[0023] like Figures 1-2 As shown, a slipform concrete pouring construction system of this utility model includes a hydraulic lifting device for lifting the slipform.

[0024] A leveling device used for measuring the levelness of a sliding mold;

[0025] Deviation measuring device, used for measuring the vertical deviation of the sliding mode;

[0026] A display device is used to display the measurement data of the leveling device and the deviation measuring device;

[0027] The leveling device and the deviation measuring device are connected to the display device, which is installed on the control cabinet and remotely displayed on the screen in the control room. The control cabinet is used to manually adjust the hydraulic lifting device.

[0028] Settlement monitoring device for measuring the vertical deviation and levelness of the slipform;

[0029] A PLC control unit is used to connect to a settlement monitoring device and control some or all of the actions of a hydraulic lifting device.

[0030] The hydraulic lifting device is a hydraulic leveling internal climbing slipform system, which includes slipform template, operating panel, auxiliary panel, lifting frame, support rod (commonly known as "climbing rod"), and hydraulic system.

[0031] Slipform is a mold used for concrete forming. Its quality (mainly including rigidity and surface smoothness) directly affects the forming and appearance quality of the poured concrete. To ensure construction quality, slipform is made of steel plates thicker than 5mm, with angle steel, strip steel, or channel steel used as stiffening ribs, and welded and fixed to the operating panel truss. The formwork height is selected according to the size of the structure, at 1m, 1.25m, and 1.5m. The formwork taper is controlled at 3-5mm, that is, in the vertical direction, the upper opening of the formwork is 1.5-2.5mm larger than the design size of the lining structure, and the lower opening is 1.5-2.5mm smaller than the design size.

[0032] The slipform operating platform is the main load-bearing component of the slipform structure, bearing loads from work and materials. It also serves as the supporting component of the slipform body and the main working platform for slipform construction. It adopts an integral steel truss structure. During concrete construction, the vertical load and lateral forces are significant. To ensure the strength and rigidity of the operating platform, the slipform truss is constructed by welding angle steel or channel steel into a double truss with a width of 1m and a height of 1m, 1.2m, or 1.5m. The trusses are connected by bolts or welding to form a unified structure.

[0033] The slipform auxiliary platform is a working platform for concrete finishing, curing, and handling of embedded parts. It is suspended below the slipform operating panel. To facilitate construction personnel to check the quality of the concrete after demolding, repair local defects in the concrete in a timely manner, remove embedded parts, and water the concrete surface for curing, the platform is suspended at a height of about 2m. The auxiliary panel is welded with ∠50×5mm angle steel or 5# channel steel, and is fully covered with 2.5mm checkered steel plate. It is suspended by hooks made of Φ20 round steel or bolted to the truss of the operating panel.

[0034] The slipform lifting mechanism mainly consists of a steel lifting frame, commonly known as a "climbing platform." Jacks installed on the upper part of the lifting frame transfer the static load and dynamic construction load of the entire slipform system to the climbing rods, which then apply the load-bearing capacity to the poured concrete structure. Depending on the required location, the lifting frame can be either an "F-shaped frame" or an "open-shaped frame." The "F-shaped frame" uses 16# channel steel welded together as columns, 20mm steel plates as the face plates, and 10mm steel plates as the ribs. The "open-shaped frame" uses 20# I-beams as columns, 20# channel steel for the flat connections, and 20mm steel plates as the face plates.

[0035] The lower part of the slipform support rod is supported on the concrete structure under construction, while the upper part passes through the through-hole of the hydraulic jack, bearing the entire load of the slipform. It is extended in 3-meter sections as the slipform rises, with the submerged portion permanently remaining within the concrete structure. The support rod is selected in conjunction with the hydraulic jack and uses φ48×3.5mm or φ70×5mm welded steel pipe.

[0036] The slipform hydraulic system mainly consists of a hydraulic control console, hydraulic jacks, and hydraulic oil pipelines. The hydraulic control console is a YZKT or YKT series automatic leveling hydraulic control console. The hydraulic jacks are GYD or QYD series jacks. The main hydraulic oil pipe is φ16mm, and the branch pipes are φ8mm. They are connected to the hydraulic control console and hydraulic jacks in groups using direct pipe fittings and distributors to form the hydraulic system. The hydraulic control console is placed on the slipform operating panel; the hydraulic jacks are fixed to the lifting frame panel with M18 bolts; the hydraulic pipelines are laid through the cavities of the operating panel's double truss structure.

[0037] The leveling device and the deviation measuring device are connected to the display device, and the horizontal and vertical deviation data detected by the leveling device and the deviation measuring device are displayed through the display device.

[0038] The display device is installed on the control cabinet and can be remotely displayed on the screen in the control room; the screen in the control room is used to remotely monitor the operating status of the slipform concrete pouring construction system.

[0039] The hydraulic lifting device includes multiple sets of hydraulic circuits, such as hydraulic circuit 1, hydraulic circuit 2, hydraulic circuit 3, hydraulic circuit 4, hydraulic circuit 5, hydraulic circuit 6, hydraulic circuit 7, hydraulic circuit 8, hydraulic circuit 9, hydraulic circuit 10, hydraulic circuit 11, and hydraulic circuit 12. Each set of hydraulic circuits is equipped with a solenoid valve, and the solenoid valve is connected to the PLC.

[0040] The leveling device includes multiple leveling instruments, such as leveling instrument L1, leveling instrument L2, leveling instrument L3, leveling instrument L4, leveling instrument L5, leveling instrument L6, leveling instrument L7, leveling instrument L8, leveling instrument L9, leveling instrument L10, leveling instrument L11, leveling instrument L12, leveling instrument L13, and leveling instrument L14. These leveling instruments are evenly distributed on the sliding formwork. The operator judges the levelness of the sliding formwork by observing the data of the multiple leveling instruments displayed on the display device.

[0041] The deviation measuring device includes multiple deviation measuring instruments, such as deviation measuring instrument V1, deviation measuring instrument V2, deviation measuring instrument V3, and deviation measuring instrument V4. The deviation measuring instruments are evenly distributed on the side of the sliding formwork operating plate truss or lifting frame. The operator judges the vertical deviation of the sliding formwork by observing the data of multiple deviation measuring instruments.

[0042] The settlement monitoring device is a dynamic level settlement monitoring system from Shenzhen Anrui Technology Co., Ltd., used for measuring the vertical deviation and levelness of the sliding formwork and transmitting the measurement data to a PLC control device, thereby controlling the lifting and lowering actions of multiple sets of hydraulic lifting circuits.

[0043] The settlement monitoring device is fixedly installed on the side of the sliding formwork operating panel truss or lifting frame by bolts or by adhesive to the base plate;

[0044] The working process of the slipform concrete pouring construction system of this utility model is as follows: A settlement monitoring device monitors the vertical deviation and levelness of the slipform and transmits the measurement data to a PLC control device. The PLC control device controls the lifting actions of hydraulic circuits 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 to restore the slipform to its initial vertical deviation and levelness. During this process, workers verify the vertical deviation data and angular deflection data measured by the leveling device and the deviation measuring device. The vertical deviation and horizontal angle status of the slipform are monitored to more accurately control its state. For example, if the vertical deviation and angle deflection data measured by the leveling and deviation measuring devices fail to return to the initial vertical deviation and horizontal state due to unexpected displacement of the settlement monitoring device or local deformation of the slipform, but the settlement monitoring device shows that the slipform has returned to the initial vertical deviation and horizontal state, the operator can manually adjust the corresponding hydraulic lifting circuit to restore the slipform to the initial vertical deviation and horizontal state, and then continue the lifting and lowering of the slipform. Through the above-mentioned automatic control of slipform lifting and manual verification, more accurate slipform adjustment can be achieved.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of the implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
