Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of highway maintenance engineering construction quality detection, and particularly relates to a synchronous chip seal construction material dosage on-site detection device. BACKGROUND

[0002] The so-called synchronous chip seal in the preventive maintenance of highway pavement is that special synchronous chip seal vehicles are used to uniformly spread (sprinkle) asphalt binder (hot-melt modified asphalt or normal-temperature modified emulsified asphalt, etc.) and single-particle-diameter chips on the existing pavement to form an asphalt chip wearing layer. Generally, the synchronous chip seal is divided into single-layer or double-layer structures, is suitable for a preventive maintenance measure taken before the structural damage and diseases of the asphalt pavement occur, and can effectively treat the slight or local diseases, slow down the aging speed of the asphalt pavement, fill and cure the cracks of the asphalt pavement, improve the water resistance, skid resistance and wear resistance of the asphalt pavement, and effectively prolong the service life of the road and improve the traffic service quality.

[0003] It is known that the material dosage directly affects the engineering quality in the synchronous chip seal construction process. If the asphalt spreading amount is too small, the asphalt cannot bind and stabilize the chips, which easily leads to the falling of the chips; if the asphalt spreading amount is too large, the oil overflow easily affects the skid resistance; if the chip spreading amount is too small, the coverage rate of the chips is insufficient, and the dense wearing layer cannot be formed; and if the chip spreading amount is too large, the chips are overlapped and wasted, and a loose chip layer is easily formed, which seriously affects the surface function of the synchronous chip seal and easily causes the "flying stone" phenomenon after the traffic is opened, which is not conducive to the traffic safety.

[0004] Therefore, the accurate control and detection of the asphalt spreading amount and the chip spreading amount are crucial to ensure the seal quality and the use performance.

[0005] At present, for the on-site detection of the asphalt and chip spreading amount of the synchronous chip seal, the "Highway Subgrade and Pavement On-site Test Specification" (JTG 3450-2019) and some provincial and municipal local standards mainly adopt the sample disc detection method. The sample disc is a metal shallow disc, that is, a disc with an area of not less than 1000 or 2000 cm 2, a metal disc with a depth of not more than 1 cm, 2 sample receiving discs are respectively placed at any position on the road surface where the synchronous chip sealing vehicle passes through and avoids the wheel trace at 1 / 3 length of the predetermined construction section, then the sample receiving discs that have received asphalt (chips) are taken away and taken back to the laboratory to separate and weigh the asphalt (chips) by using the solvent method or the combustion method to calculate the respective amount of asphalt (chips). A large number of engineering practices show that this method has the following problems in practical application: first, the bottom surface of the metal receiving disc is easy to have asphalt and chips splashing when receiving materials, and the vertical surface of the metal receiving disc is easy to adhere to asphalt, which affects the detection accuracy; second, the sample receiving disc method does not consider the instant detection of asphalt spraying temperature and the synchronous sealing vehicle spraying (spreading) driving speed, and cannot provide feedback construction parameters for on-site operation; third, the synchronous chip sealing construction speed is fast, and the sample receiving disc containing asphalt (chips) needs to be taken to the laboratory for detection after receiving materials, which consumes a long time for the round trip between the work site and the laboratory, and the detection result has a serious lag problem, which cannot provide timely and rapid feedback and guide on-site construction, and when the amount of asphalt (chips) is greatly deviated or unqualified, the quality control effect in the construction process is lost, which not only leads to great difficulty in chip sealing return work, but also causes great economic loss, and seriously affects the overall effect and use performance of the synchronous chip sealing; fourth, the synchronous chip sealing requires a single particle size for the chip particle composition, and if a special processing method or screening and dust removal treatment is not adopted for the designed chip specification, the actual construction often has problems of super particle size particles, too small particle size particles and excessive dust content, which seriously affects the bonding between the chips and the asphalt and affects the uniformity of the chip sealing surface structure and the anti-skid performance; in the on-site detection method of the related technology, the actual spraying (spreading) amount of asphalt and chips at the detection point is not detected and judged together with the actual situation of the chip particle composition.

[0006] Therefore, it is of great practical significance to develop an efficient, convenient and rapid synchronous chip sealing construction material amount on-site detection device to improve the accuracy of the existing on-site detection method, effectively guide on-site construction and improve the use performance of the chip sealing.

DETAILED DESCRIPTION

[0034] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0035] In the present disclosure, the orientation words such as "up, down" used herein generally refer to the "up, down" of the corresponding components in the use state in the direction of gravity, and "inner, outer" refers to the "inner, outer" relative to the outline of the corresponding component itself. In addition, the terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance. In the following description, when referring to the drawings, the same reference numerals in different drawings represent the same or similar elements, unless otherwise explained.

[0036] The so-called synchronous chip seal in the preventive maintenance of highway pavement is to uniformly spread (sprinkle) asphalt binder (hot melt modified asphalt or normal temperature modified emulsified asphalt, etc.) and single-particle-size chip on the existing pavement by using a special synchronous chip seal vehicle to form an asphalt chip wearing layer.

[0037] It is well known that the material consumption directly affects the engineering quality during the synchronous chip seal construction process. If the asphalt spreading amount is too small, the chips cannot be bonded and stabilized, which easily leads to chip falling off; if the asphalt spreading amount is too large, it is easy to cause oil overflow and affect the skid resistance; if the chip spreading amount is too small, it leads to insufficient coverage of the chips, and a dense wearing layer cannot be formed; if the chip spreading amount is too large, it leads to chip overlapping and waste, and a loose chip layer is easily formed, which seriously affects the surface function of the synchronous chip seal and causes the "flying stone" phenomenon after the traffic is opened, which is not conducive to traffic safety.

[0038] Therefore, the accurate control and detection of the asphalt spreading amount and the chip spreading amount are crucial to ensure the seal quality and performance.

[0039] Currently, for the on-site detection of the asphalt and chip spreading amount of the synchronous chip seal, the "sample plate detection method" is mainly adopted in the "Highway Subgrade and Pavement On-site Test Specification" (JTG 3450-2019) and some provincial and municipal local standards. The sample plate is a metal shallow plate, i.e., a metal plate with an area not less than 1000 or 2000 cm 2 , and a depth not greater than 1 cm. Two sample plates are placed at any position on the road surface at a distance of 1 / 3 of the length of the predetermined construction section, and the synchronous chip seal vehicle passes through and avoids the wheel trace. Then, the sample plates with asphalt (chips) are taken away and taken back to the laboratory for separation and weighing of the chips and asphalt by the solvent method or the combustion method, and the respective amounts of asphalt (chips) are calculated. A large number of engineering practices show that this method has the following problems in actual application: first, the bottom surface of the metal plate is easy to splash asphalt and chips during material receiving, and the vertical surface of the metal sample plate is easy to adhere to asphalt, which affects the detection accuracy; second, the sample plate method does not consider the immediate detection of the asphalt spreading temperature and the spreading speed of the synchronous chip seal vehicle, and cannot provide feedback construction parameters for on-site operation; third, the synchronous chip seal construction speed is relatively fast, and the sample plates containing asphalt (chips) need to be taken to the laboratory for detection after receiving the material. Due to the long time consumed for the round trip between the work site and the laboratory, the detection results have a serious lag problem, and cannot provide timely and rapid feedback and guidance for on-site construction. When the asphalt (chip) consumption deviates greatly or is unqualified, the quality control function of the construction process is lost, which not only leads to great difficulty in seal return work, but also causes great economic loss, and seriously affects the overall effect and performance of the synchronous chip seal. Secondly, the synchronous chip seal requires a single particle size for the chip particle composition. If a special processing method or screening and dust removal treatment is not adopted for the designed chip specification, the actual construction will often have problems such as super particle size, too small particle size, and excessive dust content, which seriously affect the bonding between the chips and the asphalt, the uniformity of the chip seal surface structure, and the skid resistance; in the existing on-site detection method, the actual asphalt and chip spreading amount at the detection point is not detected and judged together with the actual chip particle composition at that time.

[0040] Therefore, it has important practical significance to develop an efficient, convenient and rapid synchronous chip seal construction material dosage on-site detection device to improve the accuracy of the existing on-site detection method, effectively guide the on-site construction and improve the performance of the chip seal.

[0041] According to the embodiments of the present application, referring to Figures 1 to 9 The synchronous chip seal construction material dosage on-site detection device is provided, which comprises a sample receiving assembly 1, a vehicle frame 2, a cleaning and separating system 3, a weighing assembly 4, a controller 5, a temperature sensor 19 and a speed radar 7.

[0042] As shown in Figure 2 and Figure 3 The sample receiving assembly 1 comprises a sample receiving frame 11, a sample receiving cloth 12 and a clamping frame 13. The sample receiving frame 11 is a bottomless frame structure penetrating from top to bottom. The sample receiving cloth 12 is detachably fixed to the sample receiving frame 11 through the clamping frame 13, so that the sample receiving frame 11 and the sample receiving cloth 12 form a containing cavity with the sample receiving cloth 12 as the bottom. The containing cavity is used to contain the asphalt chip seal formed by the asphalt binder and the single-diameter chip. The sample receiving cloth 12 can be a high-temperature flexible sample receiving cloth.

[0043] As shown in reference 1, the vehicle frame 2 comprises a vehicle compartment 21 and wheels 22 located at the bottom of the vehicle compartment 21. The vehicle compartment 21 serves as a carrier for carrying other components of the detection device, and the wheels 22 facilitate the movement of the detection device.

[0044] The cleaning and separating system 3 is arranged in the vehicle compartment 21 and is used to clean and separate various components in the asphalt chip seal formed by the synchronous chip seal construction material. The weighing assembly 4 is used to weigh the weight of various components.

[0045] The controller 5, the temperature sensor 19 and the speed radar 7 are electrically connected to the controller 5. The temperature sensor 19 is arranged on the upper surface of the sample receiving cloth 12 and is used to obtain the spreading temperature of the asphalt. The speed radar 7 is arranged on the vehicle frame 2 and is used to obtain the driving speed of the synchronous chip seal vehicle.

[0046] In the above embodiment, when detecting the asphalt chip wearing layer formed in the synchronous chip sealing construction process, the sampling frame 11 is first placed on the sampling point on the road surface. Since the sampling frame 11 is a bottomless frame structure penetrating from top to bottom, the sampling support cloth 12 is laid in the sampling frame 11 and fixed on the sampling frame 11 by the clamping frame 13. The sampling frame 11 and the sampling support cloth 12 form a containing cavity. After spraying asphalt and spreading chips by the synchronous chip sealing vehicle, the asphalt chip wearing layer is formed in the containing cavity. The asphalt chip wearing layer is placed into the cleaning and separating system 3 for cleaning, separating and classification according to particle size, and the weight of the chip in the set particle size range is obtained by the weighing assembly to calculate the weight of the asphalt. Compared with the detection method in the related art, the synchronous chip sealing construction material dosage on-site detection device has the following advantages: 1. The sampling support cloth 12 is made of high-temperature flexible material, which can effectively prevent the asphalt and chip spatter phenomenon caused by the synchronous chip sealing vehicle passing through the detection point when spraying asphalt and spreading chips; 2. The temperature sensor for obtaining the asphalt spraying temperature and the speed radar for obtaining the working speed of the synchronous chip sealing vehicle are additionally arranged at the sampling detection point, which can feed back the asphalt and chip unit area material dosage detection results to the synchronous chip sealing construction operation site at the same time, which is more conducive to guiding the on-site construction operator to optimize the construction parameters, and can timely and quickly correct the deviation and correct the deviation, thereby improving the construction quality; 3. The synchronous chip sealing construction material dosage on-site detection device adopts a mobile design, which can be used not only for rapid detection on the construction site, but also for indoor detection and analysis. At the same time, the device is not only suitable for synchronous chip sealing preventive maintenance engineering, but also suitable for the construction site detection of synchronous chip sealing as the stress absorbing layer of the asphalt pavement. The detection result can be fed back in time and guide the on-site construction; 4. The cleaning and separating system can accurately judge the single particle size particle composition quality of the chip for synchronous chip sealing, which is conducive to guiding the chip quality and surface structure quality control after construction on the construction site.

The size of the metal sampling frame 11 can be selected as 1 cm thick, 40 cm x 60 cm in net size of the inner frame, and 1 cm wide of the metal edge.

The vertical cloth 122 tightly abuts the inner side surface of the sampling frame 11, and the pressing edge cloth 123 can be formed by outwardly folding the cloth outwardly extended from the vertical cloth 122.

[0049] In order to make the vertical cloth 122 close to the inner side of the sample frame 11, the sample assembly 1 further comprises a plurality of magnets 14 fixed to the outer side of the vertical cloth 122.

The bottom self-adhesive isolation film 16, the vertical self-adhesive isolation film 17 and the top self-adhesive isolation film 18 can be selected from silicone oil paper.

[0061] The implementation principle of the present application will be described below in combination with the specific implementation steps of obtaining the asphalt broken stone wearing layer sample and detecting the sample in the specific construction process:

[0062] First step: Move the synchronous broken stone seal coat construction material dosage site detection device to the side of the synchronous broken stone seal coat vehicle construction operation surface in a safe place, place one sample receiving assembly on each wheel track at the starting 1 / 3 length of the predetermined detection construction road section as the selected detection point, and at the same time, rotate the speed radar 7 on the vehicle frame to the front direction of the synchronous broken stone seal coat vehicle.

[0063] Second step: Sample receiving assembly installation. First, place the sample receiving frame (1 cm thick, inner frame net size 40 cm x 60 cm, metal edge width 1 cm) on the selected road surface detection point, and the long side direction of the sample receiving frame is consistent with and relatively parallel to the advancing direction of the synchronous broken stone seal coat vehicle. Then, lay the sample receiving support cloth along the inner wall of the sample receiving frame, use the high-temperature-resistant and flexible support cloth embedded magnetic block to make the bottom support cloth flat and magnetically attract the inner vertical wall of the sample receiving frame, and the bottom support cloth forms a sample receiving surface with a bottom surface of 40 cm x 60 cm, embed the pulling rope into the groove of the sample receiving frame, and place a clamping frame (0.3 cm thick) with the same size as the outer shape size of the sample receiving frame on it. Finally, stick a layer of high-temperature-resistant bottom surface self-adhesive isolation film along the laid bottom support cloth, and stick a layer of high-temperature-resistant vertical surface self-adhesive isolation film (such as silicone oil paper) on the vertical surface of the clamping frame. The top surface of the clamping frame also needs to be pre-stuck with a layer of high-temperature-resistant top surface self-adhesive isolation film.

[0064] Third step: according to the single particle size of the stone used in the synchronous chip seal, the aperture of the super particle size square hole screen is determined. For example: the minimum particle size and the maximum particle size range from 3mm to 5mm, the super particle size square hole screen selects 6mm; the minimum particle size and the maximum particle size range from 4mm to 7mm, the super particle size square hole screen selects 8mm; the minimum particle size and the maximum particle size range from 5mm to 8mm, the super particle size square hole screen selects 9mm; the minimum particle size and the maximum particle size range from 8mm to 10mm, the super particle size square hole screen selects 11mm; the minimum particle size and the maximum particle size range from 8mm to 11mm, the super particle size square hole screen selects 12mm; the minimum particle size and the maximum particle size range from 12mm to 15mm, the super particle size square hole screen selects 16mm. The corresponding minimum particle size square hole screen basket, maximum particle size square hole screen basket and super particle size square hole screen basket are combined in order, and are installed on the rotating shaft in layers in order, so that the third clamping sleeve of the minimum particle size square hole screen basket is clamped with the lower protruding part of the rotating shaft, the second clamping sleeve of the maximum particle size square hole screen basket is clamped with the middle protruding part of the rotating shaft, and the third clamping sleeve of the super particle size square hole screen basket is clamped with the upper protruding part of the rotating shaft. The rotating shaft can drive the minimum particle size square hole screen basket, the maximum particle size square hole screen basket and the super particle size square hole screen basket to rotate at the same time. Finally, the shaft rod clamping piece above the cleaning cylinder is installed and fixed.

[0065] Fourth step: set the test parameters of the controller; first, set the cleaning solvent pumping amount (the solvent selected is an environmentally friendly solvent with high volatility and can quickly dilute asphalt, and the amount is not less than 1 / 3 of the height of the cleaning cylinder capacity), solvent cleaning and separation time (10min-15min), solvent cleaning and separation times (1-2 times), power motor rotation speed (fast, medium, slow); then set the hot air dryer (to promote solvent volatilization and appropriately reduce the moisture content of the gravel, reduce the weighing error of the gravel) working parameters, hot air temperature (85℃-105℃), hot air dryer working time (5min-10min); wherein, when the hot air dryer is running, the power motor is set to fast rotation by default, and high speed rotation can promote the rapid volatilization of residual solvent and trace moisture.

[0066] The fifth step: when the synchronous chip seal vehicle passes through two detection points to assemble the sample receiving assembly, the embedded temperature sensor on the bottom surface of the sample receiving cloth automatically collects the asphalt spraying temperature, and the 360° rotating speed radar on the vehicle frame automatically collects the driving speed of the synchronous chip seal vehicle. When the synchronous chip seal vehicle passes through the detection point and the hot melt asphalt reaches room temperature or the emulsified asphalt is slightly demulsified, the clamping frame is removed, the vertical self-adhesive isolation film is torn off, the pulling rope is lifted, the bottom cloth containing asphalt and gravel is collected and placed in the metal tray, the asphalt and gravel mixture is weighed, and then they are poured into the super particle size square hole screen basket together; when the bottom surface self-adhesive isolation film or the vertical self-adhesive isolation film on the sample receiving cloth is peeled off, if there is a small amount of asphalt or gravel adhered to the surface of the bottom surface self-adhesive isolation film or the vertical self-adhesive isolation film, the gravel particles should be peeled off and poured into the super particle size square hole screen basket, and the adhered asphalt should be weighed and recorded.

[0067] The sixth step: turn on the cleaning and separation system start switch, and then turn on the hot air drying start switch after the cleaning and separation are completed, so as to complete the set operation; when the gravel reaches room temperature, the maximum particle size square hole screen basket and the minimum particle size square hole screen basket are weighed and recorded respectively.

[0068] The seventh step: the residues of the 0.075mm square hole screen in the filter box assembly and the residues on the waste liquid filter paper smaller than 0.075mm are weighed and recorded respectively on site by using the combustion method.

[0069] The eighth step: according to the recorded weighing results, the asphalt and gravel spraying amounts per unit area of the synchronous chip seal are calculated respectively according to the formula, and the asphalt spraying temperature, asphalt and gravel spraying speed of each of the two measurement points are recorded, and the weather conditions at the construction site are recorded, the test data are sorted, and the synchronous chip seal construction material consumption test report is issued on site.
