Interception net dam

Abstract

The invention relates to an interception net dam arranged between a river bed of a river and both bands. The dam comprises a skeleton unit and a net frame unit, wherein the skeleton unit comprises two under frames, two first upright frames fixed on the under frames respectively and extended toward the top end, a plurality of bottom connecting rods fixed between the under frames and a first top connecting rod fixed between the first upright frames; and the net frame unit comprises a first interception net which comprises a first bottom net fixed between the under frames, an upright net fixed between the first upright frames and two first wing nets arranged between the first upright frames and the banks respectively. Due to the adoption of the structure, the first interception net can intercept larger stones and sundries, and prevent the interception net dam from collapsing through the downward gravity generated by the piled stones and sundries, so that the dam has the characteristics of having short construction period and effectively saving labor and material resources.

Description

technical field [0001] The invention relates to an intercepting net dam, in particular to an intercepting net dam for intercepting relatively large stones and sundries in rivers and rivers. Background technique [0002] Please refer to Fig. 1, which is a perspective view of a general existing sand retaining dam. In order to prevent stones and sundries in the river from silting up with the water flow, a sand dam 20 is usually implemented at a predetermined place in the river 10. The sand dam 20 has a base 21 embedded in the river bed 11, and a base 21 from the base 21 A plurality of uprights 22 extending toward the top and spaced apart from each other, each two uprights 22 cooperate to form a gap 23 for water, sand and small stones to pass through. As for larger stones 12 or sundries, they are blocked by the column 22 because they cannot pass through the gap 23 . [0003] Although this sand retaining dam 20 has the use function that can intercept larger stones 12 and sundri...

AI Technical Summary

Problems solved by technology

[0004] 1. Because the base 21 and column 22 of the sand control dam 20 are poured into the riverbed 11 with concrete, the construction period is longer, the river ecology is easier to be destroyed, and more manpower is required to complete it.

[0005] 2. Because the sand control dam 20 needs to have a certain thickness in order to resist the impact force of the water surface, there is a relatively heavy overall weight and a lack of more material resources to complete

[0006] It can be seen that the above-mentioned existing sand retaining dam obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
