Embodiment 1

[0014] Such as figure 1 As shown, a simple rolling dam includes a trapezoidal sand weir 1, the slope of the receding slope of the sand weir 1 is 1:0.6, and the side of the receding slope of the sand weir 1 is provided with a combined protection Retaining, interlayer cloth 2 is provided between the combined retaining and the sand weir 1, and a groove 5 not less than 50 cm deep is provided at the slope foot of the receding side slope of the sand weir 1, and the combined retaining and interlayer cloth 2 Extending in the groove 5, the groove 5 is backfilled, and one side of the groove 5 is provided with an apron 6, and one end of the apron 6 goes deep into the groove 5 to wrap the outer side of the composite shield and connect with the interlayer cloth 2. Protective cloth 6 adopts fire-resistant three-dimensional grass net or clothes cloth and connects.

[0015] The combined guard includes several wooden gate legs 3 arranged in parallel, the lower ends of the wooden gate legs 3 g...

Embodiment 2

[0024] Such as figure 2 As shown, a simple rolling dam includes a trapezoidal sand weir 1, the slope of the receding slope of the sand weir 1 is 1:0.6, and a stone wall is provided on one side of the receding slope of the sand weir 1 There is an interlayer fabric 2 between the ridge 7, the stone ridge 7 and the sand weir 1, and a trench 5 not less than 50 cm deep is provided at the foot of the receding slope of the sand weir 1, and the stone ridge 7 and the interlayer fabric 2 extends in the groove 5, the groove 5 is backfilled, and the side of the groove 5 is provided with an apron 6, and one end of the apron 6 goes deep into the groove 5 to wrap the outer side of the composite shield and connect with the interlayer cloth 2. Protective cloth 6 adopts fire-resistant three-dimensional grass net or clothes cloth and connects.

Abstract

The invention belongs to the technical field of farmland water conservancy and particularly relates to a simple-type rolling dam. The problems that a traditional rolling dam is high in cost and not durable are solved. The simple-type rolling dam comprises a trapezoidal sandy soil transverse weir; the gradient of the surface of a water subsiding square slope of the sandy soil transverse weir is 1:0.6; a combination protective guard is arranged on one side of the surface of the water subsiding square slope of the sandy soil transverse weir, and a sandwich cloth is arranged between the combination protective guard and the sandy soil transverse weir; a groove with the depth being no less than 50 cm is formed in the slope toe of the water subsiding square slope of the sandy soil transverse weir; the combination protective guard and the sandwich cloth extend in the groove; the groove is backfilled; an apron cloth is arranged on one side of the groove; and one end of the apron cloth extends into the groove to wrap the outer side of the combination protective guard and to be connected with the sandwich cloth. The simple-type rolling dam is simple and easy to conduct, the construction costis extremely low, and the simple-type rolling dam is dismantled after being used without affecting riverway safe flood passing.

Description

technical field [0001] The invention belongs to the technical field of farmland water conservancy, in particular to a simple rolling dam. Background technique [0002] After the founding of New China, large-scale and continuous basic construction of farmland water conservancy, water and soil conservation engineering and river channel flood control have been carried out in the vast hilly areas of our country, and unprecedented grand construction achievements have been achieved. However, since the basic farmland construction is done by pulling soil padding, the thickness of the padding soil can reach 50cm after it is settled, and the average cost per mu will exceed 10,000 yuan; with the land, the problem of flood control must be solved, and it can really prevent floods for a long time. The cost of extending a meter-long flood control dam built with stone slurry is more than 1,400 yuan, and the average cost per mu is no less than that of padding. Due to the influence of river ...
