Description

Technical Field

[0001] The utility model relates to the field of viaduct construction, in particular to a blocking device for a reserved hole in a pier body. Background Art

[0002] Due to the differences in the structural form of the bridge cap beam, the height of the piers and the on-site construction conditions, there are many different methods for constructing the bridge cap beam. The more common construction methods include the cross-core steel rod method, the embedded steel corbel method, the floor-standing bracket method and the hoop method.

[0003] The method of cross-core steel rods is adopted for the construction of viaduct cap beams. Specifically, reserved holes are pre-buried in the piers, steel sections or high-strength steel rods are inserted into the holes and locked, and the steel sections support the support formwork and the weight of the entire cap beam. The advantages are: the weight of the support formwork and the entire cap beam is transmitted to the piers through the steel sections and borne by the piers. The force transmission path is simple and clear, and there is no problem of support sinking. The disadvantages are: after construction, two reserved through-holes with a diameter of 100 mm will appear in the pier body, affecting the appearance quality of the pier. Blocking the holes requires certain equipment resources, reduces the work efficiency during normal construction operations, increases labor costs, equipment resource costs, and has a low turnover rate. In addition, its processing is not only labor-intensive and time-consuming but also difficult to be satisfactory. There will also be certain safety hazards in the entire blocking process.

DETAILED DESCRIPTION

[0020] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0022] The utility model will be described in detail below with reference to the accompanying drawings. Figures 1 to 3 As shown: The device for sealing the reserved holes in the pier body described in this embodiment includes two first stop slurry plates 2 fixed together by a retractable first connecting plate 1, a first connecting pipe 3 arranged at the center of the first stop slurry plates 2, two second stop slurry plates 5 fixed together by a retractable second connecting plate 4, a second connecting pipe 6 arranged at the center of the second stop slurry plates 5, a tension bolt 7 for connecting the first stop slurry plate 2 and the second stop slurry plate 5 together through the first connecting pipe 3 and the second connecting pipe 6, and a grouting hole 8 inclined toward the center arranged on the outer side of the second stop slurry plate 5.

[0023] The utility model is used for the reserved hole sealing device of the pier body. During construction, the two tension bolts 7 are first passed through the reserved through holes on the pier body. Then, the two ends of the two tension bolts 7 are respectively passed through the two first grouting plates 2 connected together and the two second grouting plates 5 connected together for fixation, and the grouting inlet of the grouting hole 8 of the second grouting plate 5 is kept at the upper end of the second connecting pipe 6. Then, grouting is carried out from the grouting hole 8 to the through hole. After the grouting is completed, the fixing structure of the first grouting plate 2 and the second grouting plate 5 and the tension bolts 7 are removed. Finally, the tension bolts 7 are pulled out, and the tiny bolt holes caused by the tension bolts 7 are sealed with rigid foam polyurethane or grouting.

[0024] The utility model is used for the pier body reserved hole plugging device, which has a simple structure and flexible installation, and is extremely convenient to install and dismantle during construction. For pier bodies of different sizes, the plugging operation of pier bodies of any size can be satisfied by adjusting the sizes of the first contact plate 1 and the second contact plate 4. Moreover, the device can be used directly after being processed and manufactured, with low cost and easy standardization, and has outstanding results in terms of construction efficiency, safe operation and economic benefits. With the device, only one construction worker and one aerial platform are needed to complete the assembly and grouting plugging work, which can effectively improve the on-site construction efficiency, reduce construction costs, effectively improve material savings and turnover rate, and also improve safety performance.

[0025] As a further improvement of the above technical solution, sealing gaskets (not shown in the figure) are provided on the opposite sides of the first slurry stopping plate 2 and the second slurry stopping plate 5. The sealing gaskets can not only improve the sealing of the connection between the first slurry stopping plate 2, the second slurry stopping plate 5 and the pier body, avoiding leakage due to loose fit, but also protect the surface of the first slurry stopping plate 2 and the second slurry stopping plate 5, avoiding damage caused by collision and scratches of the pier body, thereby extending the service life.

[0026] As a further improvement of the above technical solution, a sleeve 9 is sleeved on the outer side of the tension bolt 7. Figure 4 As shown, in this embodiment, the sleeve 9 is set as a PVC tube. After the reserved perforation holes on the pier body are grouting, the setting of the PVC sleeve 9 prevents the slurry from wrapping the tension bolts 7, thereby facilitating the removal of the tension bolts 7. After the tension bolts 7 are removed, the bolt holes left on the pier body are small and can be sealed with rigid foam polyurethane or grouting. The PVC sleeve 9 can improve the recycling and reuse of the tension bolts 7, which is beneficial to saving materials and improving the turnover rate of the tension bolts 7.

[0027] As a preferred implementation of the above technical solution, the first connection plate 1 and the second connection plate 4 are both provided with a scale for displaying length (not shown in the figure) and an adjustment mechanism for adjusting the length (not shown in the figure), so as to facilitate precise adjustment of the distance between the two first stop slurry plates 2 and the distance between the two second stop slurry plates 5 according to the spacing between the two opposing holes reserved on the pier body. This not only can adapt to the blocking of opposing holes of different widths, but also is suitable for the simultaneous blocking of two opposing holes with low parallelism, which has higher applicability and improved construction efficiency.

[0028] As a preferred implementation of the above technical solution, the adjustment mechanism may specifically be a buckle and slot connection structure or a fastening bolt connection structure.

[0029] In order to facilitate installation and fixation, as a preferred implementation of the above technical solution, the two ends of the tension bolt 7 are respectively fastened and limited with the first stop plate 2 and the second stop plate 5 by two mountain-shaped disc nuts 10.

[0030] As a further improvement of the above technical solution, the first connecting pipe 3 and the second connecting pipe 6 are provided with anti-overflow rings (not shown in the figure), which can effectively prevent slurry leakage and ensure the beautiful surface of the pier body after plugging.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
