It should be noted that for the sake of clarity in showing the structures of the various components of the embodiments of the present invention, the drawings are not drawn to the same scale. Like reference numerals are used to denote like parts.

A structure schematic diagram for utility tunnel's novel railing, as shown in figure 1. The novel railing for the utility tunnel comprises a railing body 10 and a movable base 20. The rail main body 10 comprises upright posts 11, cross bars 12 and a bottom plate 13, as shown in fig. 2, the upright posts 11 and the cross bars 12 are arranged in a staggered manner, and the bottom plate 13 is welded at the bottom of the upright posts 11; the movable base 20 includes a base 21 and a clamping portion 22, as shown in fig. 3, the clamping portion 22 is disposed on the top surface of the base 21, a clamping groove 22a is disposed on one side of the clamping portion 22, a fixing hole 22b with a single end open is disposed on the top surface of the clamping portion 22, and the bottom plate 13 of the handrail main body 10 is detachably disposed in the clamping groove 22a of the movable base 20, as shown in fig. 5.

As an embodiment of the present invention, the number of the movable bases 20 is plural, and as shown in fig. 1, the openings of the locking grooves 22a are oriented in the same direction and are arranged at intervals along the linear direction. Further, the number of the bottom plates 13 of the railing body 10 matches with the number of the movable bases 20.

The utility model discloses in, fixed orifices 22b is the rectangular hole, as shown in fig. 4, and its opening width is followed joint portion 22's length direction diminishes gradually to the bottom plate 13 of railing main part 10 smooth and easy card plug-in joint portion 22. Preferably, the opening width of the fixing hole 22b is larger than the diameter of the upright 11.

As an embodiment of the present invention, the locking groove 22a is a wedge-shaped groove, as shown in fig. 6, the longitudinal height of the outer end is greater than the longitudinal height of the inner end. Specifically, the longitudinal height of the clamping groove 22a is matched with the height of the bottom plate 13 to ensure smooth clamping and fixing of the bottom plate 13

Fig. 4 is a top view of the movable base of the present invention, wherein the movable base 20 is configured with mounting holes 23, and the mounting holes 23 are distributed at four corners of the base 21.

Further, the mounting hole 23 is a long hole, and the long hole is disposed along the length and/or width direction of the base 21.

The clamping portion 22 and the base 21 are integrally formed, and the clamping groove 22a is arranged along the length direction of the clamping portion 22 in a penetrating mode, so that the position of the movable base 20 can be accurately adjusted.

Novel the whole weight of railing is light and handy, and single can light and handy removal railing, activity base 20 is fixed in piping lane structure top surface by expansion bolts, need not to reserve in advance pre-buried, and the railing main part is installed on the base, realizes the purpose of activity railing. And simultaneously, the utility model provides a hoist and mount mouth face the problem that limit entrance to a cave's protection railing activity was installed and is torn open, reliably fixed through expansion bolts and structure, it is pre-buried to need not to reserve among the preceding stage concrete placement process, need not later stage water and bores the opening and destroy the structural reinforcement, convenient and fast, the edge hole protection safety problem that faces when having guaranteed the pipeline hoist and mount transportation, guarantee operation personnel safety.

After the construction of piping lane structure is accomplished, consider that there is personnel to come in and go out in the intermediate layer, the hoist and mount mouth faces the limit and has the risk that personnel fall, can install movable railing according to the construction drawing earlier, when treating the installation of the interior pipe of corridor, demolish railing main part 10 before the pipeline hoist and mount transportation, only leave movable base 20, because of movable base 20 is only higher than ground not much, do not influence pipeline hoist and mount completely, the pipeline all hoists to the corridor in insert movable base with railing main part 10 once more.

Meanwhile, in the pipe gallery operation stage, if the pipeline equipment in the pipe gallery needs to be changed, hoist and mount the transportation from this hoist and mount mouth, hoist after the railing has hindered that the pipeline transportation also can be demolishd the railing temporarily to realize the purpose of activity railing.

The present invention is not limited to the above embodiments, and any person can obtain other products in various forms without departing from the scope of the present invention, but any change in shape or structure is included in the technical solution that is the same as or similar to the present invention.
