Description
Technical Field
The utility model relates to the field of tunnel construction materials, in particular to a tunnel asphalt pavement auxiliary construction steel plate.
Background
With the rapid development of asphalt pavement construction technology, more and more tunnel pavements are constructed by adopting asphalt concrete, however, two inspection wells are respectively arranged in the tunnel every 50 meters. At present, the well lid on the inspection shaft mainly adopts precast concrete apron, covers the well lid again after bituminous paving construction accomplishes. The existing construction method is that when the tunnel asphalt is constructed, a wooden template is used for covering an inspection wellhead, the asphalt around the wellhead is chiseled after the asphalt pavement construction is finished, and then a cover plate is installed. However, the adopted wood template has poor stability, and the construction process is easy to push and damage, so that a large amount of asphalt mixture falls off from the inspection well; in addition, before the inspection well cover is installed, a large amount of manpower and material resources are consumed for cleaning, and asphalt edges around the well mouth are crushed due to rolling of the rubber-tyred roller to form an inclined plane; in addition, during installation, the cover plates are different in size and have height difference, and great hidden danger is caused to driving safety after installation is completed.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, the present invention aims to provide an auxiliary construction steel plate for tunnel asphalt pavement, which facilitates the construction and modular installation of the pavement and saves labor cost.
In order to achieve the purpose, the utility model provides an auxiliary construction steel plate for a tunnel asphalt pavement, which comprises a steel frame arranged on an inspection well in a tunnel hole, and an iron cover plate which is embedded into the inner side of the steel frame and covers the inspection well, wherein the steel frame is arranged on the inspection well. The steel frame is greater than or equal to the well mouth of the inspection well, and the area of the iron cover plate corresponds to the area of the inner side of the steel frame. Fixing plates extending outwards are respectively arranged on two sides of the steel frame; the fixed plate is provided with a fixed hole, and the fixed hole is provided with a screw which penetrates through the fixed hole to fix the fixed plate on the inspection well.
In some embodiments, the steel frame is a box iron frame.
In some embodiments, a supporting block for supporting the iron cover plate is arranged on the inner side of the steel frame.
In some embodiments, the steel frame has a dimension of 70cm x 40cm or 70cm x 65 cm.
In some embodiments, the iron cover plate is provided with a handle hole.
The utility model has the advantages of convenient construction and modular installation of the road surface and labor cost saving. During specific application, before the construction of a middle surface layer (5.5cm) of tunnel asphalt, the steel frame is fixedly installed at an inspection well mouth, an iron cover plate is placed on the steel frame during construction, and the iron plate is taken out after the rolling of the middle surface layer is completed. Before the construction of the upper surface layer (4.5cm), the iron cover plate is installed in the steel frame, the iron cover plate is taken out after the rolling is finished, and finally the uniform prefabricated cement cover plate for the inspection well is installed. So not only can guarantee that the pitch work progress can not drop to cause the later stage to produce a large amount of cleaning work in the inspection shaft, also avoided the well head all around pitch limit portion simultaneously because of rolling of rubber tyer road roller collapse the limit and form the inclined plane, with the apron formation not of uniform size the difference in height's the condition, ensure the roughness on whole driving road surface. The inspection well is polluted by a large amount of mixtures during tunnel asphalt pavement construction to the greatest extent, the flatness around the inspection well is improved, and the construction problem of smooth running surface is ensured. The construction and the modularization installation of the road surface of being convenient for have been realized, and the effect of saving the cost of labor.

Detailed Description
The following describes the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1-3, an auxiliary construction steel plate for a tunnel asphalt pavement comprises a steel frame 1 arranged on an inspection well in a tunnel, and an iron cover plate 2 embedded into the inner side of the steel frame 1 and covering the inspection well and arranged on the steel frame 1. The steel frame 1 is larger than or equal to the well mouth of the inspection well, and the area of the iron cover plate 2 corresponds to the area of the inner side of the steel frame 1. Fixing plates 3 extending outwards are respectively arranged on two sides of the steel frame 1; the fixing plate 3 is provided with a fixing hole 4, and the fixing hole 4 is provided with a screw which penetrates through the fixing hole 4 and fixes the fixing plate 3 on the inspection well. The steel frame 1 is a square iron frame. The inner side of the steel frame 1 is provided with a supporting block 5 for supporting the iron cover plate 2. The steel frame 1 has dimensions of 70cm x 40cm or 70cm x 65 cm. The iron cover plate 2 is provided with a handle hole 6.
During application, before the construction of a middle surface layer (5.5cm) of tunnel asphalt, the steel frame 1 is fixedly installed at an inspection well mouth, an iron cover plate 2 is placed on the steel frame 1 during construction, and the iron plate is taken out after the rolling of the middle surface layer is completed. Before the construction of an upper surface layer (4.5cm), the iron cover plate 2 is installed in the steel frame 1, the iron cover plate 2 is taken out after the rolling is finished, and finally, the uniform prefabricated inspection well cement cover plate is installed. So not only can guarantee that the pitch work progress can not drop to cause the later stage to produce a large amount of cleaning work in the inspection shaft, also avoided the well head all around pitch limit portion simultaneously because of rolling of rubber tyer road roller collapse the limit and form the inclined plane, with the apron formation not of uniform size the difference in height's the condition, ensure the roughness on whole driving road surface. The inspection well is polluted by a large amount of mixtures during tunnel asphalt pavement construction to the greatest extent, the flatness around the inspection well is improved, and the construction problem of smooth running surface is ensured. The construction and the modularization installation of the road surface of being convenient for have been realized, and the effect of saving the cost of labor.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept herein, and it is intended to cover all such modifications and variations as fall within the scope of the utility model.
