JPS62264216A - Assembly of banking-stabilizing anchor for vertical retaining wall - Google Patents

Abstract

PURPOSE:To obtain a banking-stabilizing anchor which can be easily assembled and can simplify the packing of soil by a method in which many trench-forming materials are aligned in a row and bound by supporting bars put on them. CONSTITUTION:Many trench-forming materials 5, each consisting of a web 1 and flanges 2, are aligned in a row by contacting the flanges 2, and the flanges 2 of both ends are combined with reinforcing steel plates 6 on both ends of a supporting bar 9 consisting of the two reinforcing steel plates 6 and a steel bar 8. A covering material 10 is covered on the middle flange 2 and one end of the bar 9 is connected to a vertical retaining wall 12 by bolts. Soil is embedded on the trench-forming materials 5. The assembling work can thus be made easier and the packing operation of soil can be simplified. The efficiency of operations can be raised.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of Japanese Patent Application No. 60-81473 entitled "Method for constructing embankment stabilizing anchors for continuous retaining walls." Special application 60
-81473 requires a long and heavy support rod to pass through the long molded sheet through the dengaku sashimi, which requires space for assembly and requires work while supporting the heavy support rod. In addition, when the molded sheets are laid down and installed, there are places where the surface is covered every other time, so filling those parts with earth and sand requires work from both open sides, which takes time and effort.

The present invention replaces the molded sheet with a channel-shaped member so that the support rod can be mounted from above without having to penetrate it, and by changing the assembly method, it saves space. In addition, soil filling can be performed only from above, improving work efficiency.

Next, the present invention will be explained. First, let's talk about the parts used.

As shown in Figure 1, the length of the web (1) is at least 5 times the height of the flange (2), and the notch (3) for inserting the support rod is made in the center of the top of both flanges. Bolt holes on the left and right (4)
As shown in Fig. 2, there is a threaded groove in the center and bolt holes (5) on the left and right sides.
4) are carved into two reinforcing steel plates (6) with screw grooves (6) on both ends.
Support rods (7) screwed into the carved steel bars (8)
9) and a steel plate or plastic plate with cutouts (3) for inserting support rods on both sides of the rectangle and bolt holes (4) on the left and right sides of the cutouts as shown in Fig. 3. Use the covering material (10) folded in half as shown.

Next, the assembly method will be described step by step.

As shown in Figure 5, a large number of channel-shaped members (
5) are installed in a line with the web facing down and the flanges touching each other.

A small amount of earth and sand (11) is piled up on top of the web of channel members installed as shown in Figure 6. The piled earth and sand stably holds the channel member by its weight, and also serves as a spacer for the support rod (9) installed at a distance from the web.

As shown in Figure 7, the support rod (9) is passed over the notches (3) of the channel members (5) and the earth and sand (11) arranged in a row, and the reinforcing steel plates (6) at both ends of the support rod are attached. , are bolted and fixed to the flanges (2) at both ends of the channel members (5) arranged in a row.

As shown in Figure 8, cover material (1
0) and tie the flange and bolts to the support rod (9)
is surrounded by a flange.

As shown in Figure 9, one end of the support rod (9) is connected to a continuous retaining wall made of concrete (12) or steel plates, and earth and sand (11) are placed on top of the channel members (5) arranged in a row. Embed and pressurize.

This is a construction method for embankment stabilizing anchors for a continuous retaining wall that is constructed by repeating the above operations.

Next, the features of the present invention will be described.

(1) As an anchor, the part that uses resistance force, which requires a thick plate, can be made thick, and the part that uses friction force, which does not require a thick plate, can be made thin, so materials can be used rationally. (2) Part of the buried earth and sand can be , also used for other purposes during work. That is, if a small amount of earth and sand is piled up on top of the web of channel members arranged in a row, the weight of the pile will temporarily hold down the channel members. The piled earth and sand also serves as a spacer for the support rods that are installed at intervals from the web. The small mound of earth and sand is compressed together with the earth and sand that is buried above it, and eventually becomes part of the reclaimed soil.

(3) The flanges at both ends of the channel-shaped members arranged in a row are tied together with bolts to the reinforcing steel plate of the support rod, and the position of the channel-shaped members is fixed. Further, the flanges that are adjacent to each other in the intermediate portion are bolted together with a covering material that is placed over the inserted support rod, and the channel members are fixed to each other.

(4) As in Patent Application No. 60-81473, the support rods are not inserted into the patterned sheet, but are inserted from above into the notches for the support rods in the flange of the grooved material, so the work is natural and quick. can be done. Furthermore, in the patterned sheet of Patent Application No. 60-81473, filling of the covered areas with earth and sand, which is present every other time, is done from both open sides, which requires time and effort, but in the present invention, filling is done from above. It is reasonable because it is a work of

Claims (1)

[Claims] The length of the web is at least 5 times the height of the flanges on both sides, and a notch for inserting a support rod is made in the center of the top of both flanges, and bolt holes are bored on the left and right sides of the notch. A steel plate or plastic plate channel member with a threaded groove in the center and two reinforcing steel plates with bolt holes on the left and right sides of the reinforcing steel plate are each screwed into a steel bar with threaded grooves on both ends. A large number of groove-shaped members are installed on a flat surface using a covering material made of a steel plate or a plastic plate folded in half with bolt holes drilled on the left and right sides of the cut for holding down the support rods. Install them in a row, with each flange touching the bottom. A small amount of earth and sand is then piled onto the web of each channel. A support rod is passed over the notches and earth and sand of the channel members arranged in a row, and the reinforcing steel plates at both ends of the support rod are tied and fixed with bolts to the flanges at both ends of the channel members arranged in a row. After covering each intermediate flange with a covering material and binding the flanges with bolts, connect one end of the support rod to a continuous retaining wall made of concrete or steel plate ■. Earth and sand are buried and compressed on top of the channel members arranged in a row. A construction method for embankment stabilization anchors for vertical retaining walls that is constructed by repeating the above operations.
