The measurer comprises a transparent cylinder, a glass plate and a cake-shaped flattening and compacting hammer, wherein the transparent cylinder is used for accommodating standard sand and reading the height of the standard sand, and the outer wall of the cylinder is provided with scales; the glass plate is used for preventing the standard sand from leaking; the cake-shaped flattening and compacting hammer is used for flattening and compacting the standard sand in the cylinder, and a lifting handle is arranged on the top end of the flattening and compacting hammer; the glass plate is arranged below the cylinder and is detachably connected with the cylinder; the flattening and compacting hammer is connected with the cylinder through a connecting line. The measurer is simple in structure, convenient to operate and high in determination accuracy; the texture depth of the pavement can be measured by the measurer, the steps of measuring the standard sand, paving the standard sand by using a flat plate, measuring the circular pavement area and the like in the traditional sand pavement method can be eliminated, the system error and the random error are reduced and the operation difficulty is reduced.
Description
Technical field
The utility model relates to a kind of manual sanding gear, is specifically related to a kind of manual sanding gear for measuring the road surface construction degree of depth.
Background technology
The construction depth of road surface (TD), claim again texture depth, is the important indicator of surface roughness, refers to the mean depth of the rough open pores of road surfaces of certain area.Be mainly used in evaluating macro-asperity, drainability and the cling property of road surface.
Traffic accident and pavement skid resistance condition have much relations, particularly, in the larger area of amount of precipitation,, if the flexible pavement surface does not have good cling property, are easy to accident.And pavement skid resistance condition directly is subject to the impact of pavement structural depth.Therefore, one of emphasis of the antiskid problem of the flexible pavement of present stage solution is the construction depth that detects road surface.
The most also that the method for commonly using the most is manual sand patch method and electronic sand patch method on engineering at present.Manual sand patch method is due to manually-operated, and its measure error is larger.The main cause that causes error has: be difficult to guarantee to pave into rule while 1, paving circular; 2, be difficult to guarantee that the sanding surface is plane; 3, the error of diameter measurement; 4, be difficult to guarantee to pave evenly; 5, be bulldozed the plate operate miss that paves and easily cause repeated work.
Summary of the invention
Measure the larger problem of construction depth error for the traditional-handwork sand patch method, the utility model proposes a kind of determinator of pavement structural depth, can effectively improve the mensuration precision.
In order to realize above-mentioned task, the utility model by the following technical solutions:
A kind of determinator of pavement structural depth comprises:
One is used for the transparent cylindrical drum of holding standard sand and reading the standard sand height, is provided with scale on the outer wall of cylindrical drum;
One is used for the glass plate that prevents that standard sand from revealing;
Smooth and the smooth compacting hammer of round pie compacting of standard sand that is used for putting into cylindrical drum, be provided with handle on the top of smooth compacting hammer;
Wherein, described glass plate is arranged on the below of cylindrical drum, and glass plate and cylindrical drum are dismountable connected mode; Smooth compacting hammer is connected with cylindrical drum by connecting line.
Further, the external diameter of described smooth compacting hammer is less than the internal diameter of cylindrical drum.
Further, described glass plate is the square glass plate, and the length of side of glass plate is greater than the external diameter of described cylindrical drum.
Further, the barrel thickness of described cylindrical drum is 5mm.
Technique effect of the present utility model is:
This apparatus structure is simple, and is easy to operate, measures precision high; Utilize this device to carry out pavement structural depth and measure, can omit measurement standard sand in traditional sanding method, utilize flat board standard sand and the measurement circle steps such as area that pave that pave, reduced systematic error and random error, reduced operation easier.
