Description

Technical Field

[0001] The invention relates to the field of bridge construction, and in particular to a flatness construction device and a leveling method for a cast-in-place section of a bottom section of a glued pier. Background Art

[0002] There are generally two ways to construct prefabricated piers. One is wet splicing. After the cast-in-place section of the pier bottom section is constructed, it is spliced ​​with the prefabricated pier sections by pouring concrete on site. The other is dry splicing. After the cast-in-place section of the pier bottom section is constructed, it is glued together with the prefabricated pier sections. Some cross-sea high-speed railway bridge piers are constructed using dry splicing. Dry splicing has higher requirements for the surface flatness accuracy of the cast-in-place section of the pier bottom section. Generally, the surface flatness accuracy of the cast-in-place section of the pier bottom section is required to be 2mm to ensure the gluing and assembly accuracy with the prefabricated pier sections.

[0003] In the related art, the surface flatness of the cast-in-place concrete section of the pier body bottom section is generally constructed by multi-point elevation measurement. On the concrete formwork of the cast-in-place section of the pier body bottom section, several pier height measurement points are arranged, and the elevation of each measurement point is measured by a level. The theoretical elevation of the top surface of the cast-in-place concrete section of the pier body bottom section is marked on its formwork to control the surface flatness of the cast-in-place concrete section of the pier body bottom section. This method has low measurement accuracy on the one hand, and it is difficult to uniformly control the construction flatness of the overall surface of the cast-in-place concrete section through multi-point elevation measurement; on the other hand, it is inefficient, and multi-point elevation measurement, marking and construction work are time-consuming and laborious. Summary of the invention

[0004] The present application provides a flatness construction device and leveling method for the cast-in-place section of the bottom section of a glued pier body, which can solve the problem in the prior art that the concrete surface flatness requirement of the cast-in-place section of the bottom section of the pier body is relatively high, and the existing leveling means require multi-point elevation measurement, which makes it difficult to uniformly control the construction flatness of the overall surface of the cast-in-place section concrete. At the same time, the multi-point elevation measurement, marking and construction work are time-consuming and labor-intensive technical problems.

[0013] In one embodiment, an electric sliding wheel for traveling along the sliding guide rail is provided in the sliding groove.

[0014] In one embodiment, a flattening roller is provided at the bottom of the flattening rod and is located between the two sliding grooves.

[0015] In a second aspect, the embodiment of the present application provides a leveling method, which is implemented based on the above-mentioned flatness construction device for the cast-in-place section of the bottom section of the glued pier body. The leveling method specifically includes:

The automated control method not only improves the construction accuracy, but also reduces the complexity and error rate of manual operation.

The entire flatness construction device can maintain a high degree of coordination and consistency during the adjustment process, thereby ensuring that the cast-in-place section to be leveled achieves an ideal leveling effect.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] The embodiment of the present application provides a flatness construction device and leveling method for the cast-in-place section of the bottom section of a glued pier body, which can solve the problem in the prior art that the concrete surface flatness requirement of the cast-in-place section of the bottom section of the pier body is relatively high, and the existing leveling means require multi-point elevation measurement, which makes it difficult to uniformly control the construction flatness of the overall surface of the cast-in-place section concrete. At the same time, the multi-point elevation measurement, marking and construction work are time-consuming and labor-intensive technical problems.

[0031] In the first aspect, the present application provides a flatness construction device for the cast-in-place section of the bottom section of a glued pier body, including a guide rail assembly and a leveling assembly. When the assembly is completed, the leveling assembly is mainly used to adjust the levelness of the guide rail assembly itself, and the guide rail assembly, under the adjustment and control of the leveling assembly, directly acts on the upper surface of the cast-in-place section to be leveled, stably guiding the flow and distribution of concrete. The two work together to complete the leveling work of the cast-in-place section to be leveled.

[0032] Specifically, Figure 1 A schematic diagram of a structural flatness construction device for a cast-in-place section of a glued pier body bottom section provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the flatness construction device in the present application includes two sets of guide rail assemblies arranged opposite to each other, the guide rail assemblies include a sliding guide rail 2 and a support frame unit 1 for supporting the sliding guide rail 2, and a flattening unit 3 is provided between the two guide rail assemblies, one end of the flattening unit 3 is slidably connected to the sliding guide rail 2 of one guide rail assembly, and the other end is slidably connected to the sliding guide rail 2 of the other guide rail assembly, and a longitudinal lifting unit 4 is provided at the bottom of the support frame unit 1;

[0033] The two groups of support frame units 1 are respectively used to be arranged on the two side edges of the concrete pouring mold to provide necessary support for the sliding guide rails 2. Each support frame unit 1 supports a sliding guide rail 2, and the flattening unit 3 spans the top surface of the concrete pouring mold, and the two ends of the flattening unit 3 are respectively connected to the two sliding guide rails 2, and can be laterally translated along the sliding guide rails 2. After the assembly is completed, the bottom of the flattening unit 3 protrudes from the bottom of the sliding guide rails 2, so that the bottom surface of the flattening unit 3 contacts the upper surface of the cast-in-place section to be leveled. At the same time, the flattening unit 3 is translated on the sliding guide rails 2 to level the cast-in-place section to be leveled. Based on the structural linkage, the height and levelness of the support frame unit 1 are equivalent to the height and levelness of the sliding guide rails 2. The height and levelness adjustment of the two support frame units 1 are achieved through the longitudinal jacking units 4 arranged at their respective bottoms, thereby ensuring that the flattening unit 3 maintains the correct height and horizontal posture during the leveling process.

[0034] Furthermore, the leveling component includes a leveling data acquisition unit for calculating the height difference between the actual elevation of the top surface of the sliding guide rail 2 and the theoretical elevation of the sliding guide rail 2, and a leveling control unit for adjusting the lifting height of the longitudinal lifting unit 4 based on the height difference so that the height difference is within the allowable deviation range.

[0035] The leveling data acquisition unit is responsible for calculating the height difference between the actual elevation of the top surface of the sliding guide rail 2 and the theoretical elevation, which usually involves using high-precision measuring equipment to measure the actual elevation of the top surface of the sliding guide rail 2 and compare it with the preset theoretical elevation. The leveling data acquisition unit also includes a data processing module for processing and analyzing the measurement data to obtain accurate height difference information. In a possible implementation of the present application, the leveling data acquisition unit may include measuring devices such as an electronic laser rangefinder and an electronic level.

[0036] The leveling control unit adjusts the lifting height of the longitudinal lifting unit 4 based on the height difference information provided by the leveling data acquisition unit, wherein the leveling control unit is electrically connected to the longitudinal lifting unit 4, and the leveling control unit may include one or more controllers, which determine the required lifting height adjustment amount according to the height difference, and send a control signal to the longitudinal lifting unit 4. The longitudinal lifting unit 4 makes corresponding adjustments based on the received control signal to adjust the actual elevation of the top surface of the sliding guide rail 2 into place. After the adjustment is completed, the flattening unit 3 starts to slide along the sliding guide rail 2 to level the cast-in-place section to be leveled.

[0037] The flatness construction device in the present application is provided with a guide rail assembly and a flattening unit 3. The flattening unit 3 spans the top surface of the concrete pouring mold and can perform leveling work while moving along the guide rail assembly. By providing a leveling data acquisition unit and a leveling control unit, the sliding guide rail 2 can be adjusted to within the allowable deviation range according to a preset theoretical elevation before the leveling work begins, thereby ensuring the correct height and horizontal posture of the flattening unit 3, thereby achieving high precision, standardization, high efficiency and automation of the entire leveling work.

[0038] Furthermore, Figure 2 A structural schematic diagram of a support frame unit 1 in a device for flatness construction of a cast-in-place section of a bottom section of a glued pier provided in an embodiment of the present application, as shown in FIG. Figure 2 As shown, in a possible embodiment, the support frame unit 1 includes two oppositely arranged frames, one end of the sliding guide rail 2 is connected to the top of one of the frames, and the other end is connected to the top of the other frame. The two frames are separately arranged, and are respectively used to connect the two sides of the same side of the concrete pouring mold, that is, there are four groups of frames in this embodiment, and the four frames are respectively arranged at the four corners of the concrete pouring mold. The two frames on the same side jointly support the same sliding guide rail 2 to jointly form a stable support system for stable displacement of the flattening unit 3. At the same time, the two frames on the same side are separately arranged and respectively connected to the two ends of a sliding guide rail 2. Therefore, this also means that the longitudinal jacking unit 4 can independently adjust the two frames to ensure that the two ends of the same sliding guide rail 2 are at the same height, thereby improving the overall adjustment accuracy of the guide rail assembly.

[0039] In a possible embodiment, the two frames in the support frame unit 1 can also be a whole. Under the premise that the whole remains horizontal, the longitudinal jacking unit 4 only needs to adjust the height of the whole, so that the horizontal heights of the two groups of support frame units 1 are equal and are both within the allowable deviation range.

[0040] For further information, see Figure 2 The frame includes a horizontal support plate 101, and a mold connecting rod 102 connected to the inner side of the horizontal support plate 101, and a track support plate 103 for connecting the sliding guide rail 2 is longitudinally provided on the top surface of the horizontal support plate 101. One end of the mold connecting rod 102 is used to connect the concrete pouring mold, and the other end is connected to the inner wall of the horizontal support plate 101 facing the concrete pouring mold, which is mainly used to ensure the connection stability of the frame. The track support plate 103 is longitudinally arranged on the top surface of the horizontal support plate 101 and is separated from the horizontal support plate 101. The top of the track support plate 103 is used to connect the sliding guide rail 2.

[0041] Furthermore, the longitudinal lifting unit 4 includes a CNC jack 401 longitudinally arranged below the horizontal support plate 101. The CNC jack 401 is electrically connected to the leveling assembly and is controlled by the leveling assembly for lifting and lowering. The telescopic end of the CNC jack 401 penetrates the horizontal support plate 101 and is connected to the bottom of the track support plate 103. The fixed end of the CNC jack 401 is used to be fixed to the ground or other supporting base. During the adjustment process, the horizontal support plate 101 and the sliding guide rail 2 move synchronously driven by the CNC jack 401.

[0042] Each horizontal support plate 101 may be provided with a CNC jack 401 located at its center point, or two CNC jacks 401 located at both ends thereof may be provided, which is not limited in the present application. In combination with the above description, in a possible implementation, when the frame is divided into four independent groups, the number of the longitudinal lifting units 4 is also four groups, so as to independently and accurately adjust each frame.

[0043] Furthermore, Figure 3 A bottom view of a flattening unit 3 in a flatness construction device for a cast-in-place section of a bottom section of a glued pier provided in an embodiment of the present application, as shown in FIG. Figure 3 As shown, the flattening unit 3 includes a flattening rod 301, and sliding grooves 302 are provided at both ends of the bottom of the flattening rod 301 along the width direction of the flattening rod 301. The sliding grooves 302 are set through, and the width of the sliding grooves 302 is greater than the diameter of the sliding guide rail 2, so that the flattening unit 3 can be placed on the sliding guide rail 2 through the two sliding grooves 302. At the same time, based on the movement of the flattening rod 301, in order to reduce the friction between the sliding guide rail 2 and the sliding groove 302, ensure the movement stability of the flattening rod 301, and also to improve the automation performance, an electric sliding wheel 303 for walking along the sliding guide rail 2 is provided in the sliding groove 302. The electric sliding wheel 303 is also electrically connected to the leveling component. When the leveling component completes the adjustment of the support frame unit 1 and the sliding guide rail 2, the electric sliding wheel 303 is controlled to walk along the sliding guide rail 2.

[0044] Furthermore, a flattening roller 304 located between two sliding grooves 302 is provided at the bottom of the smoothing rod 301, and the flattening roller 304 directly contacts the upper surface of the cast-in-place section to be leveled. A second groove 305 is provided on the bottom surface of the smoothing rod 301 along the length direction of the smoothing rod 301, and a rotating shaft 306 is provided in the second groove 305. The rotating shaft 306 is arranged along the length direction of the second groove 305, and the two ends of the rotating shaft 306 are respectively rotatably connected to the two opposite inner walls of the second groove 305. The flattening roller 304 is sleeved on the outer periphery of the rotating shaft 306 and is coaxially arranged with the rotating shaft 306. The level of the smoothing rod 301 is equivalent to the level of the flattening roller 304. After the adjustment of the support frame unit 1 is completed, the flattening roller 304 will rotate with the movement of the smoothing rod 301, thereby guiding the flow and distribution of concrete on the cast-in-place section to be leveled.

[0045] The working mechanism of the flatness construction device in the present application is as follows: the two support frame units 1 are respectively connected to the concrete pouring mold through the mold connecting rod 102, so that the flattening unit 3 spans above the concrete pouring mold, and then the actual elevation of the sliding guide rail 2 is obtained through the leveling data acquisition unit. At this stage, since the four frames can be adjusted independently, there may be slight differences in the height of each frame, which in turn leads to inconsistent heights at both ends of the same sliding guide rail 2. Therefore, in order to ensure the accuracy of construction, it is preferred to obtain the actual elevations of both ends of the top surface of the sliding guide rail 2, and then calculate the height difference between each actual elevation and the theoretical elevation respectively. The leveling control unit drives the longitudinal jacking unit 4 located at the bottom of each frame to independently adjust according to the height difference of each frame, so that the final height of the sliding guide rail 2 is within the allowable deviation range of the theoretical elevation, and finally drives the flattening unit 3 to slide along the sliding guide rail 2 to complete the leveling work.

[0046] The flatness construction device in the present application can quickly and accurately obtain the actual elevation of the sliding guide rail 2 and calculate the height difference between the actual elevation and the theoretical elevation by setting a leveling data acquisition unit, which greatly improves the efficiency of the construction process and reduces errors and delays caused by inaccurate measurements. The leveling control unit drives the longitudinal jacking unit 4 to perform longitudinal adjustment through the calculation result of the leveling data acquisition unit. The automated control method not only improves the construction accuracy, but also reduces the complexity and error rate of manual operation. Based on the structural linkage effect, the action of the longitudinal jacking unit 4 will directly affect the horizontality and height of the flattening unit 3 to complete the leveling work of the cast-in-place section to be leveled. The entire flatness construction device can maintain a high degree of coordination and consistency during the adjustment process, thereby ensuring that the cast-in-place section to be leveled achieves an ideal leveling effect.

[0047] In a second aspect, the present application further provides a leveling method, which is implemented based on the above-mentioned glued pier body bottom section cast-in-place section flatness construction device. Specifically, the leveling method includes the following steps:

[0048] S1: Obtain the actual elevation of the top surface of the sliding guide rail 2, and calculate the height difference between the actual elevation and the theoretical elevation of the top surface of the sliding guide rail 2;

[0049] The leveling data acquisition unit acquires the actual elevation of the top surface of the sliding guide rail 2, that is, the vertical distance between the top surface of the sliding guide rail 2 and the ground. This is because, firstly, the top surface test point of the sliding guide rail 2 is easier to acquire and locate, and secondly, there may be a deviation between the design thickness and the actual thickness of the sliding guide rail 2. Therefore, taking the actual elevation of the top surface of the sliding guide rail 2 as the standard helps to improve the adjustment accuracy. At the same time, the sliding guide rail 2 is a linear rod body. Therefore, in a possible implementation manner, it is preferred to acquire the actual elevations of the two ends of the top surface of the sliding guide rail 2. The actual elevations of the two ends of the top surface of the sliding guide rail 2 are consistent, which can ensure the levelness of the sliding guide rail 2. That is to say, in the data acquisition stage of this embodiment, the leveling data acquisition unit acquires a total of four values, which are the actual elevations of the top surfaces at both ends of the two sliding guide rails 2, and calculates the height difference between the actual elevations of the four places and the same theoretical elevation.

[0050] S2: adjusting the lifting height of the longitudinal lifting unit 4 according to the height difference so that the height difference is within the allowable deviation range.

[0051] The leveling data acquisition unit transmits the calculation result to the leveling control unit, and the leveling control unit controls the longitudinal lifting units 4 located at the bottom of the two support frame units 1 to rise and fall respectively, so that the sliding guide rails 2 on the two support frame units 1 are horizontal and the actual elevation is within the allowable deviation range of the theoretical elevation. Combined with the description in S1, in a possible implementation mode, the longitudinal lifting unit 4 separately adjusts the two ends of the same support frame unit 1 to directly act on the two ends of the sliding guide rail 2 until the actual elevations of the top surfaces at both ends of the two sliding guide rails 2 are within the allowable deviation range of the theoretical elevation.

[0052] Furthermore, Figure 4 This is a schematic diagram of the theoretical elevation of the top surface of the sliding guide rail in the leveling method provided in the embodiment of the present application, such as Figure 4 As shown, in step S1, the determination method for the theoretical elevation of the top surface of the sliding guide rail 2 specifically includes:

[0053] S101: Obtaining the protruding height of the bottom surface of the flattening unit 3 from the bottom surface of the sliding guide rail 2, and the thickness of the sliding guide rail 2;

[0054] S102: Add the protruding height, thickness and qualified elevation of the cast-in-place section to be leveled to obtain the theoretical elevation of the top surface of the sliding guide rail 2.

[0055] The theoretical elevation is a predetermined height, at which the flattening unit 3 installed on the bottom surface of the sliding guide rail 2 just fits against the upper surface of the cast-in-place section to be leveled. During the leveling work, the flattening unit 3 directly acts on the surface of the cast-in-place section to be leveled, which means that the horizontal position of the bottom surface of the flattening unit 3 is lower than the bottom surface position of the sliding guide rail 2. At the same time, the sliding guide rail 2 itself also has a certain thickness. Therefore, the theoretical elevation needs to take into account the qualified elevation of the cast-in-place section to be leveled, the protruding height of the bottom surface of the flattening unit 3 outside the bottom surface of the sliding guide rail 2, and the thickness of the sliding guide rail 2. The sum of the three is the theoretical elevation of the top surface of the sliding guide rail 2.
