Abstract
The utility model relates to a waterproof sealing structure of a cement cable tube. The aim of the utility model is that the provided waterproof sealing structure enables two cement cable tubes to be well sealed, and has the characteristics of being simple in structure and convenient for construction. The technical solution is that the waterproof sealing structure of a cement cable tube is characterized in that the waterproof sealing structure, positioned in a place of connection between a first cement cable tube and a second cement cable tube, comprises a taper hole disposed in an end portion of the first cement cable tube, a taper head disposed on an end portion of the second cement cable tube and matching the taper hole, and at least waterproof assembly arranged between the taper hole and the taper head; the waterproof assembly includes first grooves that are disposed in the inner wall of the taper hole and second grooves that are arranged in the outer wall of the taper head; each first groove and each corresponding second groove face each other and are spliced to form a sealing groove, and each sealing groove is filled with sealing material; and the tube wall of the end portion of the first cement cable tube is provided with sealing material filling holes that are communicated with the sealing grooves.
Description
Technical field
The utility model relates to electric power comb technical field, is specifically related to the waterproof sealing structure of cement cable tube.
Background technology
Cement cable tube is mainly arranged on the location that communication cable and power line intersect; prevent power line occur broken string cause short circuit accident and cause communication cable and steel wire rope charged; thereby protection cable, switch, machine core board; so that complete machine is not burned, and power line magnetic interference is also played to certain buffer action.
Current cement cable duct tube is general, and to adopt high-quality vinylon fibre be basic material, incorporates string, the high-strength height raw materials such as vinylon that rub, and choosing height cement is made as main material.Because cement cable tube is embedded in undergroundly, in order to prevent that underground sewage from entering in cable tube, cable is corroded, conventionally should hermetically-sealed construction be set in the junction of two sections of cement cable tubes.
Utility model content
The technical problems to be solved in the utility model is the deficiency that overcomes above-mentioned background technology, a kind of waterproof sealing structure of cement cable tube is provided, this waterproof sealing structure should be able to be realized two sections of sealings between cement cable tube preferably, and have simple in structure, the feature of easy construction.
The technical solution adopted in the utility model is:
A kind of waterproof sealing structure of cement cable tube, it is characterized in that: described waterproof sealing structure is positioned at the junction of a cement cable tube and No. two cement cable tubes, comprise be opened in a cement cable tube end bellmouth, be arranged on No. two cement cable tube ends the conical heads that coordinate with bellmouth, be arranged at least one water repellent component between bellmouth and conical head; Described water repellent component comprises a groove that is opened in bellmouth inwall and No. two grooves that are opened in conical head outer wall, and a groove and No. two grooves to being spliced to form a seal groove, are perfused with sealing material in opposite directions in seal groove.
On the tube wall of a described cement cable tube end, offer the sealing material fill orifice that is communicated with described seal groove.
Described sealing material fill orifice is the taper hole that outer imperial palace is little, along the radial arrangement of a cement cable tube.
The quantity of described seal groove is two, and the width of one of them seal groove is less than another seal groove.
Described sealing material is pitch.
The beneficial effects of the utility model are: the utility model coordinates by conical head and bellmouth, form longer mating surface, play preliminary sealing function; And the utility model is provided with water repellent component between conical head and bellmouth, perfusion sealing material (pitch) is realized the further sealing between conical head and bellmouth, thereby prevents extraneous sewage intrusion cement cable tube; In addition, sealing material fill orifice is taper hole, the little asphalt reperfusion of outer imperial palace, easy construction.
Accompanying drawing explanation

Fig. 2 is the structural representation of a cement cable in Fig. 1.
Fig. 3 is the structural representation of No. two cement cables in Fig. 1.
Embodiment
Below the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, the waterproof sealing structure of a kind of cement cable tube described in the utility model, is positioned at the junction of a cement cable tube 1 and No. two cement cable tubes 2, the coaxially arranged and docking mutually of cement cable tube and No. two cement cable tubes.Described waterproof sealing structure comprise be opened in a cement cable tube end bellmouth 1-1, be arranged on No. two cement cable tube ends the conical head 2-1 coordinating with bellmouth, be arranged at least one water repellent component between bellmouth and conical head, described bellmouth is outer imperial palace minor structure, from the end of a cement cable tube, inwardly reduces gradually aperture.
As shown in Figure 2 and Figure 3, described water repellent component comprises a groove 3-1 who is opened in bellmouth inwall and No. two groove 3-2 that are opened in conical head outer wall, groove and No. two grooves are all in the form of a ring and axis and bellmouth and conical head coaxial line, groove and No. two grooves are in opposite directions and to being spliced to form a seal groove 3, in seal groove, be perfused with sealing material (recommend adoption pitch also can prevent after bitumen embedding that No. one, No. two cement cables from large moving axially occurring).On the tube wall of a described cement cable tube end, offer the sealing material fill orifice 4 that is communicated with described seal groove.Described sealing material fill orifice is that (aperture near outer wall is large for the taper hole that outer imperial palace is little, inwardly reduce gradually), along the radial arrangement of a cement cable tube, usually, in work progress, sealing material fill orifice is arranged the perfusion operation that is beneficial to pitch upward.
The quantity of described seal groove determines as required, thereby and the width of seal groove from the inner side, lateral of bellmouth, reduce gradually to save pitch, reduce costs and the engineering time.Due to the axial length restriction of conical head and bellmouth, recommending seal groove quantity is two, and wherein the width of outside seal groove is less than the width of inner seal groove.
