The specific embodiment
Take certain pond engineering is below example, and the invention will be further described, this rectification wall thickness 600mm, and bottom is connected with level board, high 16.4m, degree of gravity vertical forwall surface is not more than 1/600, and its Specific construction step is as follows:
The bed die of concrete precast block encloses purlin by panel and steel and forms, and described panel is the set shaped steel formwork that is provided with circular pit, and the setting of circular pit is arranged consistent with the steel pipe of pressure piercing wall building block.As wide according to rectification wall, a certain layer concrete prefabricated section is determined in designing requirement is 3850mm, and height is 2880mm, and its panel size is that 3880mm (wide) * 2480 mm(is high), the diameter of circular pit is 50mm.Described steel column is stairstepping and the through hole that is provided with diameter 14mm along axis, its steel column is of a size of 50mm(external diameter) * 602mm(is high) and 30mm(external diameter) * 100mm(is high), the 50mm diameter end of steel column is arranged in circular pit by tie rod (φ 12) and nut and panel and fixes, then by 50mm(internal diameter) * 600mm(is high) steel pipe socket on steel column, the center of circle of circular pit overlaps with the center of circle that completes the steel pipe of installation.
Bed die is respectively being arranged 2 channel-section steels (［ 10) and steel plate along cross direction, channel-section steel (［ 10) length is 3850mm, and steel plate is 3850mm * 48mm * 15mm (long * wide * thick).Along pressure piercing wall building block short transverse, arrange that as enclosing purlin, channel-section steel length is 2880mm to 4 channel-section steels (［ 10), channel-section steel spacing is respectively 1150mm, 1440mm and 1160mm.2 channel-section steels that enclose purlin and panel and arrange with broad ways (10) welding.
Built-in fitting is " U " shape steel plate that biside plate and end plate form, on biside plate, according to the layout of steel pipe and main muscle in the building block of pressure piercing wall, offer perforation, make steel pipe and main muscle can pass " U " shape steel plate of built-in fitting, the main muscle of pressure piercing wall building block short transverse and built-in fitting welding, reinforcing bar on its width stretches out body of wall, and reserved welding point.
" U " shape steel plate is arranged on to the two ends of bed die, spot welding channel-section steel on built-in fitting end plate ([10) is increased two side templates as concrete precast block top and bottom, all the other both sides are by veneer formwork erection, it is highly 600mm, the lumps of wood and to wearing the tie rod reinforcing bar that fixedly broad ways is arranged through template, template reserved steel bar installing hole.
Adopt layering blanking to be cast in above-mentioned formwork erection concrete, the about 300mm of every bed thickness vibration compacting, while vibrating, must not touch steel pipe, building the laggard pedestrian's work of end wipes one's face, the height of wiping one's face is concordant with steel pipe nozzle, and the demoulding after maintenance reaches design strength, first removes the wooden form of two sides during the demoulding, channel-section steel using end face as template cuts off again, finally removes bed die and takes out prefabricated pressure piercing wall building block.
The pressure piercing wall building block that above-mentioned height is not waited is separately positioned on the level board of inlet passage and water outlet gallery corresponding spacing, the building block of pressure piercing wall is laterally that steel concrete is connected with level board and cast-in-place column, and its longitudinal both sides are welded into integrally-built rectification wall by the built-in fitting of " U " shape steel plate at steel plate and two ends.Rectification wall assembled relates to the vertical partition wall of water-in and water-out gallery, the construction of level board, interconnects, and be partly connected with water-in and water-out gallery by level board between each pressure piercing wall building block by vertical partition wall and level board.For keeping the globality of Inlet and outlet water gallery, reduce construction parting, by the level board of every layer and corresponding pool wall monobloc cast construction.
The present invention is assembled into integrally-built rectification wall by some prefabricated pressure piercing wall building blocks, and when fluid flows through the perforated pipe of these intensive layouts on rectification wall, most of energy is consumed, and reaches and makes the uniform rectification effect of flow velocity.And prior art is mainly from making stream performance indications angle, for making flow point number of plies amount and gradient, to aspects such as interval size, water delivery gallery angle and size, flow field uniformity and turbulent flow controls, set about the research of hydraulics aspect, from the concrete enforcement angle of engineering, do not consider how to meet this series of requirements.Rectification wall construction of the present invention has well met and uniformly this kind of particular requirement of flowing pressure, has construction speed fast, makes, easy for installation, and operating efficiency is high, the advantage that engineering cost is low, and what be particularly useful for ocean deepwater pond makes ripple commutation system.
More than just the present invention is further illustrated, and not in order to limit this patent, all is the present invention's equivalence enforcement, within all should being contained in the claim scope of this patent.
