Technical Field

[0001] The utility model relates to the technical field of culvert construction, in particular to a structure for applying foamed light soil to the backfill of a culvert. Background Technique

[0002] A culvert refers to a drainage passage built under the roadbed and below the road surface in highway engineering construction to enable the road to pass through a water channel smoothly without hindering traffic, allowing water to flow under the road through this structure. During the construction of a culvert, foamed cement light soil is usually used for backfilling the culvert back, so a structure for applying foamed light soil to the backfill of a culvert is required.

[0003] The traditional culvert backfill structure has the advantages of simple structure and convenient operation, but there are still deficiencies.

[0004] During the filling process of the traditional culvert backfill structure, due to its long construction period, the filled soil is prone to loss during the construction period. Content of the Utility Model

[0005] The purpose of the utility model is to provide a structure for applying foamed light soil to the backfill of a culvert to solve the problem of long construction period and easy loss of soil quality mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A structure for applying foamed light soil to the backfill of a culvert, including a soil layer, and further including a layered structure and a covering structure;

[0007] On both sides of the top of the soil layer, culvert side walls are installed, and a culvert top is installed at the top of the culvert side walls. The covering structures are located at the front and rear ends of the culvert side walls;

[0008] The layered structure is located on the side where the culvert side walls are far away from each other;

[0009] The layered structure includes supporting high walls, which are installed on the sides where the culvert side walls are far away from each other. At the bottom ends of the front and rear ends on the sides where the culvert side walls are far away from each other, supporting low walls are installed. At one end of the supporting high walls close to the supporting low walls, a plurality of partition walls are installed. Between the supporting high walls and at the top of the culvert top, filling soil is filled. Between the supporting low walls and the supporting high walls, foamed light soil bodies are filled.

[0010] Preferably, the bottom ends of the supporting high walls extend to the top of the soil layer, and the bottom ends of the supporting high walls are installed on the top of the soil layer.

[0011] Preferably, the partition walls are in an inclined state, and the bottom ends of the partition walls are installed on the top of the soil layer.

[0012] Preferably, one end of the partition wall close to the supporting low wall extends to one end of the supporting low wall, and the partition walls are all installed at one end of the supporting low wall.

[0013] Preferably, the covering structure includes a covering film, a mounting roller, a torsion spring, a mounting plate and a rotating rod. The mounting plates are installed at the upper and lower ends of the mutually remote ends of the culvert side walls, and the rotating rods are installed between the mounting plates through rotating shafts. Mounting rollers are installed on the outer walls of the rotating rods, the covering film is wound around the outer walls of the mounting rollers, and torsion springs are sleeved on the outer walls of the rotating rods between the mounting rollers and the mounting plates.

[0014] Preferably, the torsion springs are fixedly installed between the mounting plates and the mounting rollers.

[0015] Preferably, one end of the covering film is connected to the outer wall of the mounting roller.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: Fill the filling soil between the supporting high walls and at the top of the culvert top. Subsequently, fill the foam lightweight soil body between the supporting high walls and the supporting low walls. The filled foam lightweight soil body is separated by the partition wall, so that the filling operation can be carried out in batches, avoiding the need to use too much foam lightweight soil body in one construction. The filling soil supports the whole. At the same time, the foam lightweight soil body is a rigid body with good bonding performance. It does not exert lateral pressure on the opposite side walls along the periphery, enhancing the stability of the culvert slope. Replacing part of the soil on the culvert slope with it reduces the acting force affecting the slope stability due to the reduced mass. This structure realizes the construction in batches and prevents serious loss of foam lightweight soil due to long construction time. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The layered structure is located on the side of the culvert side walls 4 away from each other;

[0026] Please refer to Figures 1-4 , a foamed light soil applied to the culvert backfill structure also includes a layered structure. The layered structure includes support high walls 8, and the support high walls 8 are all installed on the sides of the culvert side walls 4 away from each other. At the bottom ends of the front and rear ends of the sides of the culvert side walls 4 away from each other, support low walls 2 are installed. At one end of the support high walls 8 close to the support low walls 2, a plurality of partition walls 5 are installed. Between the support high walls 8 and at the top of the culvert top 7, filling soil 6 is filled. Between the support low walls 2 and the support high walls 8, a foamed light soil body 3 is filled;

[0027] The bottom ends of the support high walls 8 all extend to the top of the soil layer 1, and the bottom ends of the support high walls 8 are all installed on the top of the soil layer 1;

[0028] The partition walls 5 are in an inclined state, and the bottom ends of the partition walls 5 are all installed on the top of the soil layer 1;

[0029] One end of the partition walls 5 close to the support low walls 2 all extends to one end of the support low walls 2, and the partition walls 5 are all installed at one end of the support low walls 2;

[0030] Specifically, as shown in Figure 1 , Figure 2 and Figure 3 , when using this mechanism, the filled foamed light soil body 3 is separated by the partition walls 5, so that the filling operation can be carried out in batches, avoiding the need to use too much foamed light soil body 3 in one construction.

[0031] Embodiment 2: The covering structure 9 includes a covering film 901, a mounting roller 902, a torsion spring 903, a mounting plate 904, and a rotating rod 905. The mounting plates 904 are installed at the upper and lower ends of the mutually remote ends of the culvert side walls 4, and the rotating rod 905 is installed between the mounting plates 904 through a rotating shaft. Mounting rollers 902 are installed on the outer walls of the rotating rod 905, and the covering film 901 is wound around the outer walls of the mounting rollers 902. Torsion springs 903 are sleeved on the outer walls of the rotating rod 905 between the mounting rollers 902 and the mounting plates 904;

[0032] The torsion springs 903 are fixedly installed between the mounting plates 904 and the mounting rollers 902;

[0033] One ends of the covering film 901 are all connected to the outer walls of the mounting rollers 902;

[0034] Specifically, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, when using this mechanism, the torsion spring 903 can be driven to rotate through the mounting roller 902, and the torsion spring 903 is tightened.

[0035] Working principle: Construction workers fill the filling soil 6 between the supporting high walls 8 and fill it at the top of the culvert top 7. Subsequently, the lightweight foamed soil body 3 is filled between the supporting high walls 8 and the supporting low walls 2. The filled lightweight foamed soil body 3 is separated by the partition wall 5, so that the filling operation can be carried out in batches, avoiding the need to use too much lightweight foamed soil body 3 in one construction. The overall structure is supported by the filling soil 6. At the same time, the lightweight foamed soil body 3 is a rigid body with good bonding performance. It does not exert lateral pressure on the opposite bank wall along the periphery, enhancing the stability of the culvert slope. Using it to replace part of the soil on the culvert slope reduces the acting force affecting the slope stability due to the reduced mass;

[0036] After the filling operation is completed, construction workers can install the mounting plates 904 on the culvert side walls 4. Subsequently, the covering film 901 is disengaged from the outer wall of the mounting roller 902. The covering film 901 drives the mounting roller 902 to rotate. The mounting roller 902 can drive the torsion spring 903 to rotate and tighten the torsion spring 903. The covering film 901 is attached to the surface of the lightweight foamed soil body 3, and stones are placed on its surface for fixation. The covering film 901 protects the lightweight foamed soil body 3 to prevent the lightweight foamed soil body 3 from being washed away when rain falls.
