[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In existing technology, a hole is pre-drilled at the position of the inner stop block of the pier pad stone with a steel tenon structure. Most of the area of ​​this hole is located on the support surface at the bottom of the rear outrigger, causing the rear outrigger of the WE-SC900H transport and erection machine to be unable to provide stable support. To solve the above problem, the following technical solution is provided; please refer to [link / reference]. Figure 1-4 ;

[0025] In the construction of the steel tenon structure earthquake-resistant drop beam bridge pier, a steel tenon structure reserved hole 7 is reserved on the inner side of the pier pad stone 9. The diameter of the steel tenon structure reserved hole 7 is 40cm and the height is 40cm.

[0026] The support 1 is located in the pre-reserved hole 7 of the steel tenon structure. The support 1 is a cylindrical structure and includes a lower support 11 and an upper support 12. The lower support 11 and the upper support 12 can be made of Q345B high-strength steel or cast with reinforced concrete.

[0027] The lower support 11 has an installation groove 2 in the middle for accommodating the upper support 12, and the lower support 11 and the upper support 12 form a nested cylindrical tube.

[0028] The diameter of the lower support pier 11 is 28cm and the height is 40cm.

[0029] The upper support 12 has an external thread 3 on its side wall, and the inner side wall of the mounting groove 2 has an internal thread 4 that matches the external thread 3. The upper support 12 is threadedly connected to the lower support 11. The height can be adjusted by the cooperation of the external thread 3 and the internal thread 4. The height range is 30-50cm, which can be adapted to the pre-reserved holes 7 of steel tenon structure of different depths.

[0030] The bottom of the lower support pier 11 is provided with an extension structure, specifically a hydraulic support claw 8 that can extend outward. There are three hydraulic support claws 8 in total, and the included angle between adjacent hydraulic support claws 8 is 120° to ensure uniform force distribution.

[0031] The output end of the hydraulic support claw 8 extends through the lower support 11. A support plate 5 is installed on the outer end of the hydraulic support claw 8. The hydraulic support claw 8 abuts against the inner wall of the pre-reserved hole 7 of the steel tenon structure through the support plate 5. After the hydraulic support claw 8 is extended by hydraulic drive, the support plate 5 fits tightly against the inner wall of the pre-reserved hole 7 of the steel tenon structure, enhancing the resistance to lateral displacement.

[0032] The upper part of the upper support pier 12 is provided with a wedge-shaped steel plate 6, and the top of the wedge-shaped steel plate 6 is provided with an anti-slip surface 61 to prevent the rear support leg from sliding on the wedge-shaped steel plate 6.

[0033] Multiple sets of prefabricated wedge-shaped steel plates 6 with different inclination angles are used, i.e., the anti-slip surface 61 is inclined. The top surface of the upper support 12 is quickly leveled by combination and matching, and the error is controlled within ±1mm.

[0034] The wedge-shaped steel plate 6 is made of Q235B steel plate with a thickness of 15mm. The inclination angle of a single set of wedge plates is 1°, 2°, 3° or above, and its diameter matches the diameter of the top surface of the upper support 12. Based on the height deviation of the top surface of the upper support 12, wedge-shaped steel plates 6 with matching inclination angles are selected for combination. The flatness of the top surface is checked by a level, and the orientation of the wedge-shaped steel plate 6 is finely adjusted by rotating it before installation.

[0035] A positioning post 62 is provided at the center of the bottom of the wedge-shaped steel plate 6. The positioning post 62 is compatible with the positioning hole 13 at the center of the upper support 12. During installation, the positioning post 62 is first aligned with the positioning hole 13 for installation, which makes it easy to quickly find the installation point of the wedge-shaped steel plate 6.

[0036] The positioning hole 13 is longitudinally continuous. If necessary, sand and gravel can be injected into the bottom gap of the mounting groove 2 through the positioning hole 13 to enhance the bearing capacity of the lower support 11 and the upper support 12.

[0037] The top surface of the upper support 12 is provided with limiting square holes 14 arranged along the edge, with no less than 30 limiting square holes 14. Several limiting blocks 63 that match the limiting square holes 14 are fixed on the bottom surface of the wedge-shaped steel plate 6. After rotating the wedge-shaped steel plate 6 to finely adjust to a suitable orientation, the limiting blocks 63 are aligned with the limiting square holes 14 below them and inserted to fix the orientation of the wedge-shaped steel plate 6 and prevent orientation deviation during the load-bearing process.

[0038] Two clamps can be installed on the outer wall of the lower support pier 11 as handles.

[0039] Working principle: The lower support 11 is vertically placed into the pre-reserved hole 7 of the steel tenon structure, ensuring that the bottom of the lower support 11 is in contact with the bottom surface of the pre-reserved hole 7 of the steel tenon structure; the hydraulic support claw 8 is activated to drive the support plate 5 to unfold and fit tightly against the inner wall of the pre-reserved hole 7 of the steel tenon structure, and a polyurethane anti-slip coating is sprayed to enhance friction.

[0040] Screw the upper support 12 into the mounting groove 2 of the lower support 11 and adjust the total height by rotating the thread. Use a level to check the top surface of the upper support 12 to ensure that it is flush with the concrete surface of the bridge pier. If the top surface of the upper support 12 is tilted, select a wedge steel plate 6 with a matching tilt angle according to its height deviation. Insert the positioning post 62 at the bottom of the wedge steel plate 6 into the positioning hole 13 in the center of the upper support 12. After adjusting the tilt direction, insert the limiting block 63 into the limiting square hole 14 for limiting. After completion, use a level to check the levelness again (error ≤ ±1mm).

[0041] Epoxy resin mortar or gravel is poured into the gap between the lower support 11 and the reserved hole 7 of the steel tenon structure to fill the gap until it is dense. Let it stand for 30 minutes to allow the mortar to cure and form an integral load-bearing structure.

[0042] Apply 1.3 times the design load to the overall load-bearing structure for 20 minutes and check for settlement, displacement or structural deformation. If the upper support pier 12 has no settlement, the hydraulic support claw 8 is not loose and the wedge steel plate 6 does not slip, then the standard is met.
