Specifically, the construction device for accurately positioning the combined tower footing steel lattice column comprises
Step 1: firstly, two transverse C-shaped channel steels 1201 of the transverse moving frame 12 are arranged at two ends of a longitudinal square tube 21 of the fixed support frame 2, a fixing bolt 24 sequentially penetrates through the transverse C-shaped channel steels 1201 and a transverse square steel plate 23 to install the fixed support frame 2 on the transverse moving frame 12, and before the fixing bolt 24 is screwed down, two ends of the two transverse C-shaped channel steels 1201 on the transverse moving frame 12 are ensured to be aligned. Similarly, two longitudinal C-channel steels 1101 of the longitudinal movable frame 11 are respectively placed at two ends of the transverse C-channel steel 1201 and locked by the fixing bolts according to the method.
Step 2: four top fixing screws 3 and top fixing angle steels 32 at the tail ends of the four top fixing screws are arranged in four inner corners of the fixed support frame 2, and the handle 31 is rotated to enable the fixing screws 3 to be contracted to the shortest state.
And step 3: the erection positions of the four support rods 1103 of the horizontal positioning adjusting frame 1 are found out through positioning, the steel pipes 9 with the same inner diameter size as that of the support rods 1103 are pre-buried on the ground, and a cover plate is covered for protection.
And 4, step 4: before the steel lattice column 7 and the steel reinforcement cage are hoisted and constructed, the pile hole is qualified through secondary hole cleaning inspection. After the welding of the steel reinforcement cage and the steel lattice column 7 is completed, the steel reinforcement cage and the steel lattice column 7 are lifted by a crane and slowly placed into a pile hole, and after the steel lattice column 7 is placed to the top end of the steel lattice column about half a meter away from the upper edge of the protection cylinder 8, the steel lattice column 7 is inserted into a hole between two batten plates of the steel lattice column 7 through a steel pipe, and the steel lattice column 7 is erected on the protection cylinder 8.
And 5: the horizontal positioning adjusting frame 1 and the fixed supporting frame 2 are integrally lifted by a crane, a # -shaped square hole in the middle of the fixed supporting frame 2 is aligned with the steel lattice column 7 and slowly lowered to the ground, the four support rods 1103 are inserted into a pre-embedded steel pipe 9, and a lifting steel wire rope is unloaded after the horizontal positioning adjusting frame 1 and the fixed supporting frame 2 are firmly fixed. Through 4 top hoisting rings 41 of auxiliary column, lift by crane auxiliary column 4 to 7 tops of steel lattice column, and slowly transfer until apart from 7 top 20 public departments of steel lattice column, keep the couple 43 in the four directions in 4 bottoms of auxiliary column to be in the open mode, the manual work turns to of auxiliary column 4 to become unanimous with 7 directions of steel lattice column transferred, again slowly transfer auxiliary column 4, make four angle steels in 4 bottoms of auxiliary column entangle 7 tops of steel lattice column, treat that 4 bottoms of auxiliary column are aliged with 7 lacing plates of steel lattice column, stop transferring of auxiliary column 4, detain 43 lower covers 7 lacing plates lower edges of steel lattice column with the couple 43 of 4 lower extreme four sides of auxiliary column simultaneously, insert bolt 44 and make couple 43 fixed.
Step 6: and hoisting the auxiliary column 4 again to enable the auxiliary column and the steel lattice column 7 to rise by about 10 centimeters, drawing off the steel pipe clamping the steel lattice column 7, placing two pieces of supporting section steel 5 on two sides of the steel lattice column 7 and the auxiliary column 4, and placing a hydraulic jack 6 below two ends of each supporting section steel 5. Slowly lowering the steel lattice column 7 and the auxiliary column 4 to the lower surface of the hanging lug 42 by 2-3 cm away from the upper surface of the supporting section steel 5, jacking the supporting section steel 5 by using the hydraulic jack 6 and simultaneously lifting the horizontal positioning adjusting frame 1 and the fixed support frame 2, so that the heights of the horizontal positioning adjusting frame 1 and the supporting section steel 5 reach preset elevations. In the jacking process, the positions of the bubbles in the transverse and longitudinal long level bubbles 1102 on the horizontal positioning adjusting frame 1 are continuously observed, and correspondingly, the heights of the four hydraulic jacks 6 are adjusted to enable the bubbles in the long level bubbles 1102 to move to the middle position. And (3) lowering the auxiliary column 4 to hang the hanging lugs 42 on the support section steel 5, rotating the rotating handle 31 on the top fixing screw rod 3 to enable the top fixing angle steel 32 to prop four corners of the auxiliary column 4, and screwing down the rotating handle 31 to enable the auxiliary column 4 to be fixed in a horizontal position. Before the supporting section steel 5 completely bears the total weight of the steel lattice column 7 and the auxiliary column 4, whether the horizontal position of the auxiliary column 4 deviates or not is retested by using the four support rods 1103 on the longitudinal moving frame 11, so that the accurate and error-free axial position of the steel lattice column 7 is ensured. And after confirming that the position of the steel lattice column 7 is correct, the hoisting steel wire rope can be unloaded. The T-shaped stay bars 26 at the bottom ends of the four vertical square tubes 25 below the fixed support frame 2 are opened, so that cross bars of the T-shaped stay bars 26 fall on the upper edge of the auxiliary column 4 batten plate, and the four T-shaped stay bars 26 prop against the lower part of the auxiliary column 4 from four directions to prevent the auxiliary column from displacing.
And 7: when the support rod 1103 is used for repeated measurement, if the deviation exists, the central shaft of the auxiliary column 4 can be located at the set positioning point by adjusting the longitudinal and transverse horizontal positions of the transverse moving frame 12 and the fixed support frame 2.
The specific operation is as follows: and loosening the fixing bolts on the transverse C-shaped channel steel 1201, moving the transverse moving frame 12 to a specified position along the longitudinal moving frame 11, and then retightening the fixing bolts. The operation of the fixed support frame 2 is similar to that of the traverse frame 12, and the detailed description is omitted here.
And 8: and (4) placing a construction operation frame above the horizontal positioning adjustment frame 1, placing concrete pouring guide pipes along the central axis of the auxiliary column 4, and removing the guide pipes after pouring concrete on the pile body. Keeping the horizontal positioning adjusting frame 1, the fixed support frame 2 and the auxiliary column 4 in a standing state, after the pile body concrete is initially set, rotating the handle 31 on the top fixing screw rod 3 in the opposite direction to separate the top fixing angle steel 32 from the auxiliary column 4, adjusting the hydraulic jack 6 to enable the whole device to sink for a section of height after the top fixing screw rod 3 is contracted to the bottom, pulling out the bolt 44, pulling up the hook 43 and the T-shaped support rod 26, lifting the auxiliary column 4 by using a crane, then unscrewing the fixing bolts at two ends of the transverse moving frame 12, pulling out four support rods 1103 on the longitudinal moving frame 11, and detaching two longitudinal C-shaped channel steels 1101. And after the transverse C-shaped channel steel 1201 is removed by the same method, the fixed support frame 2 is lifted by a section of height, the support section steel 5 and the hydraulic jack 6 are removed, and finally the whole fixed support frame 2 is lifted away from the pile hole.
After all the components are used, the components are flushed with water in time and cleaned, and the components are prevented from remaining concrete and solidifying to cause that the next steel lattice column pile foundation cannot be used in construction.
If 7 top elevations of steel lattice column are located above ground, need not to use and assist post 4 to fix a position, can directly use horizontal location alignment jig 1 and fixed bolster 2 to fix a position steel lattice column 7, through the fixed screw 3 direct fixation steel lattice column 7 of top promptly, specific operation is unanimous with the above-mentioned, and this place is no longer repeated.
