The further optimized technical scheme is that the weight block body is a concrete precast block.
The pile covering film weight block adopts the following technical scheme:
the pile body covering film weight block comprises a strip-shaped weight block body which is used for being pressed and fixed on a pile body platform covering film and extends along the edge length direction of a pile body platform, hook positioning grooves for vertically clamping and hooking rope hooks are arranged on the right side face of the weight block body at intervals along the length direction, the hook positioning grooves are L-shaped on the vertical section of the weight block body, the vertical section of the L-shaped vertically penetrates through the weight block body up and down, the transverse section is positioned on the bottom face of the weight block body and extends leftwards for setting the length for being matched with the hook ends of the rope hooks, and when the pile body covering film weight block is used, the bottom face of the hook ends of the rope hooks do not protrude out of the bottom face of the weight block body.
The technical scheme of further optimization is that the vertical section of the weight block body is rectangular, and the upper right corner of the vertical section is an arc-shaped anti-cutting angle.
The further optimized technical scheme is that the arc-shaped anti-cutting angle is arc-shaped.
The further optimized technical scheme is that the weight block body is a concrete precast block.
The beneficial effects of the utility model are as follows: the pile body platform is provided with the strip-shaped pressing block for pressing and fixing the covering film, and the pressing block is provided with the hook positioning groove, so that a rope can be used for fixing weight blocks such as sand bags and tires used for pressing and fixing the covering film of the side slope on the pile body side slope; in addition, the rope hook is hooked in the positioning groove by arranging the hook positioning groove, so that on one hand, sand bag tires on a side slope can be paved at fixed distance on a construction site, and on the other hand, the rope hook can be prevented from sliding, and the stability of the hook and the rope and the firmness of pressing and fixing are guaranteed; moreover, the bottom surface of the hook end of the rope hook does not protrude out of the bottom surface of the weight block body, so that the hook end of the rope hook can not contact the covering film in a normal matching state of the rope hook and the weight block after construction is completed, the hook end of the hook is prevented from pressing the covering film, and the covering film is ensured to cover the pile body perfectly.

In the figure, 1 is a weight block body, 11 is a vertical section of a hook positioning groove, 12 is a transverse section of the hook positioning groove, 2 is a rope hook, 3 is a rope, 4 is a weight block, 5 is a fly ash stack, 51 is a stack slope, 52 is a stack platform, and 6 is a cover film.
Description of the embodiments
An embodiment of the stack covering film weight block is shown in fig. 1 to 3, the weight block comprises an elongated weight block body 1, hook positioning grooves are formed in the right side face of the weight block body at intervals along the length direction, the hook positioning grooves are L-shaped on the vertical section of the weight block body, an L-shaped vertical section 11 penetrates through the weight block body up and down, a transverse section 12 is located on the bottom face of the weight block body and extends leftwards for a set length to be matched with the hook end of a rope hook 2, and therefore firm hooking connection can be ensured. When in use, the weight block is pressed and fixed on the covering film 6 on the pile body platform 52 and extends along the length direction of the edge of the pile body platform, each hook positioning groove is vertically clamped into the corresponding rope hook 2, and the hook end of the rope hook extends into the transverse section 12 of the L-shaped groove and hooks the weight block body 1; the ropes 3 are in one-to-one correspondence with the rope hooks 2, the ropes 3 are connected to the rope hooks from the left side of the weight block, and when the height of the transverse section of the hook positioning groove is set, the bottom surface of the hook end does not protrude out of the bottom surface of the weight block body after the rope hooks are hooked, so that a slope covering film is prevented from being pressed in the use process.
In the concrete implementation, the weight block is preferably a concrete precast block, so that the industrial production is easy, the manufacturing cost is low, the popularization and the application are convenient, the vertical section of the weight block body 1 is also preferably rectangular, at the moment, in order to prevent the ropes from being cut by the rectangular edges, the right upper corner on the vertical section of the ropes is an arc-shaped anti-cutting angle, and the arc-shaped angle is preferably adopted, so that the top surface and the left side surface of the rectangle can be smoothly connected.
An embodiment of the fly ash landfill mulch film pressing device is shown in fig. 1 to 3, and the structure comprises a weight block, a rope 3, a rope hook 2 and a weight block 4, wherein the weight block is the same as the structure of the pile mulch film pressing block in the embodiment, and the weight block is not repeated.
In fig. 1, the pressing block is pressed and fixed on the covering film 6 on the fly ash stack platform 52, and continuously extends along the length direction of the edge of the stack platform, and the pressing block can be manufactured on site, or can be prefabricated into prefabricated unit modules with certain length and convenient transportation in advance, and then spliced on site to form the fly ash stack; the rope hook 2 is vertically clamped into a hook positioning groove, the hook end of the hook is hooked in the transverse section of the positioning groove, and the bottom surface of the hook end of the rope hook does not protrude out of the bottom surface of the weight body 1; one end of the rope 3 is fixedly connected to the rope hook, the other end of the rope extends downwards along the pile slope 51 from the left side of the weight block, and the weight block 4 such as a sand bag tire is fixed by the rope and pressed on the cover film 6 on the pile slope 51. The film pressing device not only can firmly press and fix the cover film of the pile body, but also can well prevent the cover film from being blown up by strong wind to expose the pile body, and can also avoid the rope hook from pressing against the slope cover film, thereby ensuring that the cover film can well seal the pile body.
