Abstract

The utility model discloses a bitumen application rate detection device. The bitumen application rate detection device is characterized in that a nozzle on the outermost side on a bitumen pipe of a trail portion of a bitumen scattering vehicle is chosen as a detection nozzle. A receiving sample vessel used for receiving all bitumen ejected from the detection nozzle is connected with the detection nozzle. The receiving sample vessel contains bitumen detection samples. According to the weight of the bitumen detection samples and the area of a detected pavement covered by the bitumen ejected from other nozzles on the bitumen pipe, the bitumen application rate of per square face of the detected pavement is calculated and then is achieved. The bitumen application rate detection device directly contains the detection sample by the receiving sample vessel so as to quickly and accurately achieve the bitumen application rate of per square face of the detected pavement to direct construction.

Description

A kind of pitch spreading amount checkout gear

Technical field

The utility model relates to the checkout gear of express highway pavement construction medium pitch spreading amount.

Background technology

Express highway pavement thoroughly layer, adhesion coating, seal construction adopts pitch sprinkling car to construct with spraying, according to the E60-2008 rules, for the test of the pitch spreading amount in the construction of asphalt distribution method, is area will be not less than 0.1m ²Two platter be placed on the optional position of spreading width, treat that the platter that will fill pitch after the truck spreader spreading pitch removes from the road surface, to take by weighing weight and to calculate, the artificial benefit spread the blank space that platter stays on the position of original placement platter again.But in the practical application, press the method for E60-2008 rules, there are the following problems:

Can produce sputter when 1, pitch sprays on the platter, thereby cause testing result less than normal;

2, the area of test is subject to the restriction of platter area, and sample representation is relatively poor;

3, when seal is constructed, when the method in the employing E60-2008 rules detects, sample in the platter is the weight sum of rubble and pitch, therefore can not directly draw the spreading concentration of pitch, follow-up rubble will being picked out, and clean, claim its weight behind the dry rubble with gasoline or trichloro-ethylene, and then extrapolate thus the spreading concentration of pitch.This complicated process causes testing result can not be used for timely guiding construction.

Summary of the invention

The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of pitch spreading amount checkout gear is provided, to improve the representativeness of layer, adhesion coating, the test of seal pitch spreading amount, shorten the test period of crushed stone sealing pitch spreading amount, accurately Fast Measurement pitch sprinkling amount.

The utility model technical solution problem adopts following technical scheme:

The design feature of the utility model pitch spreading amount checkout gear is to select to be on the pitch truck spreader afterbody pitch pipeline an outermost nozzle for detecting nozzle, accepts one at described detection nozzle and is used for taking in and is subjected to the sample ware by whole pitches of described detection nozzle ejection.

The utility model pitch spreading amount detection method is to select to be on the pitch truck spreader afterbody pitch pipeline an outermost nozzle for detecting nozzle, accepts one at described detection nozzle and is used for taking in and is subjected to the sample ware by whole pitches of described detection nozzle ejection; Be subjected to the sample ware directly to take in pitch to detect sample by described, detect the area that other nozzle sprays on the weight of sample and the pitch pipeline pitch covers tested road surface according to pitch, calculate the pitch spreading amount that obtains every square of face on the tested road surface.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model method directly obtains the pitch sample, avoided the complicated procedures that in crushed stone sealing construction, carries out pitch and rubble sorting, testing result can reflect the seal construction quality quickly and accurately, in time be used for guiding construction, effectively control cost, simultaneously because the increase of its test area has realized on-the-spot overall control.

2, the sampling sample that obtains of the utility model method can reach 30m ², in the E60-2008 rules only with 0.1m ²Sampling Area greatly improved the representativeness of sample, improve the accuracy of test result, and save artificial benefit and spread program.

Number in the figure: 1 detects nozzle; 2 are subjected to the sample ware; 3 pitch pipelines; 4 pitch truck spreaders.

The specific embodiment

Referring to Fig. 1, the present embodiment medium pitch spreading amount checkout gear is to select to be on the afterbody pitch pipeline 3 of pitch truck spreader 4 an outermost nozzle for detecting nozzle 1, accepts one and is used for taking in and is subjected to sample ware 2 by whole pitches of described detection nozzle 1 ejection detecting nozzle 1.

Such as Fig. 1, Fig. 2 and shown in Figure 3, the present embodiment medium pitch spreading amount detection method is to operate as follows:

1, selects to be on the pitch truck spreader afterbody pitch pipeline 3 an outermost nozzle for detecting nozzle 1, accept one and be used for taking in and be subjected to sample ware 2 by whole pitches of described detection nozzle 1 ejection detecting nozzle 1.

2, the flow of all nozzles is consistent on the adjustment truck spreader, guarantees that each nozzle spreading is even;

3, at the pitch truck spreader from starting point A in the at the uniform velocity driving process to terminal point B, detect the pitch of ejection in the nozzle 1 all by taken in by sample ware 2, the pitch of other each nozzle ejection is spread in uniform on the road surface, obtaining a width is that K, length are the pitch spreading face of L, and the area of this pitch spreading face is K * L; Wherein, K is the cover width that N nozzle sprays pitch; In order to guarantee the accuracy of measurement result, need to guarantee that the pitch that detects ejection in the nozzle 1 can not leak in being subjected to the sample ware, simultaneously, the pitch in other nozzle can not spray in being subjected to the sample ware yet; The even travel speed V of pitch truck spreader can remain on 8-20km/h;

4, the pitch spreading amount S of every square of face is on the tested road surface of calculating:

S=(m ₂-m ₁)N/K/L (1)

In the formula (1):

L is that starting point A is to the distance of terminal point B;

m ₁For being subjected to sample ware weight; m ₂For being subjected to the pitch weight that the sample ware takes in and being subjected to sample ware weight sum;

N is the nozzle number that all except detecting nozzle of pitch truck spreader afterbody pitch pipeline spray pitch.

Claims (1)

1. pitch spreading amount checkout gear, it is characterized in that selecting being on the pitch truck spreader afterbody pitch pipeline (3) an outermost nozzle for detecting nozzle (1), accept one at described detection nozzle (1) and be used for taking in and be subjected to sample ware (2) by whole pitches of described detection nozzle (1) ejection.
