Description

Technical Field

[0001] The utility model relates to the field of trench construction structures, in particular to a retaining structure used for trench excavation. Background Art

[0002] In the construction of urban pipe network reconstruction, trench excavation is often involved. During construction, the soil excavated from the trench is often piled on the ground not far from the trench, forming a pile of soil. Since there is no safety protection barrier between the trench and the pile, once the earth and stone or stones in the pile slide into the trench, it will cause personal injury to the workers in the trench, thus causing a safety accident. At present, there is no simple and effective retaining structure. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a retaining structure for trench excavation which can effectively prevent soil piles from sliding into the trench and further protect workers in the trench.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a retaining structure for trench excavation, including a trench in excavation, a mound consisting of soil excavated from the trench is arranged on the ground next to the trench, and includes a retaining plate, the retaining plate includes two baffles, the two baffles are arranged perpendicular to each other to form an L-shaped structure, one of the baffles is arranged on the ground in a horizontal direction and the baffle is arranged at the bottom of the mound, and the retaining plate is arranged between the trench and the mound.

[0005] Furthermore, the side wall of the baffle arranged vertically in the retaining plate is provided with at least one hook for fixing the dustproof net.

[0006] Furthermore, the hook is arranged on the wall surface of the baffle plate facing the groove.

[0007] Furthermore, at least one baffle plate inclined steel bar is arranged between the two baffle plates, and two ends of the baffle plate inclined steel bar are respectively fixedly connected to the two baffle plates.

[0008] Furthermore, it comprises a fence, and the soil pile is arranged between the fence and the retaining plate.

[0009] The beneficial effect of the utility model is that, in actual use, one of the retaining plates is horizontally set on the ground, and then soil is covered on the horizontally set retaining plate to press and fix the retaining plate to prevent the retaining plate from tilting. Afterwards, the newly excavated soil in the trench is normally piled near the aforementioned soil. The continuous flow of soil will only make the horizontally set retaining plate more and more stable, thereby ensuring that the retaining plate set in the vertical direction also obtains a stable supporting force, thereby effectively preventing the soil pile from sliding into the trench, and ensuring the safety of the workers in the trench. The utility model is particularly suitable for trench excavation construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the positional relationship between the enclosure, the earth pile, the retaining plate and the groove of the utility model.

[0011] Figure 2 It is a schematic diagram of the retaining board blocking the soil pile after the soil pile of the utility model presses the retaining board tightly.

[0012] Marked in the figure are: soil pile 1, retaining plate 2, retaining plate inclined steel bars 21, retaining plate 22, hook 23, trench 3, and enclosure 4. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] like Figure 1 , Figure 2 As shown, in actual construction, the soil is first dug out from the trench 3, and the soil is piled in the area formed between the enclosure 4 and the retaining board 2. Among them, it is ensured that the soil pile 1 formed by the soil presses the baffle 22 set horizontally on the ground at the bottom of the retaining board 2, so as to ensure that when the retaining board 2 is subjected to the lateral pressure of the soil pile 1 in the horizontal direction, the baffle 22 in the vertical direction of the retaining board 2 can always be firmly supported, and the retaining board 2 will not be overturned by the above-mentioned lateral pressure. The soil pile 1 here, while pressing the retaining board 2, also allows the retaining board 2 to obtain a stronger supporting force, which in turn supports the soil pile 1. Of course, during actual stacking, it should be ensured that the height of the soil pile 1 should not exceed the height of the baffle 22 set in the vertical direction of the retaining board 2 as much as possible. If the height is too high, try to arrange the highest point of the soil pile 1 toward the side of the enclosure 4.

[0015] As a core component for achieving the earth retaining effect, the earth retaining plate 2 includes two retaining plates 22, which are arranged perpendicular to each other to form an L-shaped structure. Figure 2As shown, the retaining plate 2 with an L-shaped structure is simple to manufacture and can form a mutually supporting force relationship with the soil pile 1, that is, when the soil pile 1 presses the baffle 22 arranged in the horizontal direction in the retaining plate 2, the pressing force will also serve as the supporting force of the baffle 22 arranged in the vertical direction in the retaining plate 2. The supporting force will ensure the stability of the retaining plate 2 when it is subjected to the pressure of the soil pile 1, thereby preventing the retaining plate 2 from flipping to one side of the groove 3.

[0016] In addition, in order to further prevent the soil in the soil pile 1 from being scattered by the wind and thus polluting the construction environment, at least one hook 23 for fixing the dust net can be selected to be provided on the side wall of the baffle 22 arranged in the vertical direction in the retaining plate 2. After the dust net is fixed by the hook, it can effectively prevent the soil from polluting the surrounding area. Generally, the edge of the dust net can be fixed on the hook 23 and the enclosure 4 to form a covering method that completely covers the soil pile 1, effectively protecting the soil pile 1.

[0017] In order to further strengthen the structural strength between the two baffles 22, at least one baffle inclined steel bar 21 may be provided between the two baffles 22, and both ends of the baffle inclined steel bar 21 are respectively fixedly connected to the two baffles 22. A stable triangular force relationship is formed between the baffle inclined steel bar 21 and the two baffles 22, thereby making the overall structure more stable.
