Description
Technical Field
The utility model relates to the field of measuring tools, in particular to a road structure layer construction thickness measuring instrument.
Background
Along with the rapid promotion of the urbanization process, the urban road construction is the necessary public infrastructure in the national towanization process, mainly the asphalt pavement road, the road construction quality is one of the important targets of project implementation, and particularly the structural layer paving thickness of the municipal road is taken as an important management and control link in the construction process.
The current road construction paving thickness quality inspection and acceptance mostly takes drill core sampling measurement as a main part, the measurement method is more accurate, but the method is mainly a post management and control means, the paving thickness control method in the structural layer construction process is lack of a uniform precise measurement means, the management and control methods of all construction units are uneven, and particularly, the phenomena that the paving thickness of the surface layer construction is uneven and even the thickness does not reach the standard often occur.
Most of asphalt surface layer paving thickness measuring means in the existing construction process are simple and easy drill rod inserting methods, namely a drill rod made of a thin steel bar is used, a nut is welded at the bottom of the drill rod according to the designed paving thickness to mark the thickness dimension position, and manual random insertion is carried out in the asphalt mixture paving process to check whether the paving thickness of the asphalt mixture reaches the standard or not.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the utility model provides the road structure layer construction thickness measuring instrument which can simply and quickly obtain the road construction paving thickness condition, has higher measuring precision and more convenient use, and has lighter overall structure, convenient carrying and very low cost.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the road structure layer construction thickness measuring instrument comprises a base, a sliding column, a sliding piece and a marking needle;
the sliding column is vertically fixed on the upper surface of the base, and scales for indicating the distance between the sliding column and the lower surface of the base are arranged on the sliding column;
the sliding piece is in sliding fit with the sliding column, and the marking needle is fixed downwards on the sliding piece.
The sliding columns are vertically arranged on the base, the sliding columns are in a vertical state relative to the ground when the base is placed on the ground, the marking needles are downwards arranged on the sliding pieces and are downwards inserted into the ground, the marking needles downwards move, the moving distance of the sliding pieces indicates the depth of the marking needles entering the ground, and therefore the road construction paving thickness can be reflected through the condition that the marking needles enter the ground.
Preferably, the sliding part is of a ring sleeve structure, and the ring sleeve structure is sleeved on the sliding column. The firmness of the matching between the sliding piece and the sliding column is improved.
Preferably, the upper end of the needle is hinged to the slider. The marking needle is arranged in a hinged mode, so that the marking needle can be stored more conveniently and flexibly, and the downward inserting direction is more flexible.
Preferably, the lower end of the marking needle is provided with a cutting edge. The marking needle can be conveniently inserted into the ground downwards.
Preferably, the top of the sliding column is provided with a handle. Be convenient for through the handle stabilization traveller, avoid crooked, can better carry through it simultaneously.
Preferably, the lower part of the sliding column is provided with a guide cylinder corresponding to the marking needle, and the marking needle downwards penetrates through the guide cylinder. The sliding direction of the two-point limiting marker needle is convenient for being vertically inserted into the ground downwards through the guide cylinder and the sliding piece.
Preferably, the sliding column is arranged at the edge of the base. The marking needle can be conveniently inserted into the ground by avoiding the base downwards.
The utility model has the beneficial effects that:
through the mode, the road construction paving thickness condition can be simply and quickly obtained, the measurement precision is higher, the use is more convenient, the overall structure is lighter, the carrying is convenient, and the cost is very low.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the description of the embodiments will be briefly introduced below, it is obvious that the drawings in the following description are only one of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
wherein, base 1, traveller 2, handle 3, slider 4, scale 5, mark needle 6, guide cylinder 7.
Detailed Description
For the purpose of enhancing the understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and examples, which are provided for the purpose of illustration only and are not intended to limit the scope of the present invention.
Examples
As shown in fig. 1, the road structure layer construction thickness measuring instrument comprises a base 1, a sliding column 2, a sliding piece 4 and a marking pin 6.
The sliding column 2 is vertically fixed on the upper surface of the base 1, and scales 5 for indicating the distance between the sliding column 2 and the lower surface of the base 1 are arranged on the sliding column.
The sliding piece 4 is matched on the sliding column 2 in a sliding mode, and the marking needle 6 is fixed on the sliding piece 4 downwards.
The sliding column 2 is vertically arranged on the base 1, the sliding column 2 is in a vertical state relative to the ground when the base 1 is placed on the ground, the marking needle 6 is downwards arranged on the sliding piece 4, the marking needle 6 is downwards inserted into the ground, the marking needle 6 moves downwards, and the depth of the marking needle 6 entering the ground is represented by the moving distance of the sliding piece 4, so that the road construction paving thickness can be reflected by the condition that the marking needle 6 enters the ground.
