Referring to fig. 1, the shock insulation support connecting structure provided by the embodiment of the application comprises an upper support pier 10, a shock insulation support 11 and a lower support pier 12 which are sequentially arranged from top to bottom; the top of the shock insulation support 11 is provided with an upper flange plate 111, the upper flange plate 111 is detachably connected with the upper buttress 10, the bottom of the shock insulation support 11 is provided with a lower flange plate 112, and the lower flange plate 112 is detachably connected with the lower buttress 12; an end plate 13 abutting against the bottom of the upper buttress 10 is arranged above the upper flange plate 111, the end plate 13 is a steel plate, and a concrete grouting layer 14 is arranged between the end plate 13 and the upper flange plate 111.

Illustratively, the upper buttress 10 and the lower buttress 12 are both reinforced concrete structures, and the shock-insulating support 11 is a shock-insulating rubber support. Of course, in other embodiments, the shock insulation support 11 may have other structures, which are not specifically limited herein. The dimensions of the end plate 13 correspond to the dimensions of the bottom of the upper pier 10 so that the end plate 13 completely covers the bottom of the upper pier 10.

The construction process of the shock insulation support connecting structure provided by the embodiment of the application comprises the following steps:

Firstly, constructing a lower buttress 12, placing a shock insulation support 11 on the top of the lower buttress 12 after the construction of the lower buttress 12 is completed, and connecting a lower flange plate 112 at the bottom of the lower buttress 12 with the lower buttress 12 through a detachable structure after the position of the shock insulation support 11 is adjusted; then, the end plate 13 is placed above the upper flange plate 111 on the top of the shock insulation support 11, and after the distance between the end plate 13 and the upper flange plate 111 is adjusted, the end plate 13 and the upper flange plate 111 are connected together; then, a high-strength grouting material is poured between the end plate 13 and the upper flange plate 111 to form a concrete grouting layer 14, and after the strength of the concrete grouting layer 14 reaches the requirement, the upper buttress 10 is constructed on the end plate 13.

When the shock insulation support 11 needs to be replaced in the later period, the auxiliary supporting device is used for supporting the upper support pier 10, then the connecting structure between the shock insulation support 11 and the upper support pier 10 and the lower support pier 12 is released, the concrete grouting layer 14 is removed by using a wire saw, so that the shock insulation support 11 has a moving space in the vertical direction, and then the old shock insulation support 11 can be removed from between the upper support pier 10 and the lower support pier 12; after the old shock insulation support 11 is removed, a new shock insulation support 11 is placed between the upper support pier 10 and the lower support pier 12, an upper flange plate 111 at the top of the shock insulation support 11 is connected with the upper support pier 10, and a lower flange plate 112 at the bottom of the shock insulation support 11 is connected with the lower support pier 12; then, a high-strength grouting material is poured between the end plate 13 and the upper flange plate 111 to form a concrete grouting layer 14, and after the strength of the concrete grouting layer 14 meets the requirement, the auxiliary supporting device is removed to complete the replacement work of the shock insulation support 11.

According to the shock insulation support connecting structure provided by the embodiment of the application, when the shock insulation support 11 is replaced in the later period, the shock insulation support 11 can be easily removed from between the upper support pier 10 and the lower support pier 12 and replaced only by removing the concrete grouting layer 14, and compared with the prior art, the shock insulation support connecting structure has the advantages that the concrete structure of the support piers is prevented from being damaged, the integrity of the upper support pier 10 and the lower support pier 12 is ensured, and the operation and maintenance cost is reduced.

Referring to fig. 1, the end plate 13 is welded to the steel structural member 101 in the upper pier 10. Wherein the steel structural member 101 comprises at least one of a reinforcement cage and a steel column. For example, the steel structural member 101 may be a steel reinforcement cage, a steel column, a steel reinforcement cage, and a steel column. By welding the end plate 13 with the steel structural member 101, not only the connection firmness between the end plate 13 and the upper buttress 10 can be improved, but also the positioning accuracy of the steel structural member 101 can be ensured when the upper buttress 10 is constructed.

The following describes the construction process of the upper buttress 10, taking the steel structural member 101 including a reinforcement cage and a steel column as an example: firstly placing a steel column on an end plate 13, welding the steel column and the end plate 13 together after adjusting the position, then installing a reinforcement cage on the end plate 13, and welding the reinforcement cage and the end plate 13 together, so that the end plate 13 is used as a foot drop point for anchoring reinforcement at the lower end of the reinforcement cage; and then installing the template, pouring concrete in the template after the template is installed, and dismantling the template after the strength of the concrete meets the requirement to finish the construction work of the upper buttress 10. After the construction of the upper buttress 10 is completed, the end plate 13 can serve as a protection layer to protect the lower end of the reinforcement cage, so that the lower end of the reinforcement cage is prevented from being exposed to rust.

The end plate 13 should have a certain strength and rigidity to meet its support requirements during construction of the upper pier 10, and the thickness of the end plate 13 is, for example, greater than or equal to 3cm. The thicker the end plate 13, the higher its rigidity and strength, but the higher its cost. In order to reduce costs as much as possible, the thickness of the end plate 13 is 3-5 cm, in case of meeting the requirements of rigidity and strength.

The thickness of the concrete grouting layer 14 should firstly meet the space requirement in the vertical direction when the shock insulation support 11 is replaced, and at the same time also meet the minimum thickness requirement of the wire saw when cutting, and the thickness of the concrete grouting layer 14 is more than or equal to 3cm. The thicker the concrete grout layer 14, the easier it is to remove the old shock insulation support 11 from between the upper and lower piers 10, 12 after the concrete grout layer 14 is completely removed, but the greater the effort to remove the concrete grout layer 14 and the more grout is poured between the end plate 13 and the upper flange plate 111 after the new shock insulation support 11 is replaced, the higher the operation and maintenance costs. In order to reduce the operation and maintenance costs as much as possible in the case of meeting the construction space requirements, the thickness of the concrete grouting layer 14 is exemplified to be 3 to 5cm. After the construction of the concrete grouting layer 14 is completed, the end plate 13 can be completely covered, so that the end plate 13 is protected by taking the concrete grouting layer 14 as a protection layer, the end plate 13 is prevented from being exposed to rust, and the service life of the end plate 13 is prolonged.

Referring to fig. 2, the upper flange plate 111 is connected to the upper buttress 10 by a first connection structure; the first connection structure includes a first anchor rod 15 and a first bolt 16; the first anchor rod 15 is vertically arranged in the upper buttress 10, and the first bolt 16 sequentially passes through the upper flange plate 111, the concrete grouting layer 14 and the end plate 13 from bottom to top and then is in threaded connection with the first anchor rod 15.
