As shown in fig. 1, the deck 23 and pier structure 22 of the steel tower 2 have been substantially completed prior to erection of the guideway-type steel tower installation system 1, and additionally the fixed engineering interface adjacent to said steel tower 2 has been rammed for subsequent use as a column foundation 3. The cable tower 2 will be divided into several tower segments 21 for butt-mounting. The rail type installation system 1 of the steel cable tower comprises:
The guide rail type jacking bracket 11 comprises an inclined vertical guide rail 111, a guide rail support 112 arranged on the inclined side of the vertical guide rail 111, a lifting power mechanism 113 arranged at the top end of the vertical guide rail 111, and a traction wire 114 which is led out from the lifting power mechanism 113 and extends towards the bottom end of the vertical guide rail 111;

Further, the inclination angle of the vertical guide 111 is consistent with the design inclination angle of the rope tower 2 for stabilizing the design linearity of the rope tower 2, and in particular, the vertical guide 111 is disposed at a side of the rope tower 2 inclined to form an acute angle with a horizontal plane (or the ground) such that the vertical guide 111 supports the rope tower 2 from the rear surface of the rope tower 2. The vertical guide rail 111 comprises a set of vertical slide rails 111 'for supporting the tower body of the steel rope tower 2, preferably, each of the vertical slide rails 111' constituting the vertical guide rail 111 is arranged in parallel along the surface profile of the tower body of the steel rope tower 2. If the surface profile of the tower body of the steel cable tower 2 is curved, the vertical guide rail 111 is provided with at least two vertical guide rails 111' which are not on the same plane and are used for supporting the tower body of the steel cable tower 2 together. In this embodiment, referring to fig. 2, the vertical guide rail 111 is disposed on a longitudinal plane provided by the guide rail support 112, the width of the longitudinal plane is slightly larger than the maximum lateral width of the tower 2, the vertical guide rail 111 includes at least two vertical sliding rails 111 'extending from the top to the bottom of the longitudinal plane and parallel along the longitudinal axis, each vertical sliding rail 111' includes a rail pad 111a, a sliding rail 111b and a sliding block 111c that are sequentially stacked, where the sliding rail 111b and the sliding block 111c can slide relatively, and the top surface of the sliding block 111c directly abuts against the tower body surface of the tower 2; further, since the cross-sectional profile of the tower body of the illustrated steel cable tower 2 is curved, in order to ensure the supporting stability of the vertical guide rail 111 on the steel cable tower 2, two points of the surface of the tower body of the steel cable tower 2, which are not on the same plane, are selected as supporting points of the sliding blocks 111c, and the supporting points are symmetrical about the axis of the steel cable tower 2, so that the supporting points are dispersed as much as possible, as shown in the figure, the two vertical sliding rails 111' are arranged at the position with the largest curvature in the curved profile line, and the non-coplanarity of the sliding blocks 111c is realized by arranging wedge blocks 111d with different inclination angles under each vertical sliding rail (specifically under the rail pad 111 a).
With continued reference to fig. 1, the rail support 112 includes a group of first upright posts 1121 fixedly mounted on the vertical rail 111, and a plurality of second upright posts 1122 intersecting the first upright posts 1121 at an acute angle for reversely and obliquely supporting the first upright posts 1121, that is, the first upright posts 1121, the second upright posts 1122 and the horizontal plane form a bracket structure of an acute triangle, and the same first upright post 1121 is supported by a plurality of second upright posts 1122 parallel to each other. Preferably, the bottom end of the first upright 1121 is fixed on the bearing platform 23 of the steel cable tower 2; the bottom ends of the second columns 1122 are fixed to the column foundation 3 adjacent to the rope tower table 23, so that the bottom ends of the first columns 1121 and the second columns 1122 are not on the same horizontal plane in most cases. In order to enhance the structural stability of the rail support 112, parallel joints 1123 are disposed between the first upright posts 1121, and a frame structure formed by the first upright posts 1121 and the parallel joints 1123 is mainly used as an installation plane of the vertical rail 111; a reinforcing rod 1124 is disposed between the adjacent second columns 1122, and the reinforcing rod may further include a parallel connection (not numbered) perpendicularly intersecting with the second columns 1122, and diagonal braces (not numbered) intersecting between the adjacent parallel connection, and other forms of members that may be used as reinforcing rods may be used in the present application, and should not be taken as limiting the present application. Further, the angle between the first and second columns 1121, 1122 should be determined according to the load carried by the rail support 112, the condition of the column foundation 3, and in principle not exceeding 90 °.
The lifting power mechanism 113 is fixedly arranged at the top end of the vertical guide rail 111, and is used for lifting the load from bottom to top through the traction wire 114, in particular from bottom to top along an angle defined by the vertical guide rail 111. The lifting power mechanism 113 should be selected as a suitable power mechanism, such as a hoist or a crane, according to the size of the load. The traction wire 114 includes a lifting section 1141 extending forward from the lifting power mechanism 113 to a point of application of a pulling force, and a reaction section 1142 extending in a reverse direction from the lifting power mechanism 113, the reaction section 1142 requiring a fixed engineering interface to provide a reaction force to the lifting force. The fixed engineering interface is typically the upper surface of the platform 23, the column foundation 3 or other fixed engineering interface adjacent to the mounting system 1, which should be reasonably chosen by the skilled person in view of the counter force requirements.
The transfer platform 12 is used to run the tower sections 21 of the rope towers 2 over the pier structure 22 for docking installation. Specifically, the sliding platform 121 of the transferring platform 12 extends from the front surface of the vertical rail 111 to the top of the pier structure 22, and the front surface of the vertical rail 111 is understood to be a direction out of the range of the rail support 112, and according to the actual situation of the construction site, the sliding platform 121 should not be limited to a platform that is linearly connected to the tower segment 21 to transfer from the origin to the upper side of the pier structure 22. Further, the sliding platform 121 may be matched with the construction trestle 4 of the bridge engineering, that is, extend from the front surface of the vertical guide rail 111 to the construction trestle 4 through the top of the pier structure 22, so that the tower segment 21 unloaded at the construction trestle 4 is transported to a designated position. Further, since the bottom end of the rail support 112 is fixed to the bearing platform 23 or the column foundation 3, the tower segment 21 is mounted on the pier structure 22, and thus the sliding platform 121 is disposed at a position shifted down from the middle of the vertical rail 111. The sliding trolley 122 is used for directly conveying the tower segment 21, so as to ensure the safety and the efficiency of conveying, and the transferring platform 12 further comprises a horizontal sliding rail (not shown) for limiting the translation track of the sliding trolley 122 on the sliding platform 121, and the laying of the horizontal sliding rail can be realized by adopting a known method. If the tower segment 21 is laid in a horizontal position when the tower segment 21 is unloaded at the construction trestle 4 or other position far away from the construction site of the steel cable tower 2, before the tower segment 21 is transferred onto the sliding trolley 122 (or before the sliding trolley approaches to the docking installation position), the tower segment 21 needs to be adjusted from the horizontal position to the vertical position, and then a lifting tool 124 (e.g. an automobile crane or a crawler crane) is needed to assist in adjusting the posture of the tower segment 21.
The guide rail type installation system 1 of the steel cable tower is utilized to assemble the tower segments 21 of the steel cable tower 2, and the guide rail type installation method of the steel cable tower comprises the following steps:
s1, erecting a guide rail type jacking bracket on one side of a steel cable tower pier column, and erecting a transfer platform on the pier column.
As shown in fig. 1, in the construction position of the tower 2, the rail type jacking bracket 11 is erected on the inclined side of the tower 2 after the bearing platform 23 and the pier structure 22 are substantially completed, and the rail type jacking bracket 11 is constructed as described above, that is, includes an inclined vertical rail 111, a rail support 112 provided on the inclined side of the vertical rail 111, a lifting power mechanism 113 provided on the top end of the vertical rail 111, and a traction wire 114 led out from the lifting power mechanism 113 and extending toward the bottom end of the vertical rail 111.
The transfer platform 12 comprises a sliding platform 121 extending outwards from the guide rail type jacking bracket 11, and a sliding trolley 122 translating on the sliding platform 121. The transfer platform 12 is used to connect a site of unloading the tower segment 21 to a site of docking installation of the tower segment 21.
S2, positioning a first section at the top end of the segmented steel cable tower at the top of the pier column through a transfer platform;
From the top of the cable tower as a counting start position, the tower segment 21 of the first segment is transported from its unloading site (e.g. construction trestle 4) to above the pier structure 22 by means of a skid trolley 122, the axial position of the tower segment 21 is adjusted by means of various adjusting tools (e.g. three-way jacks and wedges) until it coincides substantially with the setting-out line, and the side wall surfaces of the tower segment 21 are brought into close contact with said vertical rails 111, whereby the positioning of the first segment is achieved.
Further, before the tower segment 21 is transferred above the pier structure 22, if the tower segment 21 is in the horizontal posture at the construction trestle 4 or other unloading position, the conversion of the vertical posture on the sliding trolley 122 needs to be achieved with the aid of the hoisting tool 124.
S3, after the first section is lifted by the guide rail type jacking bracket 11, a second section below the first section is positioned;
As shown in fig. 1, after the tower segment 21 of the first segment is properly positioned, the tower segment 21 of the first segment is lifted a distance along the vertical rails 111 using the lift power mechanism 113 and the pull lines 114 of the rail jacking bracket 11 to facilitate the positioning of the tower segment 21 of the second segment above the pier stud structure 22.
Specifically, the lifting section 1141 of the traction wire 114 is led out from the lifting power mechanism 113, the end of the lifting section 1141 is connected with a preset hanging point on the outer side wall of the tower segment 21 of the first segment, the lifting hanging point is arranged on the outer side wall of the tower segment 21, so that the hanging point can be conveniently moved downwards from the previous segment to the next segment, and the operation space is larger when the constructor performs the hanging point conversion, so that the operation difficulty is reduced; further, the lifting points are preferably disposed on two adjacent side walls of the tower segment 21 opposite to the side walls closely attached to the vertical guide rail 111, so that the pulling force required for lifting can be reduced, and the load requirement of the lifting power mechanism 113 can be reduced.
The second section tower section is positioned on top of the pier in a similar manner as the first section tower section 21: the tower segment of the second segment is transported from its discharge location over pier stud structure 22 by skid cart 122, and its extreme axial position is adjusted by various adjustment tools so as to substantially coincide with the loft line and to bring its side wall surfaces into close proximity with the vertical rails 111.
S4, after butt welding the first section and the second section to form a butted section, lifting the butted section;
Referring to fig. 3, the lifting power mechanism 113 is reversely activated such that the tower segment 21 of the first segment, which has been lifted, is lowered onto the top surface of the tower segment of the second segment, and then the tower segment 21 of the first segment and the tower segment of the second segment are subjected to butt welding such that the two tower segments, which are integrated after butt welding, form a butted segment 211. Next, the end of the lifting section 11141 of the transfer wire 114 is fixed at the lifting point of the outer side wall of the tower section of the second section, which is preferably disposed directly below the lifting point of the tower section 21 of the first section, so as to facilitate the lifting point conversion operation by the constructor. Further, the lift power mechanism 113 is again used to pull the pull lines 114 to lift the docked section 211 a distance along the vertical rail 111 so that the next tower section (the tower section of the third section) is in place above the pier structure.
S5, circularly installing the rest sections in the installation procedure of the second section;
The next tower segment is left in place over the pier stud structure 22 by the lifting process, and the remaining tower segments are cyclically installed with the second segment installation process to progressively extend the cable tower from top to bottom. The second segment installation procedure refers to the above-mentioned step S3 and step S4. Each time a lifting process is performed using the lifting power mechanism 113, the traction wire 114 is connected to the tower segment at the lowermost end of the docked segment 211.
S6, carrying out falling frame connection on the butted sections and pier columns so as to finish the installation of the steel cable tower.
After the last tower segment is butt welded to the docked segment 211, the entire docked segment 211 may be subjected to a racking process. Falling frames generally refer to the transfer of load from a temporary support structure to a permanent support structure. The landing connection performed in this embodiment means that the docked section 211 supported by the track type lifting frame 11 is transferred to the pier structure 22, and the docked section 211 is supported by the pier structure 22 to complete the installation of the cable tower 2. The adjustment of the planar position and height of the docked sections 211 is performed prior to the landing connection of the docked sections 211 with the pier stud structure 22 to provide the final linear adjustment of the pylon 2.
After the installation of the steel cable tower 2 is completed, the guide rail type jacking bracket 11 can be temporarily reserved as an auxiliary structure for supporting the steel cable tower 2 until the installation of the stay cable of the bridge is needed. When the installation and debugging of the stay cable are completed, the inclined steel cable tower 2 is in a force balance state, and can stably maintain an inclined state.
In summary, the guide rail type jacking bracket is used for installing the inclined steel cable tower, so that the butt joint precision of the steel cable tower is controlled, the butt joint adjustability of the steel cable tower is improved, the operation difficulty and complexity of the construction process are reduced, and the construction safety is also improved.
The above embodiments are preferred embodiments of the present application, but are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and principles of the present application should be made therein and are intended to be equivalent substitutions within the scope of the present application.
