The hoist installation beam 7 is made of square steel pipe, and is clamped to the top longitudinal parallel connection 4c through the U-shaped locks at both ends. Other detachable installation structures can also be used, such as additional flanges for detachable installation.

As shown in Figure 1 and Figure 3, the anti-sliding pile main reinforcement hanger C is based on the anti-sliding pile orifice lifting frame A, the front top horizontal parallel 5 is removed, and four uprights 4a are added. The hoist 8 and the fixed pulley 9 are refitted. Additional lateral parallel couplings 10 are also provided between the two uprights 4a on the rear side. Preferably, in addition to the front side, additional lateral parallelings 10 are also provided between the left and right uprights 4a.

The middle of the two additional longitudinal parallel links 11 is provided with an additional top horizontal parallel link 12 for installing the fixed pulley 9, and the wire rope of the hoist 8 bypasses the fixed pulley 9 and extends to the front side of the orifice bracket 4 for pulling down the main reinforcement. The upper ends, preferably, are connected at the rear end of the two additional longitudinal parallel links 11 by another additional top transverse parallel link 12 .

1-3, the column 4a, the top longitudinal parallel connection 4c, the lateral parallel connection 4b, the top horizontal parallel connection 5, the additional lateral parallel connection 10, the additional longitudinal parallel connection 11, and the additional top horizontal parallel connection 12 respectively adopt square It is made of tube and has a larger cross-sectional dimension than the diagonal brace 13 . The ends are respectively welded with flanges, and the connection parts are detachably installed through the flanges combined with bolts, but not limited to this structure. In the process of part erection, the parts can be welded according to the actual situation without affecting the overall stability of the frame body, so that the frame body has better mechanical performance.

First of all, the lifting frame of the anti-sliding pile orifice is erected, and the reinforcement cage binding of the anti-sliding pile is generally divided into two stages: stirrup binding and main reinforcement binding. The main reinforcement is bound into a steel cage. In the stirrup binding stage, the anti-sliding pile orifice lifting frame is modified, and a chain hoist is used to control the reinforcement cage; for the main reinforcement binding stage, the main reinforcement is hoisted by a crane, and then modified based on the anti-sliding pile stirrup binding frame. A hoist is added to bind the main tendons. The construction steps are as follows: after the lock strength reaches the design requirements, the anti-sliding pile orifice lifting frame is erected, and the equipment is assembled for debugging. In the stirrup binding stage, two hoist installation beams are added to the top longitudinal parallel connection, and four chain hoists are suspended at the four corners through the two hoist installation beams to control the lowering of the stirrup cage. The reinforcement cage is positioned, and the stirrup cage is bound in sections and lowered one by one. In the process, the length of the main reinforcement is increased and the protective layer is controlled by guard piles in each section, and the operation is repeated to the bottom of the pile. For the lashing stage of the main tendons, lashing is carried out in two situations. First of all, according to the situation of good site and sufficient budget, cranes are used to hoist the main bars, and the main bars are lengthened and tied together in the site. The cranes are hoisted to the hole and lowered, and the personnel in the hole are tied and fixed. In view of the poor site and insufficient budget, the anti-sliding pile stirrup binding frame was refitted and heightened, and a hoist was added. After the heightening, a fixed pulley was suspended on the top of the frame for the drive of the hoist to hoist the steel bar. The hoist is lifted into the hole for binding.

During the specific construction, the first stage: after the anti-sliding pile locking construction is completed, the hole is covered with bamboo plywood, and four columns are erected. Thick steel plates are used to connect the columns and the concrete foundation through expansion bolts. The steel pipe is used as a lateral parallel connection, and the flanges are welded at each connection and the bolts are locked with a hand electric drill; after the vertical parallel connection at the top is erected, the horizontal parallel connection at the top can be erected; an excavator can be used to lift the hoisting rail and electric hoist and connect the Carry out lap assembly; hang the seat belt on the flat joint, support the herringbone ladder on the ground and assemble the diagonal support at the end of the lifting rail, then debug the circuit and connect the power supply, remove all the bamboo plywood and install the blower and air compressor. Wait for the equipment to be erected, and then install the protective shed after completion.

The second stage: the top of the lock is covered with bamboo plywood to seal the hole, move the electric hoist to the middle and rear of the hoisting rail and cut off the power supply, remove the surrounding protective shed, and hang the back cage on the top of the frame after processing. Two hoist installation beams are manually added at the top of the vertical parallel connection 20cm away from the horizontal parallel connection at the top of the two outer sides and fixed with U-shaped locks. After the belt is hung on the flat joint, the back cage is removed and the stirrups are bound. The four main bars are fixed to the four corners of the stirrups and fixed by spot welding. Four round pipes are used to support the four corners of the stirrup cage. The stirrups are bound upwards according to the design spacing with tie wire to the operating height of the personnel. The stirrups at the operating height of the personnel are fixed by spot welding again. The lower ends of the four chain hoists are bolted to the top stirrups, and the four round pipes are removed to fix the stirrups. Lower the stirrup cage to the height of the top stirrup, and then use the round tube to support the stirrup cage on the lock, and repeat the cycle to bind the stirrups and lower them to the bottom of the hole.

The third stage: In view of the poor construction conditions, after the stirrups are bound, use bamboo plywood to build the top of the stirrups to seal the holes, hang the back cage on the top of the frame, and use bamboo plywood to fill the top flat joint gap. , Use four square tube columns to lengthen the column. After connecting the column, use protective mesh to surround the left, right and rear sides and install additional top flat joints. After hanging the back cage on the flat joint, use the springboard for full paving. , the safety belt is attached to the upper parallel connection, the safety net is removed and then moved to the upper parallel roof. The personnel go to the top of the springboard through the back cage to assemble the last part of the parallel connection, and hang the fall arrester and the fixed pulley on the top of the frame. Connect the anti-fall device to install the electric winch, remove the bamboo plywood after completion, use the back cage to go down to the ground, pull the anti-drop device to the bottom to hang, start the main reinforcement lashing, and transfer each main reinforcement to the lock for storage. The hoist is pulled up and hoisted into the hole for binding.
