Abstract
Description
Technical Field
[0001] This utility model belongs to the field of energy dissipation well technology, specifically relating to an energy dissipation well with a short construction period. Background Technology
[0002] The principle of an energy dissipation well is that aerated water flows from the pipeline into the well, tumbling and colliding to dissipate energy. Energy dissipation wells reduce the impact of water pressure on the pipeline walls, extending the pipeline's lifespan. Most existing energy dissipation wells are concrete structures. Concrete structures require on-site formwork, resulting in long construction periods and difficulties in controlling construction quality. Furthermore, concrete energy dissipation wells have thick walls and occupy a large area, making them unsuitable for narrow alleys or areas with limited space. Some energy dissipation wells use pebbles at the bottom for protection; however, over time, various impurities and contaminants may accumulate in the pebbles, affecting their physical properties. The accumulation of impurities and contaminants on the surface and in the crevices of the pebbles can lead to blockages, thus affecting the energy dissipation effect. Utility Model Content

[0023] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0024] Example 1
[0025] like Figure 1 and Figure 2As shown, an energy dissipation well with a short construction period includes a well base 1, a well cylinder 2, a first well cover 3, an inlet pipe 4, an outlet pipe 5, a buffer assembly 6, and a second well cover 7. The well base 1 is a cylindrical shape with an open top and a well diameter of OD603. The well base 1 is made of PPB (block copolymer polypropylene) material with a ring stiffness greater than or equal to 4kN / m. 2 The well shaft 2 is a cylindrical shape with openings at both the top and bottom. The well shaft 2 is detachably connected to the well base 1. The upper end of the well base 1 is provided with a socket sleeve 11, which is integrally connected to the well base 1. The lower end of the well shaft 2 is inserted into the socket sleeve 11. A rubber ring is also provided on the outer circumference of the lower end of the well shaft 2. When the well shaft 2 is inserted into the socket sleeve 11, the rubber ring is located between the well shaft 2 and the socket sleeve 11, providing a sealing effect. The well shaft 2 is made of HDPE (high-density polyethylene) material. Well shafts of different heights can be selected according to the needs of the construction site. The first well cover 3 is placed on the well shaft 2. The first well cover 3 is a circular cover made of high-polymer composite material with a load-bearing capacity rating of B125 and a maximum allowable live load of 10kN / m. 2 The second manhole cover 7 is located above the first manhole cover 3 and has a gap between them. The circular edge of the second manhole cover 7 is located on the surrounding ground, and the weight of the second manhole cover 7 is borne by the surrounding ground. The second manhole cover 7 is made of steel fiber reinforced concrete with a load-bearing capacity of C250. The inspection method and inspection standard for the manhole cover refer to "Inspection Manhole Cover GB / T23858-2009", which can effectively protect the first manhole cover 3 and the manhole 2 below. The inlet pipe 4 is connected to the well base 1. The inlet pipe 4 includes a short pipe 41 and an elbow 42. The elbow 42 is a 90° elbow located inside the well base 1. The short pipe 41 and the elbow 42 are connected by heat fusion. The side wall of the well base 1 has a through hole corresponding to the inlet pipe 4. The inlet pipe 4 passes through the through hole, and a sealing ring 8 is fitted inside the through hole. The sealing ring 8 is a rubber ring. When the inlet pipe 4 passes through the through hole, the sealing ring 8 is fitted outside the inlet pipe 4, thereby completing the seal between the inlet pipe 4 and the well base 1. The inlet pipe 4 is used to connect to the pump station's outlet pressure pipe. The inlet pipe 4 is pre-fixed to the well base 1 before the construction of the energy dissipation well to facilitate the later construction of the connection between the end pressure pipe and the energy dissipation well. The outlet pipe 5 is integrally connected to the side wall of the well base 1. The height from the bottom of the outlet pipe 5 to the bottom of the well base 1 is set as needed. The diameter of the outlet pipe 5 is also reasonably selected and set according to different usage scenarios, ranging from DN225 to DN400.
[0026] like Figure 2 , Figure 3 and Figure 4As shown, a buffer assembly 6 is provided inside the well base 1. The buffer assembly 6 includes a storage basket and multiple pebbles 91 placed inside the storage basket. The storage basket is placed on the inner bottom wall of the well base 1. The storage basket includes a first basket body 61 and a second basket body 62. The edges of the first basket body 61 and the second basket body 62 are formed by splicing them together. In this embodiment, the first basket body 61 and the second basket body 62 are both semi-circular baskets. The two basket bodies are spliced together to form a complete circle. Three hanging columns 63 are provided on the first basket body 61 and the second basket body 62 respectively. The lower end of the hanging column 63 is connected to the bottom plate of the frame. The top end of the hanging column 63 is connected to a lifting ring 64. The lifting ring 64 is convenient to connect a hook for lifting the entire frame. The three hanging columns 63 are arranged in a triangle to facilitate the stable lifting of the entire basket body. Pebbles 91 are laid in the first basket 61 and the second basket 62 respectively, with a laying thickness of D, where D≥200mm. In this embodiment, D=200mm. The particle size of the pebbles 91 is 3-5cm. The bottom plate and side plate of the first basket 61 and the second basket 62 are provided with multiple drainage holes. The diameter of the drainage holes is smaller than the diameter of the pebbles 91. By setting drainage holes, water can flow out when the basket is lifted.
[0027] In this embodiment, when in use, the outlet end of the elbow 42 faces downward toward the cobblestone 91, and the water in the front external pipe enters the finished energy dissipation well through the inlet pipe 4, converting the kinetic energy of the water flow into potential energy, and realizing energy dissipation during the water drop process. The pebbles at the bottom prevent water from directly scouring the bottom of the well. After a period of use, the pebbles need to be removed for cleaning. A support frame is built above the energy dissipation well, and a hand-operated hoist is hung on the support frame. A steel wire rope with multiple hooks is used to hook the lifting ring 64 on the first basket 61 or the second basket 62. After keeping it stable, one of the first basket 61 or the second basket 62 is lifted out first. Then, the other basket is hooked with a steel wire rope with multiple hooks, rotated at a certain angle to avoid the upper bend 42, and then the basket is lifted out. The pebbles 91 in the basket are then taken out for cleaning and put back into the basket. The first basket 61 and the second basket 62 are then lowered and placed. Before placing the basket that is lowered into the well base 1, it is rotated at a certain angle so that it is below the bend 42, and then placed down into place. Then, the other basket is lowered and placed on the inner bottom wall of the well base 1. The basket is set in two halves so that the basket is not blocked by the bend 42 in the well base 1 when it is lifted out.
[0028] Example 2
[0029] like Figure 5As shown, the difference from Embodiment 1 is that the first basket 61 and the second basket 62 in this embodiment are not semi-circular baskets, but fan-shaped baskets. The central angle of the fan of the first basket 61 is 90°, and the central angle of the fan of the second basket 62 is 270°. When the baskets in this embodiment need to be lifted out, the first basket 61 and the second basket 62 are first lifted off the ground a short distance away, and then rotated at a certain angle so that the first basket 61 is located in an area other than directly below the bend 42. Then the first basket 61 is lifted out separately, and then the second basket 62 is lifted out and rotated at a certain angle so that the notch of the second basket 62 is directly below the bend 42. Then the second basket 62 is lifted out.
[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
