Description

TECHNICAL FIELD

[0001] The utility model belongs to the municipal traffic survey drilling field, concretely is a kind of municipal road survey drilling temporary hole sealing device. BACKGROUND

[0002] In the process of continuously promoting road reconstruction and extension project, the road geological survey work in the early stage of the project is the key link to ensure the smooth development of the project. Geological survey drilling operation is usually implemented at night, aiming to minimize the interference with daytime road traffic, which results in that these drillings cannot be completely closed during the day. Under this condition, exploring an efficient and safe temporary plugging scheme has become an urgent demand in the current engineering field.

[0003] The temporary plugging means commonly used at present mainly covers the drillings with small-size rectangular steel plates and fixes the periphery thereof with steel nails. However, this method exposes many drawbacks in actual operation. Due to heavy traffic flow and high vehicle speed, the rectangular steel plates are prone to displacement under the impact of vehicles, which seriously weakens the plugging effect and even leads to safety risks. In addition, if the steel nails are not properly disposed after being fixed, they are likely to protrude from the road surface, which directly threatens the safety of tires of passing vehicles and pedestrians and greatly affects the road traffic safety and efficiency. In view of this, it is particularly important to develop a more advanced and reliable temporary plugging technology that can effectively balance traffic smoothness and driving safety. SUMMARY

[0004] To solve the above problems, the utility model provides a kind of municipal road survey drilling temporary hole sealing device, can effectively guarantee the temporary hole sealing quality of municipal road survey drilling process, and guarantee the safety of pedestrian and vehicle passing.

[0005] To achieve the above purposes, the following technical means are specifically adopted in the present application:

[0006] A kind of municipal road survey drilling temporary hole sealing device, including top gland, plugging cylinder body, clamping block, positioning plate, screw rod and conical block;

[0007] The top gland is a circular steel plate with a central hole and a chamfer along the circumferential direction;The plugging cylinder body is a cylindrical steel cylinder with a top through hole, a rectangular through hole and a circular pin hole;The clamping block is a special-shaped steel block with a wider top than bottom, and a steel shaft pin is arranged at the bottom;The positioning plate is a circular steel plate with a central hole;

[0008] The screw rod is a steel screw rod with a hexagonal nut at the top and a thread at the bottom;The conical block is a conical steel block with a threaded through hole in the center and a conical surface.

[0009] Further, the diameter of the top gland is 3 to 4 times the hole diameter, and the thickness is greater than the thickness of the hexagonal nut.

[0010] Further, the card block is connected with the round pin hole of the plugging barrel body through a steel shaft pin, and the inner inclined surface of the card block is in contact with the conical surface of the conical block.

[0011] Further, the screw rod passes through the center hole of the positioning plate, and the screw thread at the bottom of the screw rod is matched with the threaded through hole of the conical block.

[0012] Further, the conical block can move axially along the screw rod, and the card block is pushed to move radially along the plugging barrel body through the conical surface.

[0013] Further, the plugging barrel body and the top gland are connected through welding to form an integral structure.

[0014] Further, the plugging barrel body and the top gland are connected through welding to form an integral structure.

[0015] Through the coordination between the card block and the plugging barrel body and the conical block, the hexagonal nut of the rotating screw rod can easily realize the lifting of the conical block, and then the card block is retracted or expanded, and the operation process is simple and efficient. When the card block is expanded, it can be closely attached to the inner wall of the drill hole, enhancing the fixing effect of the plugging device in the drill hole, preventing displacement due to external forces such as vehicle impact, and ensuring the sealing quality and road safety; the card block is retracted to facilitate the sealing device to be smoothly taken out from the drill hole, avoiding damage to the drill hole and the surrounding road surface, improving the operation convenience and road maintenance efficiency.

[0016] The integral structure formed by welding the plugging barrel body and the top gland greatly enhances the overall strength and stability of the device, effectively resisting the impact force and vibration generated by vehicle driving, preventing displacement of the device, and ensuring that the drill hole is always in a good closed state, effectively ensuring the sealing quality.

[0017] The circular design and circumferential chamfer of the top gland reduce the risk of scratching vehicles and pedestrians compared to traditional rectangular steel plates; and there is no problem of steel nail protrusion, completely avoiding damage to vehicle tires and pedestrians, providing a solid guarantee for the safety and smoothness of road traffic, and significantly improving the traffic safety of the road during the survey period.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific examples. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the explanation of the present invention. The descriptions are merely of preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the scope of protection of the claims.

[0029] Please see Figure 1 The temporary sealing device for borehole drilling in municipal road surveying mainly consists of a top cap 1, a sealing cylinder 2, a locking block 3, a positioning plate 4, a screw 5, and a conical block 6. The top cap 1 is designed as a circular steel plate with a central hole 11 and a chamfered circumference 12 to facilitate the passage of the screw 5 and reduce the risk of scratching. The sealing cylinder 2 is cylindrical, with a top through hole 21, a rectangular through hole 22, and a circular pin hole 23 for subsequent assembly.

[0030] Please see Figure 2 The circular outline and larger diameter of the top cap 1 help enhance the stability of the device covering the borehole. Its thickness is greater than that of the hexagonal nut 51 on the screw 5, ensuring that the screw 5 does not protrude from the surface of the top cap 1 during use.

[0031] Please see Figures 3-5The cylindrical structure of the sealing cylinder 2 has a diameter slightly smaller than the diameter of the sealing hole, making it easier to insert into the borehole. The irregularly shaped design of the locking block 3 allows it to rotate flexibly within the sealing cylinder 2. The steel shaft pin 31 is accurately inserted into the circular pin hole 23, enabling the locking block 3 to retract and extend. The positioning plate 4 is a circular steel plate with a central hole 41 that matches the diameter of the screw 5. During assembly, the screw 5 can smoothly pass through the central hole 41, and the positioning plate 4 provides positioning and support for the screw 5.

[0032] Please see Figure 6 The hexagonal nut 51 at the top facilitates rotation, and the thread 52 at the bottom fits tightly with the threaded through hole 61 of the conical block 6. By rotating the hexagonal nut 51, the conical block 6 can be raised or lowered using the principle of thread transmission.

[0033] Please see Figure 7 and 8 The threaded through hole 61 at the center of the conical block 6 is tightly connected to the thread 52 at the bottom of the screw 5. When the conical surface 62 contacts the locking block 3, it can effectively convert the rotational motion of the screw 5 into the radial movement of the locking block 3.

[0034] Step 1: After assembly, the overall device is an inverted T-shaped cylinder. Before use, use an Allen wrench to rotate the screw and hex nut 51 clockwise so that the screw passes through the positioning plate 4. Through the threaded transmission, the bottom-connected conical block 6 is at its lowest point. The conical block touches the lower part of the symmetrically arranged locking blocks 3 on both sides, causing the locking blocks to rotate along the steel shaft pin 31, and the upper part rotates back into the cylinder.

[0035] Step 2: After placing the sealing device in the borehole to be sealed, operate in the reverse order. Use an Allen wrench to rotate the screw and hexagonal nut 51 in the opposite direction. Through the threaded transmission, the conical block 6 gradually rises, its conical surface contacting the inclined side of the locking block. The conical block pushes the locking block outwards in the direction of the cylinder diameter. The locking block rotates along the steel shaft pin 31, its upper part extending out of the cylinder and abutting against the borehole wall. Continue rotating the screw to make the locking block engage with the surrounding borehole wall to a certain depth, ensuring the sealing device is secure and cannot be pulled out. For subsequent operations, follow Step 1 to easily retract the locking block and remove the sealing device from the borehole.

[0036] After sealing, the drilled hole, covered by the top cap, possesses a certain thickness and rigidity, capable of withstanding a certain load. Its thickness slightly exceeds that of the screw and nut, thus the nut is countersunk, preventing any impact or damage to passing vehicles or pedestrians. The cover plate has a chamfered circumference, further facilitating vehicle passage.

[0037] Those skilled in the art can make appropriate adjustments and improvements to the above embodiments according to the actual situation, but all such adjustments and improvements should be within the scope of protection of the claims of this utility model.
