Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of detection equipment, and particularly relates to a highway water permeation detection device. BACKGROUND

[0002] Highways are usually asphalt concrete pavements. If the water permeation coefficient of the asphalt concrete pavement does not meet the design requirements, diseases such as pits and loose are prone to occur. Water seeping along the diseases to the base and soil base will cause local water damage, and even seriously reduce the bearing capacity of the roadbed. At present, a road surface water permeation detection device is usually used in road construction to measure the amount of water permeating into a certain area of the road surface per unit time, which is used as the water permeation coefficient of the road surface.

[0003] In the prior art, the road surface water permeation detection device usually comprises a base, a guide pipe, a fixing seat, a valve, a measuring cylinder and a sealing ring. The base comprises an inner cavity, which is located at the lower central part of the base and extends downwardly through the bottom surface of the base. The guide pipe is located above the base and one end of the guide pipe is connected to the base. The fixing seat is located above the guide pipe and is connected to the other end of the guide pipe. The valve is arranged at the guide pipe to control the flow of liquid in the guide pipe. The measuring cylinder is located above the fixing seat and is inserted into the fixing seat from above the fixing seat. The sealing ring is in close contact with the inner cavity of the base. During the sealing test, a heavy iron ring is used to press the base of the instrument to prevent water from flowing out between the base and the road surface due to excessive pressure. The valve on the guide pipe is closed, water is filled into the measuring cylinder above the instrument, the valve is opened, and the water in the measuring cylinder fills the inner cavity of the base. The valve is closed again, water is filled into the measuring cylinder again, and the valve is opened. The water permeation coefficient of the asphalt pavement can be detected by observing the change in the scale of the water level within a certain period of time.

[0004] The sealing property between the device and the road surface is an important factor affecting the accuracy of the water permeation detection device. If the sealing is not good, water will seep out from the side, which will greatly affect the accuracy of the detection result.

[0005] Most of the current water permeation detection devices use sealing rings or sealing materials such as glue and paraffin for sealing. However, due to the existence of many gaps on the surface of the road, the sealing effect of the sealing ring is poor. The sealing materials such as glue and paraffin can penetrate into the gaps, so the sealing effect is good. On the one hand, when using sealing materials for sealing, the operation is relatively complicated and may leak to the inside, resulting in a decrease in the water permeation area. On the other hand, the sealing materials have the problems of complicated operation, difficult recovery and easy pollution of the road surface. SUMMARY

[0006] The present application provides a highway water permeation detection device, which aims to provide a water permeation detection device with good sealing effect, simple operation and less pollution to the road surface.

[0058] Please refer to Figures 1 to 9The present application provides a highway water permeation detection device. The highway water permeation detection device comprises a base, a support, a sealing sleeve 30, a heat guiding assembly, a heating assembly 50, a driving assembly, a measuring cylinder 70 and a valve 80. The base is provided with a guide hole. The support is arranged on the upper side of the base and is connected with the base. The sealing sleeve 30 is slidingly arranged in the guide hole, the upper end of the sealing sleeve 30 is connected with and communicates with the valve 80, and the lower end of the sealing sleeve 30 is used for inserting into the asphalt pavement. The heat guiding assembly comprises a connecting frame 41 and a plurality of guiding needles 42. The plurality of guiding needles 42 are arranged in a circumferential direction of the sealing sleeve 30 at intervals. The guiding needles 42 penetrate the sealing sleeve 30 in an axial direction of the sealing sleeve 30 and are slidingly connected with the sealing sleeve 30. The guiding needles 42 are used for extending downwardly out of the sealing sleeve 30 and inserting into the asphalt pavement. The connecting frame 41 is arranged on the upper side of the sealing sleeve 30 and is connected with the guiding needles 42. The heating assembly 50 is in heat conduction connection with the guiding needles 42 and is used for heating the guiding needles 42. The driving assembly is connected with the support. The power output end of the driving assembly is connected with the sealing sleeve 30 and the connecting frame 41 and is used for driving the heat guiding assembly and the sealing sleeve 30 to move up and down. The measuring cylinder 70 is arranged on the upper side of the sealing sleeve 30 and communicates with the sealing sleeve 30. The valve 80 is connected between the measuring cylinder 70 and the sealing sleeve 30.

[0059] The driving assembly drives the heat guiding assembly first, so that the guiding needles 42 insert into and heat the asphalt pavement. After a preset heating time, the driving assembly drives the sealing sleeve 30 to insert into the asphalt pavement. The preset time is a time set according to actual conditions. After the preset heating time, the asphalt pavement is softened.

[0060] Before the guiding needles 42 move downwardly, the guiding needles 42 do not protrude from the bottom surface of the sealing sleeve 30. After the asphalt pavement is softened, only the downward frictional force applied by the sealing sleeve 30 and the guiding needles 42 is insufficient to drive the guiding needles 42 to continue to move downwardly during the downward movement of the sealing sleeve 30. Therefore, the guiding needles 42 are fixed, and the sealing sleeve 30 and the guiding needles 42 slide relative to each other until the sealing sleeve 30 moves to the required depth.

[0061] It should be noted that, during detection, the detection device is placed in a to-be-detected area. The heating assembly 50 heats the guiding needles 42. After the guiding needles 42 are heated to a required temperature, the driving assembly drives the connecting frame 41 and the guiding needles 42 to move downwardly, so that the guiding needles 42 insert into the asphalt pavement and heat the asphalt pavement, so that the asphalt pavement is softened.

[0062] Then, the driving assembly drives the sealing sleeve 30 to move downwardly and insert into the softened asphalt pavement. After the asphalt pavement cools, the valve 80 is closed, a certain amount of water is injected into the measuring cylinder 70, the valve 80 is opened, and the water in the measuring cylinder 70 fills the sealing sleeve 30. Then, the valve 80 is closed again, a certain amount of water is injected into the measuring cylinder 70, and the valve 80 is opened. The water level scale change in a period of time can be observed to detect the water permeation coefficient of the asphalt pavement.

[0063] The highway water seepage detection device provided by the application has the advantages that, compared with the prior art, the highway water seepage detection device is placed in a detection area during detection, the guide needle 42 is heated by the heating assembly 50, the guide needle 42 is inserted into the asphalt pavement after being driven downward by the driving assembly and the guide needle 42 reaches a required temperature, the asphalt pavement is heated and softened, then the sealing sleeve 30 is driven downward by the driving assembly and inserted into the softened asphalt pavement, so that a good sealing effect is achieved, and the operation is simple and the pavement is not polluted; meanwhile, the heating depth of the asphalt pavement is effectively increased by the inserted guide needle 42, the heating efficiency is improved, and then the difficulty and time required for inserting the guide needle 42 into the asphalt pavement are effectively reduced, and the detection efficiency is ensured.

[0064] As shown in Figure 1 and Figure 3 in a specific embodiment of the highway water seepage detection device provided by the application, the base includes a load-bearing plate 11 and a support pad plate 12, the load-bearing plate 11 is provided with a guide hole in the middle and load-bearing areas on both sides, the load-bearing areas are used to place counterweights; the support pad plate 12 is arranged on the lower side of the load-bearing area and connected with the load-bearing plate 11.

[0065] It should be noted that the counterweights are bricks, stones, iron blocks and the like, in addition, the staff can also step on the load-bearing plate 11 to act as a counterweight. The support pad plate 12 is used to separate the load-bearing plate 11 around the sealing sleeve 30 from the ground to avoid the extruded pavement material, and at the same time, ensure a large contact area with the pavement to avoid crushing the pavement.

[0066] As shown in Figure 1 and Figure 3 in a specific embodiment of the highway water seepage detection device provided by the application, the support includes a plurality of support rods 21 and a mounting plate 22, the plurality of support rods 21 are arranged around the guide hole and connected with the base at the lower end; the mounting plate 22 is arranged on the upper side of the base and connected with the support rods 21; the driving assembly is connected with the mounting plate 22, and the graduated cylinder 70 passes through the mounting plate 22.

[0071] It should be noted that the hot air blower is an existing device capable of blowing hot air, and the temperature is set according to the softening temperature of the asphalt pavement, which is usually 70°-100°; the guide needle 42 is provided with the air vent 421, and after being inserted into the pavement, the hot air is blown out from the air vent 421, further improving the heating area and the heating efficiency.

[0072] Further, the hot air blower with a closable heating module can also be selected, and after the sealing sleeve 30 is inserted into the asphalt pavement, the heating module is closed, at this time the hot air blower blows normal temperature air, so that the pavement in the heated area is quickly reduced to normal temperature, and then detection is carried out, avoiding affecting the accuracy of the detection result.

[0073] As shown in Figure 4 and Figure 5 , in a specific embodiment of the highway water seepage detection device provided by the embodiment of the application, the sealing sleeve 30 is provided with an annular air chamber 32 in the side wall, and at least one air vent 421 on the guide needle 42 is always in the annular air chamber 32, and after the guide needle 42 is inserted into the asphalt pavement, the at least one air vent 421 is in the asphalt pavement.

[0075] As shown in Figure 1 and Figure 2As shown, in a specific implementation of the highway water seepage detection device provided by an embodiment of the present invention, the driving assembly includes a driving element 61, a guide frame 62, a driving rod 63 and a switching assembly, the driving element 61 is connected to the bracket; the guide frame 62 is connected to the power output end of the driving element 61, and is used to move up and down under the drive of the driving element 61, and a slide groove is provided on the lower side of the guide frame 62, and the slide groove extends radially along the sealing sleeve 30; the upper end of the driving rod 63 is slidably arranged in the slide groove and has the freedom to slide along the slide groove. The driving rod 63 has a first state abutting against the connecting frame 41 and a second state connected to the sealing sleeve 30; the switching assembly is used to switch the driving rod between the first state and the second state.

[0076] Specifically, the chute is a T-slot, dovetail slot, or L-slot, such as a slot that allows the drive rod 63 to move only along the direction in which the chute extends. Preferably, the chute is a T-slot, and the shape of the upper end of the drive rod 63 matches the T-slot. Two or more drive assemblies are provided, evenly spaced around the sealing sleeve 30, to ensure more balanced force on the sealing sleeve 30 and the connecting frame 41.

[0077] Further, such as Figure 1 and Figure 2 As shown, in a specific embodiment of the highway water seepage detection device provided by an embodiment of the present invention, the switching component includes an elastic element 64, a first magnet 65 and a limit plate 66. One end of the elastic element 64 is connected to the guide frame 62, and the other end is connected to the driving rod 63, so that the driving rod 63 is aligned with the connecting frame 41 in the first state; the first magnet 65 is connected to the sealing sleeve 30, so as to attract the driving rod 63 when the guide needle 42 is inserted into the asphalt pavement to a preset depth, so that the driving rod 63 moves toward the first magnet 65, aligns with the sealing sleeve 30, and switches to the second state; the limit plate 66 is provided on the lower side of the mounting plate 22 and is connected to the measuring cylinder 70. The limit plate 66 abuts against the mounting plate 22 when the sealing sleeve 30 is in the initial position (as shown in FIG.

Figure 6 As shown in FIG. 6, the first magnet 65 attracts the driving rod 63, and the attraction force is greater than the sum of the friction between the driving rod 63 and the guide frame 62, the pulling force of the elastic element 64 on the driving rod 63 and the friction between the driving rod 63 and the connecting frame 41, so that the driving rod 63 moves towards the first magnet 65 until it is attached to the first magnet 65 (for example, as shown in FIG. 6). Figure 8 As shown in FIG. 6, the driving rod 63 is aligned with the sealing sleeve 30; after the asphalt pavement is heated and softened, the driving element 61 continues to drive the driving rod 63 to move downward, the driving rod 63 pushes the sealing sleeve 30, so that the sealing sleeve 30 is inserted into the asphalt pavement (for example, as shown in FIG. 6). Figure 9 As shown in FIG. 6, the driving rod 63 is aligned with the sealing sleeve 30; after the asphalt pavement is heated and softened, the driving element 61 continues to drive the driving rod 63 to move downward, the driving rod 63 pushes the sealing sleeve 30, so that the sealing sleeve 30 is inserted into the asphalt pavement (for example, as shown in FIG. 6).

[0080] After the detection is completed, the driving element 61 drives the driving rod 63 to move upward, at this time, the driving rod 63 is still attracted by the first magnet 65, and the connection with the sealing sleeve 30 is maintained, so that the driving rod 63 drives the sealing sleeve 30 to move upward, and there is a certain friction between the guide needle 42 and the sealing sleeve 30, so that the guide needle 42 moves upward synchronously with the sealing sleeve 30 until the sealing sleeve 30 is reset, at this time, the limiting plate 66 abuts against the mounting plate 22 to prevent the sealing sleeve 30 from continuing to move upward; the driving rod 63 continues to move upward under the driving of the driving element 61 until the driving rod 63 is separated from the first magnet 65, and is reset under the pulling force of the elastic element 64 to be aligned with the connecting frame 41 again.

[0081] In this way, the guide needle 42 and the sealing sleeve 30 can be automatically driven in sequence by one driving element 61 to insert into the pavement and reset, which effectively reduces the number of driving elements 61 and effectively prevents incorrect operation, for example, driving the sealing sleeve 30 to move downward without inserting the guide needle into the heated pavement.

[0082] As shown in FIG. 6, the driving element 61 drives the driving rod 63 to move downward, the driving rod 63 abuts against the connecting frame 41 and pushes downward, so that the guide needle 42 is inserted into the asphalt pavement, and after the guide needle 42 is inserted into the asphalt pavement to a preset depth (set according to actual requirements), the driving rod 63 coincides with the first magnet 65 in the height direction by a certain size (for example, as shown in FIG. 6). Figure 1 and Figure 2 As shown in FIG. 6, the driving element 61 drives the driving rod 63 to move downward, the driving rod 63 abuts against the connecting frame 41 and pushes downward, so that the guide needle 42 is inserted into the asphalt pavement, and after the guide needle 42 is inserted into the asphalt pavement to a preset depth (set according to actual requirements), the driving rod 63 coincides with the first magnet 65 in the height direction by a certain size (for example, as shown in FIG. 6).

[0083] It should be noted that in the process of driving rod 63 pushing connecting frame 41 and guide needle 42 downward, the lower end of driving rod 63 (i.e. the lower end of second magnet 631) just coincides with the upper end of first magnet 65 in the height direction, at this time, guide needle 42 has not been inserted to the preset depth; and since second magnet 631 is fixed at the lower end of driving rod 63, and the magnetic poles at the upper and lower ends are opposite to the magnetic poles of first magnet 65, at this time, the magnetic pole of the lower end of driving rod 63 (i.e. the lower end of second magnet 631) is the same as the magnetic pole of the upper end of first magnet 65, repulsive force is formed, and thus it is effectively avoided that first magnet 65 attracts driving rod 63 when guide needle 42 has not been inserted to the preset depth.

[0084] After guide needle 42 is inserted to the preset depth, second magnet 631 is lowered to overlap first magnet 65 by more than half the height of first magnet 65 (as shown in Figure 6 and Figure 8 , the magnetic poles of the two are opposite and attractive force is generated, and thus the attractive force can be effectively increased, and it is ensured that driving rod 63 can be attracted.

[0085] As shown in Figure 1 and Figure 2 , in one specific embodiment of the expressway water seepage detection device provided by the embodiment of the application, the upper side of connecting frame 41 is an upper convex arc surface, which can effectively reduce the contact area of driving rod 63 and connecting frame 41, and thus reduce the friction force, and further make driving rod 63 easily be attracted by first magnet 65 and switched to the second state.

[0086] The above only describes the preferred embodiments of the application and is not used to limit the application, and any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the application.
