Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction access road technology, and in particular to a recyclable prefabricated construction access road. Background Technology
[0002] In engineering construction, temporary access roads are often constructed before construction begins to ensure unobstructed access. Common methods for constructing temporary access roads include cast-in-place concrete or steel plate paving. Cast-in-place concrete requires mixing and transporting the concrete to the construction site for pouring, resulting in high material costs, inconvenient construction, and high labor costs due to the need for subsequent curing until the concrete reaches sufficient strength. Furthermore, cast-in-place concrete temporary access roads cannot be reused, and their subsequent demolition generates substantial construction waste, posing significant environmental problems. Utility Model Content

[0022] 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.
[0023] The purpose of this invention is to provide a recyclable prefabricated construction access road to solve the problems existing in the prior art.
[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] The recyclable prefabricated construction access road in this embodiment, such as Figures 1-4 As shown, it includes a main concrete slab 1 and side concrete slabs 2. The side concrete slabs 2 are set on the outer perimeter of the sidewalk to form the sidewalk frame. The main concrete slabs 1 are set inside the sidewalk frame formed by the side concrete slabs 2 and there is at least one row of them. The top surfaces of the main concrete slabs 1 and the side concrete slabs 2 are provided with splicing grooves 3 and splicing protrusions 4. Adjacent side concrete slabs 2, adjacent main concrete slabs 1 and side concrete slabs, and adjacent main concrete slabs 1 are spliced together by splicing grooves 3 and splicing protrusions 4.
[0026] In this specific embodiment, it also includes hoisting embedded parts 5, which are embedded in the main concrete slab 1 and the side concrete slab 2, and the top of the hoisting embedded parts 5 is exposed above the top of the main concrete slab 1 and the side concrete slab 2; each main concrete slab 1 and side concrete slab 2 is provided with 4 hoisting embedded parts 5, which are distributed in a rectangular shape, and 4 hoisting embedded parts 5 are provided on the top of each concrete slab, so that the slab can be kept stable during hoisting and will not tilt.
[0027] In this specific embodiment, the hoisting embedded part 5 includes steel bars and shear nails welded together vertically. The main body of the steel bars and shear nails is embedded in the main concrete slab 1 or the side concrete slab 2. The top of the main concrete slab 1 and the side concrete slab 2 are provided with hoisting grooves. The top nail head of the shear nail is exposed in the hoisting groove. The hoisting groove ensures that the protruding part of the shear nail will not protrude from the top of the concrete slab and will not affect the flatness of the road surface.
[0028] In this specific embodiment, a centrally embedded water-stop deformable rubber sheet 6 is also included. The centrally embedded water-stop deformable rubber sheet 6 is located within the interlayer between the main concrete slab 1 and the edge concrete slab 2. The periphery of the centrally embedded water-stop deformable rubber sheet 6 protrudes from the sidewalls of the main concrete slab 1 and the edge concrete slab 2, forming a rubber sealing strip structure. During pavement assembly, the centrally embedded rubber water-stop sealing sheet 6 is installed at the joints of adjacent main concrete slabs 1. The centrally embedded rubber water-stop sealing sheet 6 is pre-embedded in the center of the concrete slab during precasting. The protruding rubber sealing strip forms a seal between the concrete slabs, preventing rainwater erosion and allowing for deformation. This prevents rainwater from eroding the slab joints during heavy rains and avoids slab edge settlement affecting construction vehicle traffic. It also allows for thermal expansion and contraction deformation of the main concrete slab 1, preventing the main concrete slab 1 from arching or becoming detached due to deformation.
[0029] In this specific embodiment, both the main concrete slab 1 and the side concrete slab 2 are rectangular slabs. The top surface of the splicing protrusion 4 is flush with the top surface of the main concrete slab 1 or the side concrete slab 2, and the bottom surface of the splicing protrusion 4 is flush with the middle of the main concrete slab 1 or the side concrete slab 2 (i.e., the thickness of the splicing protrusion 4 is half the thickness of the concrete slab). The top surface of the splicing groove 3 is flush with the middle of the main concrete slab 1 or the side concrete slab 2, and the bottom surface of the splicing groove 3 is flush with the bottom surface of the main concrete slab 1 or the side concrete slab 2 (i.e., the thickness of the splicing groove 3 is half the thickness of the concrete slab). The splicing groove 3 is a trapezoidal groove, and the splicing protrusion 4 is a trapezoidal block. The groove and the protrusion are compatible and spliced together. The purpose of setting the splicing groove 3 is to combine with the fixed splicing protrusion 4 to ensure that the settlement of adjacent main concrete slabs 1 is consistent, preventing large settlement differences between adjacent main concrete slabs due to inconsistent foundation bearing capacity, which would affect the movement of construction vehicles. The function of the splicing protrusion 4 is to combine with the fixed splicing groove 3 to prevent large horizontal relative displacement of adjacent main concrete slabs 1, and to prevent large gaps from being generated between adjacent main concrete slabs due to the horizontal relative displacement of the main concrete slabs 1, which would affect the movement of construction vehicles.
[0030] In this specific embodiment, a splicing protrusion 4 is provided on the front side of the top surface of the main concrete slab 1, a splicing groove 3 is provided on the rear side of the top surface of the main concrete slab 1, a splicing protrusion 4 is provided on the left side of the top surface of the main concrete slab 1, and a splicing groove 3 is provided on the right side of the top surface of the main concrete slab 1; a splicing protrusion 4 is provided on the front side of the top surface of the side concrete slab 2, a splicing groove 3 is provided on the rear side of the top surface of the side concrete slab 2, a splicing groove 3 is provided on the right side of the top surface of the side concrete slab 2 located on the left side of the main concrete slab 1, and a splicing protrusion 4 is provided on the left side of the top surface of the side concrete slab 2 located on the right side of the main concrete slab 1.
[0031] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
