Description

Technical Field

[0001] The utility model relates to the technical field of filter layer construction, in particular to a tool used for filling a filter layer. Background Art

[0002] During the construction of the water collection corridor of the water diversion project, it is necessary to set up a filter layer between the side wall of the water collection corridor of the water diversion project and the soil in the foundation. After the filter layer is set up, the infiltrated water will not take away the soil in the foundation when it flows out, thereby preventing the occurrence of soil flow, ensuring the clear water quality flowing into the water collection corridor, and preventing the water supply pipeline from being blocked.

[0003] The filter layer is made of 2-4 layers of filter materials such as sand, gravel or pebbles with different particle sizes. The particles gradually increase in size along the direction of water flow. During the construction process, since the particles in any layer of the filter layer are not allowed to pass through the pores of the adjacent coarser layer, controlling the boundary between the layers becomes a difficult problem in the construction of the filter layer, which restricts the construction efficiency.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings of the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0026] This embodiment provides a tool for filling the filter layer, such as Figure 1 As shown, the tooling for filling the filter layer includes a peripheral enclosure plate and an intracavity partition plate. The peripheral enclosure plate includes two lengthwise steel plates 1 arranged along the length direction of the filter layer and two plugging steel plates 2 arranged along the width direction of the filter layer; the lengthwise steel plates 1 are 5m long, 1.53m wide and 3mm thick; the plugging steel plates 2 are 1.53m long, 1.5m wide and 3mm thick; the two lengthwise steel plates 1 and the two plugging steel plates 2 are welded and fixed to enclose a rectangular cavity structure 3 with openings at the top and bottom.

[0027] like Figure 1 As shown, there are two intracavity baffles 4, and the size parameters of the two intracavity baffles 4 are connected to the length direction steel plate 1. The two side ends of the intracavity baffles 4 are respectively welded and fixed to the plug steel plate 2, so as to be fixedly arranged in the rectangular cavity structure 3 and arranged parallel to the length direction steel plate 1. Figure 1 and Figure 2 As shown, the rectangular cavity structure 3 is divided into three filling cavities 5 of equal size along the length direction of the filter layer by two intra-cavity partitions 4, and the three filling cavities 5 are filled with filter materials of different particle sizes through the top openings.

[0028] When the tooling used for filling the filter layer is used, Figure 3As shown, the tooling for filling the filter layer is hoisted as a whole to the construction position of the filter layer by a crane, that is, between the side wall 11 of the water collection corridor and the foundation soil; then each type of stone block with a particle size is backhoeed into the warehouse and filled into the corresponding filling cavity 5 through the top openings of the three filling cavities 5; after the filling is completed, the tooling for filling the filter layer is transported to the next section by a crane, and the filling is carried out in the same way, thereby improving the filling construction speed.

[0029] Further, as a preferred technical solution of this embodiment, Figure 4 As shown, for the convenience of lifting, in this embodiment, a lifting ring 6 for lifting is symmetrically provided on the top of the steel plate 1 in the length direction. In addition, considering the structural strength of the rectangular cavity structure 3, as shown in FIG. Figure 1 As shown, in this embodiment, four stud bolt rods 7 are arranged between the longitudinal steel plate 1 and the intracavity partition 4, and four stud bolt rods 7 are arranged between the intracavity partition 4 and the intracavity partition 4. The two ends of the stud bolt rods 7 pass through the longitudinal steel plate 1 or the intracavity partition 4 and are fixed by nuts 8. Figure 2 As shown, three reinforcing angle steels 9 arranged along the length direction of the filter layer are welded and fixed on the side plate surface of the length direction steel plate 1 and the cavity partition plate 4, as shown in FIG. Figure 4 As shown, the longitudinal steel plate 1 and the other side plate surface of the cavity partition 4 are welded and fixed with round steel 10 arranged crosswise in the horizontal and vertical directions, so as to increase the single plate strength of the rectangular cavity structure 3 and the overall structural strength. Example 2

[0030] On the basis of Example 1, in order to save the material for making the tooling for filling the filter layer, as Figure 5 and Figure 6 As shown, a longer plugging steel plate 2 can also be used, so that one side of the two plugging steel plates 2 extends to the outside of the rectangular cavity structure 3, such as a steel plate with a length of 2m, a width of 1.5m and a thickness of 3mm.

[0031] After the length direction steel plate 1, the plugging steel plate 2 and the intra-cavity partition plate 4 are installed and fixed according to the connection method in Example 1, one side of the two plugging steel plates 2 extends 0.5m outside the rectangular cavity structure 3, and the two plugging steel plates 2 cooperate with the side wall 11 of the water collection corridor to enclose an additional filling cavity 5, thereby forming four filling cavities 5.

[0032] When the tooling used for filling the filter layer is used, Figure 6As shown, the tooling for filling the filter layer is hoisted as a whole to the construction position of the filter layer by a crane, so that the two plugging steel plates 2 cooperate with the side walls 11 of the water collection corridor to enclose an additional filling cavity 5; then each type of stone block with a particle size is backhoeed into the warehouse and filled into the corresponding filling cavity 5 through the top openings of the four filling cavities 5; after the filling is completed, the tooling for filling the filter layer is transported to the next section by a crane, and the filling is carried out in the same way, thereby improving the filling construction speed. Example 3

[0033] On the basis of Example 1, the following problems were found through actual use of the tooling for filling the filter layer: in the process of filling stones of each particle size, since there is no door panel at the top opening of each filling cavity 5, when filling stones into one filling cavity 5, a small amount of stones may accidentally fall into other adjacent filling cavities 5.

[0034] To solve this problem, Figure 7 As shown, in this embodiment, a hinge plate 13 is rotatably installed on the top of the steel plate 1 and the cavity partition 4 in the longitudinal direction through a hinge 12; Figure 8 As shown, the hinge plate 13 is arranged along the length direction of the filter layer, and its length is equal to the length direction of the steel plate 1. One side of the hinge plate 13 is connected to the hinge 12, and the other side is provided with a steel plate fastener 14; Figure 7 As shown, the top opening of the filling cavity 5 can be closed by overlapping and buckling two adjacent pieces.

[0035] When the tooling for filling the filter layer is used, the top opening of the middle filling cavity 5 is first closed by the hinge plate 13, and then the filling cavities 5 on the left and right sides can be filled with stones; after the filling is completed, the top openings of the filling cavities 5 on the left and right sides are closed by the hinge plate 13, and then the middle filling cavity 5 can be filled with stones; this prevents the stones from falling into other adjacent filling cavities 5 when filling one filling cavity 5.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
