Description

Technical Field

[0001] The invention relates to the technical field of engineering detection, in particular to a tunnel ditch construction quality detection device. Background Art

[0002] In urban construction, in order to reduce the distance and keep the road unobstructed, it is often necessary to open tunnels. In tunnel construction, it is usually necessary to open side ditches on both sides of the tunnel. Tunnel side ditches are designed and built for drainage. They usually appear in the form of a ditch extending along the side of the tunnel. Their function is to collect and guide precipitation and prevent rainwater from accumulating around the tunnel and forming flooding. Tunnel side ditches can not only protect the environment around the tunnel, but also help maintain safe passage of the road.

[0003] The design and construction of tunnel ditches take into account factors such as longitudinal slope, water volume, flow rate, etc. to ensure that they have good drainage effects. Drainage ditches are usually set up on both sides of the tunnel to guide the collected water to the outside of the tunnel for drainage. The construction quality inspection of tunnel ditches is an important part of ensuring its function and safety. The inspection usually includes an assessment of the stability of the ditch structure, drainage effect, material quality, etc. In addition, project acceptance is also required to ensure that the construction meets relevant standards and specifications.

For example, if the error range is set to +-2 cm, the first push rod 150 is 2 cm away from the contact pieces b on both sides thereof. When the first push rod 150 swings left and right within 2 cm, the contact piece a will not contact the contact piece b, so that when the first push rod 150 swings within the error range, the device will not generate an alarm.

[0052] In this embodiment: when the detection vehicle 110 is driving, when the width detection rod 140 moves to the narrowed part of the side ditch body 100, the width detection rod 140 drives the first push rod 150 to move to the left side, until the first push rod 150 moves to the left side beyond the allowable error range, and then the first push rod 150 pushes the contact piece a201 in the first warning component 200 to contact the contact piece b202, so that the contact piece a201, the contact piece b202 and the first warning light 207 form a complete circuit loop, so that the first warning light 207 lights up to warn, and at the same time, the contact piece b202 drives the first pointer 208 to move on the width detection table 230, thereby indicating the value of the narrowing of the side ditch body 100 here, and not only that, the contact piece a201 drives the first marking pen 221 to draw a line on the left side of the narrowed side ditch body 100 for marking;

[0053] Similarly: when the width detection rod 140 moves to the point where the width of the ditch body 100 exceeds the allowable error range, the width detection rod 140 drives the first push rod 150 to move to the right, so that the contact piece a201 in the second warning component 210 contacts the contact piece b202, thereby causing the second warning light 2101 to light up and warn. At the same time, the second pointer 2102 indicates the value of the widening of the ditch body 100 on the width detection table 230, and the second marking pen 223 draws a line on the right side of the widened ditch body 100 to mark it; when the height detection rod 170 moves to the point where the width of the ditch body 100 exceeds the allowable error range, the width detection rod 140 drives the first push rod 150 to move to the right, so that the contact piece a201 in the second warning component 210 contacts the contact piece b202, thereby causing the second warning light 2101 to light up and warn. At the same time, the second pointer 2102 indicates the value of the widening of the ditch body 100 on the width detection table 230, and the second marking pen 223 draws a line on the right side of the widened ditch body 100 to mark it; When the body 100 shortens beyond the allowable error range, the third warning light 2111 lights up to warn, and the third pointer 2112 indicates the value of the shortening of the side ditch body 100 at this location on the height detection gauge 231; when the height detection rod 170 moves to the point where the side ditch body 100 increases beyond the allowable error range, the fourth warning light 2121 lights up to warn, and the fourth pointer 2122 indicates the value of the increase of the side ditch body 100 at this location on the height detection gauge 231, which is convenient for intuitively displaying the degree of change in the width and depth of the side ditch body 100, thereby further improving the use effect of the device.

[0054] Embodiment 3: This embodiment is intended to promote the solution of the problem that the device is not convenient for detecting the gutter bodies 100 of different widths and depths, thereby reducing the adaptability of the device. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Fig.11An adjusting assembly 240 is provided on the side of the first push rod 150, and the adjusting assembly 240 includes an adjusting rod 241 fixedly installed on the outside of the first push rod 150, a lever 242 rotatably arranged on the side of the adjusting rod 241, a volute spring 243 installed between the adjusting rod 241 and the lever 242, a latch 244 fixedly connected to the end of the lever 242, and a slot 245 opened on the side of the width detection rod 140; the slots 245 are evenly arranged in a plurality, the latch 244 is inserted into one of the slots 245, and the adjusting rod 241 and the lever 242 are both inserted on the side of the detection vehicle 110; similarly: an adjusting assembly 240 is also provided on the side of the second push rod 190.

[0055] In this embodiment, the first positioning bolt 193 is loosened, and the adjusting rod 241 is held by hand so that the adjusting rod 241 and the first push rod 150 remain stationary relative to the detection vehicle 110. At the same time, the lever 242 is pressed down so that the latch 244 is pulled out of the slot 245, and the spiral spring 243 is compressed. Subsequently, the width detection rod 140 is pulled outward or pushed inward according to the width of the side ditch body 100, so that the width detection rod 140 drives the first sleeve 192 to be pulled outward or pushed inward, and the end of the width detection rod 140 still contacts the side ditch body. On the inner wall of 100, release the lever 242, and under the action of the rebound force of the spiral spring 243, drive the lever 242 to rotate and reset, use the pin 244 to insert into the corresponding slot 245, and finally, tighten the first positioning bolt 193 to complete the adjustment of the device to the detection width of the ditch body 100; similarly, through the above operations, the adjustment of the device to the detection depth of the ditch body 100 is completed, so that the device is convenient for detecting ditch bodies 100 of different widths and depths, thereby improving the adaptability of the device.

[0056] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
