Description
Technical field:
the utility model relates to a rapid blocking device for dam loopholes, which belongs to the technical field of dam and dam rescue in hydraulic engineering, and has IPC international patent classification numbers of E02B 1/00 and E02B 3/16.
The background technology is as follows:
the loopholes are dangerous situations with extremely high safety threat to river dikes and reservoir dams, and the formed back holes have high flow rate and strong flushing, and if the dikes are damaged due to improper robbing.
According to the principle of 'front blocking and back guiding and face-back combination', the rescue of the water inlet of the leak is usually carried out according to three stages of detection, blocking and gas closing. The "front plug" location is typically a leaky water inlet, i.e., a single stage plug is made at the water inlet only. Correspondingly, a single-stage gas-closing method is adopted outside the water inlet plugging material, and the gas-closing part is limited outside the water inlet.
The key of successful rescue of the loopholes is that plugging and gas closure are completed rapidly after the inlet position is determined. The patent 'a dam leak plugging device' (patent number: CN 107059792B, bulletin day: 2018, 9 and 14) discloses a dam leak plugging device adopting super absorbent resin as an expansion material, which mainly comprises duckweed-shaped floaters, conical connecting ropes, super absorbent resin balls, serial ropes, balancing weights and traction ropes, and can be used for graded plugging and air-closing at a leak water inlet section. However, through practical application in recent years, the device is found to still have the following defects:
(1) The high water absorption resin material is arranged in a packaging bag consisting of a sealing bag, a water soluble bag and a water permeable bag, when the device is used, the sealing bag is opened first, the device enters a leak and the water soluble bag is dissolved 5-50 min after water is filled in the water soluble bag. Because the dangerous situations of the loopholes develop rapidly, the dissolution and the expansion time of the super absorbent resin material are difficult to be accurately controlled through the water-soluble bag, and the requirement of 'early-robbing and small-robbing' cannot be met.
(2) The duckweed-shaped floater is unstable in ring-mounted structure; after the covered composite geotechnical material is soaked in water, the generated buoyancy is difficult to maintain the whole device to be suspended in the water body, and plugging failure is easy to cause.
(3) The conical connecting rope fixed on the inner ring is difficult to completely enter the loophole, so that secondary damage is easily caused to the water inlet of the loophole, and dangerous situations are aggravated.
(4) After the super absorbent resin ball is expanded, the longitudinal length is large and the transverse dimension is small under the influence of the hole wall. The swelling volume of the super absorbent resin beads, particularly the longitudinal swelling, does not sufficiently play a role in blocking (in the present utility model, the longitudinal direction means the length direction of the leak, and the lateral direction means the direction perpendicular to the length of the leak).
(5) The weight of balancing weight is relatively fixed, is difficult to carry out adaptability adjustment according to the whole quality and the volume of the device.
