Description

Technical Field

[0001] The present invention relates to the technical field of waterway regulation engineering, and particularly to a D-type interlocking flexible mattress and a dry-laying construction method thereof. Background Art

[0002] During the waterway regulation process of water transportation projects, it is necessary to protect the shoals in the waterway to prevent the shoals from being scoured. In the prior art, D-type interlocking sheets are usually used, that is, protection is carried out by covering with a sunken D-type interlocking flexible mattress. The sunken D-type interlocking flexible mattress is to lay a geotextile flexible mattress on a waterway sinking ship, and then tie the D-type interlocking sheets and move the sinking ship to sink the D-type interlocking sheets and the geotextile flexible mattress underwater to cover the shoals that need to be protected. In the prior art, due to the need for large equipment to cooperate in construction, construction is generally carried out only when the water level rises and the water area is large, so it is necessary to wait for seasonal water level changes, which will probably cause delays in the construction period. Especially for the shoals exposed above the water surface, the construction period is extremely delayed. Summary of the Invention

[0003] Aiming at the deficiencies in the prior art, the present invention provides a D-type interlocking flexible mattress, which solves the problem that the protection of the shoals exposed above the water surface in the prior art may cause delays in the construction period.

[0004] According to an embodiment of the present invention, a D-type interlocking flexible mattress includes a geotextile covering layer, and a plurality of interlocking sheets arranged above the geotextile covering layer. The interlocking sheets are connected in series in an S-shaped structure by a first connecting cable and arranged in a regular M-row and N-column layout. All the interlocking sheets in each row or column are also connected in series by a second connecting cable, and the first connecting cable and the second connecting cable are arranged in a cross shape at each interlocking sheet. Both ends of the second connecting cable are fixedly connected with a first connecting buckle, and a plurality of second connecting buckles connected to each first connecting buckle are also fixedly connected to the geotextile covering layer; it also includes a sand layer covering all the interlocking sheets and the geotextile covering layer. The geotextile covering layer is directly covered and set on the shoal, and then the interlocking sheets and the sand layer are set in sequence, without waiting for the water level to rise, which solves the problem that the protection of the shoals exposed above the water surface in the prior art may cause delays in the construction period.

[0005] Further, a plurality of positioning areas are arranged on the geotextile covering layer, and each positioning area is provided with interlocking sheets arranged in M rows and N columns.

[0006] Further, a plurality of mattress sinking beams are arranged on the edge of the geotextile covering layer, and the mattress sinking beams are connected to the adjacent interlocking sheets through corresponding first connecting buckles.

[0007] Further, a plurality of mattress sinking beams are arranged on the edge of the geotextile covering layer, and the mattress sinking beams are pressed on the adjacent first connecting buckles.

[0008] Furthermore, a third connecting cable is wound around between the mattress beam and the geotextile covering layer. Positioning rings are provided at both ends of the third connecting cable, and positioning nails passing through the geotextile covering layer are arranged through the positioning rings.

[0009] Furthermore, the surface of the geotextile covering layer within the positioning area is recessed with positioning grooves for receiving parts of each interlocking sheet in M rows and N columns respectively.

[0010] Furthermore, third connecting buckles are fixedly connected to both ends of the first connecting cable respectively, and a number of fourth connecting buckles connected to each third connecting buckle are also fixedly connected to the geotextile covering layer.

[0011] Furthermore, the distance between two adjacent interlocking sheets is less than the length of the first connecting cable or the second connecting cable between them.

[0012] According to the embodiment, a construction method for dry-laying a D-type interlocking flexible mattress is also provided. A geotextile is used to cover the surface of the shoal to form a geotextile covering layer, then a plurality of interlocking sheets in M rows and N columns are hoisted onto the geotextile covering layer, and a mattress beam is hoisted at the edge of the geotextile covering layer. The geotextile covering layer, the interlocking sheets and the mattress beam are connected, and finally sand is covered to form a sand layer.

[0013] Furthermore, positioning grooves corresponding to each interlocking sheet in M rows and N columns are recessed on the surface of the shoal.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] It can facilitate the construction on the shoal exposed above the water surface, that is, directly cover and set the geotextile covering layer on the shoal, and then sequentially set the interlocking sheets and the sand layer. There is no need to wait for the water level to rise, solving the problem that the protection of the shoal exposed above the water surface in the prior art may cause a delay in the construction period; covering the sand layer on the geotextile covering layer and the interlocking sheets can prevent the geotextile covering layer from decaying due to direct sunlight.

[0022] The technical solutions in the present invention will be further described below in conjunction with the attached drawings and embodiments.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the attached drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0024] In an exemplary embodiment, such as Figure 1 , 2As shown in the figure, this embodiment provides a D-type interlocking flexible mattress, which includes a geotextile covering layer 1 and a number of interlocking plates 2 arranged above the geotextile covering layer 1. The interlocking plates 2 are connected in series by a first connecting cable 3 in an S-shaped structure and arranged in a regular M-row and N-column pattern. All the interlocking plates 2 in each row or column are also connected in series by a second connecting cable 4, and the first connecting cable 3 and the second connecting cable are arranged in a cross pattern at each interlocking plate 2. Both ends of the second connecting cable 4 are fixedly connected with a first connecting buckle 5, and a number of second connecting buckles connected to each first connecting buckle 5 are also fixedly connected to the geotextile covering layer 1; it also includes a sand layer 6 covering all the interlocking plates 2 and the geotextile covering layer 1. In this solution, the provided geotextile covering layer 1 is a civil engineering coil made of synthetic fibers by weaving or non-woven processes such as cementing and hot-pressing needle punching, and has good tear resistance. During construction, first, the ground of the shoal 12 is leveled. When leveling, positioning grooves 7 that are recessed downward can be set. Each positioning groove 7 or multiple positioning grooves 7 correspond to a positioning area. The positioning grooves 7 within the positioning area are square structures. The provided geotextile covering layer 1 can be composed of multiple pieces of geotextiles spliced together. Then, M rows and N columns of interlocking plates 2 are hoisted into each positioning groove 7. The M rows and N columns of interlocking plates 2 provided in each positioning groove 7 are connected in series by an S-shaped first connecting cable 3 and multiple linear second connecting cables 4 into a square structure, and are connected into a whole and pressed on the geotextile covering layer 1. Finally, sand is covered on the geotextile covering layer 1 to form the final sand layer 6, covering all the interlocking plates 2 and the geotextile covering layer 1 below the surface of the sand layer 6 to avoid direct sunlight; at the same time, such construction does not require waiting for the water level to rise, thus solving the problem in the prior art that the protection of the shoal 12 exposed above the water surface may cause a delay in the construction period.

[0025] In a further solution, as Figure 1 , 2 shown, the first connecting buckles 5 between adjacent M rows and N columns of interlocking plates 2 can be commonly connected to a second connecting buckle. Through the connection between the first connecting buckle 5 and the second connecting buckle, the corresponding M rows and N columns of interlocking plates 2 can be connected to the geotextile covering layer 1 to form a partial integral structure, further enhancing the structural stability; furthermore, both ends of the first connecting cable 3 are fixedly connected with a third connecting buckle 8, and a number of fourth connecting buckles connected to each third connecting buckle 8 are also fixedly connected to the geotextile covering layer 1, further enhancing the overall structural stability.

[0026] As Figure 2 shown, during hoisting construction, it is necessary to adjust the positions of the interlocking plates 2 so that the distance between adjacent interlocking plates 2 is less than the length of the first connecting cable 3 or the second connecting cable 4 between them, that is, so that adjacent pairs of interlocking plates 2 are not in a tensioned state, ensuring relative independence.

[0027] like Figure 1 , 3 As shown in FIG. 4 , in order to further improve the stability of the overall structure, the geotextile cover layer 1 is also provided with a plurality of sinking beams 9 located at its edge. In the first exemplary structure (such as Figure 3 ), the sinking beam 9 and the adjacent interlocking piece 2 are connected by a corresponding first connecting buckle 5. In the second exemplary structure (such as Figure 4 ), the sinking beam 9 is pressed onto the first connecting buckle 5 adjacent to it, so that the sinking beam 9, the geotextile covering layer 1 and the interlocking piece 2 are connected as a whole. The sinking beam 9 is pressed onto the edge of the geotextile covering layer 1, which can increase the stability at the edge of the beach 12, thereby improving the stability of the overall structure; further, a third connecting rope 10 is also arranged around the sinking beam 9 and the geotextile covering layer 1, and positioning rings 11 are provided at both ends of the third connecting rope 10, and the positioning rings 11 pass through positioning nails that penetrate the geotextile covering layer 1, and the positioning nails can be deeply inserted into the beach 12 below to play a reinforcing role, and at the same time, the connection between the sinking beam 9 and the geotextile covering layer 1 is further made more stable; in a more detailed scheme, the interlocking pieces 2 of two adjacent M rows and N columns can be connected to one sinking beam 9 together, so that the integrity between the two interlocking pieces 2 of M rows and N columns can be further improved through the sinking beam 9.

[0028] The D-type interlocking plate 2 soft row provided in the present solution does not need to wait for the water level to rise, and can be directly dry-laid on the beach 12, which can greatly save the construction period and solve the problem that the protection of the beach 12 exposed above the water surface in the prior art may cause delays in the construction period; the interlocking plate 2 and sinking beam 9 used in the present solution are prefabricated concrete parts, and the first connecting cable 3 and the second connecting cable 4 are pre-embedded and connected in the interlocking plate 2, so that multiple (i.e., M rows and N columns) interlocking plates 2 form a whole, which is convenient for lifting, can further facilitate the construction, and save the construction period to a greater extent; in more detail, the first connecting cable 3, the second connecting cable 4, the third connecting cable, the first connecting buckle 5, the second connecting buckle, the third connecting buckle 8, the fourth connecting buckle and the positioning ring 11 can all be made of polypropylene material, which has a high cost performance. Furthermore, covering the sand layer 6 on the geotextile cover 1 and the interlocking plate 2 can prevent the geotextile cover 1 from decaying due to direct sunlight.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
