Description

Technical Field

[0001] The present application relates to the technical field of bridge construction, and in particular to a construction structure of a bubble-mixed lightweight soil retaining wall and a construction method thereof. Background Art

[0002] With the large-scale development of my country's transportation network, the construction of large bridges in mountainous areas has also appeared frequently. The main towers used to support the bridges are inevitably built in mountainous areas. Therefore, it is necessary to build a main tower construction platform on the high slopes in the mountainous areas to support the main towers. During the construction of the main tower construction platform on the high slope, bubble mixed lightweight soil retaining walls are usually used to support the main tower construction platform.

[0003] In the related art, the bubble-mixed lightweight soil retaining wall mainly includes a foundation pit excavated on a high slope, a foundation cushion layer laid on the bottom side of the foundation pit, a retaining wall arranged on a fixed foundation cushion layer, and fixed columns arranged in the retaining wall. An installation groove for installing the retaining wall is provided at the edge of the foundation cushion layer. There are several fixed columns, which are arranged along the circumferential direction of the retaining wall, and the several fixed columns are all located on the inner side of the retaining wall. The retaining wall is formed by several prefabricated panels spliced ​​together by cement mortar, and several prefabricated panels are provided with embedded bars, and the fixed columns are provided with tie rods for fixed connection with the embedded bars. During construction, a complete retaining wall is formed by applying mortar to the edges of several prefabricated panels and fixing the tie rods with the embedded bars. At this time, the bubble-mixed lightweight soil is poured into the foundation pit to form a construction platform for the main tower of the bridge.

[0004] However, since the design height of the retaining wall in the bubble mixed lightweight soil retaining wall in the related technology is usually high, it is necessary to set up scaffolding that matches the design height of the retaining wall when splicing and installing several prefabricated panels, which is time-consuming and labor-intensive, increases construction costs, and affects construction progress. At the same time, when splicing the prefabricated panels, the construction workers need to apply mortar on the edges of each prefabricated panel and then splice and install them, which is labor-intensive and has low work efficiency. Summary of the invention

[0005] In order to improve the problem in the related art that during the construction of a bubble mixed lightweight soil retaining wall, due to the high design height of the retaining wall, when splicing and installing several prefabricated panels, it is necessary to set up scaffolding matching the design height of the retaining wall, which is time-consuming and labor-intensive, increases the construction cost, affects the construction progress, and at the same time, the construction workers have low work efficiency when splicing the prefabricated panels. The first purpose of this application is to provide a construction structure for a bubble mixed lightweight soil retaining wall.

[0006] The construction structure of a bubble mixed lightweight soil retaining wall provided in this application adopts the following technical solution:

[0007] A construction structure of a bubble mixed lightweight soil retaining wall, comprising a fixed frame arranged in a foundation pit, and the fixed frame is located outside a fixed column, the fixed frame is slidably connected to a first sliding seat, the first sliding seat can slide relative to the fixed frame along the length direction of the fixed frame, the first sliding seat is slidably arranged on a second sliding seat, the second sliding seat can move relative to the first sliding seat toward or away from the fixed column, the second sliding seat is liftably arranged on a bearing seat, the bearing seat is rotatably arranged with a working platform, one side of the working platform extends out of the bearing seat in a direction away from the fixed column, and the The working platform can be flipped from a horizontal state to a vertical state relative to the bearing seat. A prefabricated panel is arranged on the working platform. The length of the prefabricated panel matches the design height of the retaining wall. The prefabricated panel extends out of the working platform from the side of the working platform close to the fixed column. A flipping component for driving the working platform to flip is arranged on the bearing seat. A movable frame is slidably arranged on the working platform. The movable frame is liftable and provided with a clamping plate for clamping the prefabricated panel. A clamping component is arranged on the movable frame for driving the clamping plate to rise and fall relative to the working platform so that the clamping plate cooperates with the working platform to clamp the prefabricated panel.

[0008] By adopting the above technical scheme, during construction, by hoisting the fixed frame into the foundation pit, and making the installation groove between the fixed frame and the fixed column, a number of prefabricated panels that match the design height of the retaining wall are made on site according to the design height and design length of the retaining wall, at this time, the prefabricated panel is transported to the working platform, and the installation groove is filled with mortar, and the clamping plate is driven to move by driving the moving frame so that the clamping plate is located directly above the prefabricated panel, and the clamping assembly drives the clamping plate to descend, so that the clamping plate cooperates with the working platform to clamp the prefabricated panel. At this time, the working platform is driven to flip relative to the bearing seat by the flipping assembly, and the working platform is flipped to a vertical state abutting against the bearing seat, that is, the prefabricated panel is flipped to a vertical state, and the position of the prefabricated panel is adjusted by driving the first sliding seat and the second sliding seat to slide relative to the fixed frame, so that the bottom side of the prefabricated panel is located directly above the installation groove, and at this time, the bearing seat is driven to rise and fall vertically relative to the second sliding seat, so that the bottom side of the prefabricated panel is inserted into the installation groove, and the installation of a prefabricated panel is realized, and this is repeated until several prefabricated panels are spliced ​​in sequence, thereby completing the construction of the retaining wall. Compared with the bubble mixed lightweight soil retaining wall in the related art, the present application prefabricates on-site prefabricated panels that match the design height of the retaining wall, and places the prefabricated panels flat on the work platform. The mobile frame is driven to slide relative to the work platform so that the clamp is located directly above the prefabricated panel.

The entire construction process does not require the erection of scaffolding, which reduces the construction cost and speeds up the construction progress.
