Manhole cover detection and positioning device

The present invention relates to a positioning device, and more particularly to a manhole cover detecting and positioning device.

Referring to Figure 1, the current manhole cover 11 is usually placed on the road surface to close a pipe 12 leading to the ground. However, when laying asphalt concrete on the road surface, it is often caused by the manhole cover 11 protruding from the road surface. The unevenness of the pavement will not only affect the aesthetics, but also cause the traffic vehicle to oscillate up and down during driving, which will affect the comfort and even hinder the driving and cause traffic accidents.

Referring to FIG. 2, the road level project is started everywhere, and the portion 12A of the pipe 12 below the manhole cover 11 near the road surface is enlarged to be larger than the manhole cover 11, and then the manhole cover 11 is moved down to the road surface. At the position of 25 to 30 cm, the top of the manhole cover 11 is finally refilled with the filler 13 so that the pavement can be prevented from being affected by the protrusion of the manhole cover 11 when the road surface is laid, thereby keeping the road surface flat. However, the foregoing method will bury the manhole cover 11 under the unobstructed road surface. Therefore, in the subsequent refurbishment of the pipe 12, it is necessary to try to locate the position of the manhole cover 11, and then place the pavement and After the filler 13 is dug, the manhole cover 11 is exposed, and finally the manhole cover 11 is taken out and the lower pipe 12 is constructed.

The invention patent of the Republic of China Publication No. I398567 proposes a method of detecting the manhole cover 11 located under the road surface on the road surface by using a metal detector to make the characteristics of the metal cover 11, but this method is difficult. The disadvantages of measurement, time consuming and large errors. Therefore, the new patent case No. M507942 of the Republic of China Announcement proposes that two Radio Frequency Identification (RFID) modules are disposed on the top surface of the manhole cover 11 and are located on the diagonal. Then, the signal of the radio frequency identification module is detected on the ground, and the center point of the manhole cover 11 is estimated through the measured two sets of signals, thereby achieving the positioning effect. However, the signal of the radio frequency identification is easy to diverge in the process of upward transmission. Therefore, even if two radio frequency identification modules are set, the two sets of signals emitted by the radio frequency identification chip will still be diverged due to the signal, and the accuracy is lowered.

Therefore, the purpose of the present invention is to provide an accurate manhole cover detecting and positioning device.

Therefore, the manhole cover detecting and positioning device comprises a reinforced concrete structure, a substrate, a receiving seat, an inner plug cover, a protective cover, and a detecting component.

Referring to FIG. 5, FIG. 6, and FIG. 7, the installation method of the embodiment includes a descending step 31, a setting step 32, and a laying step 33.

This embodiment is applicable to a manhole cover 41 which is disposed on a road surface and has a duct 40 opened below. In the lowering step 31, the pipe 40 is widened from the road surface to 25 cm below the road surface, so that the manhole cover 41 can be lowered to 25 cm below the road surface, and it is particularly necessary to avoid opening the manhole. When the cover 41 is closed, the sand of the outer wall of the widened pipe 40A falls into the unexpanded pipe 40, so that the outer wall of the widened pipe 40A leaves a clearance with the manhole cover 41. In the present embodiment, the widened pipe 40A The length and width are approximately 1600 mm. Referring to FIG. 5, FIG. 6, and FIG. 8, in the setting step 32, the area around the manhole cover 41 is first compacted, and then a layer of about 2 mm is laid on the top surface of the manhole cover 41, and the area is approximately equal to a foam pad 42 having a top surface area of the manhole cover 41, and the manhole cover detecting and positioning device 2 is placed on the cushion 42 for isolating the manhole cover 41 and the The reinforced concrete structure 20 is reinforced and serves to protect the manhole cover 41. At this time, the reinforced concrete structure 20 is spaced apart from the outer wall of the widened pipe 40A. In the present embodiment, the interval is about 50 to 100 mm.

Referring to FIG. 5, FIG. 6, and FIG. 9, in the laying step 33, a release film 43 made of acrylic or plastic is sleeved on the protective cover 24 and covered in the reinforced concrete structure 20 surface. The isolating film 43 is a square having a side length of 200 mm and an area equal to the plate body portion 211, and an opening 431 having a diameter of 97 mm is opened at the center thereof, and the opening 431 is smaller than the maximum outer diameter of the protective cover 24, but Since the spacer film 43 has plasticity, it can still be sleeved on the protective cover 24. When the separation film 43 is sleeved on the protective cover 24, the projected area thereof is coincident with the substrate 21, that is, directly above the substrate 21, and finally asphalt oil is applied to the place other than the release film 43, and A layer of asphalt concrete layer 44 is laid to cover the gap between the reinforced concrete structure 20 and the outer wall of the pipe 40, and is flush with the road surface after tamping and leveling. In this embodiment, the length, width, and height of the asphalt concrete layer 44 are 1600 mm, 1600 mm, and 100 mm, respectively, and the separation film 43 is located between the reinforced concrete structure 20 and the asphalt concrete layer 44 to avoid The reinforced concrete structure 20 and the asphalt concrete layer 44 are mixed. The manhole cover detecting and positioning device 2 can be disposed on the manhole cover 41 by the foregoing steps, and the manhole cover 41 is placed under the road surface to avoid affecting the road surface flatness. Since the body portion 222 of the receiving base 22 is made of metal, the signal emitted by the detecting component 25 disposed in the lower portion 222 of the lower portion is blocked by the body portion 222, and the detecting component The upper section of 25 is located in a protective cover 24 made of plastic material, so that the signal can be transmitted upward and outward through the protective cover 24, thereby reducing the signal divergence and facilitating detection of the detective on the road surface. Measuring element 25.

Referring to FIG. 5 and FIG. 10 , the construction method of the present embodiment includes a detecting step 51 , a sampling step 52 , a marking step 53 , a cutting step 54 , a lifting step 55 , and a back filling step 56 .

In the detecting step 51, the signal emitted by the detecting component 25 is detected by a marker (not shown) on the road surface, and the center position of the manhole cover detecting and positioning device 2 is located. Referring to FIG. 5, FIG. 10 and FIG. 11, in the sampling step 52, the asphalt concrete layer 44 is drilled and sampled by the driller from the road surface to take out the detection and positioning of the manhole cover detected by the foregoing. The cylindrical block 45 having a diameter of about 150 mm and a height of about 100 mm calculated from the center position of the device 2, since the reinforced concrete structure 20 has a lower viscosity than the asphalt concrete layer 44, when the cylindrical block 45 is removed, The protective cover 24 is taken out together to expose the receiving seat 22. The detecting element 25 is then taken out.

Referring to FIG. 10, FIG. 11, and FIG. 12, in the marking step 53, a jig 61 surrounding a through groove 60 is sleeved on the top end of the receiving seat 22, and an extending seat 62 is inserted into the jig. In the through groove 60 of the 61, after the assembly, the receiving seat 22, the jig 61, and the central axis of the extending seat 62 are located on the same extension line. Then, a square template 63 having a length of 1400 mm is sleeved on the extension seat 62 and placed on the un-drilled asphalt concrete layer 44. The template 63 generally cuts a plurality of slots according to the distance (not shown). Therefore, the constructor can mark directly along the slot of the template 63 to mark the boundary of the reinforced concrete structure 20 and the asphalt concrete layer 44. In the present embodiment, the area indicated is a square having a side length of 1200 mm to 1300 mm.

Referring to FIG. 10, FIG. 12, and FIG. 13, in the cutting step 54, the reinforced concrete structure 20 and the asphalt concrete layer 44 are cut along the markings drawn in the marking step 53, and the template 63 is removed. The extension seat 62, the jig 61, and the inner cover 23 prevent the blind hole 221 from being closed. In the present embodiment, the cutting depth is 300 mm, and the cutting line can be visually observed on the road surface.

Referring to FIG. 5, FIG. 10, and FIG. 14, in the lifting step 55, a lifting screw 64 having a lifting ring 641 is locked on the thread 223 of the receiving seat 22, and the lifting device is used. The lifting screw 64 is lifted together with the manhole cover detecting and positioning device 2 (including the reinforced concrete structure 20) and the asphalt concrete layer 44 to expose the cushion 42. After the cushion 42 and the manhole cover 41 are removed, the worker can repair or construct the pipe 40.

Referring to FIG. 5, FIG. 10, and FIG. 15, in the backfilling step 56, the suspended manhole cover detecting and positioning device 2 and the asphalt concrete layer 44 are backfilled to make up the gap. Then, the inner cap 23 is locked into the thread 223 to reclose the blind hole 221, and the detecting component 25 is repositioned into the receiving groove 234, and the cylindrical region taken out in the sampling step 52 is removed. The block 45 is backfilled, and the protective cover 24 is placed on the receiving seat 22, and the gap is restored by the adhesive to restore the just installed state. In the present embodiment, the adhesive used was "sticky" (product type MS-R301) produced by RETEK.

It should be specially noted that the cutting line generated in the cutting step 54 can be visually confirmed on the road surface. Therefore, when the manhole cover 41 is to be opened next time, it is not necessary to re-detect the RFID signal and directly search for the cutting line. The cutting step 54 and the lifting step 55 can be performed to effectively improve the convenience, and in addition, the marking can be reinforced at the cutting portion so that the constructor can easily recognize it.

In summary, the metal housing 20 can reduce the divergence of the signal of the detecting component 25, thereby effectively improving the positioning accuracy. In addition, the manhole cover 41 can be opened by the above construction method to construct the pipe 40 below, so that the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
