in the figure, a sliding rod 1, a protection plug 2, a jacking 2.1, an elastic part 2.2, a rubber plug 2.3, an annular retainer ring 2.4, a taking-out hole 2.5, a sliding sleeve 3, a jacking screw 4 and scale marks 5.

Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1 and 2, an integrated form protection stopper for underground cavern bottom plate tendon hole slip casting before, including a plurality of protection stoppers 2 of locating on the slide bar 1, protection stopper 2 includes top support 2.1, top support 2.1 bottom is connected with rubber buffer 2.3 through elastic component 2.2, and sliding sleeve 3 and 1 surface sliding fit of slide bar are passed through at top support 2.1 top, rubber buffer 2.3 and tendon hole cooperation.

Preferably, the surface of the sliding sleeve 3 is further provided with a screw hole for penetrating the tightening screw 4. After the design, when the sliding sleeve 3 slides to a designated position on the sliding rod 1, the jacking screw 4 can be screwed down, so that the sliding sleeve 3 is jacked on the sliding rod 1, and a good limiting effect is achieved.

Preferably, the elastic element 2.2 is of an elastic rod or spring structure. One elastic component 2.2 can play the effect of connecting top support 2.1 and rubber buffer 2.3, and the two is taking place to twist or when crooked when pushing up between 2.1 and the rubber buffer 2.3, and elastic component 2.2 can play good cushioning effect, avoids being broken directly.

Preferably, the bottom surface of the jacking 2.1 is also provided with an annular retainer ring 2.4, and the outer diameter of the annular retainer ring 2.4 is larger than the aperture of the anchor rib hole. Annular retaining ring 2.4 can seal the horizontal position in the regional top of anchor bar hole, and the mode rivers are transversely scurried into in the anchor bar hole.

Preferably, the slide bar 1 is a telescopic bar structure. In this embodiment, the telescopic form of sleeve and loop bar can be chooseed for use to slide bar 1, can adjust the length of whole slide bar 1 like this, both conveniently accomodate, also conveniently adjust length.

Preferably, the surface of the sliding rod 1 is provided with scale marks 5. The distance between the sliding sleeves 3 can be obtained quantitatively through the scale marks 5, so that the distance between the protection plugs 2 can be accurately obtained, and the distance between the protection plugs 2 can be accurately adjusted according to the distance between the anchor bar holes.

Preferably, the edge of the top support 2.1 is also provided with a taking-out hole 2.5. When whole rubber buffer 2.3 was difficult for following the anchor muscle hole and is pulled out, can conveniently pull out protection stopper 2 through the large-size word play or the perk of stereoplasm slender pole push up 2.1 take out hole 2.5.

The working principle of the embodiment is as follows:

after the anchor bar holes of the bottom plate are formed, a plurality of anchor bar holes are arranged in a matrix; at the moment, firstly, the length of a sliding rod 1 is adjusted, then a sliding sleeve 3 is moved, the sliding sleeve 3 slides to a specified position on the sliding rod 1 according to the space between anchor bar holes, then a tightening screw 4 is screwed, so that the sliding sleeve 3 is tightly pressed on the sliding rod 1, then a protection plug 2 on the whole sliding rod 1 is aligned with the anchor bar holes and then pressed downwards, and a plurality of protection plugs 2 are plugged into the anchor bar holes at one time;

when the protective plugs 2 are to be taken out, one end of the sliding rod 1 can be directly lifted, so that the protective plugs 2 can be pulled out simultaneously through the lever principle, when certain rubber plugs 2.3 are too tight and difficult to pull, only a large-size straight rod or a hard slender rod is needed to be used, one end of the large-size straight rod or the hard slender rod is inserted into a reserved taking-out hole 2.5 of the jacking support 2.1, the other end of the large-size straight rod or the hard slender rod is held by a hand to be pressed downwards forcibly, and the jacking support 2.1 is also tilted upwards for a certain height through the lever principle, so that the rubber plugs 2.3 can be pulled out easily.

The above embodiments are merely preferred technical solutions of the present invention, and should not be considered as limitations of the present invention, and the features in the embodiments and the examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention shall be defined by the claims and the technical solutions described in the claims, including the technical features of the equivalent alternatives as the protection scope. Namely, equivalent alterations and modifications within the scope of the invention are also within the scope of the invention.
