Description

Technical Field

[0001] This invention relates to the technical field of anchor drilling simulation, and more particularly to an anchor drilling installation device and installation method. Background Technology

[0002] Anchor bolt support is widely used in geotechnical engineering. To ensure that anchor bolt support is economical, safe and effective, testing its support performance is very important.

[0003] Due to the high cost and long time required for field tests of anchor support performance, many scholars at home and abroad have turned their attention to indoor tests. Currently, most fields related to anchor support performance testing are limited to testing the mechanical properties of individual anchors, rarely taking into account the interaction between the anchor and the surrounding rock mass, resulting in poor simulation results that are close to reality.

[0004] Therefore, in order to conduct in-depth research on the anchoring performance of anchor bolts in surrounding rock, it is urgent to design a device that combines surrounding rock simulation and anchor bolt drilling and installation to serve the laboratory test of anchor bolt support performance. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an anchor bolt drilling and installation device and installation method, which solves the technical problem that the simulation of anchor bolt support in the prior art has poor resemblance to the actual situation.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0009] In a first aspect, embodiments of the present invention provide an anchor drilling and installation device, including a drilling platform, a simulation mold, and a pouring device. The simulation mold is disposed on the drilling platform, and the pouring device is disposed at both ends of the simulation mold. The drilling platform is used to provide support for the simulation mold, the simulation mold is used to pour concrete to realize the function of simulating the surrounding rock mass, and the pouring device is used to assist the simulation mold in completing the concrete pouring operation.

[0010] In this technical solution, the anchor bolt drilling and installation device includes a drilling platform, a simulation mold, and a casting device. The drilling platform serves as the installation base for the simulation mold. Firstly, the drilling platform can provide support for the simulation mold. Secondly, the drilling platform has a certain height, which allows the simulation mold to also have a certain height, thus facilitating the anchor bolt drilling work.

[0011] The simulation mold is used to pour concrete, and the pouring device exists as an auxiliary device for concrete pouring; in other words, it can serve as an input port for concrete.

[0012] In this invention, because concrete can be placed inside the simulation mold to simulate the surrounding rock, and the simulation mold is set on the drilling platform, the simulation mold has good flexibility and can carry out corresponding simulation work indoors to realize the simulation function of the surrounding rock required for anchor drilling and installation. This fully reflects the anchoring effect between the anchor to be tested and the surrounding rock, improves the scene reproduction of the indoor test of anchor support performance compared with the field test, and can improve the reliability of the anchor support performance test results to a certain extent.

[0013] In one technical solution of the present invention, the simulated mold includes multiple sub-molds and fasteners. The multiple sub-molds are interlocked to form a cavity with a hollow center. The fasteners are used to connect the multiple sub-molds. The casting device can communicate with the cavity.

[0014] In this technical solution, the simulated mold includes multiple sub-molds and fasteners. The sub-molds interlock to form a cavity, which contains a hollow space that serves as a storage cavity for concrete. The fasteners act as fastening components for the sub-molds, used to define the positions between different sub-molds.

[0015] Specifically, there can be two sub-molds, both of which are symmetrical semi-cylindrical shell structures. Correspondingly, fasteners are used to fasten the two semi-cylindrical shell structures together.

[0016] The pouring device is connected to the cavity, allowing concrete to enter the cavity from the outside and complete the pouring, thus simulating the surrounding rock mass.

[0017] Specifically, the casting device can be positioned at both ends of two symmetrical semi-cylindrical shell structures.

[0018] In one technical solution of the present invention, a first connecting ear extends from the sub-mold, the plane of the first connecting ear is perpendicular to the axis of the simulated mold, and a first connecting body is formed corresponding to multiple first connecting ears, and fasteners are correspondingly fastened to the first connecting body;

[0019] The fastener has a connecting groove, which is engaged with the first connecting body. The fastener and the first connecting body are locked together by a locking member. Multiple fasteners are used to form a second connecting body, which is located on the periphery of the first connecting body.

[0020] In this technical solution, a first connecting ear extends from the sub-mold, and the plane of the first connecting ear is perpendicular to the axis of the simulated mold. That is, the first connecting ear extends along the radial section of the simulated mold. The fastener is used to lock the first connecting ear. Specifically, on the two semi-cylindrical shell structures, two corresponding first connecting ears form a first connecting body, and two fasteners form a second connecting body. The corresponding first connecting bodies are fastened through the second connecting body, so that the position of the two first connecting ears in the first connecting body is defined. With the fastening action of multiple sets of first connecting bodies and second connecting bodies, the sub-mold can be fastened.

[0021] To ensure the reliability of the connection between the first connector and the second connector, a connecting groove can be made on the fastener so that the connecting groove and the first connector can be locked by a locking element, which can be a bolt.

[0022] In one technical solution of the present invention, a second connecting ear extends from the sub-mold, the second connecting ear being parallel to the longitudinal plane where the axis of the simulated mold is located, and is connected to the corresponding second connecting ear.

[0023] In this technical solution, a second connecting ear extends from the sub-mold. When the sub-mold is two symmetrical semi-cylindrical shell-shaped structures, the second connecting ear is correspondingly set on the two sub-molds. The second connecting ear at the outer position can be detachably connected by bolts. With the connection function of the fastener, the reliability and stability of the connection between the sub-molds can be further improved.

[0024] In one technical solution of the present invention, the simulation mold further includes anti-slip ribs, which are disposed on the inner wall of the cavity; wherein, the anti-slip ribs can prevent relative displacement between the concrete filled into the cavity and the cavity.

[0025] In this technical solution, the simulation mold also includes anti-slip ribs. The anti-slip ribs are located on the inner wall of the cavity. The anti-slip ribs can extend along the radial section of the simulation mold and are distributed in parallel on the inner wall of the cavity. They can provide sliding constraints for the concrete after it is filled into the simulation mold, preventing relative sliding between the concrete and the cavity after the concrete has been poured and solidified, thereby preventing the concrete from falling out of the cavity.

[0026] In one technical solution of the present invention, the drilling platform includes a support frame, an installation platform and multiple connecting frames. The installation platform is located on top of the support frame, and the multiple connecting frames are located on the installation platform. An installation space is formed between the connecting frames and the installation platform. A simulated mold is located in the installation space, and the connecting frames are matched with fasteners. The connecting frame includes a limiting body and a cover. The limiting body is located on the installation platform and is matched with a second connecting body. The cover is detachably located on the limiting body.

[0027] In this technical solution, the drilling platform includes a support frame, an installation platform, and multiple connecting frames, with the simulated mold confined on the installation platform by the connecting frames.

[0028] Specifically, the support frame includes a top plate, a bottom plate, a front frame, a rear frame, and a middle support. The top plate and the bottom plate are fixedly connected by bolts through the middle support, and the front frame and the rear frame are fixedly connected to the top plate and the bottom plate by bolts.

[0029] Furthermore, the top plate includes a top flat steel plate and a top plate angle steel plate. The connecting frame includes a limiting body and a buckle cover. The top flat steel plate is a rectangular plate structure with widened flanges, and the flanges have holes and protruding buckles. The top plate angle steel plate has bolt holes on one side and is fixed to the lower surface of the top plate. The limiting body is a right-angled triangular support structure, fixed to the upper surface of the flat steel plate on one side, and multiple limiting bodies can be installed. The buckle cover is a cubic shell structure, which can have four fixing legs, and the fixing legs have bolt holes at the ends, which can be inserted into the holes provided in the flat steel plate and bolted to the buckle cover.

[0030] The base plate includes a base plate steel plate, a base plate angle steel plate, and casters; the base plate steel plate is a rectangular plate structure; the base plate angle steel plate has bolt holes on one side and is fixed to the upper surface of the base plate; the casters are 360° rotatable in the horizontal direction and are fixed to the lower surface of the base plate vertically.

[0031] The front frame is a trapezoidal angle steel structure with a horizontal support platform at the top, and the support platform has locking buckles and bolt holes.

[0032] The rear end frame is a trapezoidal angle steel structure. The inner upper bottom is provided with a horizontal support platform, which is equipped with locking buckles and bolt holes. The outer upper and lower bottoms are also provided with locking buckles and bolt holes.

[0033] The central support is an M-shaped angle steel structure with bolt holes at the ends.

[0034] More specifically, the top plate steel can be used as the installation platform for the drilling platform.

[0035] An installation space is formed between the connecting frame and the installation platform. The simulated mold is placed in the installation space and the connecting frame and fastener match, so that the fastener part of the simulated mold can be fastened by the connecting frame. After fastening, the position of the fastener relative to the installation platform can be defined.

[0036] Specifically, the connecting frame can be installed longitudinally on the mounting platform and locked with bolts. The legs of the connecting frame are used to limit the position of the fasteners on both sides, thereby limiting the position of the fasteners relative to the connecting frame and the mounting platform.

[0037] In one technical solution of the present invention, the casting device includes a top cover and a bottom cover, which are detachably disposed at both ends of the simulation mold, and the top cover is provided with a casting hole.

[0038] In this technical solution, the pouring device includes a top cover and a bottom cover, which are respectively set at both ends of the simulation mold and can be detachably connected to the simulation mold by means of bolts. The bottom cover is a sealing cover, while the top cover has a pouring hole, which provides the hardware foundation for the concrete to be poured into the simulation mold.

[0039] In one technical solution of the present invention, the pouring device further includes a perforated pipe, and a perforated pipe hole is opened on the top cover. The perforated pipe is detachably connected to the bottom cover and extends from the perforated pipe hole to the outside of the pouring device; wherein, the perforated pipe can reserve space for anchor holes in the concrete.

[0040] In this technical solution, the casting device also includes a perforated pipe, through which the perforated pipe passes. One end of the perforated pipe can be set on the bottom cover in the form of a threaded connection, that is, a threaded pin can be set on the bottom cover, and the perforated pipe is threadedly connected to the threaded pin.

[0041] Because of the presence of the perforated pipe, anchor holes can be pre-reserved during concrete pouring. After the concrete has solidified, the perforated pipe can be pulled out to facilitate the installation of anchor bolts.

[0042] Specifically, the perforated pipe can be made of rubber and its surface has a smooth structure to avoid excessive bonding force between it and the concrete.

[0043] To facilitate the disassembly of the perforated pipe, the top and bottom covers can be removed during the disassembly operation.

[0044] Secondly, the present invention provides an installation method for an anchor bolt drilling and installation device, applicable to such an anchor bolt drilling and installation device, the installation method comprising:

[0045] Once the anchor drilling and installation device is assembled, move it to an open area.

[0046] The anchor drilling and installation device was moved to an open area, and concrete was poured into the simulated mold. The concrete was then allowed to solidify.

[0047] Once the concrete has solidified, the anchor bolt installation work will proceed.

[0048] In this technical solution, the installation method of the anchor bolt drilling and installation device includes the assembly process of the anchor bolt drilling and installation device. After assembly, it needs to be moved to an open area to carry out the corresponding anchor bolt driving simulation operation. Then, concrete is poured into the simulation mold. The pouring process is fully vibrated. The pouring is completed when the concrete reaches the top cover. After the concrete solidifies, the corresponding anchor bolt driving operation is performed. Since the simulation mold effectively simulates the surrounding rock mass, it can fully reflect the anchoring effect between the anchor bolt to be tested and the surrounding rock, improve the scene reproduction of the indoor test of anchor bolt support performance compared with the field test, and can improve the reliability of the anchor bolt support performance test results to a certain extent.

[0049] In one technical solution of the present invention, the anchor bolt driving operation specifically includes:

[0050] Remove the top and bottom covers;

[0051] Determine whether the pouring device includes a perforated pipe and whether the top cover has a perforated pipe hole;

[0052] If so, remove the pre-drilled pipe to expose the anchor hole;

[0053] If not; control the drilling rig to perform anchor hole drilling operations on the solidified concrete;

[0054] Perform anchor bolt installation.

[0055] In this technical solution, when performing the anchor bolt installation, the top and bottom covers must first be removed to expose the concrete. Then, it is determined whether a perforated pipe is installed in the building structure and whether a perforated pipe hole is opened on the top cover. If no perforated pipe or perforated pipe hole is found, it is determined that no anchor hole is pre-reserved in the concrete. In this case, the anchor hole installation operation needs to be performed before the anchor bolt can be installed in the anchor hole. If a perforated pipe or perforated pipe hole is found, it is determined that an anchor hole is pre-reserved in the concrete. In this case, the perforated pipe needs to be removed to expose the anchor hole, and the anchor bolt installation operation can be performed directly without performing the anchor hole installation operation.

[0056] (III) Beneficial Effects

[0057] The beneficial effects of the present invention are as follows: The anchor drilling and installation device and method of the present invention can simulate the surrounding rock by setting concrete inside the simulation mold. At the same time, the simulation mold is set on the drilling platform, which makes the simulation mold more flexible and can carry out the corresponding simulation work indoors. Therefore, it can realize the simulation function of the surrounding rock required for anchor drilling and installation, fully reflect the anchoring effect between the anchor to be tested and the surrounding rock, improve the scene reproduction of the indoor test of anchor support performance compared with the field test, and can improve the reliability of the anchor support performance test results to a certain extent.

[0058] Compared with existing technologies that simulate the practical working conditions of anchor bolts through mechanical performance testing, this invention not only retains the mechanical performance testing of anchor bolts, but also enables stress simulation of anchor bolts within concrete, which closely resembles the surrounding rock environment. Therefore, this device improves the simulation of anchor bolt working conditions, thus providing a hardware foundation for more comprehensive analysis and testing of anchor bolts.

One end of the perforated pipe 33 can be set on the bottom cover 32 in the form of a threaded connection, that is, a threaded pin can be set on the bottom cover 32, and the perforated pipe 33 is threadedly connected to the threaded pin.

[0143] Because of the presence of the perforated pipe 33, anchor holes can be pre-reserved during concrete pouring. After the concrete has solidified, the perforated pipe 33 can be pulled out to facilitate the installation of anchor bolts.

[0144] Specifically, the perforated pipe 33 can be made of rubber and its surface has a smooth structure to avoid excessive bonding force between it and the concrete.

[0145] To facilitate the disassembly of the perforated tube 33, the top cover 31 and the bottom cover 32 can be removed during the disassembly operation of the perforated tube 33.

[0146] Example 5:

[0147] Reference Figure 9 and Figure 10Another aspect of the present invention provides an installation method for an anchor bolt drilling and installation device, applicable to such an anchor bolt drilling and installation device. The installation method for the anchor bolt drilling and installation device includes:

[0148] S1: Once the anchor drilling and installation device is assembled, move it to an open area;

[0149] S2: Move the anchor drilling and installation device to an open area, pour concrete into the simulation mold 2, and wait for the concrete to solidify;

[0150] S3: Once the concrete has solidified, proceed with the anchor bolt installation.

[0151] In this embodiment, the installation method of the anchor drilling and installation device includes the assembly process of the anchor drilling and installation device. After assembly, it needs to be moved to an open area to carry out the corresponding anchor drilling simulation operation. Then, concrete is poured into the simulation mold 2. The pouring process is fully vibrated. The pouring is completed when the concrete reaches the top cover 31. After the concrete solidifies, the corresponding anchor drilling operation is performed. Since the simulation mold 2 effectively simulates the surrounding rock mass, it can fully reflect the anchoring effect between the anchor to be tested and the surrounding rock, improve the scene reproduction of the indoor test of anchor support performance compared with the field test, and can improve the reliability of the anchor support performance test results to a certain extent.

[0152] In this embodiment, the anchor bolt installation operation specifically includes:

[0153] S3.1: Remove the top cover 31 and the bottom cover 32;

[0154] S3.2: Determine whether the pouring device 3 includes a perforated pipe 33, and whether a perforated pipe hole G is provided on the top cover 31;

[0155] S3.3.1: If so, remove the hole-holding tube 33 to expose the anchor hole;

[0156] S3.3.2: If not; control the drilling rig to perform anchor hole drilling operations on solidified concrete;

[0157] S3.4: Perform anchor bolt installation.

[0158] In this embodiment, when performing the anchor bolt installation, the top cover 31 and bottom cover 32 are first removed to expose the concrete. Then, it is determined whether a perforated pipe 33 is installed in the building structure and whether a perforated pipe hole G is opened on the top cover 31. If there is no perforated pipe 33 or perforated pipe hole G, it is determined that no anchor hole is pre-reserved in the concrete. In this case, the anchor hole installation operation needs to be performed before the anchor bolt can be installed in the anchor hole. If there is a perforated pipe 33 and perforated pipe hole G, it is determined that an anchor hole has been pre-reserved in the concrete. In this case, the perforated pipe 33 is removed to expose the anchor hole, and the anchor hole installation operation is not required. The anchor bolt installation operation can be performed directly.
