1) is completed, excavate the inner space for installing the structure, install the strip (3) and the support material (4) to construct the structure (F) after the completion of excavation, and after the structure is constructed Is made in the order of dismantling the support material (4) and the strip (3) and the U-shaped sheet pile (2) and the U-sheet sheet pile (1) of the support pile.

When the U-sheet sheet pile (1) acting as a support pile emerges earlier than the planned height (H) where the structure (F) is located, the soft rock (SR) of the ground is known as the conventional waterjet (WJ) and vibrohammer. (VB) is used to enter.

At this time, it takes a lot of time when the U-type sheet pile (1) is inserted into the rock with the Vibrohammer (VB), and the damage of the U-type sheet pile (1) due to the long-term vibration and the driving and Uncertainty leads to increased stability of the sheet pile and increased water penetration due to damage, which always implies the risk of collapse of the temporary facility.

In the present invention, in order to solve the above conventional problems, using the H-shaped thumb pile 40 having a higher rigidity than the U-shaped sheet pile 1 serving as a support pile, the indentation (N1) after drilling into a rock drill. .

And in order to make the wall 50 to support the earth pressure of the excavation back surface (G) and prevent the ingress of water, between the support pile H-shaped thumb pile 40 between the LW type 47 and WU type 48 sheet pile To form the wall 50. At this time, the index member 43 and the guide iron plate 44 is installed on the H-shaped thumb pile flange 41.

The comparison of the performance of the U-shaped sheet pile and H-shaped thumb pile and the earth wall forming the supporting pile is shown in Table 1 below.

division Support pile Wall U type sheet pile H-shaped thumb pile U type sheet pile W-U type sheet pile Sectional coefficient (per head) 250 cm 3 1,360 cm 3 250 cm 3 376.9 cm 3 Cross section area 74.4 cm 2 119.8m 2 74.4 cm 2 82.7 cm 2 Sectional Second Moment (per head) 2,790 cm 4 20,400 cm 4 2,790 cm 4 3,055 cm 4 Width (the main hall) 40 cm 30 cm 40 cm 70 cm

In the present invention, the structural stability is improved by using the H-shaped thumb pile 40 having a higher rigidity than the U-shaped sheet pile 1, and the index member 43 and the guide iron plate on the H-shaped thumb pile 40 flange 41. By installing 44 to secure the insertion space LW type 47 and WU type 48 facilitates the connection and disassembly of the sheet pile.

The guide steel plate 44 and the LW type 47 sheet pile are engaged with the H type pile flange flange 41 to secure structural stability superior to that of the conventional sheet pile 1, and the H type pile pile flange 41 is secured. The index member 43 is installed between the guide plate 44 and the guide plate, and the width of the width is wider than that of the conventional U-shaped sheet pile, so that the sheet pile connection portion is smaller, so that the water-repelling effect on the water penetration of the excavation rear portion is excellent.

As described above, H type thumb pile 40 and LW type 47 and WU type 48 sheet piles are integrated to improve stability, and the width of the sheet pile is increased by using a wide width WU type 48 sheet pile. As the construction period is shortened, the construction cost is reduced and structural stability is improved.

The present invention will be described in more detail with reference to the accompanying drawings (Figs. 7, 8 and 9).

(1) The bolts 42 are welded to the H type thumb pile flange 41 at regular intervals and installed.

(2) An attachment type index member 43 is attached to the H type thumb pile flange 41.

(3) In the center of the guide iron plate 44, a punch for fastening the bolts is performed at the same interval as the bolts installed on the thumb pile flange.

(4) While assembling the guide iron plate 44 with the nut 45 on the upper portion of the H-shaped thumb pile flange 41, to secure the space 46 of the H-shaped thumb pile flange and the guide iron plate.

(5) After drilling (N1) with a rock drill, the H-shaped thumb pile produced in (4) is inserted (N2).
