1.
Traditional emergency protection technology can be roughly divided into well filtering method
, filtering and covering method and water pressure infiltration method.
The well back-filtration method is generally used for small and large piping groups with a small number and small area on the backwater surface, as well as piping groups that are large in number but are not connected into a large area and can be treated in pieces. According to the different seepage conduction materials used, it can be divided into sand and gravel back filtration around the well, back filtration with tip material around the well, geotextile back filtration around the well, filterless back pressure method, and water basin method.
The anti-filtration and blanketing method is mainly used for piping groups with many connected piping groups. Currently, the commonly used filter blankets include geotextile filter blankets, sand and gravel filter blankets, and tip material filter blankets.
The water-permeable pressure infiltration method is to first remove soft mud and debris within the scope of piping. For more serious piping mouths, use sand or stones to fill them. After the water potential is eliminated, use highly permeable materials. The sand construction platform can balance the seepage pressure, increase the length of the seepage path, reduce the seepage slope, and can guide the seepage water to prevent the disappearance of soil particles and control the danger.
A new technology and equipment for protecting piping surge damage was developed by Hebei Wuxing Electric Power Equipment Co., Ltd. and used in flood prevention and rescue operations across the country, and has achieved good results. A new technology and new equipment for protecting piping damage breaks through the traditional concepts in the construction of enclosure wells and the installation of filter layers. It adopts assembled enclosure wells and geotechnical filter mats, which is not only suitable for protecting individual piping surges, but also for protecting piping surges. Protective tube surge group.
2. The structure of the type flood control prefabricated well enclosure
The prefabricated enclosure is mainly composed of folding recoil unit enclosures, fixings, drainage system and water stop system. The size of the enclosure can be assembled according to the actual situation of the piping hazard and the rescue requirements. It is generally ~ times the diameter of the piping hole.
The water depth in the enclosure is adjusted by the drainage system. The unit hoarding is the main component of the flood control assembled well hoarding, which is composed of water retaining hoardings, reinforced angle irons and connectors. Hebei Wuxing Electric Power Equipment Co., Ltd.'s patented product, the prefabricated well enclosure adopts a folding recoil structure, which is convenient for rapid transportation and storage, and is easy to assemble quickly during use. The water-retaining hoarding is made of waterproof hard boards such as plastic hard boards or fiberglass reinforced plastics as the base material, and angle steel is used as the supporting frame. The plastic hard plate material of the well enclosure should be new polyvinyl chloride or fiberglass plate.

The salient features of Hebei Five Star Electric Power Equipment Co., Ltd.’s series of flood control well enclosure panels used to protect piping surges
, and Compared with traditional reverse filter materials, flood control geofilter mats are light in weight, simple and fast to connect, and effective. There is no risk of siltation failure and other risks.
. Compared with the traditional way of constructing well enclosures, prefabricated enclosure wells are simple to install, have good effects, and save labor and effort. ?
, can greatly improve the rescue speed, save rescue time, and reduce the intensity of rescue.
