Description

Technical Field

[0001] The invention relates to the technical field of prefabricated foundation piles, and in particular to a split-type communication tower prefabricated foundation and a construction method thereof. Background Art

[0002] A prefabricated foundation is a basic structural component that is pre-made in a factory or outside a construction site according to specific designs and specifications, and then transported to the construction site for installation. Only hoisting and connection are required on site, which greatly reduces the on-site construction time and can effectively shorten the overall project period. However, compared with the traditional communication tower foundation, the prefabricated foundation is made up of multiple prefabricated components. The connection nodes are weak links, and the overall structural performance is not as good as the concrete foundation cast on site. When encountering local ground subsidence, partial ground subsidence will cause uneven force on various parts of the pile body, and the connection parts will be subjected to greater shear stress and bending moment, which can easily cause the connection to loosen, detach or even break, destroying the integrity of the pile body and reducing the bearing capacity of the pile.

[0003] Therefore, combining the advantages and disadvantages of the split communication tower prefabricated foundation and the integrated foundation, we designed a split communication tower prefabricated foundation and provided a corresponding construction method. Summary of the invention

[0006] Further to this scheme, the middle part of the second prefabricated block is recessed and the top is open. After the communication tower base block is installed on the top of the second prefabricated block, a cavity is formed in the recessed part as a pouring cavity. A pouring through hole is opened in the middle part of the communication tower base block and the pouring through hole is connected to the inside of the pouring cavity.

[0007] Further to this scheme, a circle of embedded steel bar anchor bolts is pre-embedded at the bottom of the prefabricated block 2, a reinforcement plate 2 is installed on the top of the embedded steel bar anchor bolts, and a reinforcement plate 1 is also pre-embedded inside the communication tower foundation block, and a circle of vertical steel bars is installed around the reinforcement plate 1.

[0008] Further to this solution, a hole is provided at the position of each vertical steel bar in the reinforcing plate 2 for positioning the vertical steel bar, a steel cage structure is formed between the reinforcing plate and the vertical steel bars, and the distance between the reinforcing plate 2 and the bottom wall of the pouring cavity is 0cm-30cm.

[0009] Further to this scheme, a number of through holes are provided on both sides of the prefabricated block two, as well as on the sides of the prefabricated block one and the prefabricated block three facing the prefabricated block two, and inner cavity grooves are provided inside the prefabricated block one and the prefabricated block three. The through holes provided in the prefabricated block two are connected to the inside of the pouring cavity, and the through holes provided in the prefabricated block one and the prefabricated block three are connected to the inside of the inner cavity groove. A pipe body is correspondingly provided at each through hole for connecting the prefabricated block one, the prefabricated block two and the prefabricated block three, and a reinforcement piece is also provided inside the pipe body, and the reinforcement piece is a steel structure piece.

[0010] Further to this solution, a plurality of groups of limiting bars are arranged on the inner wall of the pouring cavity, each group of limiting bars is arranged around the inner wall of the pouring cavity, and the vertical steel bars pass through the limiting bars.

[0011] Further to this solution, both sides of the prefabricated block 2 close to the prefabricated block 1 and the prefabricated block 3, as well as one side of the prefabricated block 1 and the prefabricated block 3 close to the prefabricated block 2 are provided with edge depressions, and tight-fitting parts are provided at the edge depressions, and the tight-fitting parts include steel plates, which are located at the edge depressions and have rubber sheets wrapped on their surfaces.

[0012] Further to this solution, the tops of the prefabricated block 1, prefabricated block 2, prefabricated block 3 and the communication tower base block are all provided with a plurality of lifting rings for lifting, wherein the top of the communication tower base block is provided with a recessed hole, and the lifting ring is located in the recessed hole.

[0013] A method for constructing a split communication tower, wherein the prefabricated foundation of the split communication tower comprises the following steps: Step 1: Prefabricated blocks splicing; Step 2: Install the pipe body; Step 3: Suspend the communication tower foundation block; Step 4: Pour concrete for the first time and vibrate; Step 5: Install the communication tower foundation block; Step 6: Continue pouring concrete from the pouring cavity until the concrete fills the pouring cavity. Vibrate during the pouring process. When the concrete solidifies, the construction and installation of the prefabricated foundation of the communication tower is completed.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The split communication tower prefabricated foundation and its construction method, through the setting of three prefabricated blocks and the communication tower foundation block, only need to carry out a small amount of work such as hoisting and connection, and subsequent concrete pouring on site, which reduces a lot of on-site construction time and effectively shortens the overall project period. The pouring cavity and the inner cavity groove are connected through the pipe body, which optimizes the concrete pouring process. There is no need to pour separately in multiple parts, which reduces the complexity of the pouring process, improves construction efficiency, and saves construction time and labor costs.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1 and Figure 2 As shown, the present invention provides a technical solution: a split communication tower prefabricated foundation, comprising prefabricated block one 1, prefabricated block two 2, prefabricated block three 3 and communication tower foundation block 4, prefabricated block two 2 is located between prefabricated block one 1 and prefabricated block 3, prefabricated block one 1, prefabricated block two 2 and prefabricated block three 3 are all in contact with the ground foundation at the bottom and are placed horizontally, prefabricated block one 1, prefabricated block two 2 and prefabricated block three 3 are spliced ​​and installed in the horizontal direction, and the communication tower foundation block 4 is installed on the top of prefabricated block two 2, after the construction party completes the splicing and installation of prefabricated block one 1, prefabricated block two 2, prefabricated block three 3 and communication tower foundation block 4, concrete can be poured from the communication tower foundation block 4, the concrete spreads and flows between prefabricated block one 1, prefabricated block two 2, prefabricated block three 3 and communication tower foundation block 4, and after solidification, the communication tower foundation block 4 and the three prefabricated blocks form a whole, thereby improving the strength of the prefabricated foundation of the communication tower.

[0022] like Figure 3 As shown, the middle part of the prefabricated block 2 is concave and the top is open. After the communication tower foundation block 4 is installed on the top of the prefabricated block 2, a cavity is formed at the concave part, which is a pouring cavity 201. A pouring through hole 401 is opened in the middle of the communication tower foundation block 4, and the pouring through hole 401 is connected to the inside of the pouring cavity 201. That is to say, when pouring concrete, it is necessary to pour concrete from the pouring through hole 401, and the concrete will enter the pouring cavity 201 at the first time. When the concrete in the pouring cavity 201 solidifies, it can form a whole with the communication tower foundation block 4, thereby improving the foundation strength of the communication tower installation.

[0023] Due to the reason of post-pouring, it is necessary to ensure the bonding strength between the prefabricated block 2 2 and the communication tower foundation block 4. A circle of embedded steel bar anchor bolts 14 are pre-embedded at the bottom of the prefabricated block 2 2. The top of the embedded steel bar anchor bolts 14 is used to install the reinforcing plate 2 13. A reinforcing plate 12 is also pre-embedded inside the communication tower foundation block 4. A circle of vertical steel bars 11 are installed around the reinforcing plate 12. A hole is opened at the position of each vertical steel bar 11 in the reinforcing plate 13. When the communication tower foundation block 4 is docked and installed with the prefabricated block 2 2, the vertical steel bar 11 needs to pass through the hole. That is to say, a reinforcing plate is provided at the top and bottom of the vertical steel bar 11, and a steel cage structure is formed between the reinforcing plate and the vertical steel bar 11. After the concrete pouring is completed, the steel cage structure can greatly enhance the bonding strength between the two. It should be understood that the distance between the reinforcing plate 2 13 and the bottom wall of the pouring cavity 201 is at least not less than 30 cm.

[0024] like Figure 3 As shown, the embedded steel anchor bolts 14 and the reinforcing plate 13 embedded in the bottom of the prefabricated block 2 and the vertical steel bars 11 embedded in the communication tower foundation block 4 can be accurately aligned and interlaced through the holes on the reinforcing plate during docking and installation, forming a three-dimensional steel bar connection system, which can constrain the prefabricated block 2 and the communication tower foundation block 4 from multiple directions, effectively resist various forces such as tension, compression, and shear that may occur between the two, and significantly enhance the stability of the connection. This structure can build a solid skeleton inside the concrete, so that the concrete is tightly combined with the steel bars after solidification. The steel cage structure composed of the reinforcing plate and the steel bars makes the prefabricated block 2 and the communication tower foundation block 4 an integral force-bearing structure after the concrete is poured. When the structure is subjected to external force, the force can be effectively transmitted and distributed between the prefabricated block 2 and the communication tower foundation block 4 through the steel cage, avoiding the situation of excessive local force, making the entire structure work in coordination, and improving the integrity and stability of the structure.

[0025] like Figure 3As shown, further, a plurality of through holes are provided on both sides of the prefabricated block 2, and on the side of the prefabricated block 1 and the prefabricated block 3 facing the prefabricated block 2. The prefabricated block 1 and the prefabricated block 3 are provided with inner cavity grooves 8. The through holes provided in the prefabricated block 2 are connected to the inside of the pouring cavity 201, and the through holes provided in the prefabricated block 1 and the prefabricated block 3 are connected to the inside of the inner cavity groove 8. A tube body 10 is provided at each through hole, and the tube body 10 can be a plastic tube, an alloy tube or a steel tube, etc. A tubular structure that is adapted to the inner wall of the through hole and is passed through at both ends, that is, the tube body 10 can be used to connect the pouring cavity 201 and the inner cavity groove 8. When pouring concrete, the concrete overflows from the tube body 10 and enters the inner cavity groove 8. The tube body 10 can also effectively prevent the concrete from overflowing from the joint between the two prefabricated blocks. A reinforcement member 9 is also arranged in the tube body 10. The reinforcement member 9 can be a steel structure such as a steel bar or a small steel cage that can increase the strength of the concrete after solidification.

[0026] like Figure 3 As shown, the pouring cavity 201 is connected with the inner cavity groove 8 through the pipe body 10, so that when pouring concrete, the concrete can overflow from the pipe body 10 into the inner cavity groove 8, ensuring that each prefabricated block connection part can be filled with concrete, ensuring the integrity of the overall structure casting, effectively avoiding the occurrence of casting dead corners or cavities, and enhancing the overall strength and stability of the split foundation piles after splicing. This connection design optimizes the concrete pouring process, and there is no need to perform pouring operations at multiple locations separately, which reduces the complexity of the pouring process, improves construction efficiency, saves construction time and labor costs. During the concrete solidification process, the reinforcement 9 and the concrete bite each other, which improves the tensile and shear resistance of the concrete, enhances the mechanical properties of the pipe body and the entire prefabricated block connection part, and further improves the bearing capacity and stability of the split foundation piles during use, reduces the possibility of damage or deformation of the foundation piles due to external forces, and extends the service life of the foundation piles.

[0027] like Figure 3 As shown, a plurality of groups of limiting ribs 15 are arranged on the inner wall of the pouring cavity 201, and each group of limiting ribs 15 is arranged around the inner wall of the pouring cavity 201. The vertical steel bars 11 can pass through the limiting ribs 15, further increasing the structural stability of the vertical steel bars 11 and the hoisting stability of the communication tower foundation block 4.

[0028] Replay Figure 1, on both sides of the prefabricated block 2 2 close to the prefabricated block 1 1 and the prefabricated block 3 3, and on one side of the prefabricated block 1 1 and the prefabricated block 3 3 close to the prefabricated block 2 2, transverse steel bars 6 are embedded, and threads formed by tapping are arranged at both ends of the transverse steel bars 6. Splicing plates 5 are arranged at the joints on both sides of the prefabricated block 1 1, the prefabricated block 2 2 and the prefabricated block 3 3, and holes corresponding to each transverse steel bar 6 are opened on the splicing plates 5. The splicing plates 5 are passed through the transverse steel bars 6 and attached to the surface of the prefabricated block, and the splicing plates 5 are fixed with nuts. Before pouring, the prefabricated block 1, the prefabricated block 2 and the prefabricated block 3 are connected using the splicing plate 5, which can effectively enhance the connection strength of the split foundation piles at the splicing points, so that the foundation piles can work better together when subjected to external forces, thereby improving the overall bearing capacity. This connection method can limit the relative displacement between the prefabricated blocks, and when the foundation piles are subjected to horizontal forces, vertical forces or other external forces, reduce the possibility of dislocation, separation, etc. between the prefabricated blocks, thereby improving the stability and seismic resistance of the entire foundation pile structure.

[0029] like Figure 4 As shown, edge recesses 18 are provided on both sides of prefabricated block 2 2 close to prefabricated block 1 1 and prefabricated block 3 3, as well as on one side of prefabricated block 1 1 and prefabricated block 3 3 close to prefabricated block 2 2. A tight-fitting part is provided at the edge recess 18. The tight-fitting part includes a steel plate 16. The steel plate 16 is located at the edge recess 18 and the surface is wrapped with a rubber sheet 17. That is to say, when the joints of prefabricated block 1 1, prefabricated block 2 2, prefabricated block 3 3 and communication tower foundation block 4 are connected, they are in contact with each other by the rubber sheet 17. Since the molecular chain of rubber has greater flexibility and interaction ability, when two rubber blocks are squeezed together, the rubber molecular chain segments will approach each other. That is to say, due to the close fit of the rubber sheet 17 at the joint, the sealing of the joint can be ensured, and the intrusion of rainwater from the joint to erode the concrete is reduced.

[0030] Based on the above communication tower prefabricated foundation, we propose a construction method that relies on the above communication tower prefabricated foundation: Step 1: Splicing of prefabricated blocks. Pass the splicing plate 5 through the transverse steel bars 6 embedded in the corresponding positions of prefabricated block 1, prefabricated block 2 and prefabricated block 3, so that it fits tightly against the surface of the prefabricated blocks. Then use the matching nuts to fix them. When tightening the nuts, use a torque wrench to operate according to the specified torque value to ensure that the splicing is firm and that the prefabricated blocks after splicing are accurately positioned in the horizontal direction, and the bottom is in full contact with the ground foundation and remains horizontal.

[0031] Step 2: Install the tube body 10; insert the matching tube body 10 into the through holes of each prefabricated block, ensuring that the tube body 10 fits tightly against the inner wall of the through hole and both ends are connected.

[0032] Step 3: Suspend the communication tower foundation block 4; use the lifting equipment to suspend the communication tower foundation block 4, slowly lift it to a position 1-2 meters above the prefabricated block 2, and insert the vertical steel bars 11 into at least the first group of limiting bars 15. During the suspension process, keep the communication tower foundation block 4 horizontal, and arrange special personnel to observe its surrounding environment to ensure safety.

[0033] Step 4: Pour concrete and vibrate for the first time. Pour concrete into the pouring cavity 201 and vibrate until the concrete overflows into the inner cavity groove 8. Stop pouring concrete when the concrete is poured to a distance of 10 cm to 20 cm from the top of the prefabricated block 2.

[0034] Step 5: Install the communication tower foundation block 4 and use the lifting equipment to place the communication tower foundation block 4 on top of the prefabricated block 2 2 .

[0035] Step 6: Continue pouring concrete from the pouring cavity 201 until the concrete fills the pouring cavity 201 , vibrate during the pouring process, and complete the construction and installation of the prefabricated foundation of the communication tower after the concrete solidifies.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
