Description

Technical Field

[0001] This utility model is a protective device for the opening of a long observation hole, belonging to the field of water conservancy and hydropower engineering. Background Technology

[0002] Long-term observation boreholes are widely used in geotechnical engineering and hydropower engineering. They are an important means of observing seepage, deformation, cracks and other internal features of rock, soil and buildings. In the field of water conservancy and hydropower engineering, long-term observation boreholes are mainly divided into acoustic wave testing long-term observation boreholes and hydrogeological testing long-term observation boreholes, which are used for acoustic wave velocity testing of engineering rock masses and hydrogeological observation of engineering sites, respectively.

[0003] Observation holes are generally quite deep and have a small diameter. During the use of long observation holes, particles such as stones and gravel can easily enter the hole and block the opening. At the same time, during the testing of long observation holes, the measuring rope and data cable directly rub against the rock at the opening during the raising and lowering of the testing device, causing great wear and tear. This not only affects the hole wall but also easily damages the measuring rope and data cable. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a protective device for the orifice of a long observation hole, so as to solve the problems mentioned in the background art, such as the easy entry of pebbles, gravel and other particles into the hole and clogging the orifice, and the extreme wear caused by the direct friction between the measuring rope and the data cable and the rock at the orifice.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a long observation hole protection device, comprising a concrete pier, wherein a long observation hole is provided on the top of the concrete pier;

[0006] The top of the concrete pier is provided with a protective mechanism to protect the long observation hole. The protective mechanism includes a fixed base plate, which is placed above the concrete pier. The bottom of the fixed base plate is provided with a protective sleeve, and the top of the protective sleeve is connected to the fixed base plate. The protective sleeve is inserted into the long observation hole.

[0007] Furthermore, each of the four corners of the top of the fixed base plate is provided with a fixing screw hole, and each of the four corners of the top of the fixed base plate is provided with a protective retaining ring groove, and the protective retaining ring groove and the fixing screw hole are coaxially distributed in a one-to-one correspondence.

[0008] Furthermore, the top of the fixed base plate is provided with an assembly base, the top of the assembly base is provided with an assembly cavity, and the assembly cavity is connected to the protective sleeve.

[0009] Furthermore, the assembly base has mounting holes on both sides below, and mating grooves on both sides above, with the bottom of the mating grooves communicating with the mounting holes. A protective top cover is placed on the top of the assembly base.

[0010] Furthermore, both ends of the protective top cover are provided with assembly ear plates, and the bottom of each assembly ear plate is provided with a waterproof sleeve. The bottom of each waterproof sleeve is equipped with a sealing soft rubber ring, and the sealing soft rubber rings are inserted into the protective retaining ring grooves one by one.

[0011] Furthermore, each end of the bottom of the protective top cover is provided with an assembly plate, and an assembly frame is installed between the two ends below the two assembly plates. Guide rods are installed between the two ends inside the bottom cavities of the two assembly frames. Alignment strips are provided on the upper side of one side of each of the two assembly plates, and the alignment strips are inserted into the docking grooves one by one.

[0012] Furthermore, a guide slider is fitted on one end of the outer side of each guide rod, and a push spring is fitted on the other end of each guide rod. The bottom of each guide slider is connected to both ends of the top side of the assembly block, and the assembly blocks are located at both ends of the assembly cavity. The other ends of the two assembly blocks are respectively inserted into the mounting slots, and a positive magnet is embedded in the other ends of the two assembly blocks.

[0013] Furthermore, each of the two card-mounting oral cavities has an array of connecting holes at one end. Each of the two card-mounting oral cavities has a push plate placed on one side, and a negative magnet is embedded in one side of each push plate. The negative magnet and the positive magnet are attracted to each other. Each of the two push plates has an array of assembly posts on the other side. One end of each assembly post passes through the connecting hole and is installed in an array on one side of the two push plates. Each assembly post has a return spring sleeved on its outer side, and the return spring is located between the assembly base and the push plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. The protective mechanism can be used to close the long observation hole when it is not in use, so as to prevent the hole from being blocked by sand and gravel and other impurities during long-term exposure, which would render the long observation hole unusable, affect the hydrological testing of the water conservancy and hydropower project in the later stage, and leave hidden dangers for the safety of the water conservancy and hydropower project.

[0016] 2. The protection mechanism uses waterproof sleeves and sealing soft rubber rings to protect the bolts installed in the fixed screw holes for fixing the device, preventing the bolts from being directly exposed to the outside and corroded and rusted by rainwater, which could damage the installation between the foundation and the bolts and cause the assembly between the device and the foundation to loosen.

[0017] 3. The protection mechanism extends the protective sleeve into the long observation hole, effectively protecting the hole wall, enhancing its stability and compressive strength, and reducing the risk of damage and collapse under various external forces. At the same time, the smooth inner wall of the protective sleeve can prevent the rough hole wall from damaging the measuring rope and data cable. Attached Figure Description
