[0002] When installing some special equipment in the foundation pit, there are often requirements for the installation environment, such as waterproofing and heat insulation.

[0003] There is a special equipment that requires an absolutely waterproof environment during installation. The inner wall of the environment is cylindrical, and the verticality requirement for the side wall of the environment is extremely high. It is necessary to maintain the extremely high verticality requirement when the side wall has a high height. The conventional casting method is to cast in multiple stages from bottom to top, only one stage is cast each time, and real-time measurement is performed after each stage solidifies. If a large error is found, it is repaired immediately. If the repair still cannot achieve the corresponding accuracy, it needs to be dismantled and re-cast. This method has high economic and time costs and is difficult to complete within the construction period. Summary of the invention

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0041] An intelligent forming template for a foundation pit for placing high-precision equipment, referring to Figures 1 to 6, including a fixing frame 1, a supporting frame 2, an inner formwork 3, a first adjusting mechanism 4, a first outer formwork 5 and a second adjusting mechanism 6. Two fixing frames 1 are provided and are located on both sides of the area to be poured. The supporting frame 2 is fixedly mounted on the fixing frame 1 and is located above the area to be poured. The inner formwork 3 is installed below the supporting frame 2, and the first adjusting mechanism 4 is connected between the supporting frame 2 and the inner formwork 3 to adjust the verticality of the inner formwork 3. Two first outer formworks 5 are provided, which are respectively connected to two fixing frames 1, and an area to be poured is formed between the two first outer formworks 5 and the inner formwork 3. A second adjusting mechanism 6 is provided between each fixing frame 1 and the corresponding first outer formwork 5 to adjust the verticality of the corresponding first outer formwork 5.

[0042] During operation, the precision of the inner formwork 3 and the first outer formwork 5 are adjusted respectively by the first adjusting mechanism 4 and the second adjusting mechanism 6, so that the cast building can meet the designed verticality requirement. The precision of the final formed building is improved by controlling the manufacturing precision of the formwork and the adjustment precision of the adjusting mechanism, and the requirements for the on-site construction environment and operators are reduced. In addition, this solution can form the building in one step, greatly reduce costs, and improve construction efficiency.

[0043] Furthermore, an adjustment gap is provided between the first outer formwork 5 and the casting base surface so that the first outer formwork 5 is suspended, thereby facilitating adjustment of the angle of the first outer formwork 5. Two second outer formworks 7 are provided on the outside of the first outer formwork 5, and the adjustment gap is closed after the two second outer formworks 7 are assembled. After the adjustment gap is left between the first outer formwork 5 and the casting base surface, the adjustment gap is blocked by the second outer formwork 7 so that the building can be formed in one time, reducing the possibility of leakage at the bottom of the first outer formwork 5, and after the building is formed, the part of the adjustment gap can be relatively easily cleared, which has little effect on the construction efficiency. The part of the adjustment gap can also be left unchanged, which can also play a role in enhancing the support for the building. The two second outer formworks 7 are fixedly connected with a first connecting ear 71, and the two second outer formworks 7 are connected and fixed by the first connecting ear 71.

[0044] It should be noted that the inner side wall of the second outer template 7 has a rubber deformation layer to reduce the possibility of a gap between the second outer template 7 and the first outer template 5 .

[0045] Specifically, the inner formwork 3 includes an inner side formwork 31, an inner bottom formwork 32 and a main rod 33. The inner side formwork 31 extends along the circumference of the inner formwork 3 to form a closed state, so as to cast and form the inner side wall of the building to be cast. The inner side formwork 31 can be cylindrical, rectangular, triangular prism or other shapes that can form a closed cross section. In the present application, the inner side formwork 31 is cylindrical. The inner bottom formwork 32 is fixedly connected to the bottom of the inner side formwork 31, so as to cast and form the inner bottom surface of the building to be cast. The inner formwork 3 adopts a steel mold to ensure the accuracy of the template after processing.

[0046] The bottom end of the main rod 33 is fixedly connected to the inner bottom mold 32, and the top end of the main rod 33 extends out of the inner mold 31 and is spherically hinged with the support frame 2, so that the angle of the inner mold plate 3 can be adjusted through the spherical hinge between the main rod 33 and the support frame 2. A plurality of reinforcing rods 331 are also fixedly connected between the main rod 33 and the inner wall of the inner mold 31 to enhance the connection strength between the main rod 33 and the inner mold plate 3.

[0047] The first adjustment mechanism 4 includes a first adjustment plate 41 and a first jack 42. There are four first adjustment plates 41 and four first jacks 42. The four first adjustment plates 41 are fixedly connected between the inner mold 31 and the main rod 33, and are arranged in a circumferential array along the main rod 33. The four first jacks 42 correspond to the four first adjustment plates 41 one by one. One end of each first jack 42 is hinged to the support frame 2, and the other end is ball-jointed to the first adjustment plate 41 to adjust the angle of the inner template 3. Each first jack 42 is arranged at 90 degrees along the circumference of the main rod 33 to achieve the angle setting of the inner template 3 in four directions. After the first jack 42 is adjusted, it is self-locking to achieve the initial fixation of the support frame 2 and the inner template 3.

[0048] It should be noted that the actual adjustment angle of the inner template 3 is extremely small, and in some cases may even be less than 1 degree.

[0049] In addition, a first fixing mechanism 43 is provided between the support frame 2 and the inner template 3. The first fixing mechanism 43 includes a first fixing plate 431 and a clamping assembly. There are four first fixing plates 431 and four clamping assemblies. The four first fixing plates 431 are fixedly connected to the inner mold 31. Four groups of clamping assemblies correspond to the four first fixing plates 431. Each group of clamping assemblies includes two clamping plates 432 fixedly connected to the support frame 2. A clamping gap for accommodating the first fixing plate 431 is provided between the two clamping plates 432. A locking bolt 433 is threadedly connected to each clamping plate 432. The head of each locking bolt 433 is used to tighten the first fixing plate 431, thereby locking the inner template 3. During operation, the clamping gap facilitates the movement of the first fixing plate 431 when the inner template 3 is adjusted in angle. After the angle of the inner template 3 is adjusted, the first fixing plate 431 is locked by the locking bolt 433 to reduce the possibility of shaking of the inner template 3 during the pouring process. When the locking bolts 433 are locked, first rotate one locking bolt 433 so that the head of the locking bolt 433 contacts one side of the first fixing plate 431, then rotate the other locking bolt 433 so that the other locking bolt 433 contacts the other side of the first fixing plate 431, and then tighten the two locking bolts 433 in sequence to complete the locking of the first fixing plate 431. In this embodiment, the positions of the four first fixing plates 431 coincide with the positions of the four first adjustment plates 41 along the radial direction of the main rod 33.

[0050] In another embodiment, referring to Figure 5 The first fixing plate 431 is staggered 45 degrees from the first adjusting rod along the circumference of the main rod 33, so that there are eight staggered fixing points between the support frame 2 and the inner template 3 along the circumference of the main rod 33, thereby improving the fixing strength of the support frame 2 and the inner template 3.

[0051] Specifically, the second adjustment mechanism 6 includes a rotating assembly 61, a rotating plate 62, and a second jack 63. The rotating assembly 61 is mounted on the fixed frame 1, and the output end of the rotating assembly 61 is connected to the rotating plate 62. A plurality of second jacks 63 are provided along the length direction of the rotating plate 62, and one end of each second jack 63 is hinged to the rotating plate 62, and the other end is hinged to the corresponding first outer template 5. The second jack 63 and the rotating assembly 61 cooperate to achieve angle adjustment of the first outer template 5 in four directions.

[0052] More specifically, the rotating assembly 61 includes a third jack 611, a rack 612 and a gear 613. The third jack 611 is fixedly mounted on the fixed frame 1, and the rack 612 is fixedly connected to the output end of the third jack 611. The gear 613 is fixedly connected to the rotating plate 62, and the gear 613 is meshed with the rack 612. Through the cooperation of the third jack 611, the gear 613 and the rack 612, it is convenient to drive the rotating plate 62 to rotate so as to adjust the angle of the first outer template 5.

[0053] In addition, a second fixing mechanism 64 is provided between the fixing frame 1 and the first outer template 5. The second fixing mechanism 64 includes a first ball joint seat 641, a second ball joint seat 642 and a telescopic rod 643. The first ball joint seat 641 is fixedly mounted on the first outer template 5, and the second ball joint seat 642 is fixedly mounted on the fixing frame 1. One end of the telescopic rod 643 is spherically jointed with the first ball joint seat 641, and the other end is spherically jointed with the second ball joint seat 642. Through the arrangement of the telescopic rod 643, the first ball joint seat 641 and the second ball joint seat 642, when the angle of the first outer template 5 is adjusted, the length of the first telescopic rod 643 can be adjusted according to the change of the first outer template 5. After the angle of the first outer template 5 is adjusted, the telescopic rod 643 is locked, and then the fixing frame 1 and the first outer template 5 are further locked.

[0054] The second connecting ears 51 are fixedly connected to the side walls of the first outer template 5 , and the two first outer templates 5 are fixed to each other via the second connecting ears 51 .

[0055] A construction method, referring to Figure 7 , including the following steps:

[0056] S1. Cast a protective building 8 in a foundation pit, and form a receiving area 81 in the protective building 8.

[0057] S2. Construct the first waterproof layer 82 on the bottom and side of the accommodation area 81. When constructing the first waterproof layer 82, first lay thick polymer wet-laid waterproofing membrane 821 on the bottom and side of the accommodation area 81. The height of the thick polymer wet-laid waterproofing membrane 821 laid on the side of the accommodation area 81 can be 1 meter, and the other areas on the side of the accommodation area 81 can be coated with 2mm thick JS composite waterproof coating. Then, 1-meter-high protection bricks 822 can be laid on the side of the accommodation area 81, and plaster can be applied on the top of the protection bricks 822 to improve the connection strength between the protection bricks 822 and the side of the accommodation area 81.

[0058] S3. A casting base surface is reserved on the bottom surface of the accommodation area 81, and the height of the casting base surface is higher than other positions on the bottom surface of the accommodation area 81 to reduce the possibility of water affecting the installation of the building 9. The casting base surface 83 can be paved with 304 stainless steel plates to raise the height of the casting base surface 83 and fully waterproof.

[0059] S4, pouring the installation building 9 on the pouring base surface, the installation building 9 is poured by the above-mentioned intelligent forming template for the foundation pit where the high-precision equipment is placed, including the following steps:

[0060] S41 , hoisting the fixing frame 1 into the accommodating area 81 , and fixing the fixing frame 1 on the bottom surface of the accommodating area 81 .

[0061] S42, installing the steel cage on the inner formwork 3, and installing the first adjustment mechanism 4 and the inner formwork 3 on the support frame 2.

[0062] S43, hoisting the support frame 2, and fixing the support frame 2 on the fixing frame 1, and then adjusting the angle of the inner template 3 by the first adjusting mechanism 4 until the verticality of the inner template 3 meets the design requirements.

[0063] S44. Install the second adjustment mechanism 6 and the first outer formwork 5 on each fixing frame 1, and adjust the angle of the first outer formwork 5 by the second adjustment mechanism 6 until the angle of the first outer formwork 5 reaches the set requirement, and the two first outer formworks 5 are spliced ​​to form a pouring area between the inner formwork 3.

[0064] S45, pouring concrete into the area to be poured to form the installation building 9.

[0065] It should be noted that, in another embodiment, the first outer template 5 may be installed on the fixing frame 1 first, and then the fixing frame 1 may be hoisted into the accommodating area 81 . When adjusting the inner template 3 , space avoidance may be achieved by retracting the second jack 63 .

[0066] S5. A second waterproof layer 91 is constructed on the outer and inner walls of the installation building 9. The second waterproof layer 91 can be made of JS composite waterproof coating with a thickness of 2 mm. When constructing the second waterproof layer 91, the inner wall of the installation building 9 can be further corrected to ensure that the verticality meets the accuracy requirements. A drain port is set on the bottom surface of the edge area of ​​the accommodation area 81 to drain the accumulated water. A ladder 84 can be installed on the side wall of the accommodation area 81 so that when the drain port is blocked, the operator can move to the accommodation area 81 and clear it.

[0067] During operation, the protective building 8 is constructed first, and then the first waterproof layer 82 is constructed on the side and bottom of the accommodating area 81 to achieve a waterproof effect. At the same time, a relatively high casting base surface is reserved so that even if water enters the accommodating area 81, the water will not directly affect the installation building 9. Subsequently, the second waterproof layer 91 is constructed on the outer wall of the installation building 9 to further ensure the dryness of the interior of the installation building 9, so as to achieve absolute waterproofing and reduce the possibility of water entering the installation building 9 and affecting the high-precision equipment in the installation building 9.

[0068] At the same time, because the high-precision equipment is installed inside the installation building 9, the accuracy of the inner template 3 is adjusted first. If the accuracy requirement of the inner template 3 is met, the accuracy requirement of the inner wall of the installation building 9 is met. Then the first outer template 5 is installed and adjusted to form the area to be poured. At the same time, the steel cage is put on the inner template 3 at the beginning, so that the steel cage can be prefabricated, and an integral steel cage can be used, which has higher strength. While improving construction efficiency, the overall strength of the installation pouring is guaranteed.

[0069] Working principle: The precision of the inner formwork 3 and the first outer formwork 5 are adjusted respectively by the first adjusting mechanism 4 and the second adjusting mechanism 6, so that the building after casting can meet the designed verticality requirement. The precision of the final formed building is improved by controlling the manufacturing precision of the formwork and the adjustment precision of the adjusting mechanism, and the requirements for the on-site construction environment and operators are reduced. In addition, this solution can form the building in one step, greatly reduce costs, and improve construction efficiency.

[0070] After an adjustment gap is left between the first outer formwork 5 and the casting base surface, it is convenient to adjust the angle of the first outer formwork 5. At the same time, the adjustment gap is sealed with the second outer formwork 7 so that the building can be formed in one time, reducing the possibility of leakage at the bottom of the first outer formwork 5. After the building is formed, the part of the adjustment gap can be easily cleared, which has little impact on the construction efficiency.

[0071] The clamping gap facilitates the movement of the first fixing plate 431 when the angle of the inner template 3 is adjusted. After the angle of the inner template 3 is adjusted, the first fixing plate 431 is locked by the locking bolt 433 to reduce the possibility of shaking of the inner template 3 during the pouring process.

[0072] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
