Technical field
The present invention relates to reclaim fields from the sea engineering, mariculture engineering, seawater of the coastal beach and the shallow water along the coast and promote and utilize engineering, environmental reconstruction engineering, strand city construction engineering, relate in particular to a kind of high-order overflow weir seawater one-way flow engineering.
Background technology
Utilize coastal beach and shallow water along the coast development mariculture, reclaim fields from the sea and build the city, strand at husky muddy coast, generally face the problem of water body exchange difficulty.Especially utilizing beach to do the mariculture prior art all is to build the water lift pumping plant, relies on the electric pump water lift that the water body exchange is carried out in the mariculture zone, and this mode can be proved effective to a certain extent, but exists following shortcoming or deficiency: 1. consume worker's time consumption and energy consumption; 2. need to build the water lift pumping plant, it is numerous and diverse to purchase work such as erection equipment, operational management, maintenance of equipment; 3. a large amount of power consumptions, the aquaculture cost height.
Summary of the invention
The purpose of this invention is to provide a kind of high-order overflow weir seawater one-way flow engineering, do not need the water lift pumping plant, adopt high-order overflow weir to form the mode of Na Chaoshuiku, the skilful use tidal range realizes that the seawater one-way flow solves water body and exchanges problem.Cross overflow weir after high tide reach a certain height and enter Na Chaoshuiku, receive seawater in the tidewater storehouse and just must enter the water reticulation system one-way flow and satisfy the needs that exchange water body, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art as long as the water surface is lower than overflow weir at ebb tide by sluice.
High-order overflow weir seawater one-way flow engineering of the present invention, comprise high-order overflow weir, Na Chaoshuiku, intake gate or inlet culvert, the water delivery trunk canal, anti-tide dike, the branch line water channel, drainage gate, arterial drainage, rock revetment, it is characterized in that building anti-tide dike and high-order overflow weir and forming Na Chaoshuiku at the coastal beach and the shallow water along the coast, the crest level of described high-order overflow weir, be lower than local at the incoming tide high water line, be higher than local at ebb tide low tide waterline, high-order overflow weir is a reinforced concrete slab diaphragm wall structure, Na Chaoshuiku is by forming after high-order overflow weir and the anti-tide dike corral, Na Chaoshuiku is provided with intake gate or the inlet culvert that is connected with the water delivery trunk canal, the water delivery trunk canal is connected with the branch line water channel, and the arterial drainage of anti-tide dike is provided with drainage gate.
Wherein, reinforced concrete slab one side of described high-order overflow weir diaphragm wall is embedded with the insert of T type or i shaped steel making, opposite side is embedded with the plug-in unit that is subjected to of hollow square steel making, at insert and be subjected to the plug-in unit both sides to be reserved with semicircle Baltimore groove, be vertically arranged with water-supply-pipe in the reinforced concrete slab, the bottom is arranged with the discharge jet that is connected with water-supply-pipe in parallel with reinforced concrete slab, and the discharge jet bottom is drilled with the jetting hole of 2-12 millimeters of diameters.Described reinforced concrete slab is prefabricated on land, insert the stratum by special construction apparatus, both sides form rock revetment, at the Baltimore groove of reinforced concrete slab be subjected to be lowered in the plug-in unit grouting pipe and inject cement paste, make and insert the stratum and disperse the reinforced concrete slab of monolithic to become integrally-built marine steel bar concrete diaphragm wall.The actual conditions of determining to take into full account local tidal range variation of described high-order overflow weir crest level, should satisfy most duration of tide seawater and can cross the needs that high-order overflow weir enters Na Chaoshuiku, the chance that satisfies again that flood tide is each time received the needs that the tidewater storehouse can more than enough some seawater of savings.The described size of receiving tidewater storehouse area needs to determine with seawater quantity according to reality.Described drainage gate is arranged on the arterial drainage of anti-tide dike.Described high-order overflow weir enters the seawater of Na Chaoshuiku, enters water delivery trunk canal, branch line water channel or mariculture place by intake gate or inlet culvert at ebb tide, enters arterial drainage at last and flows into the sea from drainage gate.The inboard in anti-tide dike is constructed in described water delivery trunk canal.
The present invention has following advantage compared with prior art:
1, energy conservation and consumption reduction effects is obvious.Coastal area development mariculture carries out water body exchange and strand urban construction, realizes the seawater one-way flow by high-order overflow weir skilful use tidal range, replaces the electric pump water lift and have significant advantage aspect energy-saving and cost-reducing.
2, operational management is simple.The water inlet automatically of twice rising tide every day flows into the network of rivers automatically and carries out the water body exchange, and operational management is simple and convenient.
3, improve the environment looks, also created condition simultaneously for going sightseeing.Water quality in the city river of strand is bad to be a common problem, realizes that by high-order overflow weir skilful use tidal range this situation of seawater one-way flow will thoroughly change.Seawater is crossed overflow weir and is formed roomy waterfall group at the incoming tide, flowing water speed is constantly accelerated to utilize water channel can carry out the Drifting activity at ebb tide, whole water reticulation system is communicated with the leisure fishing place that provides good with the off-lying sea, realize the seawater one-way flow by high-order overflow weir skilful use tidal range, for the city, strand of built environment grace lays the first stone.
