When constructing the flexible mattress 100, the tying ropes 30 are arranged on the mattress body 10 through the tying belts 20. The two free ends of the tying ropes 30 are laid out flatly outward. After the ballast blocks 40 are pressed on the mattress body 10, the two free ends of the tying ropes 30 are buckled through the locking fasteners 50 so that the two free ends are respectively fastened on the locking fasteners 50. At this time, the tying ropes 30 tightly hold the outside of the ballast blocks 40, so that the ballast blocks 40 are weighted at the fixed position of the mattress body 10. During specific operation, the locking fastener 50 is arranged to include a buckle body 51 and conical barrel buckle feet 52. The two conical barrel buckle feet 52 are arranged on the mouth body at intervals.

The small-diameter section of the conical barrel buckle feet 52 is an elastic buckle section. The free end of the tying rope 30 is provided with an outward convex buckle position 31. When tying is required, the free end of the tying rope 30 extends into the large-diameter section of the conical barrel buckle feet and passes through the elastic buckle section. After the outward convex buckle position 31 passes through the elastic buckle section, the elastic buckle section undergoes plastic deformation and tightens to abut against the outward buckle position. The free end of the tying rope 30 is locked on the mouth body.

[0035] It can be understood that the tying belts 20 and the tying ropes 30 can be arranged on the mattress body 10 in advance. The mattress body 10 is arranged in a rolled-up state before construction. After the mattress body 10 is laid flat during construction, the tying belts 20 and the tying ropes 30 are automatically arranged at the same time, which is beneficial to improving the construction efficiency and saving construction manpower. Optionally, the tying belts 20 are fixedly connected to the mattress body 10, and the middle part of the tying ropes 30 is fixed through the tying belts 20.

[0037] In a specific solution of the present utility model, the tying belt 20 is sewn on the row body 10, and the tying rope 30 is arranged through the gap between the tying belt 20 and the row body 10; the locking buckle 50 is a plastic buckle; the weight pressing block 40 is a concrete block; the elastic buckle section has the elastic potential energy of automatic closing, and thus tightens after the tying rope 30 passes through and makes the head abut against the convex buckle position 31 on the tying rope 30.

[0038] In the present utility model, the buckle body 51 can be integrally formed. At this time, the conical barrel buckle feet 52 are formed on the mouth body by injection molding; or the buckle body 51 is a splicable split structure. At this time, the conical barrel buckle feet 52 can be separately formed.

[0039] It can be understood that the radial dimension of the convex buckle position 31 is larger than the opening dimension of the elastic buckle section.

[0040] Please refer to Figure 5 and Figure 6 , further, in order to ensure the elastic contraction and deformation ability of the elastic buckle section, the elastic buckle section is provided with deformation margin slots 501 arranged through the side wall surface, and at least two deformation margin slots 501 are arranged at intervals along the circumferential direction of the conical barrel buckle feet 52.

At this time, the elastic buckle sections of the two conical barrel buckle feet 52 are both arranged facing upward, and the tying rope 30 abuts against the upper end of the elastic buckle section after passing through from the bottom; when the locking buckle 50 (conical barrel buckle feet 52) is arranged horizontally (the direction parallel to the surface of the row body 10), the two conical barrel buckle feet 52 are arranged in central symmetry on the buckle body 51. At this time, the elastic buckle sections of the two conical barrel buckle feet 52 are arranged in the reverse direction, the elastic buckle sections are arranged facing the corresponding side tying rope 30, and the tying rope 30 abuts against the end surface of the elastic buckle section after passing through from the large diameter section.

[0044] Further, for the convenience of fastening, a plurality of outwardly protruding fastening positions 31 are arranged at intervals along the length direction of the tether 30.

It can be understood that by providing the first notch and the second notch, and arranging the conical barrel fastening leg 52 rotatably around the central axis, it is possible to avoid passing through the large-diameter section of the conical barrel fastening leg 52 and pulling out from the small-diameter section. During construction, only the first notch and the second notch need to be aligned, and then the free end of the tether 30 is passed through the first notch and the second notch, and then the conical barrel fastening leg 52 is rotated and the tether 30 is stretched to lock.

[0046] Further, a plurality of outwardly protruding fastening positions 31 are arranged at intervals along the length direction of the tether 30. It can be understood that outwardly protruding structures may be arranged on the surface of the tether 30 to form the outwardly protruding fastening positions 31, or the tether 30 may be pre-knotted to form the outwardly protruding fastening positions 31.

[0047] It can be understood that in order to improve the construction efficiency, a locking fastener 50 may be pre-mounted on one free end of the tether 30. Specifically, one free end of the tether 30 passes through the large-diameter end of the conical barrel fastening leg 52 and extends out from the small-diameter end, and at least one outwardly protruding fastening position 31 extends out of the small-diameter section.

[0048] Further, during specific assembly, an installation boss 522 is arranged on the large-diameter section of the conical barrel fastening leg 52, and an installation groove 512 is recessed on the fastening body 51.

[0049] More preferably, a hemispherical protrusion is arranged on the circumferential outer wall surface of the installation boss 522, and a hemispherical bayonet is recessed on the groove wall surface of the installation groove 512 of the fastening body 51. After the tether 30 passes through, the conical barrel fastening leg 52 is rotated to misalign the first notch groove 511 and the second notch groove 521, and at this time, the hemispherical protrusion and the hemispherical bayonet are cooperated for circumferential limiting.

[0050] Further, a constraint groove group is provided on the weight 40. A set of constraint groove groups includes two constraint grooves 401 symmetrically arranged on the side wall surface of the weight 40. The tether 30 is arranged corresponding to the constraint groove group, and the free end of the tether 30 passes through the corresponding constraint groove 401.
