Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a method for constructing energy dissipation wells and a foundation structure for energy dissipation wells. Background Technology

[0002] In water pipelines with large drops in elevation, such as drainage, water supply, or flood discharge pipelines, it is necessary to consider eliminating the energy carried by the water flow within the structure itself. Pipelines with large drops in elevation are prone to cavitation erosion and cavitation damage. Instability in the water flow can easily generate vibration and noise, which is extremely detrimental to buildings when in a state of alternating open and full flow.

[0003] Energy dissipation wells are devices that reduce the kinetic energy of water flow, eliminating most of the energy within the pipeline or structure during the water drop process. Specifically, energy dissipation wells safely dissipate the potential and kinetic energy of water flow within a small space and short distance. Under normal circumstances, they ensure proper connection between upstream and downstream water flow, preventing overflow. They also take into account the destructive effects of water flow such as cavitation, pulsation, vibration, abrasion, and scouring, ensuring the safety and durability of water pipelines, energy dissipation structures, and urban pipe networks, and enabling the normal and orderly operation of urban water supply.

[0004] Existing energy dissipation wells have limited energy dissipation effects and cannot be easily matched with specific scenarios. They cannot be modified after construction is completed, and if the design plan cannot be finalized in time, construction can only be carried out after the finalization. It is impossible to reserve the well channel for subsequent construction, which leads to delays in the construction period.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Existing energy dissipation wells have limited energy dissipation effects and cannot be easily matched with specific scenarios. They cannot be modified after construction is completed, and if the design plan cannot be finalized in time, construction can only be carried out after the finalization. It is impossible to reserve the well channel for subsequent construction, which leads to delays in the construction period.

[0056] Based on the above deficiencies, this application provides Embodiment 1, specifically an energy dissipation well foundation structure, to solve the above deficiencies.

[0057] Specifically, such as Figure 1 This is a structural schematic diagram of panel 1, as shown below. Figure 2 This is a schematic diagram of energy dissipation well units stacked in a vertical shaft. It shows that the basic structure of this energy dissipation well includes several plates 1, each plate 1 having several through holes 1-1. The plates 1 are made of steel plates and are arranged in the vertical shaft 20, evenly distributed along the central axis of the vertical shaft 20. When rainwater enters the energy dissipation well, it encounters the plates 1, and after some of its potential energy is eliminated by the plates 1, it continues to fall through the through holes 1-1, thereby reducing the potential energy of the rainwater and achieving the energy dissipation effect.

[0058] Furthermore, since buildings in different regions have different water flow sizes, and buildings in different orientations have different angles at which water flow impacts plate 1, the optimal energy dissipation angle of plate 1 will also vary. Therefore, the optimal angle of plate 1 will also vary. Thus, the foundation structure of this energy dissipation well is also set such that plate 1 and the central axis of the vertical shaft 20 are set at an angle. The specific angle can be changed according to the specific application scenario, which has the technical advantage of being simple and easy to implement and matching the energy dissipation effect with the specific scenario.

[0059] Furthermore, such as Figure 2 , and such Figure 3 —This is a structural schematic diagram of the energy dissipation well unit. In order to avoid delays in the construction period if the design scheme cannot be finalized in time, the basic structure of this energy dissipation well also includes several energy dissipation well units. The energy dissipation well units are arranged in the vertical shaft 20 along the central axis of the vertical shaft 20 to assist in the installation of the plate 1. Several plates 1 are placed one by one in several energy dissipation well units. When the design scheme cannot be finalized in time, it is only necessary to reserve the vertical shaft 20 and then stack the plate 1 and the energy dissipation well units in the vertical shaft 20, thus avoiding the defects of delaying the construction period.

[0060] Furthermore, such as Figure 3 The energy dissipation well unit specifically includes a cylindrical structure 2 with openings at both ends. The plate 1 is placed inside the cylindrical structure 2 and is set at an angle to the central axis of the cylindrical structure 2. In this embodiment, the cylindrical structure 2 is specifically a square cylindrical structure, which is welded from four steel plates. The openings at both ends are used to connect with other cylindrical structures 2 to form a complete energy dissipation well.

[0061] Furthermore, the connection method between plate 1 and column structure 2 is as follows: (e.g.) Figure 3 This indicates that the energy dissipation well unit also includes a vertical connecting plate 16, which is a steel plate and is set against the inner wall of the column structure 2. One end of the plate 1 is connected to the vertical connecting plate 16 by a first hinge 17; Figure 4 The diagram shows a detail of energy dissipation well unit A, indicating that the unit also includes a first connecting plate 3, which is also made of steel and is perpendicular to the inner wall of the column structure 2. The plate 1 and the first connecting plate 3 are connected by a second hinge 18. The energy dissipation well unit also includes bolts 4 and nuts 5. One end of the bolt 4 is connected to the inner wall of the column structure 2, and the other end extends into the first waist-shaped hole 3-1 on the first connecting plate 3 and is screwed to the nut 5. In this way, the angle of the plate 1 can be adjusted by the connection position of the bolt 4 and the first waist-shaped hole 3-1, so that the plate 1 can match the energy dissipation effect with the specific scene, and the energy dissipation effect can be changed after the building is completed.

[0062] Specifically, the angle of plate 1 is adjusted as follows: apply force to the first connecting plate 3 to make the first connecting plate 3 move vertically, which causes the tilt angle of plate 1 to change. After the adjustment is completed, the first connecting plate 3 moves horizontally at the same time. At this time, the relative position of bolt 4 and the first waist-shaped hole 3-1 changes. Then, the first connecting plate 3 can be locked.

[0063] Furthermore, the connection method between the first connecting plate 3 and the column structure 2 is specifically as follows: Figure 4 The energy dissipation well unit also includes a second connecting plate 7, which is placed inside the column structure 2 and is perpendicular to the inner wall of the column structure 2. It is fixedly connected by screws 19, and bolts 4 pass through the second connecting plate 7 and the first connecting plate 3 in sequence, and are screwed to nuts 5.

[0064] Furthermore, when plate 1 is subjected to rainwater impact, it also suffers wear and tear. Therefore, plate 1 needs to be given a certain degree of flexibility to allow it to absorb some of the pressure. Figure 4 The energy dissipation well unit also includes an elastic element 6. One end of the elastic element 6 abuts against the first connecting plate 3, and the other end abuts against the second connecting plate 7. When the plate 1 is subjected to pressure, the force is transmitted to the elastic element 6, and the elastic element 6 undergoes a certain elastic deformation to offset part of the pressure on the plate 1, thereby improving the service life of the plate 1.

[0065] Furthermore, such as Figure 4 The elastic element 6 is specifically a disc spring, which is pierced by bolt 4. When it is necessary to adjust the tilt angle of plate 1, the number of disc springs can be placed as needed to adjust the first connecting plate 3 to the target height.

[0066] Furthermore, in order to further increase the stability of plate 1, such as Figure 3 The energy dissipation well unit also includes a first rivet 9, one end of which is connected to the plate 1 near the end of the first connecting plate 3, and the other end passes through the second oblong hole 2-1 provided on the column structure 2 and is fixed by the first rivet nut 9-1; it also includes a second rivet 10, one end of which is connected to the plate 1 near the end of the second connecting plate 7, and the other end passes through the third oblong hole 2-2 provided on the column structure 2 and is fixed by the second rivet nut 10-1; this arrangement can further stabilize the plate 1, reduce the shaking at the connection points of the plate 1 with the vertical connecting plate 16 and the first connecting plate 3, and also increase the service life of the plate 1. At the same time, the setting of the second oblong hole 2-1 and the third oblong hole 2-2 provides flexible space for the plate 1 to transmit pressure to the elastic member 6.

[0067] Furthermore, in order to remotely monitor whether panel 1 is in a good energy dissipation state over a long period of time, so as to make adjustments after the building is completed, such as... Figure 4 The energy dissipation well unit also includes a distance sensor 8, which is placed on the second connecting plate 7 and points towards the first connecting plate 3. When the tilt angle of the plate 1 changes and the change exceeds the normal elastic space, the distance between the first connecting plate 3 and the second connecting plate 7 will exceed the preset value, indicating that the energy dissipation well has malfunctioned or aged and needs to be repaired.

[0068] Furthermore, such as Figure 3 The energy dissipation well unit also includes a connecting flange 11, which is located at the open end of the column structure 2 and is used to connect with other energy dissipation well units.

[0069] Furthermore, to facilitate the stacking and installation of the energy dissipation well units, the basic structure of this energy dissipation well also includes a vertical track 12. In this embodiment, as shown... Figure 2 The vertical track 12 consists of four angle steels, which are installed inside the shaft 20 and arranged along the extension direction of the shaft 20. The bottom ends of the angle steels are fixed inside the shaft 20 with screws to guide the stacking and installation of the energy dissipation well units. It also includes opening groups 13, several of which are arranged along the extension direction of the shaft 20. Each opening group 13 includes four openings, which are formed on the shaft wall of the shaft 20. Each opening group 13 corresponds to the connection points between two energy dissipation well units. Figure 5 ,for Figure 2 The top sectional view shows that the foundation structure of this energy dissipation well also includes several positioning rods 15, which are also angle steels, arranged along the extension direction of the vertical shaft 20. Each positioning rod 15 is supported by the opening and is used to fix it to the opening, and is also used to connect to the connecting flange 11 on the energy dissipation well unit, thereby realizing the fixing function of the energy dissipation well unit.

[0070] Furthermore, such as Figure 2 The basic structure of this energy dissipation well also includes a pad 14, which is placed at the bottom of the vertical shaft 20 along the vertical track 12 to make the first energy dissipation well unit correspond to the bottommost opening group 13.

[0071] Based on the above deficiencies, this application also provides Embodiment 2, specifically an optimal solution for the construction method of an energy dissipation well, to assist in the construction of an energy dissipation well foundation structure in Embodiment 1, specifically including the following steps:

[0072] S1. When forming the vertical shaft 20, several sets of opening groups 13 are reserved so that each set of opening groups 13 includes four openings, and bolts are pre-embedded in each opening.

[0073] S2. Install vertical rails 12 and pads 14 inside the shaft 20. Specifically, set up four angle steels parallel to each other along the direction of the shaft 20, fix their bottom ends inside the shaft 20, and lower the pads 14 along the angle steels to the bottom so that the upper end face of the pads 14 corresponds to the first set of openings 13.

[0074] S3. Adjust the included angle of the plate 1 in each energy dissipation well unit. Specifically, unscrew the nut 5 to drive the first connecting plate 3 to move up and down, while increasing or decreasing the number of elastic elements 6 (disc springs) until the plate 1 is at a suitable tilt angle, then tighten the nut 5 onto the bolt 4.

[0075] S4. Hoisting the energy dissipation well unit. Specifically, using the hoisting device, the first energy dissipation well unit is placed on the pad 14 from the position of the vertical shaft 20, so that the connecting flange 11 at the bottom of the energy dissipation well unit corresponds to the first group of openings 13, and the connecting flange 11 at the top corresponds to the second group of openings 13. Then, the second energy dissipation well unit is hoisted and placed on the first energy dissipation well unit, until all energy dissipation well units are hoisted.

[0076] S5. Fix the energy dissipation well unit. Specifically, install two positioning rods 15 at each opening group 13, so that the openings at both ends of the positioning rod 15 are connected to the positioning rod 15 by pre-embedded bolts, and the positioning rod 15 is connected to the connecting flange 11 of the energy dissipation well unit by self-tapping screws. At the same time, the connecting flange 11 of two adjacent energy dissipation well units is also connected by screws.

[0077] S6. Disassemble the vertical rail 12 and the pad 14, that is, disassemble the vertical rail 12 and the pad 14 after they have completed their guiding function;

[0078] S6. Pour concrete into the gap between the energy dissipation well unit and the vertical shaft 20, and carry out masonry sealing work to form an energy dissipation well.
