Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering foundation pit pipe well filling technology, and specifically proposes a construction method for water conservancy engineering foundation pit pipe well filling. Background Technology

[0002] In water conservancy projects, the backfilling of foundation pits and manholes refers to the backfilling of foundation pits and manholes during the construction of water conservancy projects to facilitate pipeline layout and maintenance. The specific backfilling process generally includes the following steps: Preliminary preparation: Ensure the backfilling area is clean and tidy → Construction preparation: Prepare the materials and equipment required for backfilling, including backfill soil, filler material, and compaction equipment → Backfilling operation: Backfill soil and filler material layer by layer and section by section inside the manhole and foundation pit → Compaction treatment: This can improve the density and stability of the backfill material → Backfill layer thickness control: Control the thickness of the backfill layer to ensure that the backfilled pipelines are adequately protected → Post-processing: Clean and tidy up the backfilling area.

[0003] However, the following problems still exist in the current process of backfilling foundation pit manholes: 1. In the process of backfilling foundation pit manholes, the traditional method is to place the manhole and then fill it directly with backfill material, and then compact it after all the backfilling is completed. This method may result in uneven compaction of the backfill material, which may create voids and unstable areas. This may affect the stability of the manhole and the load-bearing capacity of the structure. Moreover, the method of placing the manhole and then filling it directly with backfill material in one go will result in uneven settlement distribution of the filling material in different areas, which will lead to foundation imbalance and cause insufficient or excessive settlement, thereby affecting the stability of the structure.

[0004] Therefore, in order to avoid affecting the load-bearing capacity and stability of the structure when the foundation pit well is filled, the present invention provides a construction method for filling the foundation pit well in water conservancy projects. Summary of the Invention

[0005] Therefore, it is necessary to provide a construction method for backfilling wells in water conservancy projects, which aims to solve the problem of the load-bearing capacity and stability of the structure when backfilling wells in foundation pits using existing technologies.

[0009] S3. Burial Operation: Through the cooperation of the fixed and moving mechanisms, the pit in step 2 is filled layer by layer and section by section. During the burial process, the tamping component is used to tamp the burial material and control the thickness of the burial layer to ensure that the pipeline is adequately protected after burial.

On the rotating rod, a rotating gear that meshes and drives with the left and right rack plates is fixedly installed. At one end of the structural block located inside the rectangular groove, an electric telescopic rod fixedly connected to the bottom of the left moving block is fixedly installed.

[0017] According to an embodiment of the present invention, the material spreading component includes a vertical plate fixedly installed at one end of the moving block away from the fixed block.

[0022] According to the first aspect of the present invention, the cooperation of the fixing mechanism and the moving mechanism can control the filling material of the foundation pit to be filled layer by layer during the filling process of the foundation pit well. By continuously filling layer by layer, and by performing vibration operation during the filling process, the filling material can be uniformly distributed and compacted, so that the filling layer has better stability. At the same time, the continuous layer-by-layer filling method can make the filling operation more standardized, and thus the filling work can be completed more efficiently.

[0023] Furthermore, according to the isolation component provided in the second aspect of the present invention, the foundation pit that needs to be filled can be divided into sections for processing, thereby enabling regional segmented filling. Segmented filling can decompose the filling task into smaller units, making the operation simpler and more centralized, thereby improving work efficiency and reducing chaos during construction. It also prevents uneven settlement distribution of filling material in different areas, which could lead to foundation imbalance and insufficient or excessive settlement, thus affecting the stability of the structure.

[0024] Furthermore, the material spreading assembly provided in the third aspect embodiment of the present invention can spread the landfill material placed in the foundation pit back and forth, thereby avoiding the accumulation of landfill material in the corners and thus affecting the spreading effect. The balanced load distribution can improve the bearing capacity and enhance the overall stability.

Detailed Implementation

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] See Figure 1 A method for backfilling and burying manholes in a water conservancy project foundation pit, which specifically includes the following steps:

[0039] S1. Preliminary preparation: Before landfilling, it is necessary to clean and remove debris and garbage from the foundation pit and manhole.

[0040] S2. Construction preparation: Prepare the materials and equipment needed for the backfill and move them to the foundation pit after it has been cleaned in step 1.

[0041] S3. Burial Operation: Through the cooperation of the fixed mechanism 1 and the moving mechanism 2, the pit in step 2 is filled layer by layer and section by section. During the burial process, the compaction component 27 is used to compact the burial material and control the thickness of the burial layer to ensure that the pipeline after burial is adequately protected.

[0042] S4. Post-filling: After the landfill is completed, the landfill area in step 3 needs to be cleaned and tidied up.

[0043] See Figure 2 The construction method for filling and burying wells in water conservancy project foundation pits using the above steps S1-S4 also specifically involves a construction equipment for filling and burying wells in water conservancy project foundation pits during the filling and burying process. The equipment includes a fixed mechanism 1, on which a moving mechanism 2 for filling and burying water conservancy project foundation pits is provided.

[0044] See Figure 2 , Figure 3 and Figure 5 The fixing mechanism 1 includes a fixed base 11. Self-locking casters are fixedly installed at the bottom of the fixed base 11 near the four corners. A push handle 12 for controlling the movement of the fixed base 11 is provided in the middle of the left end face of the fixed base 11. A fixing plate 13 is fixedly installed on the top of the fixed base 11. A moving groove is opened on the front end face of the fixing plate 13. An extension plate 14 is slidably arranged in the moving groove. A drive assembly 15 for controlling the up and down movement of the extension plate 14 is provided on the fixing plate 13. An isolation assembly 16 for separating the water conservancy project foundation pit that needs to be filled is provided on the right end face of the fixing plate 13.

[0045] In its initial state, the equipment is first moved to the site of the excavation pit after cleaning. The specific moving steps are as follows: Using the push handle 12, the fixed base 11 moves, causing the self-locking casters at the bottom to move. This, in turn, moves the extended plate 14 on the fixed plate 13. Once moved to the site of the excavation pit, the width of the isolation component 16 is adjusted according to the required width of the pit. After adjustment, the isolation component 16 is used to divide the pit into sections, thus enabling segmentation. Domain-separated landfilling breaks down the landfilling task into smaller units, simplifying and concentrating operations, thereby improving work efficiency and reducing construction chaos. It also makes quality inspection and control more convenient. After the foundation pit to be filled is divided into sections, the material to be filled after the well is placed is quantitatively placed into the divided foundation pit area. Finally, the moving mechanism 2 is moved downward by the set drive component 15, so that the moving mechanism 2 is located in the foundation pit to be filled, and the layer-by-layer filling of the water conservancy project foundation pit is completed.

[0046] See Figure 3 The isolation component 16 includes a sliding groove opened in the middle of the right end face of the fixed plate 13. A shaped plate 161 is fixedly connected in the sliding groove by a driving component and is slidably disposed in the sliding groove. An installation plate 162 with an opening downward "U" shape is fixedly installed at the end of the shaped plate 161 away from the fixed plate 13. A bidirectional electric push rod is fixedly installed in the middle of the left and right vertical sections of the installation plate 162. A fixed baffle 163 is fixedly installed at each of the two moving ends of the bidirectional electric push rod and is slidably disposed between the two vertical sections of the installation plate 162.

[0047] After the equipment is moved to the pit to be filled, the width of the two fixed baffles 163 is first adjusted according to the width of the pit to be filled. The specific adjustment method is as follows: the two-way electric push rod is activated to make the two fixed baffles 163 open or close synchronously between the two vertical sections of the mounting plate 162, so as to adapt to the pits with different widths to be filled, thereby improving the practicality of the equipment. After the fixed baffles 163 are adjusted, the set driving component (electric slider or electric push rod) is used to make the irregular plate 161 drive the mounting plate 162 to move downward, thereby making the mounting plate 162 drive the adjusted fixed baffles 163 to move into the pit to be filled, thereby dividing the pit into sections.

[0048] See Figure 3 and Figure 4The drive assembly 15 includes a threaded rod 151 rotatably disposed in a movable groove on a fixed plate 13 and threadedly connected to an extension plate 14. A driven bevel gear 152 is fixedly installed on the threaded rod 151 near its lower position. A circular rod is rotatably disposed on the left side of the fixed plate 13. A driving bevel gear 153 that meshes with the driven bevel gear 152 is fixedly installed at one end of the circular rod located in the movable groove. A Z-shaped rocker arm 154 is fixedly installed at the other end of the circular rod located outside the movable groove.

[0049] See Figure 2 The front end face of the fixing plate 13 is evenly provided with scale lines 131 from top to bottom near the left side.

[0050] When the foundation pit to be filled is divided into sections by the isolation component 16, and the filling material to be filled after the well is placed is placed in the divided foundation pit area, the rocker arm 154 is rotated by rotating it forward or backward. The rocker arm 154 drives the active bevel gear 153 on the circular rod to rotate, which in turn drives the driven bevel gear 152 to rotate the threaded rod 151. At this time, under the limit of the moving groove, the protruding plate 14 drives the moving mechanism 2 to move downward or upward, so that the moving mechanism 2 moves to the foundation pit area where the filling material is placed. The scale line 131 set on the front end face of the fixed plate 13 can more accurately control the position of the moving mechanism 2. The driving component 15 can control the filling material of the foundation pit to be filled layer by layer. Through continuous layer filling, the filling material can be evenly distributed and compacted, so that the filling layer has better stability, and thus can effectively control the settlement and deformation of the filling layer. At the same time, the continuous layer filling method can make the filling operation more standardized, and thus can complete the filling work more efficiently.

[0051] See Figure 2 or Figure 6 The moving mechanism 2 includes a horizontal plate 21 fixedly installed on the front end face of the protruding plate 14. A displacement groove is provided at the bottom center of the horizontal plate 21. A rectangular plate 22 is slidably connected in the displacement groove by an electric slider. A fixing block 23 is fixedly installed at the bottom of the rectangular plate 22. A rectangular groove is provided at the bottom of the fixing block 23. A spreading component 25 for evenly spreading landfill material is provided in the middle of the fixing block 23 by a moving component 24. A structural block 26 is fixedly installed at the bottom of the fixing block 23. A compaction component 27 for compacting landfill material is provided on the structural block 26.

[0052] When the threaded rod 151 is rotated, causing the protruding plate 14 to move downwards, the protruding plate 14 drives the horizontal plate 21 to move downwards. This causes the fixing block 23 on the rectangular plate 22 to move downwards. At this time, the spreading component 25 below the fixing block 23 contacts the top of the backfill material placed in the pit. The moving component 24 controls the movement of the spreading component 25. After adjustment, the electric slider is activated, causing the rectangular plate 22 to move the fixing block 23 back and forth, thereby causing the spreading component to move downwards. 25. The landfill material placed in the foundation pit is spread out back and forth to prevent it from piling up in the corners and affecting the spreading effect. The balanced load distribution can improve the bearing capacity and enhance the overall stability. During the spreading process, the landfill material is compacted by the set vibration component 27. The reciprocating vibration can generate strong vibration force and cause the landfill material to move relative to each other through vibration, which can promote the rearrangement of the landfill material and increase the density of the landfill material, thereby improving the bearing capacity and stability of the landfill area.

[0053] See Figure 6 and Figure 7 The movable component 24 includes movable channels symmetrically opened on the left and right sides of the fixed block 23 and connected to the rectangular grooves. Movable blocks 241 are slidably arranged in the movable channels. A rack plate 242 is fixedly installed at one end of the movable blocks 241 located in the rectangular groove. A rotating rod 243 is rotatably arranged in the rectangular groove of the fixed block 23. A rotating gear 244 that meshes with the left and right rack plates 242 is fixedly installed on the rotating rod 243. An electric telescopic rod that is fixedly connected to the bottom of the left movable block 241 is fixedly installed at one end of the structural block 26 located in the rectangular groove.

[0054] When the electric slider causes the rectangular plate 22 to move the fixed block 23 to the left, the right-side spreading component 25 needs to contact the top of the landfill material placed in the pit. When the rectangular plate 22 causes the fixed block 23 to move to the right, the left-side spreading component 25 needs to contact the top of the landfill material placed in the pit. The specific adjustment method is: start the electric telescopic rod to move up or down, so that the moving block 241 drives the rack plate 242 and the rotating gear 244 to mesh and transmit power, and at the same time, the moving block 241 controls the height of the left and right spreading components 25.

[0055] See Figure 6 , Figure 7 and Figure 8The spreading assembly 25 includes a vertical plate 251 fixedly installed at the end of the moving block 241 away from the fixed block 23. A first spreading plate 252 for spreading landfill material is fixedly installed at the bottom of the vertical plate 251. The side of the first spreading plate 252 near the fixed block 23 has a semi-arc structure, and multiple second spreading plates 254 are provided at both the front and rear ends of the first spreading plate 252 through multiple first disassembly assemblies 253.

[0056] See Figure 8 The first disassembly component 253 includes mounting slots at both ends of the first flat plate 252 and on the second flat plate 254 away from the first flat plate 252. A fixing plate 255 that mates with the mounting slot is fixedly installed at the end of the second flat plate 254 near the first flat plate 252. Magnets with opposite magnetic properties are fixedly installed at the end of the fixing plate 255 near the first flat plate 252 and in the mounting slot.

[0057] First, the first slab 252 and the second slab 254 are spliced ​​together according to the different widths of the foundation pit to be filled. The fixing plate 255 on the second slab 254 is installed into the mounting groove on the first slab 252 and fixed by the set magnet until the appropriate width is reached. After splicing, when the electric slider drives the fixing block 23 to move back and forth, the first slab 252 and the second slab 254 can spread the filling material placed in the foundation pit back and forth.

[0058] See section 6 for further details. Figure 7 and Figure 8 The vibration compaction assembly 27 includes a vertical plate 271 slidably disposed in the middle of the structural block 26. A first wedge block 272 is fixedly installed on the top of the vertical plate 271. The first wedge block 272 and the structural block 26 are fixedly connected by a moving spring. A second wedge block 273, which cooperates with the first wedge block 272, is fixedly installed in a rectangular groove in the fixing block 23 by an electric push rod. A first movable plate 274 is provided at the bottom of the vertical plate 271. The left and right sides of the first movable plate 274 are inverted V-shaped structures, and the top of the first movable plate 274 is open. A positioning groove is provided, and the upright plate 271 is slidably disposed in the positioning groove. A return spring fixedly connected to the upright plate 271 is provided in the positioning groove. A drive motor is also fixedly installed in the positioning groove. An eccentric wheel 275 in contact with the upright plate 271 is fixedly installed on the output shaft of the drive motor. The front and rear ends of the first moving plate 274 are provided with a second moving plate 276 through a second disassembly assembly identical to the first disassembly assembly 253. The bottom of the first moving plate 274 and the second moving plate 276 are provided with a vibrating rod 277 for vibrating the landfill material.

[0059] First, the first moving plate 274 and the second moving plate 276 are spliced ​​together according to the different widths of the foundation pit to be filled. The fixing plate 255 on the second moving plate 276 is installed into the mounting groove of the first moving plate 274 and fixed with the provided magnets until the appropriate width is reached. After splicing, during the process of leveling the filling material using the provided spreading component 25, the electric push rod is activated. The electric push rod drives the second wedge block 273 to move back and forth. At this time, under the limit of the moving spring, the second wedge block 273 drives the first wedge block 272 to move up and down, so that... The first moving plate 274 and the second moving plate 276 below the upright plate 271 drive the vibrator 277 to reciprocate and compact the landfill material. When the first moving plate 274 and the second moving plate 276 drive the vibrator 277 to vibrate up and down, the drive motor is started. At this time, under the action of the return spring, the drive motor causes the eccentric wheel 275 to press the upright plate 271, thereby causing the first moving plate 274 and the second moving plate 276 to drive the vibrator 277 to reciprocate back and forth, so that the landfill material is relatively displaced in all directions, thereby increasing the density of the landfill material.

[0060] In specific work:

[0061] Step 1: In the initial state, first move the equipment to the cleaned foundation pit that needs to be filled. At this time, adjust the width of the two fixed baffles 163 according to the width of the foundation pit to be filled. The specific adjustment method is as follows: start the bidirectional electric push rod to make the two fixed baffles 163 open or close synchronously between the two vertical sections of the mounting plate 162. After the fixed baffles 163 are adjusted, use the set driving component (electric slider or electric push rod) to make the irregular plate 161 drive the mounting plate 162 to move downward, so that the mounting plate 162 drives the adjusted fixed baffles 163 to move into the foundation pit that needs to be filled, thereby dividing the foundation pit into sections, and then quantitatively placing the filling material after the well is placed into the divided foundation pit area.

[0062] The second step involves rotating the threaded rod 151 to move the protruding plate 14 downwards, which in turn moves the horizontal plate 21 downwards. This causes the fixing block 23 on the rectangular plate 22 to move downwards. At this point, the spreading component 25 below the fixing block 23 contacts the top of the landfill material placed in the pit. The spreading component 25 is then moved by the moving component 24. After adjustment, the electric slider is activated to move the rectangular plate 22 and the fixing block 23 back and forth, thereby causing the spreading component 25 to spread the landfill material placed in the pit back and forth.

[0063] Third, the compaction component 27 can compact the landfill material. The reciprocating compaction process can generate strong vibration force, which can cause the landfill material to rearrange, thereby increasing the density of the landfill material and improving the bearing capacity and stability of the landfill area.
