Abstract
The invention discloses a method for arranging a parallel steel wire stay cable, which comprises the following steps of: 1) arranging a tower end anchor head at the end of the stay cable; 2) arranging a planetary jack and a tower end anchor head nut of the stay cable on an anchor backing plate which is arranged at the pipe orifice of a cable guide pipe on the inner side of the wall of a cable bent tower; 3) lengthening a pulling steel stranded wire meeting the requirement at the tower end anchor head of the stay cable; 4) hoisting the tower end anchor head of the stay cable to a position nearby the pipe orifice of the cable guide pipe on the outer side of the wall of the cable bent tower by using a hoisting machine on the top of the cable bent tower; 5) pulling the end of the pulling steel stranded wire to pass through the cable guide pipe and anchoring on the planetary jack; and 6) pulling the pulling steel stranded wire by using the planetary jack, pulling part of the tower end anchor head of the stay cable to exceed the anchor backing plate and screwing the tower end anchor head nut of the stay cable at the tower end anchor head so as to cap the tower head anchor head. The method can effectively avoid the sling accidents of the stay cable, makes the whole construction process convenient and quick and contributes to the linear control of bridges.
Description
Technical field
The invention belongs to method for bridge construction, be specifically related to a kind of mounting method of parallel steel wire suspension cable.
Background technology
At present, in the installation of parallel steel wire suspension cable, mainly contain the traction mounting means of the beam-ends soft or hard combination of the traction mounting means of tower end soft or hard combination of soft traction stiffened traction and the traction of soft traction stiffened.
First kind of mounting means adopts the continous way jack to add the traction that steel strand add the rigidity tension rod of different length to carry out stretch-draw construction method again: this job practices utilizes the less jack of tonnage by steel strand the termination of rigidity tension rod to be pulled out anchor plate earlier, utilize clasp nut to be attached the names of pre-determined candidates in the tension rod termination, then that tonnage is less jack is converted to the inclined guy cable stretching jack, utilize inclined guy cable stretching jack tension tension rod, the suspension cable anchor head is drawn to the tower end position of attaching the names of pre-determined candidates.This job practices takies very greatly owing to multiple reason is easy to cause tension rod fracture that suspension cable falling accident and construction operation space take place in work progress, uses often restricted.
Second method need be utilized at the semi girder front end large-scale removable suspension bracket carries out suspension cable as operation platform installation is set.The general tonnage of this suspension bracket is bigger, and is big to the linear influence of bridge, and construction monitoring is difficulty comparatively, and efficiency of construction is low, the duration is also longer, and personnel are in that to be exposed to the dangerous operation face time long.
Summary of the invention
The purpose of this invention is to provide a kind of safer, easy construction, the mounting method of parallel steel wire suspension cable efficiently.
The technical scheme that realizes the object of the invention is: the mounting method of parallel steel wire suspension cable may further comprise the steps:
1, with suspension cable behind bridge floor exhibition rope, in the end of suspension cable tower end anchor head is installed;
2, the tower end anchor head nut of planet jack and suspension cable is set on the anchor plate that is located at the Sarasota wall medial strand conduit mouth of pipe;
3, satisfactory traction steel strand are longer on the tower end anchor head of suspension cable;
4, the hoist engine that utilizes the Sarasota top is promoted to the tower end anchor head of suspension cable near the Sarasota wall outside mouth of pipe of cable guide pipe;
5, will draw the traction of steel strand termination by the cableway pipe, and be anchored on the planet jack;
6, utilize planet jack traction traction steel strand, the tower end anchor head of suspension cable is partly drawn exceed anchor plate, the tower end anchor head nut screwing clamping of suspension cable is realized that on the tower end anchor head of suspension cable tower end anchor head attaches the names of pre-determined candidates.
In the described step 3, the length of described satisfactory traction steel strand and radical are finished under the situation of installation at its tower end anchor head according to precalculated suspension cable, and the tower end anchor head required tractive force of attaching the names of pre-determined candidates is determined.
In the described step 6, the length that the tower end anchor head of described suspension cable exceeds anchor plate is as the criterion with the thickness of the tower end anchor head nut of suspension cable.
The characteristics of the inventive method are, utilize steel strand that the tower end anchor head of suspension cable is pulled out anchor plate to the position of attaching the names of pre-determined candidates fully, do not adopt the rigidity tension rod to draw in whole distraction procedure.It not only can make the generation of effectively having stopped to take place because of the tension rod fracture bob rope accident, be not subjected to the restriction in construction operation space substantially, and work progress is less to the linear influence of bridge, personnel's job safety.Its whole construction course is convenient, fast, and has shortened the duration greatly.This method is applicable to the suspension cable installation of all cable stayed bridges.
