Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to a conversion installation method and equipment for vertical pump pipes in a core tube construction super high-rise building. Background Art

[0002] Currently, the integral steel platform formwork system is commonly used for the construction of super-high-rise core tubes. This system is gaining popularity due to its advantages, including fast construction speed, good sealing performance, high degree of mechanization, and ability to provide a work surface for large-scale construction equipment such as tower cranes and concrete placing booms. In the super-high-rise core tube construction process, the core tube walls and connecting beams are constructed first, with the core tube walls leading the outer frame structure by 4 to 8 floors. The outer frame structure is then completed, and the outer frame and the horizontal floor slabs within the core tube are constructed 1 to 2 floors below the outer frame structure. During the construction of the core tube wall, concrete is usually transported to a higher pouring position by pumping. Therefore, a vertical pump pipe needs to be installed in the vertical direction. However, as the height increases, the potential energy of the concrete increases, and the reaction force during the pumping of the concrete through a single pump pipe and the impact force when the pump pipe is cleaned and falls back increase accordingly. In this field, the horizontal pump pipe is generally reinforced and fixed with concrete blocks at the junction of the horizontal base pump pipe and the vertical pump pipe to resist the fall-back impact load of concrete or water. However, with the emergence of super-high-rise buildings over 500 meters, the fall-back impact load generated during concrete pumping or water cleaning is getting larger and larger. Therefore, the method of reinforcing the horizontal pump pipe at the junction of the horizontal base pump pipe and the vertical pump pipe is difficult to solve the fall-back impact load of a single vertical pump pipe. Therefore, how to resist, consume, and buffer the fall-back load of concrete or water in a single vertical pump pipe has become a technical problem that urgently needs to be solved in this field to prevent the fall-back impact load of the reaction force of the single vertical pump pipe when pumping concrete or water from causing irreversible damage to the concrete pump machine. Summary of the Invention

[0003] The purpose of the present invention is to provide a method and equipment for converting and installing vertical pump pipes in super high-rise buildings with core tube construction, so as to solve the technical problem of how to resist, consume and buffer the fallback load of concrete or water in a single vertical pump pipe.

[0004] In order to solve the above technical problems, the present invention provides a technical solution: a method for converting and installing vertical pump pipes in a core tube construction super high-rise building, comprising the following steps:

[0005] Step 1: Casting of the core tube wall of the super high-rise building is carried out. The integral steel platform formwork is raised as the core tube wall rises. An Nth vertical pump pipe attached to the integral steel platform formwork is extended and installed on the core tube wall as a vertical pump pipe. The concrete placing boom located on the integral steel platform formwork uses the extended Nth vertical pump pipe as a vertical pump pipe to transport concrete to cast and raise the core tube wall, as well as the outer frame structure and floor slabs that lag behind the core tube wall in construction.

[0006] Step 2: Below the safety height of the Nth vertical pump pipe, when the integral steel platform formwork is lifted to the vertical pump pipe conversion position as the core tube wall is elevated, the Nth vertical pump pipe attached thereto is extended and installed on the core tube wall through the integral steel platform formwork, and at the same time, the N+1th vertical pump pipe attached thereto is installed at other vertical positions on the core tube wall. The concrete placing boom continues to use the Nth vertical pump pipe as a vertical pumping pipe to transport concrete to cast and increase the core tube wall, as well as the outer frame structure and floor slab whose construction lags behind the core tube wall. When the integral steel platform formwork is lifted as the core tube wall is elevated, the Nth vertical pump pipe and the N+1th vertical pump pipe are synchronously extended and installed on the integral steel platform formwork, where N is an integer greater than 0.

[0007] Step three, when the floor construction reaches the floor where the vertical pump pipe conversion position is located, a fixed block is set on the floor of the floor, and the Nth vertical pump pipe is connected to the N+1th vertical pump pipe through the first bend pump pipe, the horizontal conversion pump pipe and the second bend pump pipe to complete the conversion and installation of the vertical pump pipe, and the horizontal conversion pump pipe is fixed on the fixed block. The concrete placing machine switches to the N+1th vertical pump pipe as a vertical pumping pipe to transport concrete to cast the core tube wall and increase the height of the construction, as well as the outer frame structure and floor slab that lag behind the core tube wall. When the overall steel platform formwork is lifted as the core tube wall is raised, the N+1th vertical pump pipe is extended and installed on the overall steel platform formwork.

[0008] Furthermore, the present invention provides a method for converting and installing vertical pump pipes in a super-high-rise building constructed with a core tube, wherein the N+1th vertical pump pipe and the Nth vertical pump pipe after conversion and installation are on the same wall surface or different wall surfaces of the core tube wall.

[0009] Furthermore, the present invention provides a method for converting and installing vertical pump pipes in a super-high-rise building with a core tube construction. When the core tube wall is not tapered or missing, the vertical pump pipe conversion position is determined based on the safety height of the Nth vertical pump pipe to carry out conversion and installation of the N+1th vertical pump pipe and the Nth vertical pump pipe; when the core tube wall is tapered or missing, the vertical pump pipe conversion position is determined without considering the safety height of the Nth vertical pump pipe to carry out conversion and installation of the N+1th vertical pump pipe and the Nth vertical pump pipe.

[0010] Furthermore, the present invention provides a method for converting and installing vertical pump pipes in a core tube construction super high-rise building, wherein the safe height of the Nth vertical pump pipe is below 300 meters.

[0011] Furthermore, the present invention provides a method for converting and installing vertical pump pipes in a super-high-rise building constructed in a core tube, wherein the position of the N+1 vertical pump pipe to be installed is determined by a conversion and installation device of the vertical pump pipe according to the installed N vertical pump pipe for installation. The conversion and installation device includes a ranging transmitting device arranged on a pump pipe fixing device above the N vertical pump pipe to be extended and installed on the core tube wall, and a ranging receiving device arranged on a pump pipe adjustment fixing device at another vertical position of the core tube wall. The ranging transmitting device is provided with a laser rangefinder, which adjusts the position of the pump pipe adjustment fixing device and the ranging receiving device thereon relative to the core tube wall. When the distance measured by the laser rangefinder aligned with the ranging receiving device is equal to the total length of the first curved pump pipe, the horizontal conversion pump pipe and the second curved pump pipe, the conversion position of the pump pipe adjustment fixing device relative to the core tube wall is determined to determine the installation position of the N+1 vertical pump pipe.

[0012] Install the pump pipe fixture attached to the core tube wall above the pump pipe fixture on which the distance measuring and transmitting device is installed through the integral steel platform formwork, pull out the distance measuring and transmitting device from the pump pipe fixture, and extend and install the standard section of the Nth vertical pump pipe through two or more pump pipe fixtures;

[0013] The pump pipe fixture attached to the core tube wall is installed above the pump pipe adjustment fixture installed with the distance measuring receiving device through the integral steel platform formwork according to the determined installation position of the N+1 vertical pump pipe, the distance measuring receiving device is pulled out from the pump pipe adjustment fixture, the starting standard section of the N+1 vertical pump pipe is installed through the pump pipe adjustment fixture and the pump pipe fixture above it, and the subsequent standard sections of the N+1 vertical pump pipe are extended and installed through the pump pipe fixture attached to the core tube wall.

[0014] Furthermore, the present invention provides a conversion and installation method for vertical pump pipes in a core tube construction super high-rise building, wherein the pump pipe fixing device includes an embedded part arranged on the core tube wall, and a pump pipe fixing part arranged on the embedded part perpendicular to the core tube wall.

[0015] Furthermore, the present invention provides a method for converting and installing vertical pump pipes in a core tube construction super high-rise building, wherein the pump pipe adjustment and fixing device includes an embedded part arranged on the core tube wall, a track plate arranged on the embedded part perpendicular to the core tube wall, and a pump pipe fixing part adjustably arranged on the track plate perpendicular to the core tube wall.

[0016] Compared with the prior art, the present invention provides a method for converting and installing vertical pump pipes in super-high-rise buildings during the core tube construction. Below the safety height of each vertical pump pipe, the Nth vertical pump pipe in use is extended and installed at the conversion position through the integral steel platform formwork, and the N+1th vertical pump pipe is newly installed on the core tube wall. Then, when the floor slab is constructed to the floor where the conversion position is located, the Nth vertical pump pipe and the N+1th vertical pump pipe are connected through the horizontal conversion pump pipe and the first elbow pump pipe and the second elbow pump pipe, thereby reducing the construction difficulty and convenience of extending the installation of the vertical pump pipe in use and the installation of another vertical pump pipe. The construction efficiency is improved, and the problem of difficulty in converting and installing the vertical pump pipes is avoided, such as the need to remove the wall bracket when constructing the core tube wall first and the outer frame structure and floor slab later in the absence of a floor slab below the core tube wall, and the need to repeatedly disassemble and install the wall bracket when the Nth vertical pump pipe and the N+1st vertical pump pipe are connected to the Nth vertical pump pipe through the horizontal conversion pump pipe and the elbow pump pipe, and the N+1st vertical pump pipe is fixed at another vertical position of the core tube wall. The problem of difficulty in construction is also avoided, such as the need to remove the wall bracket when the floor slab is constructed to the conversion position, and the need to repeatedly disassemble and install the wall bracket when converting and installing the vertical pump pipe.

[0017] The embodiment of the present invention provides a method for converting and installing vertical pump pipes in a super-high-rise building during core tube construction, which switches to the N+1th vertical pump pipe for subsequent pouring construction. The method has the advantages of: pouring construction of the super-high-rise building by switching the converted and installed vertical pump pipes, reducing the potential energy difference of each vertical pump pipe and the potential energy difference of the vertical pump pipes at the total elevation through the safe height of each vertical pump pipe and the horizontal conversion pump pipe at the conversion position, reducing the potential energy difference generated by a single vertical pump pipe when pumping concrete or water cleaning and falling back, effectively resisting, consuming and buffering the damage to the pump pipe and the pump machine caused by the impact force of the falling load during the pumping of concrete or water cleaning, and the conversion installation of the vertical pump pipes is carried out under the premise of the safe height of each vertical pump pipe, thereby improving the safety of each vertical pump pipe in the pouring construction of the super-high-rise building before and after switching.

[0018] In order to achieve accurate positioning and installation of the N+1th vertical pump pipe, the present invention also provides a conversion and installation device for vertical pump pipes in a core tube construction super high-rise building, comprising:

[0019] The ranging transmitter comprises a first centering plug, an adjustment platform provided on the upper surface of the first centering plug, and a laser rangefinder provided on the adjustment platform; the ranging transmitter is pluggably provided on the core tube wall above the Nth vertical pump pipe to be extended and installed via the centering plug;

[0020] The distance measuring receiving device includes a second centering plug and a positioning body rotatably arranged on the second centering plug. The positioning body is an open-angle cylinder with an angle opened along the axial center of the cylinder. The axial center line of the positioning body is the positioning line. The laser rangefinder is aligned with the positioning line by rotating the positioning body. The distance measuring receiving device is pluggable and arranged on a pump pipe adjustment fixing device at another vertical position of the core tube wall.

[0021] Furthermore, the present invention provides a conversion and installation device for vertical pump pipes in core tube construction of super high-rise buildings.

[0022] The first and second centering plugs each include a guide cone, a cylindrical plug body and a chuck that are centrally aligned from bottom to top. The maximum dimension of the chuck cross section is larger than the diameter of the cylindrical plug body, and the diameter of the cylindrical plug body is the same as the diameter of the vertical pump tube.

[0023] Furthermore, the present invention provides a conversion and installation device for vertical pump pipes in a core tube construction super high-rise building, wherein the adjustment platform includes a horizontal plate, a leveling rod and a level meter arranged on the horizontal plate.

[0024] Compared with the prior art, the present invention provides a conversion and installation device for vertical pump pipes in super-high-rise buildings constructed in the core tube. It can determine the position of the N+1 vertical pump pipe to be installed based on the installed N vertical pump pipe, adjust the position of the pump pipe adjustment fixture and the distance measuring receiving device thereon relative to the core tube wall, and determine the conversion position of the pump pipe adjustment fixture relative to the core tube wall when the distance measured by the laser rangefinder aligned with the distance measuring receiving device is equal to the total length of the first bend pump pipe, the horizontal conversion pump pipe, and the second bend pump pipe. The installation position of the N+1 vertical pump pipe is determined. In addition, it ensures that the horizontal conversion pump pipe is assembled with one or more uncut pump pipe standard sections and assembled with the first bend pump pipe and the second bend pump pipe, thereby improving the reliable connection of the horizontal conversion pump pipe and the pump pipes connected thereto. It overcomes the construction difficulty that the integral steel platform formwork is attached to the core tube wall, which presents measurement obstacles and makes it impossible to directly accurately locate the N+1 vertical pump pipe using a tape measure or a laser rangefinder.

[0054] The present invention will be described in detail below with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are all in a very simplified form and are not accurately scaled, and are only used to facilitate and clearly illustrate the embodiments of the present invention.

[0055] Please refer to Figures 1 to 6 The embodiment of the present invention provides a method for converting and installing vertical pump pipes in a core tube construction super high-rise building, which may include the following steps:

[0056] Step 1, please refer to Figure 1 , the core tube wall 410 of the super high-rise building 400 is cast, the integral steel platform formwork 500 is lifted as the core tube wall 410 rises, and the Nth vertical pump pipe 230 attached thereto is extended and installed on the core tube wall 410 through the integral steel platform formwork 500 as a vertical pumping pipe. The concrete placing boom 600 located on the integral steel platform formwork 500 transports concrete through the extended Nth vertical pump pipe 230 as a vertical pumping pipe to cast and raise the core tube wall 410 and follow the construction of the outer frame structure 420 and the floor slab 430 that lag behind the core tube wall 410.

[0057] For step 2, please refer to Figure 2A 、 Figure 2B 、 Figure 3A 、 Figure 3B and Figure 4A , below the safety height of the Nth vertical pump pipe 230, when the integral steel platform formwork 500 is lifted to the vertical pump pipe conversion position as the core tube wall 410 is raised, the Nth vertical pump pipe 230 attached thereto is extended and installed on the core tube wall 410 through the integral steel platform formwork 500, and at the same time, the N+1th vertical pump pipe 240 attached thereto is installed at other vertical positions on the core tube wall 410, and the concrete placing boom 600 continues to use the Nth vertical pump pipe 230 as a vertical pumping pipe to transport concrete to cast and raise the core tube wall 410, as well as the outer frame structure 420 and floor slab 430 that lag behind the core tube wall 410 in construction. When the integral steel platform formwork 500 is lifted as the core tube wall 410 is raised, the Nth vertical pump pipe 230 and the N+1th vertical pump pipe 240 are synchronously extended and installed on the integral steel platform formwork 500, where N is an integer greater than 0. In step 2, because the (N+1)th vertical pump pipe 240 is disconnected from the (N)th vertical pump pipe 230, the concrete placing boom 600 must continue to use the (N)th vertical pump pipe 230 as the vertical pumping pipe to pour and raise the core wall 410. The safe height of the vertical pump pipes before and after the conversion is 300 meters or less. This means that the safe height of the (N)th vertical pump pipe 230 is 300 meters or less. Each vertical pump pipe is installed at a specific height to improve construction safety.

[0058] Step 3, please refer to Figure 4A 、 Figure 4B 、 Figure 5A 、 Figure 5BAfter the floor slab 430 is constructed to the floor where the vertical pump pipe conversion position is located, a fixed block 300 is provided on the floor slab 430 of the floor, and the Nth vertical pump pipe 230 is connected to the N+1th vertical pump pipe 240 through the first curved pump pipe 251, the horizontal conversion pump pipe 250 and the second curved pump pipe 252, completing the conversion and installation of the vertical pump pipe. The horizontal conversion pump pipe 250 is fixed on the fixed block 300, and the concrete placing boom 600 switches to the N+1th vertical pump pipe 240 as a vertical pumping pipe to transport concrete to cast and increase the height of the core tube wall 410 and to follow the construction of the outer frame structure 420 and the floor slab 430 that lag behind the core tube wall 410. When the integral steel platform formwork 500 is lifted as the core tube wall 410 is raised, the N+1th vertical pump pipe 240 is extended and installed on the integral steel platform formwork 500. At the connection point between the first curved pump pipe 251 and the Nth vertical pump pipe 230, the Nth vertical pump pipe 230 above the installation point needs to be removed or lifted upward to connect the first curved pump pipe 251 with the Nth vertical pump pipe 230. The concrete placing boom 600 and the vertical pump pipe can be connected via a hose.

[0059] Please refer to Figures 1 to 6 The embodiment of the present invention provides a method for converting and installing vertical pump pipes in a super-high-rise building during core tube construction. Below the safety height H of each vertical pump pipe, the Nth vertical pump pipe 230 in use is extended and installed at the conversion position through the integral steel platform formwork 500, and the N+1th vertical pump pipe 240 is newly installed on the core tube wall. Then, when the floor slab 430 is constructed to the floor where the conversion position is located, the Nth vertical pump pipe 230 and the N+1th vertical pump pipe 240 are connected through the horizontal conversion pump pipe 250 and the first bend pump pipe 251 and the second bend pump pipe 252, thereby reducing the construction difficulty of extending the Nth vertical pump pipe in use and newly installing the N+1th vertical pump pipe 240 and improving the construction efficiency. The construction efficiency is improved, and it is avoided that when the core tube wall 410 of a super high-rise building is constructed first and the outer frame structure 420 and the floor slab 30 are constructed later, when there is no floor slab 430 below the core tube wall 410, a wall-mounted bracket is installed on the core tube wall 430 to directly connect the Nth vertical pump pipe 230 through the horizontal conversion pump pipe 250 and two bend pump pipes to the N+1th vertical pump pipe 240, and the N+1th vertical pump pipe 240 is fixedly set at another vertical position of the core tube wall 410, which makes the vertical pump pipe conversion installation difficult. It also avoids the problem that when the floor slab 430 is constructed to the conversion position, the wall-mounted bracket needs to be removed, resulting in the conversion installation of the vertical pump pipe requiring repeated disassembly and assembly of the wall-mounted bracket, which causes construction difficulties.

[0060] Please refer to Figures 1 to 6The embodiment of the present invention provides a method for converting and installing vertical pump pipes in a super-high-rise building during core tube construction, which switches to the N+1 vertical pump pipe 240 for subsequent pouring construction. The advantage is that the super-high-rise building is poured by switching the N+1 vertical pump pipe 240 after conversion and installation, and the potential energy difference of each vertical pump pipe and the potential energy difference of the vertical pump pipes at the total elevation are reduced by the safe height of each vertical pump pipe and the horizontal conversion pump pipe 250 at the conversion position, thereby reducing the potential energy difference generated by a single vertical pump pipe when pumping concrete or water cleaning and falling back, effectively resisting, consuming, and buffering the damage to the pump pipe and the pump machine 210 caused by the impact force of the falling load during the pumping of concrete or water cleaning, and the conversion installation of the vertical pump pipe is carried out under the premise of the safe height of each vertical pump pipe, thereby improving the safety of each vertical pump pipe in the pouring construction of the super-high-rise building before and after switching.

[0061] Please refer to Figures 1 to 6 In the embodiment of the present invention, a method for converting and installing vertical pump pipes in a core tube construction super high-rise building is provided. The horizontal conversion pump pipe 250 can be fixed on the fixing block 300 by a pump pipe fixing device 700, thereby improving the reliability, stability and safety of the horizontal conversion pump pipe 250 when pumping concrete or water, and resisting, consuming and buffering the load impact force of the pumped concrete falling back or the water washing falling back.

[0062] Please refer to Figure 4A 、 Figure 4B 、 Figure 5A 、 Figure 5B , the embodiment of the present invention provides a method for converting and installing vertical pump pipes in a core tube construction super high-rise building. After following steps one to three above, the pumping system 200 now includes a pump 210 arranged on the ground, a horizontal base pump pipe 220 horizontally connected to the pump 210, the first to N+1 vertical pump pipes connected to the horizontal base pump pipe 220, and a horizontal conversion pump pipe 250 and a first bend pump pipe 251 and a second bend pump pipe 252 between two adjacent vertical pump pipes. When N=1, the Nth vertical pump pipe 230 and the N+1th vertical pump pipe 240 at this time correspond to the first vertical pump pipe and the second vertical pump pipe, respectively.

[0063] Please refer to Figure 6 The embodiment of the present invention provides a method for converting and installing vertical pump pipes in a super high-rise building constructed with a core tube. Steps 2 to 3 are repeatedly performed to convert and install the vertical pump pipes in the super high-rise building constructed with a core tube multiple times, thereby completing the construction of the core tube wall 410 of the super high-rise building 400 and the construction of the outer frame structure 420 and the floor slab 430 behind the core tube wall 410. Figure 6The example in the figure illustrates a super high-rise building 400 constructed by converting and installing four vertical pump pipes three times. When the Nth vertical pump pipe 230 is the starting vertical pump pipe of the super high-rise building 400 on the ground, that is, when N=1, the Nth vertical pump pipe 230, the N+1th vertical pump pipe 240, the N+2th vertical pump pipe 260, and the N+3th vertical pump pipe 270 correspond to the first through fourth vertical pump pipes, respectively. Adjacent vertical pump pipes are both converted and connected via the horizontal conversion pump pipe 250, the first elbow pump pipe 251, and the second elbow pump pipe 252. The difference is that, depending on the conversion installation position of the next vertical pump pipe 230, the angle or direction of the first elbow pump pipe 251 and the second elbow pump pipe 252 need to be adjusted to achieve the purpose of connection. The scheme of multiple conversion installations of vertical pump pipes and use of the converted vertical pump pipes for subsequent pouring construction can achieve the purpose of resisting, consuming and buffering the load impact force of the pumped concrete or the water washing return. It is suitable for super high-rise buildings, especially super high-rise buildings over 500 meters.

[0064] Please refer to Figures 1 to 6 To further resist, consume, and buffer the impact force of the pumped concrete falling back or the load caused by water washing, the horizontal base pump pipe 220 in the pumping system 200 is fixed to the fixed block 300 via the pump pipe fixing device 700. The fixed block 300 can be a plurality of concrete piers dispersed below the horizontal base pump pipe 230. The multiple fixed blocks 300 can resist, consume, and buffer the impact force of the load. Of course, to further achieve the purpose of resisting, consuming, and buffering the impact force of the concrete falling back or the load caused by water washing, the first vertical pump pipe on the floor 430 close to the ground 100 can also be connected to the buffer valve 231. The fixed block 300 solution is suitable for low-rise buildings and super high-rise buildings under 300 meters.

[0065] Please refer to Figure 13 The embodiment of the present invention provides a method for converting and installing vertical pump pipes in a core tube construction super high-rise building. After conversion and installation, the N+1 vertical pump pipe 240 and the N vertical pump pipe 230 are on the same wall surface or different wall surfaces of the core tube wall 410. Figure 13 The lower left side of the middle shows the situation where two vertical pump pipes are located on the same wall after the conversion installation. Figure 13 The lower right side of the middle shows the situation where the two vertical pump pipes are located on different walls after the conversion installation. Figure 6 , multiple conversions of two vertical pump pipes located on different walls can continue to be converted at the same vertical position. In this case, the position of the placing boom 600 on the integral steel platform formwork 500 remains unchanged or moves a small distance, which improves construction safety, reduces unnecessary construction processes, and indirectly improves construction efficiency. Of course, according to actual construction conditions, each conversion can be located on non-overlapping vertical walls.

[0066] The embodiment of the present invention provides a method for converting and installing vertical pump pipes in a super high-rise building constructed with a core tube. When the core tube wall 410 is not shrinking or missing, the vertical pump pipe conversion position is determined based on the safety height of the Nth vertical pump pipe 230 in the above steps to convert and install the N+1th vertical pump pipe 240 and the Nth vertical pump pipe 230; when the core tube wall 410 is shrinking or missing, the vertical pump pipe conversion position is determined without considering the safety height of the Nth vertical pump pipe 230 to convert and install the N+1th vertical pump pipe 240 and the Nth vertical pump pipe 230. Please refer to Figures 13 and 14 This illustrates the situation where, in a super-high-rise building, the core tube wall 410 is tapered or missing, and the (N+1)th vertical pump pipe 240, after being reinstalled, is located on the tapered or intact core tube wall 410. Where the core tube wall 410 is missing or tapered, the corresponding components of the integral steel platform formwork in the missing core tube wall 420 must be removed to complete the deformation of the integral steel platform formwork.

[0067] Please refer to Figure 7A 、 Figures 7B to 7F 、 Figure 2A 、 Figure 2B 、 Figure 3A 、 Figure 3B 、 Figure 4A 、 Figure 4BThe embodiment of the present invention provides a method for converting and installing vertical pump pipes in a core tube construction super high-rise building. The method determines the position of the N+1 vertical pump pipe 240 to be installed according to the installed N vertical pump pipe 230 through a vertical pump pipe conversion and installation device. The conversion and installation device includes a ranging transmitter 910 set on a pump pipe fixing device 700 above the N vertical pump pipe 230 to be extended and installed on the core tube wall 410, and a pump pipe adjustment fixing device 910 set at another vertical position of the core tube wall 410. The distance measuring receiving device 920 on the fixing device 800 is provided with a laser rangefinder 913 on the distance measuring transmitting device 910. The pump pipe adjusting fixing device 800 and the distance measuring receiving device 920 thereon are adjusted relative to the core tube wall 410. When the distance measured by the laser rangefinder 913 aligned with the distance measuring receiving device 920 is equal to the total length of the first curved pump pipe 251, the horizontal conversion pump pipe 250 and the second curved pump pipe 252, the conversion of the pump pipe adjusting fixing device 800 relative to the core tube wall 410 is determined. The installation position of the N+1 vertical pump pipe 240 is determined by the position; the pump pipe fixture 700 attached to the core tube wall 410 is installed above the pump pipe fixture 700 installed with the distance measuring transmitter 910 through the integral steel platform formwork 500, the distance measuring transmitter 910 is pulled out from the lower pump pipe fixture 700, and the standard section of the N vertical pump pipe 230 is installed by extending two or more pump pipe fixtures 700; the pump pipe 230 installed with the distance measuring receiver 920 is installed through the integral steel platform formwork 500. The pump pipe fixture 700 attached to the core tube wall 410 is installed above the adjusting fixture 800 according to the determined installation position of the N+1th vertical pump pipe 240, the distance measuring receiving device 920 is pulled out on the pump pipe adjusting fixture 800, the starting standard section of the N+1th vertical pump pipe 240 is installed through the pump pipe adjusting fixture 800 and the pump pipe fixture 700 thereon, and the subsequent standard sections of the N+1th vertical pump pipe are extended and installed through the pump pipe fixture 700 attached to the core tube wall 410.

[0068] The pump pipe fixture 700, pump pipe adjustment fixture 800, and their corresponding distance measuring transmitter 910, distance measuring receiver 920, and vertical pump pipes are all installed via the integral steel platform formwork 500, reducing construction difficulty and improving efficiency. Besides the installation of the initial standard section of the (N+1)th vertical pump pipe 240, the extensions of the (N+1)th vertical pump pipe 240 and the (N)th vertical pump pipe 230 are all attached to the core tube wall 410 via the pump pipe fixture 700.

[0069] The above-mentioned solution of determining the position of the (N+1)th vertical pump pipe 240 to be installed based on the installed (N)th vertical pump pipe 230 by using the vertical pump pipe conversion installation device can determine the total length of the first bend pump pipe 251, the horizontal conversion pump pipe 250, and the second bend pump pipe 252 based on the vertical pump pipe conversion installation device, so as to determine the exact position of the pump pipe adjustment fixture 800 relative to the core tube wall 410 based on the total length by adjusting the distance measuring receiving device 920 on the pump pipe adjustment fixture 800. The purpose of this solution is that since both horizontal and vertical pump pipes are extended and installed using pump pipe standard sections, the pump pipe standard sections have a fixed length, and since both ends of the pump pipe standard sections have flanges, it is impossible to cut the pump pipe standard sections to assemble the horizontal conversion pump pipe 250. Therefore, the above-mentioned method is required to accurately locate the position of the starting standard section of the (N+1)th vertical pump pipe 240 without cutting the pump pipe standard sections. Furthermore, the standard section of pump pipe cannot be cut or connected due to its inherent corrosion and rust-proofing protective layer. Furthermore, due to the attachment of the integral steel platform formwork 500 to the core tube wall 410, there is a measurement barrier between the two vertical pump pipes. Therefore, conventional tape measures and single laser rangefinders cannot directly determine the exact position of the (N+1)th vertical pump pipe 240 on the integral steel platform formwork 500. However, the method of determining the position of the (N+1)th vertical pump pipe 240 using a conversion installation device is performed after the integral steel platform formwork 500 is raised, without measurement barriers, and thus accurately locates the starting standard section of the (N+1)th vertical pump pipe 240.
