Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to an assembled temporary road structure. Background Art

[0002] Temporary construction roads at construction sites generally use cast-in-place concrete pavement structures to achieve site hardening, meet on-site traffic needs and prevent dust. However, cast-in-place cement concrete pavement structures have a technical interval (maintenance cycle) that affects the progress of the project. On the other hand, most of the hardened sites at the construction site need to be demolished after the construction is completed, resulting in a waste of resources and a large amount of construction waste. In addition, existing prefabricated temporary road structure technologies are generally inconvenient to install and do not consider technical issues such as expansion and contraction deformation between panels.

[0003] In the prior art, the patent with publication number CN 219862174 U discloses a prefabricated concrete temporary road, including a frame and a connecting strip; the frame: a concrete pavement is provided at the upper end thereof, and a steel mesh is provided inside the concrete pavement; the connecting strip: a card slot is symmetrically provided on the upper surface thereof, and an assembly slot is symmetrically provided on the left and right sides of the frame, and a convex strip matching the card slot is provided at the upper end of the opening of the assembly slot, and a connecting mechanism matching the assembly slot is uniformly provided inside the connecting strip, and the connecting mechanism includes a rotating sleeve, a T-bar and a pad, and the rotating sleeve is uniformly rotated and connected to the corresponding step hole inside the connecting strip, and a pad is provided at the lower end of the rotating sleeve, and a T-bar is slidably connected inside the rotating sleeve, and the prefabricated concrete temporary road is convenient for rapid assembly and laying of the concrete pavement inside the frame. However, this kind of road structure is inconvenient to install, and the deformation constraint of the connection method is large, which is easy to cause structural cracking.

[0004] In view of this, it is necessary to design an assembled temporary road structure to solve the above problems. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An assembled temporary road structure, comprising:

[0008] Prefabricated blocks, a plurality of prefabricated blocks are arranged and paved in sequence to form an assembly layer of the overall road structure, wherein one end of the prefabricated block is provided with a first protrusion, and the other end is provided with a second protrusion matching the first protrusion;

[0009] First vertical through holes, a plurality of first vertical through holes are arranged on the first protrusion;

[0010] A second vertical through hole, wherein a plurality of second vertical through holes are arranged on the second protrusion corresponding to the first vertical through hole, so that when the first vertical through hole of the prefabricated block and the second vertical through hole of another adjacent prefabricated block are aligned in the vertical direction, an expansion joint obliquely downward is formed between the two prefabricated blocks;

[0011] A fixing member, which is used to be inserted into the corresponding first vertical through hole and second vertical through hole, so that two adjacent prefabricated blocks remain relatively fixed; the first vertical through hole, the second vertical through hole and the fixing member also serve together as a limiting member to keep the sizes of all expansion joints on the road structure consistent;

[0012] The sand and gravel filling area is arranged at the expansion joint to connect two adjacent prefabricated blocks.

[0014] As a further improvement of the present invention, the first protrusion is located at the lower part of one end of the prefabricated block, and is in a structure obliquely downward away from the prefabricated block. The second protrusion is located at the upper part of the other end of the prefabricated block, and is in a structure obliquely upward away from the prefabricated block, so that an overall obliquely downward special-shaped expansion joint is formed between two adjacent prefabricated blocks, and the special-shaped expansion joint includes a first vertical section, an inclined section and a second vertical section that are connected in sequence along the vertical downward direction.

[0015] As a further improvement of the present invention, a plurality of lifting rings are provided on the top surface of the prefabricated block, and the top surface of the lifting rings is lower than the top surface of the prefabricated block.

[0022] 2. The utility model adopts the cooperation of the fixing parts and the protruding parts to complete the connection of the prefabricated blocks and the setting of the reserved expansion joints. Compared with the existing method of connecting adjacent prefabricated blocks by using a snap-fit ​​setting, it can avoid the damage of the connection part caused by the collision of the two prefabricated blocks during the installation process.

[0023] 3. The arrangement of the first vertical through hole and the second vertical through hole of the utility model can ensure the consistency of the size of the expansion joints on the road, and at the same time, the gravel layer filled in the expansion joints can also play a certain fixing role for the adjacent prefabricated blocks.

[0024] 4. The road structure of the utility model is easy to install and can also avoid cracking and sudden changes of prefabricated blocks caused by improper deformation. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] See also Figure 1-Figure 3 As shown, the utility model provides an assembled temporary road structure, comprising:

[0034] Prefabricated blocks 11, a plurality of prefabricated blocks 11 are arranged and paved in sequence to form an assembly layer 10 of an overall road structure, wherein one end of the prefabricated block 11 is provided with a first protrusion 111, and the other end is provided with a second protrusion 112 matching the first protrusion 111;

[0035] First vertical through holes 21, a plurality of first vertical through holes 21 are arranged on the first protrusion 111;

[0036] Second vertical through holes 22, a plurality of second vertical through holes 22 are arranged on the second protrusion 112 corresponding to the first vertical through holes 21, so that when the first vertical through hole 21 of the prefabricated block 11 and the second vertical through hole 22 of another adjacent prefabricated block 11 are aligned in the vertical direction, an expansion joint 30 obliquely downward is formed between the two prefabricated blocks 11;

[0037] The fixing member 23 is used to be inserted into the corresponding first vertical through hole 21 and the second vertical through hole 22, so that two adjacent prefabricated blocks 11 remain relatively fixed; the first vertical through hole 21, the second vertical through hole 22 and the fixing member 23 also serve together as a limiting member to keep the sizes of all expansion joints 30 on the road structure consistent;

[0038] The sand and gravel filling area is arranged at the expansion joint 30 to connect two adjacent prefabricated blocks 11 .

[0039] Specifically, the first vertical through hole 21 is arranged on the first protrusion 111 at a position 1 / 3-2 / 3 away from the first protrusion 111 at one end of the prefabricated block 11, and the second vertical through hole 22 is arranged on the second protrusion 112 at a position 1 / 3-2 / 3 away from the second protrusion 112 at one end of the prefabricated block 11; preferably, the first vertical through hole 21 is arranged on the first protrusion 111 at a position 1 / 2 away from the first protrusion 111 at one end of the prefabricated block 11, and the second vertical through hole 22 is arranged on the second protrusion 112 at a position 1 / 2 away from the second protrusion 112 at one end of the prefabricated block 11, so that the periphery of the vertical through hole has a thicker structure to ensure the stability of the vertical through hole. In this embodiment, two first vertical through holes 21 are provided, and the two first vertical through holes 21 are spaced apart on the first protrusion 111; two second vertical through holes 22 are provided, and the two second vertical through holes 22 are spaced apart on the second protrusion 112, so that vertical through holes are distributed at the four corners of the prefabricated block 11.

[0040] Specifically, in this embodiment, the first protrusion 111 is located at the lower part of one end of the prefabricated block 11, and is in a structure that is obliquely downward away from the prefabricated block 11, and the second protrusion 112 is located at the upper part of the other end of the prefabricated block 11, and is in a structure that is obliquely upward away from the prefabricated block 11, so that an overall obliquely downward special-shaped expansion joint 30 is formed between two adjacent prefabricated blocks 11, and the special-shaped expansion joint 30 includes a first vertical section 31, an inclined section 32, and a second vertical section 33 that are sequentially connected along the vertical downward direction. By setting the expansion joint 30 as an overall obliquely downward structure, it is beneficial to facilitate the flow of sand and gravel when pouring sand and gravel into the expansion joint 30 to form a sand and gravel filling area, thereby quickly completing the sand filling process of the expansion joint 30, so that the sand and gravel filling area has a certain density.

[0041] like Figure 3 As shown, in other embodiments, the vertices of the first protrusion 111 and the second protrusion 112 can be in the same plane as the top surface of the prefabricated block 11, and the bottom points of the first protrusion 111 and the second protrusion 112 can be in the same plane as the bottom surface of the prefabricated block 11. The first protrusion 111 is set to an oblique downward structure away from the prefabricated block 11, and the second protrusion 112 is set to an oblique upward structure away from the prefabricated block 11, so that an oblique expansion joint 30 is formed between adjacent prefabricated blocks 11.

[0042] Specifically, a plurality of lifting rings 40 are provided on the top surface of the prefabricated block 11, and the top surface of the lifting ring 40 is lower than the top surface of the prefabricated block 11, so that the lifting ring 40 is built into the top of the prefabricated block 11.

A cap for protecting the lifting ring 40 is also provided at the position corresponding to the lifting ring 40 on the prefabricated block 11, and the lifting ring 40 is made of stainless steel anti-corrosion material.

[0043] Specifically, angle steels are embedded in the corner surfaces of the prefabricated blocks 11 to protect the edges and corners from damage.

In addition, a crushed stone reinforcement layer 60 may be provided below the gravel layer 50, so that when the rebound modulus of the roadbed is less than 20 MPa, the crushed stone reinforcement layer 60 can be used to strengthen the roadbed.

[0045] Specifically, in this embodiment, the fixing member 23 is round steel.

[0046] Specifically, during installation, firstly, the crushed stone reinforcement layer 60 and the sand and gravel layer 50 are laid according to the site conditions, and then the prefabricated block 11 is hoisted to the installation position by using a crane device, and then the adjacent prefabricated blocks 11 are hoisted in sequence along a certain direction, and the positions of the adjacent prefabricated blocks 11 are adjusted so that the first vertical through holes 21 of the two prefabricated blocks 11 are aligned with the second vertical through holes 22, and the fixing members 23 are inserted into the corresponding first vertical through holes 21 and second vertical through holes 22, so that the adjacent prefabricated blocks 11 remain in a relatively fixed state; after the adjacent prefabricated blocks 11 are fixed by using the cooperation of the vertical through holes and the fixing members 23, the sizes of the expansion joints 30 between all adjacent prefabricated blocks 11 on the road structure can be kept consistent, and there is no need to use other tools to adjust the size of the expansion joints 30, which can avoid the problem that the expansion joints 30 on the road structure are inconsistent in size due to installation, which makes the deformation that some parts of the road can withstand smaller, so that the parts are easily damaged in daily use and need to be repeatedly repaired;

[0047] The expansion joint 30 is filled with sand and gravel to be dense, and the transverse joints, longitudinal joints and connecting parts of the road structure with surrounding structures are filled with sand to be dense, and the installation of the road structure is completed.

[0048] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
