The invention discloses a municipal water supply and drainage structure having an anti-blocking function. The municipal water supply and drainage structure comprises a ditch body, wherein a ditch cover is arranged at the upper side of the ditch body; a cleaning mechanism, which lifts along with a water level in the ditch body, is arranged at the lower side of the ditch cover; the cleaning mechanism comprises a conveying belt; barbs are arranged on the conveying belt; the barbs obliquely point to the moving direction of the conveying belt; a collection groove is arranged in the end, close to atensioning roller, of the ditch body; a partition board is arranged between the collection groove and the ditch body; a collection port, which communicates with the collection groove and the ditch body, is arranged in the partition board; one end of the tensioning roller extends into the collection groove via the collection port; baffle plates are arranged at two ends of a rotating shaft; baffle notches, which are matched with the barbs, are arranged in the baffle plates; and moving cavities, which are matched with the baffle plates, are arranged in the partition board at the lower end of thecollection port. According to the municipal water supply and drainage structure provided by the invention, an effect of cleaning plastic bags floating a drainage ditch can be cleaned more effectivelycan be achieved.

The reinforced concrete pipe making machine consists of mainly frame, suspension roller shaft fixed to the frame, gate head supported in the front of the suspension roller shaft, main shaft connected to the back end of the suspension roller shaft, driving mechanism connected to the main shaft, material feeding mechanism and pipe mold. The bearing in the front end of the suspension roller shaft is supported in the gate head bearing seat, the main shaft bearing is in the frame bearing seat, the jack fixed in the back end of the main shaft on the frame has head perpendicular to the main shaft axis, and the main shaft and the suspension roller shaft have angle to the horizontal plane of 0-3 deg. The pipe mold has flanged edges on two ends connected separately with spigot mold and socket mold separately. The present invention is suitable for producing high strength reinforced concrete pipe with spigot mold and socket.

The invention discloses a ditch anti-blocking recharge filtering device, and belongs to the technical field of aquifer recharge, namely groundwater artificial recharge. The ditch anti-blocking recharge filtering device comprises a ditch, a labyrinth weir structure, a sloping plate filter structure and a dredging well, and the labyrinth weir structure is laid on a ditch slope, and comprises a plurality of labyrinth weir monomers; each labyrinth weir monomer comprises filter plates I and filter plates II, and the filter plates I and the filter plates II are each provided with a plurality of water inlets; the filter plates I, the filter plates II and the ditch slope enclose and form a water storage cavity, and the water storage cavity is vertically formed along the ditch slope; and one end ofthe sloping plate filter structure communicates with the labyrinth weir structure, and the end, far away from the labyrinth weir structure, of the sloping plate filter structure communicates with thedredging well through a collector pipe which is provided with a plurality of drain holes. According to the ditch anti-blocking recharge filtering device, the area of a river channel is not occupied,and water flow is not affected; and the filtering device is prevented from being blocked by sediments, and the filtering efficiency is improved.

An embodiment of the present invention provides a composite electrode for water treatment based on a metal-based fiber material, comprising: a metal fiber matrix, a micro-nano configuration metal surface layer, a metal oxide catalyst layer and a surface modification layer; the micro-nano configuration metal surface layer is A metal surface layer with micro-nano morphology of micro-columns, micro-wires, micro-rods, nano-rods or nano-wire arrays grown on a metal fiber substrate; the metal oxide catalytic layer is an in-situ growth on the micro-nano configuration metal surface with A metal oxide array with nanowire, nanorod or nanocone morphology; the surface modification layer is a superhydrophobic coating or a conductive coating supported on the metal oxide catalytic layer. The invention has high surface area ratio, high surface area, high effective area under unit mass electrode (specific electrode mass active area), and is suitable for different water treatment scenarios due to the special micro-nano interface characteristics and the open structure of the fiber electrode, and has strong oxidizing ability at the same time. , excellent mass transfer performance, long service life, easy processing, low energy consumption.

The invention relates to a welding method for tension rib plates for welding seams of high-temperature environment pipelines and belongs to the technical field of high-temperature pipeline maintenancemethods. The welding method is used for welding the tension rib plates to the high-temperature environment pipeline welding seams. According to the technical scheme, sunroof holes are cut in the welding seam cracking portions of the pipelines, the tension rib plates are welded to the inner walls of the pipeline welding seam cracking portions where the sunroof holes are located of the pipeline, the tension rib plates are evenly distributed on the periphery of the inner wall of each pipeline, and due to the fact that no burning problem is generated when the tension rib plates are in the water-cooling pipelines, the welding seam strength is ensured, and the function of long-term reinforcement of the pipeline welding seam cracking portions is played. The welding method is the first of pipeline maintenance in the high temperature environment, a traditional tension rib plate welding method is broken through, the tension rib plates are creatively welded to the inner walls of the pipelines, the burning problem of the tension rib plates in the water-cooling environment is prevented, the problems of incomplete water leakage and maintenance of the pipeline welding seams in the industry are solved completely with the simplest method, meanwhile the consumption of spare parts can be lowered, and safe and smooth production is ensured.
