Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building pile foundation construction, and in particular to a building pile foundation construction method. Background Art
[0002] A pile foundation is a deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and the pile foundation. It is referred to as a pile foundation. The main function of the pile foundation in building construction is to transfer the load of the upper building to the deep soil layer with strong bearing capacity, or to compact the soft soil layer to increase the bearing capacity and density of the foundation soil. In addition, there are two main construction forms of pile foundation, mainly cast-in-place pile foundation and prefabricated pipe pile foundation.
[0003] At present, the construction method of traditional building pile foundation usually has the following shortcomings: during the construction process, concrete is directly poured into the inside of the casting pit, ignoring the negative impact of the uneven inner wall of the casting pit on the concrete column. The inner wall of the pit is uneven, and the concrete will be subjected to uneven pressure distribution during the pouring process, resulting in local over-compaction of the concrete, which reduces the density and strength of the concrete. At the same time, it will hinder the uniform pouring of the concrete, causing the concrete to encounter protruding parts of the wall during the flow process, resulting in the concrete unable to flow smoothly to the entire area of the column, thereby affecting the filling and consistency of the concrete. During the consolidation process, the uneven wall surface will affect the shrinkage and deformation of the concrete, resulting in uneven settlement of the column and structural instability.

[0023] Compared with the prior art, the advantages of the present invention are:
[0024] 1. The present invention installs devices such as a steel cable lifter, a mounting ring and a circular scraper, and uses the circular scraper to scrape off the raised portion of the inner wall of the casting pit. The soil roller compacts the inner wall of the casting pit at the same time to avoid the raised portion causing a gap between the concrete and the inner wall of the pit, which not only affects the integrity of the structure but also causes cracks in the concrete during the curing process. The compaction of the soil roller further improves the density of the inner wall, thereby enhancing the bonding force between the concrete and the inner wall of the pit, thereby improving the stability of the concrete column.
[0025] 2. The present invention installs visual sensors, electric baffles, electric sliders and other devices, and uses visual sensors to observe whether there are convex parts on the inner wall of the casting pit. The electric slider pushes the soil scraped off by the circular scraper to the top of the electric baffle corresponding to the concave part. The soil roller fills the concave area during the rolling process, so that the inner wall of the pit is restored to flatness, thereby ensuring that the concrete is more evenly distributed in the pit during the casting process, avoiding the formation of inclined or irregular columns, or the formation of voids and loose parts, thereby improving the uniformity and quality of the structure, collecting and reusing the existing soil to fill the concave parts, reducing the use of new soil and materials, thereby saving resources and enhancing the practicality of the device.
[0026] 3. The present invention installs devices such as a vibrating rod, a mud storage ring and a reciprocating screw rod, and uses the vibrating rod to vibrate the concrete in the concrete tank. The vibration causes the concrete particles to move and rearrange, which is beneficial to improving the density and strength of the concrete and making the flow of the concrete smoother. The mud storage ring moves slowly upward from the bottom of the casting pit along the reciprocating screw rod to ensure that the concrete is evenly filled into the casting pit, avoid local accumulation or voids of the concrete, and avoid adverse effects of excessively fast flow on the quality of the concrete, which helps to maintain the slump and consistency of the concrete and allow enough time for the bubbles to escape, thereby reducing the generation of bubbles and pores in the concrete.
[0027] 4. The present invention achieves uniform pouring of concrete by arranging a plurality of mud outlets distributed in a circular array at the bottom of the mud storage ring, ensuring that the concrete is evenly distributed in the target area, which helps to reduce the pores and voids in the concrete, improve the density and quality of the concrete, and at the same time helps to achieve precise spraying of concrete, ensuring the accuracy of the concrete at the target position, and helping to improve the quality and reliability of construction.

[0045] The construction equipment used in the construction process of the above-mentioned building pile foundation construction method includes a construction platform 3 and a concrete tank 11. The casting pit 1 is set underground and excavated before construction. The construction platform 3 and the concrete tank 11 are set on the ground. A steel cage 2 is set inside the casting pit 1. The construction platform 3 is located above the casting pit 1. A motor 4 is fixedly installed on the top of the construction platform 3. A reciprocating screw 5 is fixedly connected to the output end of the motor 4. The reciprocating screw 5 passes through the construction platform 3 and is rotatably connected to the construction platform 3. The reciprocating screw 5 is located at the center of the casting pit 1. A mud storage ring 7 is threadedly connected to the reciprocating screw 5. A limit block is fixedly installed on the end of the reciprocating screw 5 away from the motor 4. The limit block is used to prevent the mud storage ring 7 from falling off the reciprocating screw 5. A fixing rod 6 is fixedly installed on the bottom of the construction platform 3. 6 passes through the mud storage ring 7 and is slidably connected with the mud storage ring 7. When the reciprocating screw 5 rotates, the mud storage ring 7 moves along the outer wall of the reciprocating screw 5 and the fixed rod 6. The bottom of the mud storage ring 7 is fixedly connected with a plurality of mud outlets 8. The plurality of mud outlets 8 are distributed in a circular array at the bottom of the mud storage ring 7. The plurality of mud outlets 8 are inclined toward the direction close to the casting pit 1. An electric control valve is arranged inside the mud outlet 8. After the electric control valve is opened, concrete is discharged from the plurality of mud outlets 8 for pouring. The concrete is sprayed at multiple points at the same time, so that the concrete is evenly poured into the target area, which helps to reduce the pores and voids in the concrete, improve the density and quality of the concrete, and at the same time, realize the uniform distribution of the density and strength of the concrete, which is beneficial to improve the bearing capacity and stability of the structure, reduce the stress concentration in the concrete, and avoid excessive load at a single point.
[0046] A vibrating rod 12 is fixedly installed on the outer wall of the concrete tank 11. The vibrating rod 12 is used to vibrate the concrete. Vibration makes the particles in the concrete more closely bonded together, reduces pores and loose parts, thereby improving the density of the concrete. At the same time, it can adjust the fluidity of the concrete, making it easier to flow in the casting pit 1 and fill small gaps. It can also cause the bubbles in the concrete to float to the surface and be released, thereby reducing the pores in the concrete.
[0047] A cement pump 14 is fixedly installed on the top of the concrete tank 11, and a mud inlet pipe 13 is fixedly connected to the side wall of the cement pump 14. The end of the mud inlet pipe 13 away from the cement pump 14 extends into the concrete tank 11, and the end of the cement pump 14 away from the mud inlet pipe 13 is fixedly connected to a mud outlet pipe 15. The end of the mud outlet pipe 15 away from the cement pump 14 extends into the casting pit 1 and is fixedly connected to the mud storage ring 7. A pipe winding seat 16 is provided between the concrete tank 11 and the casting pit 1, and a bracket 17 is fixedly installed at the bottom of the pipe winding seat 16. The middle section of the mud outlet pipe 15 is coiled on the pipe winding seat 16. The mud outlet pipe 15 is a hose, and the cement pump 14 extracts concrete in the concrete tank 11 and passes it into the mud storage ring 7.
[0048] A steel cable lifter 9 is fixedly installed on the top of the construction platform 3, and a steel cable 10 is connected to the bottom of the steel cable lifter 9. An end of the steel cable 10 away from the steel cable lifter 9 is fixedly connected to a mounting ring 18, and the mounting ring 18 is arranged between the steel cage 2 and the casting pit 1. A plurality of soil pressing rollers 24 are rotatably connected to the bottom of the mounting ring 18. The plurality of soil pressing rollers 24 are distributed in a circular array at the bottom of the mounting ring 18, and the soil pressing rollers 24 are in contact with the inner wall of the casting pit 1. A circular scraper 19 is fixedly installed on the top of the mounting ring 18. The circular scraper 19 is used to flatten the raised parts of the inner wall of the casting pit 1. The circular scraper 19 flattens the raised parts of the inner wall of the casting pit 1, and the soil pressing roller 24 rolls to further flatten and compact the inner wall of the soil, thereby improving the flatness of the inner wall of the casting pit 1, helping to ensure close contact between the concrete and the inner wall of the casting pit 1, reducing the presence of gaps and loose parts, increasing the bonding force with the concrete, helping to improve the strength and stability of the concrete column, and avoiding problems such as voids and uneven structures in the concrete.
[0049] A circular soil inlet groove 20 is provided on the top of the mounting ring 18. The soil inlet groove 20 is used to collect soil particles and other debris scraped off by the circular scraper 19. A plurality of electric sliders 22 are slidably connected inside the soil inlet groove 20. Both sides of the electric sliders 22 are inclined downward. The inclined surface can reduce the resistance of the soil, reduce the pushing force and energy consumption, and prevent the soil from getting stuck or accumulating on both sides of the electric sliders 22 during the pushing process, thereby improving the pushing speed and efficiency.
[0050] A plurality of electric-controlled baffles 21 are fixedly installed inside the soil feeding trough 20. The plurality of electric-controlled baffles 21 correspond to the plurality of soil pressing rollers 24 one by one and are located above the soil pressing rollers 24. A plurality of visual sensors 23 for observing whether a concave area appears on the inner wall of the casting soil pit 1 are fixedly installed on the top of the mounting ring 18. The plurality of visual sensors 23 are distributed in a circular array on the top of the mounting ring 18 and are located on the side of the soil feeding trough 20 away from the circular scraper 19. After the concave area is detected, the electric slider 22 pushes the soil and other particles to the corresponding electric-controlled baffle 2 1, after the electric control baffle 21 is opened, the soil falls onto the corresponding soil pressing roller 24, and the soil pressing roller 24 fills the concave part during rolling. The filling of the concave part can ensure that the concrete is more evenly distributed in the casting pit 1 during the casting process, avoiding the generation of tilted or irregular columns, and using the existing soil to fill the concave part, reducing the use of new soil and materials, thereby saving resources, achieving balanced distribution of soil, preventing the imbalance of soil quality from affecting the structure, and ensuring the stability and bearing capacity of the soil.
[0051] In the present invention, the construction of the pile foundation of the building is a very critical link, which directly affects the stability and safety of the building. When pouring concrete columns during pile foundation construction, bubbles in the concrete or a bad pouring method will lead to problems with the quality of the concrete columns; if there are pits or cracks on the inner wall of the earth pit, the concrete may flow into the cracks and pits during the pouring process, affecting the stability of the pile. The device eliminates the bubbles in the concrete, improves the pouring method, and processes the inner wall of the earth pit at the same time, ensuring that there will be no problems with the quality of the poured concrete columns.
[0052] Dig the casting pit 1 in advance, put the prefabricated steel cage 2 into the middle of the casting pit 1, start the steel cable lifter 9, and put the mounting ring 18 to the bottom along the inner wall of the casting pit 1 through the steel cable 10, start the motor 4, and the reciprocating screw rod 5 starts to rotate, moving the mud storage ring 7 fixed by the fixing rod 6 to the middle bottom of the casting pit 1.
[0053] The manufactured concrete is poured into the concrete tank 11, and the vibrating rod 12 is started to fully vibrate the concrete. The vibrating rod 12 vibrates the concrete to improve the density and fluidity of the concrete, remove bubbles, improve the quality and performance of the concrete, ensure the safety and durability of the concrete structure, and prevent the formation of honeycomb holes after pouring and shaping.
[0054] After the vibration is completed, the cement pump 14 is started, and the treated concrete is pumped into the mud outlet pipe 15 through the mud inlet pipe 13, and the concrete is filled into the mud storage ring 7 through the mud outlet pipe 15. At this time, the electric control valve in the mud outlet 8 is not opened.
[0055] After the preparation work is completed, the steel cable lifter 9 is started first, and the installation ring 18 is slowly pulled up by the steel cable 10. During the slow rise of the installation ring 18, the circular scraper 19 flattens the protruding or redundant parts of the inner wall of the casting pit 1, thereby improving the flatness of the inner wall of the casting pit 1; and the soil pressing roller 24 under the installation ring 18 rolls along the inner wall of the casting pit 1, thereby flattening and compacting the inner wall of the soil, further improving the flatness of the inner wall of the casting pit 1. Processing the inner wall can ensure close contact between the concrete and the inner wall of the pit, reduce the existence of gaps and loose parts, thereby preventing problems such as cavities and uneven structures in the concrete column, thereby improving the strength and stability of the concrete column.
[0056] However, this only solves the problem of protrusions, and does not solve the problem of small pits and depressions on the inner wall of the casting pit 1. In the process of the circular scraper 19 scraping the inner wall of the casting pit 1, excess soil will fall into the soil inlet trough 20. The visual sensor 23 surrounding the mounting ring 18 can observe whether there are small pits or depressions on the inner wall without blind spots. If small pits and depressions are observed, the electric slider 22 is started. The electric slider 22 can slide in the soil inlet trough 20, and the two sides of the electric slider 22 are beveled to push the soil in the soil inlet trough 20 to the top of the soil pressing roller 24 where the small pits and depressions appear, and the electric control baffle 21 on the soil pressing roller 24 is opened to allow the soil to fall onto the soil pressing roller 24. In the process of the soil pressing roller 24 rolling upward, the small pits and depressions are filled with the soil to ensure the flatness of the inner wall of the casting pit 1. The flat and smooth inner wall can better protect the concrete column, prevent moisture penetration and climate change from having an adverse effect on it, thereby improving the durability of the concrete column.
[0057] In this way, the soil roller 24 can flatten and compact the inner wall at normal times, and the excess soil can be used to fill the gaps and pits when filling is needed.
[0058] After the installation ring 18 rises and processes the inner wall of the casting pit 1, the electric control valve in the mud outlet 8 is opened, and concrete is ejected from multiple mud outlets 8. The motor 4 is started to rotate the reciprocating screw 5, driving the mud storage ring 7 to rise slowly. The rising speed of the mud storage ring 7 is slightly lower than the rising speed of the installation ring 18, ensuring that the mud storage ring 7 is located below the installation ring 18; generally, when pouring concrete, a large-displacement pipe is used to directly pour a large amount of concrete into the casting pit 1 quickly, which not only easily generates bubbles but also causes uneven pouring, which will reduce the quality of the concrete column. In this device, multiple mud outlets 8 evenly pour concrete, and at the same time, the rising speed of the mud storage ring 7 is slow and steady. Slowly and evenly pouring the concrete column can effectively reduce the generation of voids and bubbles in the concrete. Through slow pouring, the concrete can fully fill the voids in the casting pit 1, ensuring the density and uniformity of the concrete column.
[0059] After pouring the concrete column, wait for it to solidify and take shape, and then move the device to the next pouring pit 1 to work.
[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
