Problems solved by technology

However, only steel fibers distributed horizontally or approximately horizontally can effectively increase the shear strength of manhole covers in the application of manhole covers, so the effective utilization of steel fibers in traditional steel fiber reinforced concrete manhole covers is very low, which will lead to Increased Cost of Steel Fiber Concrete Manhole Covers

Abstract

The invention discloses a directional steel fiber reinforced concrete square well lid prefabricating device and a manufacturing method. The directional steel fiber reinforced concrete square well lidprefabricating device comprises a lower template, an upper template, a first semi-magnetic field box, a second semi-magnetic field box, a bolt, a first template clamping groove, a first template buckle and a directional magnetic field box; the directional magnetic field box comprises the first semi-magnetic field box and the second semi-magnetic field box; a containing area is arranged inside thelower template; threaded holes are formed in two sides of the lower template; and second template clamping grooves are formed in tops of two sides of the lower template. The advantages of high strength, corrosion resistance, low recycling value, easy and convenient manufacturing and the like of concrete well lids are retained, and the shear strength of steel fiber reinforced concrete well lids isalso effectively improved, or the quantity of steel fibers used for reaching the same shear strength as the steel fiber reinforced concrete well lids is reduced.

Description

technical field [0001] The invention relates to the technical field of building facilities, in particular to a prefabricated device and a manufacturing method for a directional steel fiber concrete square manhole cover. Background technique [0002] With the acceleration of my country's urbanization process, the development speed of supporting facilities required for urbanization has also been greatly improved. Among them, manhole covers are used to cover deep road wells and are widely used in cities. Whether it is water wells, communication wells, gas wells, etc., manhole covers need to be used, so the manhole covers need to carry the vehicles on the top and pedestrians to pass to protect the pipeline equipment in the deep well. , It is also necessary to ensure the simplicity of its transportation and installation. Therefore, how to choose appropriate materials and production methods, and reduce the cost and amount of materials as much as possible under the premise of ensur...
