The present invention relates to a hollow cavity member for hollow plate. It includes hollow cavity forms and structural baseplate. The hollow cavity forms and structural baseplate are connected intowhole body, on the structural baseplate at least more than two hollow cavity forms are alternatively arranged, and the alternative hollow cavities between the hollow cavity forms and the structural baseplate are formed into the poured-in-place structure inner rib mould cavities. It is characterized by that in every described inner rib mould cavity at least a bracing component is set. Said invention also provides the concrete structure of the hollow cavity form and structural baseplate and their concrete connecting mode.

Disclosed is a die component, which comprises an opening die (1), characterized in that at least two opening die (1) are alternately arranged, at least one brace piece (2) connects them with each other, the opposite side faces of the opening die (1) form at least one on-site casting structure inner rib die cavity (3), while the other outer side faces form the side die plate of on-site casting structure outer rib, beam or wall. In floor construction with said opening die component, it is convenient for arrangement and positioning, easy to guarantee the construction quality, and also has the characteristics of high strength, easy making, low cost, etc. The invention is suitable for hollow floor, roof, soleplate, wall and bridge with on-site casting reinforced concrete or prestressed reinforced concrete, especially for hollow mushroom floor.

The invention discloses a method for processing agricultural running water pollution by utilizing bank and a compound system for processing running water pollution. A multi-level infiltration bed is constructed at the lower end of an agricultural running water converging channel along the bank from top to bottom, and consists of aquatic plants at the upper part and fillers at the lower part, a sand settling-buffering tank is arranged in front of each level of infiltration bed for settling sand, after the sand settling process, running water enters the infiltration bed for infiltration process, and the running water processed by a multi-level sand settling-infiltrating system is finally discharged into soil or water body by a water outlet area at the tail part of the system. In the invention, the bank is fully utilized for buffering water flow impact, water inlet quality is homogenized, and the purifying effect of running water pollutant is improved. Besides the traditional advantages of simple construction, convenience in operation and management, low cost and the like, the invention also has the advantages of no energy consumption, difficult blockage, small investment, convenience in operation and management, and strong anti-impact and anti-load capability.

The present invention relates to a hollow cavity member for hollow plate. It includes hollow cavity or solid forms and structural baseplate. The hollow cavity or solid forms and structural baseplate are connected into a whole body, on the structure baseplate at least more than two hollow cavity or solid forms are alternatively arranged, the alternative hollow cavities between the hollow cavity orsolid forms and structural baseplate are formed into cast-in-place structure inner rib mould cavities. It is characterized by that in every described inner rib mould cavity at least a bracing componentis set. The invented hollow cavity member is applicable to cast-in-place reinforced concrete or prestressed reinforced concrete hollow plate, hollow floor board, roof slab, foundation baseplate, wall body and open-web bridge.

A cavity member for hollow plate includes integrated hollow form shell and structure bottom plate, wherein at least two hollow form shells alternatively arranged on structure bottom plate, the cavity of hollow form shell and structure bottom plate forms in site casting inner rib form cavity, it featuring said inner rib form cavity having at least one support-draw piece to connect adjacent hollow form shell, the hollow firm shell arranged in same longitudinal axis, through long support-draw piece connecting at least two hollow form shell in inner rib form cavity near adjacent hollow firm shell. Said invention has fine strength, rigidity and shock resistance, can be widely used in site casting reinforced steel concrete or prestressed reinforced steel concrete hollow plate, hollow storied building cover, room cover, base bottom plate, wall, and hollow bridge.

The invention discloses a method for remedying the micro-polluted water body. The method comprises the following steps: 1) the micro-polluted water body firstly enters a first-stage water treatment area to perform sand settling and uniform water distribution; 2) the water body secondly enters a second-stage water treatment area-wetland bed, wherein the wetland bed is mainly composed of filler anda water plant, the water plant is giant reed, the filler is composed of upper filler and lower filler, the upper filler is gravel and the particle size is 5-10mm; the lower filler is the shale brick,the particle size of the shale brick is 10-60mm and the root system of the water plant grows in the filler; and 3) the water body finally enters a third-stage water treatment area to homogenize the effluent quality, and the water body can be discharged and enter the outer water body. The system has the following advantages: (1) no energy is consumed, the system is difficult to block; (2) the investment is low, the system is convenient to operate and manage; (3) the shock resistance is strong; and (4) the nitrogen-phosphorus removal rate is high and the system has a certain economic benefit.
