Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a three-row device applied to an arc-shaped riprap concrete structure. Background Technology
[0002] After rubble is placed into a rubble silo, concrete is poured to form a rubble concrete structure. The silo is typically cubic, and self-compacting concrete can fill the gaps between the rubble. Before placing the rubble, the silo needs to be cleaned, including flushing to remove water and mud, before pouring concrete to form the rubble concrete structure. How to effectively drain and remove mud is a challenge in this field. Furthermore, when the silo is adjacent to the dome of a silo, forming an arc-shaped silo, the outer surface of the arc-shaped structure tapers inwards. During concrete pouring, gas and air bubbles generated during condensation tend to accumulate inside the arc-shaped silo, affecting the concrete density and causing voids and holes, thus reducing the construction quality of the arc-shaped rubble concrete structure. Utility Model Content
[0003] The purpose of this invention is to provide a three-row device for use in curved riprap concrete structures, in order to solve the problem of poor construction quality in curved riprap concrete structures.
[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a three-row device applied to an arc-shaped riprap concrete structure, including a tubular body inserted into a soil membrane set outside the arc-shaped riprap silo, with both ends of the tubular body protruding from the soil membrane and extending into the soil below the soil membrane, respectively. The lower end of the tubular body is lower than the bottom surface of the arc-shaped riprap silo, and a connecting pipe is inclined downward along the arc-shaped riprap silo towards the tubular body and connected between the arc-shaped riprap silo and the tubular body.
[0005] Furthermore, in the three-row device for use in arc-shaped riprap concrete structures provided by this utility model, the tubular body is a corrugated pipe.
[0006] Furthermore, in the three-row device for use in arc-shaped riprap concrete structures provided by this utility model, the corrugated pipe is a steel pipe.
[0007] Furthermore, in the three-row device for use in arc-shaped riprap concrete structures provided by this utility model, the tubular body is a round tube or a square tube.
[0008] Furthermore, in the three-row device for use in arc-shaped riprap concrete structures provided by this utility model, the connecting pipe is a circular pipe.
[0009] Furthermore, in the three-row device for use in arc-shaped riprap concrete structures provided by this utility model, the circular tube is a steel pipe.
[0010] Furthermore, the three-row device provided by this utility model for use in arc-shaped rockfill concrete structures has the tubular body vertically inserted into the soil membrane set outside the arc-shaped rockfill silo and extending into the soil.
[0011] Furthermore, the three-row device provided by this utility model for use in arc-shaped rockfill concrete structures has the tubular body inserted obliquely into the soil membrane set outside the arc-shaped rockfill silo and extending into the soil.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] The three-row device provided by this utility model, applied to arc-shaped riprap concrete structures, discharges wastewater and sludge generated during the flushing and cleaning of the arc-shaped riprap silo through connecting pipes and tubular bodies to the outside of the silo, preventing the accumulation of wastewater and sludge inside. During the concrete pouring process after the riprap is placed inside the arc-shaped riprap silo, the gas generated inside the silo and the air bubbles generated during concrete setting are discharged outside through connecting pipes and tubular bodies, preventing the accumulation of gas and air bubbles inside the silo during concrete pouring, which could affect the density of the concrete and cause problems such as cavities and voids. This device solves the technical problems of drainage, sludge removal, and air release during the construction of arc-shaped riprap concrete structures in one go, improving the construction quality of the arc-shaped riprap concrete structures.

[0017] The present invention will now be described in detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.
[0018] Please refer to Figure 1During the construction of the silo, the silo dome 201 is an arc-shaped structure. Therefore, the rockfill silo enclosed by the silo dome 201, the reinforced concrete 206 of the silo, and the soil formwork 204 is also arc-shaped, and is called an arc-shaped rockfill silo. The soil formwork 204 is constructed on the soil 204 outside the silo dome 201. After the rockfill is placed inside the arc-shaped rockfill silo, concrete is poured to form the arc-shaped rockfill concrete structure 202. To prevent structural deformation of the arc-shaped rockfill concrete structure 202, wire mesh 203 is installed on its outer contour surface.
[0019] Please refer to Figure 1 This utility model provides a three-row device for use in an arc-shaped riprap concrete structure, including a tubular body 101 inserted into a soil membrane 204 located outside the arc-shaped riprap silo. The two ends of the tubular body 101 protrude from the soil membrane 204 and extend into the soil 205 below the soil membrane 204, respectively. The lower end of the tubular body 101 is below the bottom surface of the arc-shaped riprap silo. A connecting pipe 102, inclined downwards along the arc-shaped riprap silo towards the tubular body 101, connects the arc-shaped riprap silo and the tubular body 101. The tubular body 101 can be a round or square pipe, etc., and the connecting pipe 102 can be a Φ60mm round pipe, with a 60° joint between the connecting pipes 102. To reduce costs, the tubular body 101 can also be a Φ300mm corrugated pipe, which also has the advantage of convenient construction. To improve service life, both the tubular body 101 and the connecting pipe 102 can be made of steel pipe. The connecting pipe 102 is inclined downwards along the arc-shaped rockfill silo towards the tubular body 101 to prevent backflow.
[0020] The three-row device for arc-shaped riprap concrete structures provided in this embodiment of the invention discharges wastewater and sludge generated during flushing and cleaning of the arc-shaped riprap silo through the connecting pipe 102 and the tubular body 101 to the outside of the arc-shaped riprap silo, preventing the accumulation of wastewater and sludge inside the silo. During the pouring of self-compacting concrete after the riprap is placed inside the arc-shaped riprap silo, the gas generated inside the silo and the air bubbles generated during concrete setting are discharged outside the silo through the connecting pipe 102 and the tubular body 101, preventing the gas and air bubbles generated during concrete pouring from accumulating in the cavity and affecting the density of the concrete, causing cavities and voids. This solves the technical problems of drainage, sludge removal, and air release during the construction of the arc-shaped riprap concrete structure 202 in one go, improving the construction quality of the arc-shaped riprap concrete structure. The arc-shaped rockfill silo and the tubular body 101 form a communicating vessel via a connecting pipe 102. This allows for effective drainage and sludge removal when flushing the inner surface of the arc-shaped rockfill silo, and effective venting during the pouring process. The three drainage functions refer to drainage, sludge removal, and venting. To completely remove wastewater, sludge, and air bubbles from the arc-shaped rockfill silo, the slope of the connecting pipe 102 is i = 0.02.
[0021] The three-row device provided in this embodiment of the utility model, applied to the arc-shaped riprap concrete structure, allows for simple subsequent processing operations after the completion of the arc-shaped riprap concrete structure construction by backfilling the tubular body 101. This does not affect the next stage of construction and is simple and effective.
[0022] Please refer to Figure 1 To discharge wastewater, sludge, gas, and bubbles from the arc-shaped rockfill silo, this embodiment of the invention provides a three-row device for use in arc-shaped rockfill concrete structures. The tubular body 101 is inserted vertically or obliquely into the soil membrane 204 located outside the arc-shaped rockfill silo and extends into the soil 205. When the tubular body 101 is inserted obliquely, it can form an obtuse angle with the connecting pipe 102, facilitating the discharge of wastewater, sludge, gas, and bubbles.
