Abstract
The invention discloses a mounting bolt special for a leaking cable. The bolt comprises a bolt body and a nylon casing, wherein the cross section of the bolt body takes the shape of T; a through hole is formed in the center of the T-shaped bolt body; the bottom side of the end part of the T-shaped bolt body is a toothed side; a circular fixed boss is arranged at one end part of the nylon casing; an axial groove is formed in the end part of the other end of the nylon casing; a barb is arranged on the outer wall, close to the circular fixed boss, of the nylon casing; the nylon casing is embedded into the through hole. According to the scheme of the invention, the bolt is simple and practical in structure and convenient to machine. When the bolt is mounted and used, no holes are needed to be formed in a shielding subway tube piece, the mounting speed is fast, and the stable effect is good.
Description
Technical field
The present invention relates to the special construction bolt of a kind of leaky cable, this construction bolt is used in particular for the installation of the leaky cable in subway engineering shield tunnel.
Background technique
At present, need to arrange numerous cables in subway tunnel, cable also all concentrates on respectively in multiple wire casings by function difference, and wire casing is to be generally fixed on shield structure subway segment by cable bearer.Common, the installation of leaky cable is all to punch on shield structure subway segment, is then connected with leaky cable support through EXPANSION ANCHOR BOLTS.This mounting structure is because needs punch on shield structure subway segment, and special-purpose machinery is beaten the every linear meter(lin.m.) of installation eyelet and needed more than 30, wherein have 2/5ths all can beat on reinforcing mesh, just needs again beat lost labor and man-hour again; And the eyelet of scrapping needs to fill, destroyed tunnel duct piece easily seeps water.Quality to shield structure subway segment impacts.And because the eyelet distance of beating on shield structure subway segment is too near, make the bearing capacity of shield structure subway segment inadequate, cause potential safety hazard.
Therefore, how addressing the above problem, is the content that those skilled in the art will study.
Summary of the invention
The invention provides a kind of without punching, the special construction bolt of installation rate leaky cable fast, that stablizing effect is good.
For achieving the above object, the technical solution used in the present invention is: the special construction bolt of a kind of leaky cable, comprises bolt body, nylon sleeve; The cross section of described bolt body is T-shape, and the center of T-shape bolt body is provided with through hole, and the bottom surface of described T-shape bolt body end is toothed surface; The end, one end of described nylon sleeve is provided with circular fixing lug boss; The end of its other end is provided with axial notch; Described nylon sleeve is provided with barb near the outer wall of circular fixing lug boss; Described nylon sleeve is embedded in described through hole.
Related content in technique scheme is explained as follows:
1,, in such scheme, the outside dimension of described circular fixing lug boss is greater than the internal diameter size of described through hole.
2,, in such scheme, the internal diameter of described through hole and the external diameter of described nylon sleeve match.
3, in such scheme, the end of described T-shape bolt body is rectangle, and the base of this rectangle is toothed surface.
4, in such scheme, described through hole is the combination of end trapezoidal hole and rear minister's straight hole, and the top of trapezoidal hole is connected with long straight hole.
5,, in such scheme, the end that described nylon sleeve is provided with axial notch is taper type.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1, the present invention is simple in structure, practical, and easy to process.While installing and using, without on shield structure subway segment punching and installation rate is fast, stablizing effect is good.
2, due to the present invention in use, need on shield structure subway segment, not punch, install, saved man-hour, greatly reduce workman's labor intensity, and avoided because of the potential safety hazard of bringing that shield structure subway segment is punched.
