Description

Technical Field

[0001] The utility model relates to the technical field of airport pavement maintenance, in particular to a fast plate-changing structure for an airport pavement. Background Art

[0002] The pavements of most airports in my country are mainly made of concrete. Due to factors such as the age, intensity of use and environment of the pavement, a few slabs will suffer structural damage such as broken slabs and misaligned slabs, which will reduce the bearing capacity of the slabs and bring safety hazards to the passage and take-off and landing of aircraft. The entire pavement needs to be replaced.

[0003] Especially in the throat of the airport taxiway, once this area is not airworthy, it will have a serious impact on the airport operation. Rapid plate replacement is the best solution to this problem. In the process of rapid plate replacement, how to finely adjust the large-format and heavy concrete precast slabs in the pit foundation to the same height as the adjacent pavement has always been a construction problem in this field. It takes a lot of time and seriously affects the time required for plate replacement.

[0004] At present, there is a lack of mature experience in the domestic construction of rapid replacement of the entire concrete pavement without stopping the navigation. The usual practice is to use lifting equipment to lift the concrete precast slab and put it into the foundation pit to be repaired, and use the lifting equipment to level the concrete precast slab. However, the operating accuracy of the lifting equipment is insufficient, and the leveling needs to rely on the experience and technical proficiency of the workers, and it is difficult to control the time required for leveling. How to quickly level the concrete precast slab during the rapid replacement process is an urgent problem to be solved by technicians in this field.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present application, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0006] The utility model aims to provide a rapid plate-changing structure for an airport pavement, so as to solve the technical problem in the prior art that the concrete prefabricated plates can only be leveled by relying on the workers' experience.

[0007] In order to solve the above technical problems, the utility model provides a rapid plate changing structure for an airport pavement, the rapid plate changing structure comprising: a plurality of height-adjustable pillars are embedded in a foundation pit, concrete precast slabs are laid on the pillars, wherein the height of the top surface of the adjusted pillars from the airport pavement matches the thickness of the concrete precast slabs, so that the surface of the laid concrete precast slabs is flush with the airport pavement.

[0008] Furthermore, four pillars are provided, and the pillars are distributed at four corners of the precast concrete slab.

[0009] Furthermore, the pillar includes: a column body, and a tray is arranged on the top of the column body.

[0010] Furthermore, the column is cylindrical.

[0011] Furthermore, the bottom of the pillar is provided with a chamfered surface.

[0012] The advantages of adopting the above technical solution are:

[0013] By applying pressure to the pillars, the bottom of the pillars are embedded in the foundation pit. By adjusting the length of the pillars exposed in the foundation pit, the height of the top surface of the pillars from the airport pavement is adjusted to match the thickness of the precast concrete slabs. After the precast concrete slabs are placed in the foundation pit, the precast concrete slabs are pressed onto the pillars to make the surface of the precast concrete slabs flush with the surrounding airport pavement.

[0014] Compared with the traditional direct adjustment of heavy concrete precast panels, the operation of adjusting the height of the pillars in this application is less difficult, does not need to rely on the experience of workers, takes less construction time, and has low material costs.

[0027] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0028] like Figure 1 The figure shows a specific embodiment of a quick plate-changing structure for an airport pavement of the present application. In this embodiment, after the damaged pavement is cut and removed, a foundation pit is left. The quick plate-changing structure specifically includes: four height-adjustable pillars 2 are embedded in the foundation pit, and the pillars 2 are distributed at the four corners of the concrete precast slab 1. The concrete precast slab 1 is laid on the pillars 2, so that the top surface of the pillars 2 is attached to the airport pavement 3, and the pillars 2 are supported under the concrete precast slab 1.

[0029] like Figure 2 As shown, the height of the top surface of the pillar 2 from the airport pavement 3 after adjustment matches the thickness of the precast concrete slab 1 , so that the surface of the precast concrete slab 1 after laying is flush with the airport pavement 3 .

[0030] There are many ways to adjust the support 2, for example, the support 2 is an existing telescopic rod, or as in the present application, Figure 2 The pillar 2 is a cylindrical structure, and the pillar 2 is embedded in the foundation pit by cutting grooves on the foundation pit and then using methods such as knocking and squeezing.

[0031] like Figure 3 As shown, the pillar 2 includes: a column 21, which is a cylindrical structure, and a tray 22 is arranged on the top of the column 21.

[0032] like Figure 4 As shown, the support column 2 includes: a column body 21, a chamfered surface 23 is arranged at the bottom of the column body 21, and a tray 22 is arranged at the top of the column body 21. The tray 22 increases the contact area between the support column 2 and the concrete precast panel 1, thereby improving the support stability.

[0033] like Figure 5 As shown, the pillar 2 comprises: a column 21, and a chamfered surface 23 is provided at the bottom of the column 21. The chamfered surface 23 facilitates the pillar 2 to be embedded in the foundation pit.

[0034] like Figure 6 As shown, the pillars 2 are distributed near the four corners of the precast concrete slab 1 , and the pillars 2 are only used to support the precast concrete slab 1 .

[0035] By applying pressure to the pillar 2, the bottom of the pillar 2 is embedded in the foundation pit, and by adjusting the length of the pillar 2 exposed in the foundation pit, the height of the top surface of the pillar 2 from the airport pavement 3 is adjusted to match the thickness of the precast concrete slab 1. After the precast concrete slab 1 is placed in the foundation pit, the precast concrete slab 1 is pressed onto the pillar 2 so that the surface of the precast concrete slab 1 is flush with the surrounding airport pavement 3.

[0036] Compared with the traditional method of directly adjusting the heavy concrete precast slab, this embodiment adjusts the height of multiple pillars 2, which has low operation difficulty, does not need to rely on the experience of workers, takes less construction time, and has low material costs.

[0037] 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 aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
