Referring to fig. 1-4, a preferred embodiment of the present utility model is provided.

The utility model provides a pre-buried interface pipe sealing processing structure suitable for interface drill core detection, which comprises a cover body 200 made of plastic and a pipe body 100 used for interface drill core detection, wherein the cover body 200 is fixedly covered at the bottom of the pipe body 100, a pipe cavity 101 for a drill bit to move up and down is arranged in the pipe body 100, the bottom of the pipe cavity 101 is provided with a bottom opening, and the bottom opening is completely sealed by the cover body 200.

In the above-mentioned pre-buried interface tube sealing processing structure suitable for interface core drilling detection, when core drilling sampling detection is performed, a drill bit is utilized to pass through the tube cavity 101 in the pre-buried tube body 100, and the cover body 200 made of plastic is passed through, so that the tube body 100 can be penetrated for coring; thus, the sealing treatment structure of the interface tube formed by the cover body 200 made of plastic ensures sealing, greatly improves the drilling efficiency of the drill bit and avoids damage of the drill bit.

Example 1, referring to fig. 1:

specifically, the outer periphery of the cover 200 extends upward to form a wrapping ring 210 wrapping the outer periphery of the bottom of the tube 100, and the inner periphery of the wrapping ring 210 is fixedly abutted to the outer periphery of the tube 100 by bonding. In this way, by the design of the packing ring 210 and the adhesion of the packing ring 210 to the outer circumference of the tube body 100, the cover body 200 is stably and permanently fixed to the bottom of the tube body 100.

The bottom of the cover 200 is flat. In this way, when the concrete is poured, the force of the liquid concrete to the cover 200 is kept as uniform as possible, the translocation of the pipe body 100 is avoided, and the installation of the cover 200 is facilitated.

Specifically, the middle part of the cover 200 completely closes the bottom opening; the middle portion of the cap 200 protrudes toward the lumen 101 to form a positioning post 220, and the positioning post 220 is embedded in the lumen 101. Thus, the design of the positioning column 220 facilitates the installation of the cover body 200 and the effective positioning of the cover body 200, so that the whole structure is more compact and stable.

An annular sealing interval is arranged between the positioning column 220 and the wrapping ring 210, a sealing ring 300 is arranged in the sealing interval, and the lower surface of the sealing ring 300 is propped against the cover body 200. In this way, the sealing performance can be improved by the seal ring 300, and the sealing can be ensured.

Specifically, the bottom of the tube body 100 has an annular bottom wall that is pressed against the upper surface of the seal ring 300. Thus, the bottom wall needs to be polished and flattened before being installed, and the bottom wall is pressed against the sealing ring 300 to complete assembly, and fixation is realized through bonding.

The outer circumference of the positioning post 220 has an annular groove formed by being recessed radially inward, the annular groove being circumferentially arranged along the outer circumference of the positioning post 220, and the inner circumference of the sealing ring 300 being embedded in the annular groove. In this way, the fixing of the seal ring 300 is ensured, and the translocation of the seal ring 300 is avoided.

Example 2, referring to fig. 2:

the positioning column 220 is hollow, and a circular hole 221 is formed in the top of the positioning column 220;

when the positioning column 220 is embedded in the lumen 101, the positioning column 220 is elastically bent and deformed toward the circular hole 221 under the pressing of the pipe wall 110 of the pipe body 100. In this way, the dual fixing is achieved by using the deformability of the hollow positioning column 220, and the connection between the cap body 200 and the tube body 100 is reinforced.

Specifically, the circular hole 221 coincides with the axis of the positioning post 220. The circular hole 221 is formed at the center of the cover body 200, and the overall structure is more reasonable, ensuring equal elastic force of each of the force points.

Example 3, see fig. 3-4:

in the present embodiment, the outer periphery of the positioning column 220 is wrapped with an elastic ring 400 having elasticity, and the inner periphery of the elastic ring 400 is fixedly abutted on the outer periphery of the positioning column 220 by bonding;

when the positioning post 220 is inserted into the lumen 101, the elastic ring 400 is elastically deformed under the pressing of the wall 110 of the tube body 100. By fixedly sleeving the elastic ring 400 outside the positioning column 220, after the positioning column 220 is embedded into the pipe cavity 101, the elastic ring is used for realizing internal fixation, the external fixation is realized by adopting an adhesive mode, and the connection between the cover body 200 and the pipe body 100 is enhanced.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
