Problems solved by technology

[0002] At present, the temporary roads on the construction site of construction projects are all constructed in the way of plain concrete or reinforced concrete with a thickness of 120 mm ~ 200 mm. The disadvantage is that the process There are many processes, such as transportation of steel bars, concrete materials, formwork support, on-site pouring of concrete, and on-site finishing, which require a lot of labor, machinery, and materials; in addition, this cast-in-place temporary road is After on-site construction, on-site maintenance is required, and on-site temperature joints must be cut after maintenance, which has a certain impact on the construction period benefit and economic effect-resulting in a large increase in cost; moreover, because the on-site construction temporary road is not a centralized module stereotyped production , the quality of the finished temporary roads on site cannot be guaranteed, such as uneven road surfaces, sandy road surfaces and other quality problems; finally, after the project is completed, because the temporary roads are cast-in-place roads, they cannot be turned around and can only be discarded or destroyed. And it needs to be cleaned manually and mechanically, which will incur a certain cost, which is a waste and pollution of resources and the environment.

Embodiment 1

[0025] see figure 1 , a temporary road embankment block that can be turned around, consisting of a base block 1, a long-side connecting socket 2, a short-side connecting socket 3, a hook 4, a limiting block 5 and a limiting angle steel assembly 6; wherein, see image 3 , the short-side connection socket 3 is a steel bar folded into a C shape, and the two ends of the short-side connection socket 3 are fixedly connected with a limit block 5 respectively; see image 3 , the long-side connection socket 2 is a steel bar folded into a C shape, and the two ends of the long-side connection socket 2 are fixedly connected with a limit block 5 respectively; see figure 2 , the hook piece 4 is a steel bar folded into an L shape, and the end of the long rod side of the hook piece 4 is fixedly connected with a limit block 5; see Figure 5 and Image 6 , the limit block 5 is a cylinder; the diameter of the limit block 5 is greater than the diameter of the steel bars that form the long-si...

Embodiment 2

[0029] Whole structure is with embodiment 1. In addition, an edge protection angle steel assembly 8 is also provided. The edge protection angle steel assembly 8 is composed of four angle steels fixedly connected to each other. when the top of the base block 1) or set on the top of the base block 1 (when the limit angle steel assembly 6 is hooped on the bottom of the base block 1), see Figure 7 . That is, the limit block 5 connecting the hook piece 4, the long-side connection socket 2 and the short-side connection socket 3 through the limit angle steel assembly 6 is restricted to expand and contract in the corresponding blind hole 7, and is protected by the edge protection angle steel assembly 8. The edge of substrate 1, such as Figure 8 shown.

Embodiment 3

[0031] Whole structure is with embodiment 1. In addition, an edge protection angle steel assembly 8 is also provided. The edge protection angle steel assembly 8 is composed of four angle steels fixedly connected to each other. when the top of the base block 1) or set on the top of the base block 1 (when the limit angle steel assembly 6 is hooped on the bottom of the base block 1), see Figure 9 . Wherein, the height H3 of the vertical edge of the edge protection angle steel assembly 8 is greater than the shortest distance H4 from the horizontal edge of the edge protection angle steel assembly 8 to the edge of the blind hole 7, as shown in Figure 19; that is, through the limit angle steel assembly 6 and the edge protection angle steel assembly 8 each of the four vertical sides half-closes the opening end of each blind hole 7 on the base body 1, so that the stopper 5 connected to the hook 4, the long-side connection socket 2 or the short-side connection socket 3 is closed. Limit...

Abstract

The invention provides a recyclable temporary road subgrade block, aiming at overcoming the defects of the existing cast-in-place concrete way used for temporary roads in a construction site. The temporary road subgrade block comprises a base block, a long-side connection faucet piece, a short-side connection faucet piece, hook pieces, limited blocks and limited angle steel components. The temporary road subgrade block has the beneficial effects that the subgrade block can meet the use requirement of a temporary road of a site, and meanwhile does not require any other materials, is simple to manufacture and convenient to assemble, can be recycled for multiple times, is applicable to all temporary roads in constructional engineering sites, is simple in structure, safe, reliable, and flexible in arrangement, can save a large amount of concrete material cost and measure expense, and can shorten the construction period.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a revolvable temporary road subgrade block used at the engineering site. Background technique [0002] At present, the temporary roads on the construction site of construction projects are constructed in the way of plain concrete or reinforced concrete with a thickness of 120 mm ~ 200 mm. A series of processes such as on-site pouring of concrete and on-site lightening require a lot of labor, machinery, and materials; in addition, this kind of cast-in-place temporary road needs on-site maintenance after on-site construction, and on-site temperature cutting is required after maintenance. Seams have a certain impact on the benefit of the construction period and the economic effect - resulting in a large increase in cost; moreover, because the temporary roads on site are not produced in centralized modules and finalized, the quality of the finished temporary roads on site cannot ...
