Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to sampling equipment for road engineering. Background Art

[0002] Road engineering refers to the whole process of planning, design, construction, maintenance and management work with roads as the object and the engineering entity involved. Like any other type of civil engineering, road engineering has obvious technical, economic and management characteristics. According to the service scope and its position and role in the national road network, it is divided into: ① National Highway (national highway), including expressways and main trunk lines; ② Provincial Highway (regional highway); ③ County and township roads (local highways); ④ Urban roads. The first three are collectively referred to as highways, which can be divided into five technical levels according to the annual average day and night automobile traffic volume and the use tasks and nature. Different levels of highways are reflected by different technical indicators. These indicators mainly include calculated vehicle speed, number and width of lanes, roadbed width, minimum flat curve radius, maximum longitudinal slope, sight distance, road surface grade, bridge and culvert design load, etc.

[0003] The application number is CN202221900910.1, which discloses a municipal road engineering thickness detection device, which relates to the field of road engineering. This municipal road engineering thickness detection device includes a base, a drive assembly and a sampling barrel. The upper surface of the base is provided with a support frame, the drive assembly is installed on the base, and the drive assembly is used to drive the sampling device. The sampling barrel is installed below the drive assembly, and the sampling barrel is driven to rotate by the drive assembly. A clamping mechanism is installed inside the sampling barrel to facilitate the removal of samples. The clamping mechanism includes a plurality of clamping blocks, and the clamping blocks are slidably connected to the inside of the sampling barrel, and the bottom of the clamping block is set as an inclined surface to facilitate clamping samples. This municipal road engineering thickness detection device is convenient for clamping and removing samples, reducing the time of tools and increasing work efficiency.

[0004] Although the above utility model drives the sampling barrel to rotate through the driving assembly, a clamping mechanism is installed inside the sampling barrel to facilitate the removal of samples. The clamping mechanism includes a plurality of clamping blocks, which are slidably connected to the inside of the sampling barrel, and the bottom of the clamping block is set as an inclined surface to facilitate clamping the sample. This municipal road engineering thickness detection equipment is convenient for clamping and removing samples, reducing the time of tools and increasing work efficiency, but there is a disadvantage that the roller at the bottom of the device will cause the device to move when not in use, and the device that cannot be fixed will cause inaccurate and poor sampling during the sampling process.

[0005] Therefore, it is necessary to replace the roller of the device with a foldable storage method so that the roller can be put down when in use. The roller can be folded and stored in a fixed position to keep the machine in a fixed state. The changeable roller assembly can make the use of the device more convenient. Utility Model Content
