Since the flow of the water body bottom is relatively rapid, when the flow impact force of the water body bottom is greater than the pressure of the sand rib soft mattress, the sand rib soft mattress may be turned over.

[0015] Preferably, the upper geotechnical cloth is arranged above the multiple rows of sand rib sleeves, and the upper geotechnical cloth is sewn on the lower geotechnical cloth and the sand rib sleeve through the reinforcing belt.
[0016] By adopting the technical scheme, the upper geotechnical cloth is arranged above the multiple rows of sand rib sleeves, and the upper geotechnical cloth is connected with the lower geotechnical cloth and the sand rib sleeve through the reinforcing belt, thereby improving the overall strength of the sand rib soft body and reducing the possibility of the sand rib soft body being torn when being discharged.
[0017] Preferably, the lower geotechnical cloth is a reinforced woven composite geotechnical cloth, and the woven cloth is on the top and the non-woven cloth is on the bottom.
[0018] By adopting the technical scheme, the lower geotechnical cloth is a composite geotechnical cloth, thereby improving the tear resistance of the lower geotechnical cloth when the sand rib soft body is discharged.
[0019] Preferably, the bottom end of the sealing pipe is semicircular.

When laying the sand rib soft mattress, the sand mortar is poured into the sand rib sleeve, and when the sand rib soft mattress is laid on the bottom of the water body, the discharge pipe on the sand rib sleeve is inserted into the silt on the bottom of the water body, so that the sand mortar in the sand rib sleeve flows out through the discharge hole on the discharge pipe, and the sand mortar flows into the silt on the bottom of the water body. With the passage of time, the sand mortar in the silt solidifies, thereby further stabilizing the sand rib soft mattress on the bottom of the water body, and reducing the possibility of the sand rib soft mattress being turned over when the water flow on the river bottom is rapid.
[0025] 2. The sealing tube is sleeved on the discharge pipe, and when the sand mortar is poured into the sand rib sleeve, the through port on the sealing tube is misaligned with the discharge hole on the discharge pipe, thereby reducing the possibility of the sand mortar flowing out of the discharge hole on the discharge pipe when the sand mortar is poured into the sand rib sleeve.

[0031] The following will be described in detail with reference to the accompanying drawings Figures 1-3Further details of the application are described below.
[0032] The application discloses a sand rib soft mattress.
[0033] With reference to Figure 1 and Figure 2 The sand rib soft mattress comprises a lower geotextile 1 and a plurality of sand rib sleeves 11 arranged on the lower geotextile 1, the lower geotextile 1 is a reinforced woven composite geotextile, the woven fabric is on the upper side, and the non-woven fabric is on the lower side, the sand rib sleeve 11 is sewn on the surface of the lower geotextile 1 through a reinforcing belt, and an end, away from a grouting port, of the sand rib sleeve 11 is provided with a drainage port 13.
[0034] With reference to Figure 1 and Figure 3 A plurality of discharge pipes 2 are fixed to the outer circumferential surface of the sand rib sleeve 11, the plurality of discharge pipes 2 are arranged at equal intervals along the axial direction of the sand rib sleeve 11, and the discharge pipes 2 are in communication with the sand rib sleeve 11. An end, away from the sand rib sleeve 11, of the discharge pipe 2 penetrates through the lower geotextile 1, and a plurality of discharge holes 21 are formed in the outer circumferential surface of the discharge pipe 2. A sealing pipe 22 is sleeved on the discharge pipe 2, and the bottom end of the sealing pipe 22 is semicircular. An annular groove 23 is formed in the inner circumferential surface of the sealing pipe 22, a limiting ring 24 is fixedly sleeved on the outer circumferential surface of the discharge pipe 2, and the outer circumferential surface of the limiting ring 24 is in abutment with the inner circumferential surface of the annular groove 23. A through port 25 is formed in the outer circumferential surface of the sealing pipe 22, and the through port 25 is in communication with the discharge hole 21. A through hole 27 is formed in the inner bottom surface of the discharge pipe 2, a sealing column 28 is fixed to the inner bottom surface of the sealing pipe 22, and the top end of the sealing column 28 is inserted into the through hole 27. A tension spring 26 is sleeved on the side of the sealing column 28, the top end of the tension spring 26 is fixed to the bottom surface of the discharge pipe 2, and the bottom end of the tension spring 26 is fixedly connected to the inner bottom surface of the sealing pipe 22.
[0035] The implementation principle of the sand rib soft mattress is as follows: when the sand rib soft mattress needs to be laid, the sand rib soft mattress is first laid on a laying ship, the sealing pipe 22 moves upward under the pressure of the sand rib soft mattress, the through port 25 and the discharge hole 21 are staggered, so that the discharge pipe 2 is in a sealed state when grouting into the sand rib sleeve 11, and then the mud in the sand rib sleeve 11 is prevented from leaking out in advance when the sand rib soft mattress is laid on the bottom of the water.
[0036] When the sand rib sleeve 11 is filled with grout, the sand rib soft mattress is laid towards the bottom of the water body through the laying ship, and when the sealing pipe 22 is separated from the laying ship, the sealing pipe 22 moves downward under the elastic force of the tension spring 26, so that the through port 25 is aligned with the discharge hole 21.
[0037] When the sand rib soft mattress sinks to the bottom of the water body, the sealing tube 22 and the discharge pipe 2 are inserted into the silt at the bottom of the water body, so that the mortar in the sand rib sleeve 11 flows out through the discharge hole 21 and the through hole 25, and the mortar in the outflow part seeps into the silt. With the passage of time, the mortar flowing into the silt solidifies, thereby further improving the stability of the sand rib soft mattress laid on the bottom of the water body, and further reducing the possibility of the sand rib soft mattress being turned over when the water flow at the bottom of the water body is relatively rapid.
[0038] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
