Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a floating building translation and underground structure construction method. Background Art

[0002] In the process of urban renewal, it is particularly important to coordinate the relationship between existing buildings and new buildings. Existing buildings with historical significance or continued use value need to be preserved in urban renewal. In urban renewal, it is often necessary to move buildings from their old sites or temporarily move them to temporary sites and then move them back. Therefore, building translation is an indispensable technical means in urban renewal. By moving the entire building to a new location, it is possible to protect its original structure and appearance without affecting the overall process of urban renewal. In this way, it is possible to balance inheritance and development in urban renewal and organically combine the history and modernity of the city.

[0003] In the process of urban renewal, the full utilization of underground space is also crucial. The land resources in the central city are limited, so the development of underground space has become an efficient way to make more full use of the space in the central city. Through reasonable planning and design, the underground space can be transformed into commercial, cultural or entertainment facilities to improve the functionality of the central city. The construction of new underground space under existing buildings can not only solve the problem of limited land resources, but also alleviate the traffic pressure in the central city. The development of underground space can include infrastructure such as underground parking lots and traffic passages to provide urban residents with a more convenient travel experience. At the same time, this will also help improve the quality of life in the city and make the central city a more livable, business-friendly and tourist-friendly space. In actual operation, it is necessary to conduct in-depth research on the history and culture of the city and accurately evaluate the value and potential of each existing building. At the same time, the translation of buildings and the development of underground space require scientific and reasonable planning and technical support to ensure that the historical heritage of the city can be protected and the overall improvement of urban functions can be achieved during the renewal process.

[0004] The existing building translation methods commonly used are slide-type translation, walking-type translation, and vehicle-mounted translation. Among them, slide-type translation and walking-type translation require the use of jacks to push and tilt the cylinder in the horizontal direction. The translation process is limited by the stroke of the jack and is divided into small sections, so the translation speed is slow. Although the vehicle-mounted translation can move continuously and the translation speed is fast, the vehicle-mounted translation has strong requirements on the equipment of the translation vehicle, and the front and back of the ordinary translation vehicle need to occupy a certain space, so it is not suitable for translation in site conditions with small space spacing between buildings. In addition, the above three commonly used translation methods are not combined with underground space components, and it is difficult to avoid structural disturbances caused by uneven ground during the translation process.

[0005] Therefore, it is necessary to provide a method for floating building translation and underground structure construction, which can solve the problems of low efficiency of slide-type translation and walking-type translation in the existing technology, high requirements for equipment and space for vehicle-mounted translation, and susceptibility to disturbance by uneven ground. Summary of the invention

[0006] The purpose of the present invention is to provide a method for floating building translation and underground structure construction, which can solve the problems of low efficiency of slideway translation and walking translation in the prior art, high requirements for equipment and space for vehicle-mounted translation, and susceptibility to disturbance by uneven ground.

[0024] The existing pile foundation of the building is used as the in-situ pile column, with the following requirements: (1) the load-bearing and performance performance of the existing pile foundation of the building can meet the requirements of the entire subsequent construction and structural service period; (2) the spatial position of the existing pile foundation of the building will not block the translation path of the building.

[0025] The tray system is formed by a combination of staggered beams, and holes are formed between the staggered beams;

[0026] The requirements of the pallet system are: (1) a reliable connection can be formed between the pallet system and the original piles and buildings; (2) there are pre-holes in the pallet system, which serve as the excavation opening and operation entrance and exit for digging the earth under the building; (3) the pallet system can meet the bearing capacity and deformation requirements of transferring all the loads of the upper building to the original piles.

[0030] The enclosure and water-stopping structure meet the following requirements: (1) the enclosure and water-stopping structure can meet the soil pressure outside the floating pool, the pressure of the floating liquid in the floating pool, and the load-bearing and performance of the structural system after molding; (2) the enclosure and water-stopping structure can prevent water from outside the floating pool from pouring in, and meet the requirement that the floating liquid in the floating pool does not overflow.

After the floating liquid is poured in, buoyancy is provided by elastic air bags and anti-collision air bags, so that the building is floated and translated from the original site to the translation site under the action of buoyancy, thereby avoiding to the greatest extent the possibility of damage to the building due to disturbance during the translation process. The translation process is safe and stable, and has higher translation efficiency than the slide-type translation and walking-type translation in the prior art, and has lower requirements on space and equipment than the vehicle-mounted translation in the prior art.

[0040] 2. The present invention uses a traction device, a lateral restraint device and a traction rope to apply traction to the pallet system and the building from different directions, thereby ensuring stable and efficient floating translation of the building under the action of traction at different angles, the translation path is accurately controllable, and the translation operation is simple and easy.

[0041] 3. The present invention constructs a pallet system and original piles under the building to replace the original foundation force system of the building, and constructs the piles at the translation site at the same time. Combined with the different stage heights of the floating liquid and the buoyancy of the elastic airbags and the anti-collision airbags, the force stability of the building at different construction stages is ensured, and the safety of the translation construction of the building is ensured. The original piles and the translation site piles can be used as temporary construction support structures of the building at the original site and the translation site, and can also be used as vertical force transmission components of the permanent underground structure.

DETAILED DESCRIPTION

[0050] The following is a further detailed description of a floating building translation and underground structure construction method proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0051] Please see attached Figure 1 , a floating building translation and underground structure construction method, comprising the following steps:

[0052] Please see attached Figure 2, Step 1: construct the original pile column 2 and the pallet system 3 under the building 1, so that the pallet system 3 connects the original pile column 2 and the building 1.

[0053] In step 1, a plurality of original piles 2 are constructed in the soil below the building 1, and a pallet system 3 is constructed at the bottom of the building 1, so that the original foundation of the building 1 is combined with the pallet system 3 to form a new foundation, and the pallet system 3 is temporarily connected to the plurality of original piles 2.

[0054] The in-situ pile column 2 may be a newly built pile column or an existing pile foundation of the building 1. The newly built in-situ pile column 2 shall meet the following conditions: (1) the in-situ pile column 2 shall be able to bear the load of the building 1 and the attached parts including the pallet system 3; (2) the location and arrangement of the in-situ pile column 2 shall not block the translation path of the building 1; and (3) the in-situ pile column 2 shall be able to be effectively connected to the pallet system 3 and be easily detached.

[0055] Preferably, the newly built in-situ piles 2 may be bored cast-in-place piles, steel pipe piles, etc., without limiting the type and quantity of the in-situ piles 2.

[0056] If the existing pile foundation of building 1 is used as the in-situ pile column 2, the requirements are as follows: (1) the load-bearing and performance performance of the existing pile foundation of building 1 can meet the requirements of the entire subsequent construction and structural service period; (2) the spatial position of the existing pile foundation of building 1 will not block the translation path of building 1.

[0057] The pallet system 3 is formed by staggered beams, and holes 31 are formed between the staggered beams. Preferably, the beams can be staggered orthogonally or non-orthogonally, and the pallet system 3 can be made of reinforced concrete, steel structure, or steel concrete. The pallet system 3 of a suitable type and shape can be selected according to the adaptability of the actual construction conditions.

[0058] The requirements of the pallet system 3 are as follows: (1) the pallet system 3 can form a reliable connection with the original pile column 2 and the building 1; (2) there is a pre-hole 31 in the pallet system 3, and the pre-hole 31 can be used as an excavation port and an operation entrance and exit for digging the earth under the building 1; (3) the pallet system 3 can meet the bearing capacity and deformation requirements of transferring all the loads of the upper building 1 to the original pile column 2.

[0059] Step 2: During the construction of the original site piles 2 and the pallet system 3, the relocated site piles 4 and the enclosure and water-stopping structure 5 can be constructed simultaneously. The enclosure and water-stopping structure 5 circumferentially surrounds the periphery of the relocated site and the original site.

[0060] The horizontal displacement pile column 4 can be used as a permanent structure after the overall completion of the structure, or as a temporary replacement structure during the construction process. The horizontal displacement pile column 4 can adopt the same construction method and arrangement method as the original site pile column 2, or can be adaptively constructed according to the actual construction conditions, which will not be repeated here.

[0061] The translation pile 4 should meet the following requirements: (1) The arrangement position of the translation pile 4 should not block the translation path of the building 1; (2) The translation pile 4 should be able to withstand the load of the building 1 translated to its upper part and the attached parts including the pallet system 3; (3) The translation pile 4 should be able to form an effective connection with the pallet system 3 and be able to withstand horizontal and vertical forces.

[0062] The enclosure and water-stopping structure 5 includes an enclosure structure and a water-stopping structure. Figure 2 In the figure, the retaining structure and the water-stop structure are drawn together, but in actual operation, the retaining structure and the water-stop structure can be set separately, and the retaining structure and the water-stop structure can be set to multiple layers respectively.

[0063] The enclosure and water-stopping structure 5 should meet the following requirements: (1) the enclosure and water-stopping structure 5 should be able to meet the soil pressure outside the floating pool, the pressure of the floating liquid 9 in the floating pool, and the load-bearing and performance of the structural system after molding; (2) the enclosure and water-stopping structure 5 can not only prevent the influx of water from outside the floating pool, but also meet the requirement that the floating liquid 9 in the floating pool does not overflow.

[0064] The top of the enclosure and water-stopping structure 5 may be formed with an upper extension section 51, and the upper extension section 51 extends upward to above the floor outside the floating pool.

[0065] The height of the upper extension section 51 can be adjusted according to the actual construction requirements. The upper extension section 51 should be able to meet the requirements of bearing capacity and preventing liquid from spilling. The upper extension section 51 can raise the plane of the floating liquid 9 in the floating pool to a level higher than the floor outside the floating pool, thereby compensating the draft height loss of the building 1 and the attached parts including the tray system 3 in the floating state through the upper extension section 51, and can also control the new elevation of the building 1 at the translation site.

[0066] Please see attached Figure 3 , Step 3: Excavate the earth inside the enclosure and water-stop structure 5 so that the vertical load of the building 1 is transferred to the original pile column 2 through the tray system 3.

[0067] Please see attached Figure 4 Step 4: After the earthwork is excavated until there is enough installation and operation space under the pallet system 3, an elastic airbag 32 is installed under the pallet system 3 and an anti-collision airbag 33 is installed at the edge of the pallet system 3.

[0068] After being inflated, the elastic airbags 32 can float on the floating liquid 9, thereby providing an upward supporting force for the building 1 and the pallet system 3. The number of the elastic airbags 32 can be adaptively selected according to actual load requirements.

[0069] The elastic airbag 32 should meet the following requirements: (1) After being fully inflated, the maximum buoyancy that the elastic airbag 32 can provide in the floating liquid 9 should be greater than 1.2 times the gravity of the building 1 and the attached parts including the pallet system 3; (2) The elastic airbag 32 should be able to meet the requirements of not aging during the construction process that affects the construction safety; (3) The elastic airbag 32 is reliably connected to the pallet system 3 and can be disassembled and replaced; (4) The arrangement position of the elastic airbag 32 should avoid blocking the translation path of the building 1; (5) The elastic airbag 32 has tear and puncture resistance. If the elastic airbag 32 is punctured, gas will leak out but it will not burst itself; (6) The elastic airbag 32 should have the functions of air intake and exhaust after being installed in place.

[0070] The anti-collision airbag 33 can also serve as an elastic airbag, and the anti-collision airbag 33 can provide buoyancy. The number of the anti-collision airbags 33 can be adaptively adjusted according to actual construction requirements. At the same time, the anti-collision airbags 33 located at the edge of the pallet system 3 can prevent the pallet system 3 from colliding with the enclosure and water-stopping structure 5 during translation. Preferably, the plane size of the pallet system 3 is not less than the plane size of the building 1, so that the anti-collision airbag 33 is located at the bottom periphery of the building 1 and the pallet system 3, and can collide with the enclosure and water-stopping structure 5 before the pallet system 3 and the building 1, thereby effectively protecting the building 1 when a collision occurs.

[0071] The anti-collision airbag 33 should meet the following requirements: (1) The anti-collision airbag 33 is arranged on the periphery of the pallet system 3 and the building 1, has good deformation ability, and can realize the buffering function of the collision with the enclosure and water-stopping structure 5; (2) The anti-collision airbag 33 should be able to meet the requirement of not aging that affects the construction safety during the construction process; (3) The anti-collision airbag 33 has tear resistance and puncture resistance. If the anti-collision airbag 33 is punctured, gas leakage will occur but the airbag itself will not explode; (4) The anti-collision airbag 33 should have the function of air intake and air exhaust after being installed in place.

[0072] Please see attached Figure 4 Step 5: After the earth excavation is completed, the horizontal bottom cover 14 in the enclosure and water-stop structure 5 is constructed as soon as possible to form a floating pool for the floating translation of the building 1.

[0073] The horizontal bottom seal 14 should meet the requirements of preventing water from outside the floating pool from pouring in and preventing the floating liquid 9 in the floating pool from overflowing. The horizontal bottom seal 14 is constructed using conventional processes, which will not be described in detail here.

[0074] Utilizing the underground space of the building 1 to form a floating pool can save additional construction measures and has lower requirements on equipment and space for translation construction.

[0075] Please see attached Figure 5 Step 6: Pour the floating liquid 9 into the excavated floating pool, and control the injection of the floating liquid 9 to reach the first stage water level line.

[0076] At the first stage water level, the buoyancy borne by the elastic airbag 32 and the anti-collision airbag 33 is equal to the gravity of the building 1 and the attached parts including the pallet system 3, that is, at the first water level, the original pile column 2 does not bear the load transmitted from the upper part.

[0077] Preferably, the floating liquid 9 can be water or other liquids, which can be adaptively selected according to actual construction requirements. Using the floating liquid 9 as a floating translation medium can achieve ideal floating translation of buildings without disturbance or tilt.

[0078] Step 7: Disconnect the connection between the original pile 2 and the pallet system 3.

[0079] Step 8: Control the floating liquid 9 injected into the floating pool to reach the second stage water level line, and disconnect the tray system 3 from the original pile column 2.

[0080] The height of the second-stage water level line can be adaptively adjusted according to the actual load conditions. At the second-stage water level line, the buoyancy generated by the elastic airbag 32 and the anti-collision airbag 33 can separate the pallet system 3 from the original pile column 2.

[0081] Please see attached Figure 6 Step 9: Install the traction device 6 on the enclosure and water-stopping structure 5 or the upper extension section 51, and connect the traction device 6 with the pallet system 3 through the traction rope 8, so that the building 1 is floated and translated from the original site to the translation site through the traction device 6 and the traction rope 8.

[0082] Preferably, the length direction of the traction rope 8 between the traction device 6 and the pallet system 3 is consistent with the translation direction. The traction device 6 can adopt equipment such as a winch to wind and release the traction rope 8, so as to use the traction rope 8 to apply traction to the pallet system 3 and the building 1 above it, thereby realizing the floating translation of the building 1.

[0083] Preferably, a plurality of traction devices 6 can be installed at intervals at both ends of the floating pond along the translation direction, and the number of traction devices 6 can be adaptively adjusted according to actual traction requirements.

[0084] In the step 9 , a lateral restraint device 7 is installed on the enclosure and water-stopping structure 5 or the upper extension section 51 , and the lateral restraint device 7 is connected to the tray system 3 via a traction rope 8 .

[0085] The length direction of the traction rope 8 between the lateral restraint device 7 and the pallet system 3 is not consistent with the translation direction. The lateral restraint device 7 can use the same device as the traction device 6. The lateral restraint device 7 and the traction device 6 are only different in installation direction and installation position. Preferably, the length direction of the traction rope 8 can be perpendicular to the translation direction to play a role of lateral restraint, so as to ensure that the translation trajectory of the building 1 during the translation process is consistent with the design requirements.

[0086] Preferably, multiple lateral restraint devices 7 can be installed at intervals at both ends of the floating pool along the vertical translation direction, and the number of lateral restraint devices 7 can be adaptively adjusted according to actual restraint requirements. The translation direction of the building 1 is controlled by the traction device 6 and the lateral restraint device 7, and the combined traction of different traction angles is used to ensure the stable translation of the building 1 along the designed translation direction.

[0087] Preferably, the lateral restraint device 7 may have a mobile function and may move synchronously with the translation of the building 1 to ensure an effective lateral restraint effect. The lateral restraint device 7 may use the upper extension section 51 as a reaction backstage. When the upper extension section 51 is used as a reaction backstage, it needs to meet the requirements of strength, deformation, crack resistance and impermeability.

[0088] Step 10: The floating liquid 9 is discharged to reach the third stage water level, the building 1 is placed on the translation site pile 4 through the pallet system 3, and the translation site pile 4 is connected to the pallet system 3.

[0089] Under the third stage water level line, the pallet system 3 is seated on the translation site piles 4 of the translation site, and a reliable connection is formed between the pallet system 3 and the translation site piles 4, but the vertical force of the building 1 and the attached parts including the pallet system 3 is still provided by the buoyancy of the elastic airbags 32 and the anti-collision airbags 33.

[0090] Step 11: Dismantle temporary translation equipment and facilities including the lateral restraint device 7, the traction device 6, the traction rope 8, the elastic airbag 32, and the anti-collision airbag 33.

[0091] Step 12: Drain the floating liquid 9 completely.

[0092] Step 13: Construct the underground space structure.

[0093] Please see attached Figure 6 The underground space structure includes an underground structure bottom plate 10, an underground structure beam plate 11, an underground structure enclosure 12 and an underground structure column 13. The underground space structure is constructed using conventional construction technology, which will not be described here.

[0094] The original-site piles 2 and the translated-site piles 4 can be used as permanent structural piles of the underground structure. Alternatively, according to design requirements, some of the original-site piles 2 and the translated-site piles 4 can be removed, and the remaining original-site piles 2 and the translated-site piles 4 together with the underground structure columns 13 and the underground structure enclosure 12 can form a vertical force transmission system of the underground structure.

[0095] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
