Abstract

The invention discloses a connection method of an inhaul cable protecting bush and relates to the technical field of architectural engineering. Protecting elements are adopted, and each protecting element is a half-tube body which is provided with a draw-bore pin and a mortise, wherein the draw-bore pin and the mortise are arranged on two joint parts. Connection is carried out according to the following steps: A, according to the length requirement of an inhaul cable, the protecting bush elements are welded to be a long half tube one by one; and B, the draw-bore pin of one long half tube is inserted into the mortise of the other long half tube to be fastened on the exterior of the inhaul cable. Protruded spiral rib bars are arranged on the outer side faces of the half-tube bodies. The method is simple and easy to practice, prevents the inhaul cable protecting bush and an inhaul cable steel wire from being damaged and improves working efficiency.

Description

The method of attachment of protective sleeve of pulling cable

Technical field

The present invention relates to construction engineering technical field, especially a kind of method of attachment of protective jacket of building guy cable.

Background technology

Along with the fast development that Longspan Bridge is built, cable stayed bridge and suspension bridge obtain applying more and more widely, wire digging line is the critical component being applied to cable stayed bridge and suspension bridge, drag-line inside is steel wire, shaped by band colligation, then pack into high density polyethylene (HDPE) sheath, protective sleeve of pulling cable plays the antisepsis of hawser, present stage protective sleeve of pulling cable installation, first circular pipe type sheath one section a section must be enclosed within before drag-line two ends are fixing on drag-line and then by disconnected and be welded to Len req.This construction method, in the process of reeving, jacket inner wall is likely subject to the damage of drag-line steel wire; And before sheath welding, also need to planish face of weld, need to leave certain space between drag-line and sheath, otherwise easily make drag-line steel wire sustain damage in the process of plane.The method of this connection difficulty of not only planishing large and also easily displacement be difficult to centering, constructing operation is very difficult.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of method of attachment of simple protective sleeve of pulling cable, the method for attachment of this protective sleeve of pulling cable, can solve the problem that the fragile difficulty of protective sleeve of pulling cable is installed.

In order to solve the problem, the technical solution used in the present invention is: the method for attachment of this protective sleeve of pulling cable, adopts a kind of guard component, and this guard component is one section and is respectively equipped with half body of draw pin and tongue-and-groove at two junction surfaces;

Connect according to following steps:

A, needs according to guy cable length, be welded into a long semicanal one by one by described guard component;

B, the tongue-and-groove draw pin of two described long semicanal one sides being inserted the opposing party are fastened on outside drag-line.

In the method for attachment technical scheme of above-mentioned protective sleeve of pulling cable, technical scheme can also be more specifically: be provided with protruding spiral rib at the lateral surface of described half body; When welding described guard component, the spiral rib termination of connected two guard component lateral surfaces is allowed to dock; When fastening two described long semicanals, the termination of the spiral rib of their lateral surfaces is allowed to dock one by one.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:

1, sheath installation can be carried out after drag-line installs, change in the past when reeving jacket inner wall be subject to the damage of drag-line steel wire.

2, the connection of protective sleeve of pulling cable first just packs into drag-line by after half pipeline section welding, avoids the damage of drag-line steel wire.

3, install simple and convenient, improve operating efficiency.

4, the helix of protective sleeve of pulling cable external surface protrusion, can stop the formation of rain line, have the effect of weather proof exciting.

Fig. 2 is the top view of Fig. 1.

Fig. 3 is the structural representation of guard component.

Fig. 4 is the top view of Fig. 3.

Fig. 5 is the I place enlarged drawing of Fig. 2.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the invention will be further described:

Guard component 4 is as shown in Figures 3 to 5 half body being respectively equipped with draw pin 2 and tongue-and-groove 3 at two junction surfaces, is provided with protruding spiral rib 1 at the lateral surface of half body; Multiple guard component 4 are as shown in Figure 1 and Figure 2 connected on drag-line, carry out according to following steps:

A, needs according to guy cable length, mutually dock the termination of guard component 4, be welded into a long semicanal one by one, allows spiral rib 1 termination of connected two guard component 4 lateral surfaces dock when welding; The long semicanal of another root is welded again by preceding method;

B, by two long semicanals parcel drag-lines, form pipe in the tongue-and-groove 3 draw pin 2 of their sides being inserted the opposing party, drag-line is surrounded in this pipe, and the termination of the spiral rib 1 of these two long semicanal lateral surfaces is docked one by one.

The method of attachment of this protective sleeve of pulling cable, simple and convenient, sheath installation can be carried out after drag-line installs, not hinder inwall and the drag-line steel wire of protective sleeve of pulling cable, change circular pipe type sheath in the past and first must overlap the unfavorable situation that loading drag-line could install stay guy two ends.The present invention both may be used for the installation construction of new bridge, can be used for again maintenance and the replacing of old bridge protective sleeve of pulling cable.
