The vertical supports 22 are connected to the top of the horizontal support 21 and are fitted to both sides of the retaining wall panel 1. When the prefabricated living area retaining wall is installed, soil is filled at the top of the horizontal support 21 and at the two sides of the retaining wall panel 1, and the retaining wall panel 1 can be prevented from tilting by using the F-shaped support formed by the horizontal support 21 and the vertical support 22. The horizontal support 21 and the vertical support 22 may be plate-shaped structures, channel steel, i-steel, H-steel or C-steel. The length of the vertical support 22 is 1/3 to 1/2 of the length of the horizontal support 21.
In a more preferred embodiment, both the horizontal support 21 and the vertical support 22 are channel steel. The ends of the vertical supports 22 are welded to the web of the horizontal support 21. When the prefabricated living area retaining wall is installed, soil is filled at the top of the web plate of the horizontal support 21 and the two sides of the retaining wall panel 1, and the weight of soil is utilized to press the top of the web plate of the horizontal support 21, so that the stability of the panel fixing frame is ensured. When welding the vertical support 22, the joint type of the vertical support 22 and the horizontal support 21 adopts a T-shaped welding head. The weld grade adopts a secondary weld.
In a more preferred embodiment, a side, away from the retaining wall panel 1, of the bottom of the vertical support 22 is fitted with a horizontal limit clip 3, two ends of the horizontal limit clip 3 prop against the inner side of a flange plate of the horizontal support 21, and a side flange plate of the vertical support 22 is fitted with the horizontal limit clip 3. The horizontal limiting clamp 3 is used for reinforcing the bearing capacity of the vertical support 22. Specifically, the horizontal limiting clamp 3 is made of round steel, two ends of the horizontal limiting clamp 3 are welded with the inner sides of the flange plates of the horizontal support 21, and the horizontal limiting clamp 3 is welded with the outer walls of one side of the flange plates of the vertical support 22.
In a more preferred embodiment, the end of the horizontal support 21 close to the wall surface is provided with the anchor bolts 4 in a fitting manner, and the depth of the anchor bolts 4 into the soil is not less than 500mm. It will be appreciated that in the cross section of the retaining wall, the location of direct contact with the supported soil mass is referred to as the back of the wall; the area opposite to the back of the wall, which is empty, is called the wall surface. Specifically, a nut is welded at one end of the horizontal support 21 close to the wall surface, the bottom end of the foundation bolt 4 penetrates through the nut, and the top of the foundation bolt 4 is in threaded connection with the nut. In addition, round steel with nuts can be selected as the foundation bolts 4, when the foundation bolts 4 are installed, the foundation bolts 4 are tightly attached to one end of the horizontal support 21, which is close to the wall surface, the foundation bolts 4 are driven into soil, and then the nuts are screwed. By providing the anchor bolts 4, the soil body can be prevented from pushing the horizontal support 21 to displace.

The method for measuring paying-off comprises the following steps: according to the coordinate points and the interval dimension of the F-shaped brackets, the outer edge of the retaining wall panel 1 to be installed is scattered with lime to form a through long line, and then the position of the F-shaped brackets is marked on site according to a drawing. And (3) at the starting position of backfill, standing a standard height, and timely observing the backfill elevation during backfilling.
The manufacturing method of the F-shaped bracket comprises the following steps: the flange plate of the horizontal support 21 faces upwards, the bottom end of the vertical support 22 is welded with the inner side of the web plate of the horizontal support 21, and a T-shaped welding head is adopted in the joint type. The weld grade adopts a secondary weld. The spacing between the two vertical supports 22 is slightly greater than the thickness of the retaining wall panel 1. And a horizontal limit clamp 3 is welded between the inner sides of the flange plates of the horizontal support 21 and the outer sides of the flange plates of the vertical support 22, which are far away from the retaining wall panel 1.
The F-shaped bracket is installed by the following steps: the F-shaped brackets are placed along the width direction of the retaining wall panel 1, and the F-shaped brackets are 250mm from the outer edge of the retaining wall panel 1. After the position is fixed, the foundation bolt 4 is arranged at one end of the horizontal support 21 close to the wall surface, and the depth of the foundation bolt 4 entering the soil is not less than 500mm.
The method for installing the retaining wall panel 1 comprises the following steps: before the retaining wall panel 1 is hung, the safety and reliability of auxiliary tools such as hoisting equipment, hoisting machinery, steel wire ropes, rope clamps and the like are checked. Before hoisting, all constructors participating in hoisting must be subjected to safe bottom crossing. And a police ring line is pulled at the position 5m outside the hoisting radius, and a special person is dispatched to take care, so that an irrelevant person can strictly enter. After all preparation works are finished, the retaining wall panel 1 is lifted 200mm away from the ground, and the braking performance and the mechanical stability of the equipment are checked. After the test hanging is confirmed to be correct, the hoisting installation can be carried out. When the retaining wall panel 1 approaches to the F-shaped bracket, two workers straighten the retaining wall panel 1, slowly put down along the vertical support 22, and the steel wire rope can not be completely loosened when the retaining wall panel is put to the horizontal support 21, at the moment, the quick soil filling and rolling are needed, and after the F-shaped bracket and the retaining wall panel 1 are stabilized, the steel wire rope can be loosened, and the downward construction can be continued.
During backfill, the cooperation construction of backfill and retaining wall panel 1, because about 2.5 tons of dead weight of a retaining wall panel 1 prevents to topple over to one side when inserting retaining wall panel 1, need to utilize the dead weight of soil to push down horizontal support 21, when filling to 1m height, reaches the releasable hoist and mount rope of force balance side.
Specifically, taking a prefabricated living area retaining wall as an example, the thickness of the retaining wall panel 1 is 160mm, and the width is 3000mm. The horizontal support 21 is a 1710mm long 30# channel steel, the vertical supports 22 are 650mm long 30# channel steel, the distance between the two vertical supports 22 is 180mm, and the horizontal limiting clamp 3 is phi 20 round steel.
