Description

Technical Field

[0001] This invention belongs to the technical field of concrete molds, specifically a concrete specimen casting mold and method for protecting conductors. Background Technology

[0002] The DC resistivity method is a commonly used method for underground engineering exploration in the field of civil engineering. It has the advantages of simple principle and strong anti-interference ability. It can not only carry out engineering exploration for resource development and underground space development and utilization on a large scale, but also characterize the internal structure of rock masses and other structures on a small scale.

[0003] To apply this technology to concrete structures and understand the internal structure of concrete specimens, the laboratory needs to cast concrete specimens with embedded wires to measure the resistivity of the concrete structure and then use three-dimensional inversion technology to characterize its internal structure. Currently, commonly used concrete molds in the laboratory are difficult to embed wires in; direct embedding or perforation embedding would reduce the smoothness of the concrete surface and the ease of demolding.

[0030] Furthermore, a pull ring 10 is provided on the outer side of the wall panel 2 for pulling the wall panel 2.

[0031] The present invention also provides a method for casting concrete specimens based on a concrete specimen casting mold for a protective conductor, comprising the following steps: Two wall panels 2 are respectively installed on both sides of the main frame 1, and the two ends of the wall panels 2 are slid into the mounting grooves of the side panels respectively; Insert the connecting strip 3 to lock the wall panel 2 and the main frame 1. One of the clips 8 of the connecting strip 3 is inserted into the T-shaped slot 5 of the bottom plate, and the other clip 8 is simultaneously inserted into the T-shaped slot 7 of the wall panel 2 and the corresponding T-shaped slot 6 of the side panel. Insert the wire into the through hole 4 and the conical barrel 12 and extend it into the casting cavity. The conical barrel 12 is installed in the through hole 4. Concrete is poured, and the conical bucket 12 is used to stop the cement slurry from bonding and fixing the wire to the wall panel 2. Wrap the extended portion of the wire around the wire hook post 11; Concrete molding; After the concrete has solidified, the wires wrapped around the wire hook post 11 are unwound, the connecting strip 3 is pulled out and the wall panel 2 is removed, and then the concrete specimen is taken off the main frame 1.

[0032] In one embodiment, both the main frame 1 and the wall panel 2 are made of plastic.

[0033] In one embodiment, a sealing waterproof strip is provided at the connection between the wall panel 2 and the side of the main frame 1.

[0034] In one specific embodiment, a concrete specimen casting mold for facilitating wire laying and providing a sliding protective wire is provided, comprising a main frame 1, wall panels 2, and connecting strips 3. The main frame 1 includes a base plate with a T-shaped slot 5 on a long, narrow face, two short side plates with T-shaped slots 6 on the lower left and right corners, each with a side plate that can be fitted with a connecting strip 3, and two horizontal partitions. The four plates are equally spaced and vertically bonded to the base plate. The wall panel 2 has a through hole 4 and a thick plate with a T-shaped slot 7 on the long, narrow bottom face. The connecting strip 3 is a long strip of floor 9 with a connecting strip welded to two adjacent long, narrow faces. The wall panel 2 and the main frame 1 are slidably fitted together by the connecting strip 3 to form the main body of the mold. A conical barrel 12 is inside the through hole 4 of the wall panel 2, a pull ring 10 is on the outside of the wall panel 2, and wire hook posts 11 are on the front and rear side plates of the main frame 1.

[0035] How to use: The wall panel 2 is inserted into both sides of the main frame 1, and the connecting strip 3 is inserted into the main frame 1 and the wall panel 2 from the lower left and right corners. The bottom plate of the main frame 1 is slidably engaged with the T-shaped locking block 8 of the connecting strip 3 through the T-shaped locking groove 5 of the bottom plate and the T-shaped locking groove 6 of the side plate. The wall panel 2 is slidably engaged with the T-shaped locking block 8 of the connecting strip 3 through the T-shaped locking groove 7 of the wall panel. The three are interlocked, the structure is stable and leak-proof, and constitutes the main part of the mold.

[0036] The conical barrel 12 is inserted into the through hole 4 from the inside of the wall panel 2. The wire passes through the entire mold through the conical barrel 12. The function of the conical barrel is to prevent the wire from sticking to the wall panel due to cement slurry flowing into the round hole, which would cause the wire to break when the wall panel 2 is pulled out.

[0037] After the concrete is poured, the part of the conductor extending out of the mold can be wrapped around the conductor hook post 11 to prevent the conductor from falling off and accidentally affecting the pouring effect.

[0038] When demolding the concrete, first untangle the wire wrapped around the wire hook post 11, pull out the connecting strip 3, then pull the wall panel 2 outward through the pull ring 10, and finally remove the concrete specimen from the main frame 1.
