5results about How to "Improve landscape" patented technology

This invention provides a construction method for an ecological open channel system in urban streets and alleys, including steps such as constructing a sedimentation and filtration system, constructing a rainwater and sewage diversion system, and constructing a water resource collection system. This invention can achieve multiple benefits, including reducing urban flooding, improving the urban microclimate, and enhancing the urban landscape.

The invention discloses an urban water area sewage purification device, and belongs to the technical field of sewage treatment, the urban water area sewage purification device comprises a cylinder, the top of the cylinder is provided with an access cover, the side wall is connected with a water inlet pipe and a water outlet pipe, the water inlet is connected with a grating assembly, and the grating assembly is provided with a chemical agent supply mechanism; at least two submersible pumps are installed at the bottom in the barrel, the output ends of the submersible pumps are connected with pressure pipelines, and control valves and check valves are arranged on the pressure pipelines. An intelligent control cabinet is integrated on the top of the barrel and electrically connected with the liquid level sensor and the submersible pump. The grating assembly is arranged at the water inlet, large-particle impurities in sewage can be effectively intercepted, the impurities are prevented from entering the cylinder to block a pressure pipeline or abrade a submersible pump, the equipment fault occurrence rate is remarkably reduced, and the service life of the device is prolonged; meanwhile, the grid assembly and the chemical agent supply mechanism are arranged cooperatively, so that the agent can be fully mixed with the sewage subjected to preliminary filtration, the reaction efficiency of the agent is improved, and the subsequent purification effect is enhanced.

The utility model provides a kind of gravity type sustainable ecological retaining wall design structure belongs to geotechnical engineering technical field, comprising: waterproof unit, wall, support unit, spray layer and irrigation unit;The waterproof unit, support unit, irrigation unit and spray layer are all set on the wall;The waterproof unit is used to prevent the wall from seepage;The support unit is used to ensure the stability of the wall;The spray layer is used to enhance soil stability;The irrigation unit is used to ensure the moisture required for spray layer vegetation growth.The utility model adopts above-mentioned a kind of gravity type sustainable ecological retaining wall design structure, the structure not only has retaining function, but also can realize automatic collection of rainwater, irrigation, while increasing greening in wall body, enhance ecological benefits.

The utility model discloses a kind of pedestrian bridge truss type flange girder structure, including the girder in middle part and the flange in the both sides of girder, flange bottom is successively provided with truss integrated with flange, girder and flange lower stiffening rib along bridge length direction, truss formed by diagonal bracing and cross bracing forms continuous space triangle stable structure in plane and elevation, endows structure multilayer space change. Break traditional part flange stiffening rib adjustment to flange upper surface and cover with concrete pavement layer, avoid stiffening rib and truss interlaced, reduce construction difficulty, also have good landscape effect under meeting structural stress characteristics.

The invention provides an intelligent design method and a T-shaped wave-resistant retaining wall. The method comprises the steps that a footpath area located on the periphery of a riverway is determined, and all installation point positions corresponding to all T-shaped wave-resistant retaining walls are determined in the footpath area; wave height acquisition graphs corresponding to the installation point positions are obtained based on different acquisition moments, and the retaining wall heights of the T-shaped wave-resistant retaining walls corresponding to the installation point positions are determined based on the wave height acquisition graphs; based on the irradiation areas corresponding to the street lamps located in the footpath area, the containing attributes corresponding to the containing groove positions of the T-shaped wave-resistant retaining walls are determined, and the containing attributes comprise the green plant attribute and the lamp attribute. The practicability of the T-shaped wave-resistant retaining wall is at least improved.
