Problems solved by technology

[0003] The purpose of the present invention is to provide a method for manually lowering the overweight reinforcement cage of the excavated pile, which solves the situation that the lifting equipment at the construction site cannot put down the reinforcement cage, and utilizes the square frame and the reinforcement cage placed on the reinforced concrete wall of the pile foundation The four U-shaped card slots at the lower part fix the nylon rope, and the reinforcement cage is bound and lowered manually. This method avoids various problems when using lifting equipment and saves construction costs; compared with other methods of manually lowering the reinforcement cage, This method requires only two workers to complete the binding and lowering of the reinforcement cage, and uses four U-shaped slots to provide four support points for the reinforcement cage, ensuring the balance and stability of the lowering of the reinforcement skeleton.

Embodiment 1

[0029] A device for manually lowering the overweight steel cage of digging piles. The structure of the device is as follows image 3 Shown: Two pressure-bearing pipes 2 and two connecting pipes 3 are connected together by four sleeves 4 to form a square frame, which is placed on the pile foundation reinforced concrete wall 1; four U-shaped slots 6 are welded symmetrically The first reinforcing stirrup 7 of the steel cage, one side of the slot 6 is welded to the longitudinal main reinforcement 8 of the steel cage, and a reinforcing steel bar 10 is welded to the adjacent slot 6; two nylon ropes 5 are respectively passed through One end of the two U-shaped card slots 6 is fixed to a pressure tube 2 and the other end is fixed to the other pressure tube 2 by a slip knot.

[0030] Both the pressure-bearing pipe 2 and the connecting pipe 3 use steel pipes with a diameter of 83 mm. The length of the pressure-bearing pipe 2 is greater than the diameter of the reinforced concrete protective...

Embodiment 2

[0036] Such as figure 1 As shown, the depth of the excavated pile is 20m, and the height of the reinforced concrete wall 1 is 0.5m~1m. The design requirement is to tie a 2m steel cage to one section, and then lower it for 2m until the steel cage reaches the designed height.

[0037] A method for manually lowering the overweight steel cage of digging piles includes the following steps:

[0038] Step 1, such as figure 1 As shown, to make a square steel tube frame, prepare four steel tubes with a diameter of 83mm, two of which are pressure-bearing pipes 2 longer than the diameter of the reinforced concrete wall 1, and the other two lengths are slightly smaller than the diameter of the reinforced concrete wall 1 for connection Tube 3, cut the ports of the four casing pipes 4 into inner arcs and divide them into two pairs. The ends of each pressure-bearing pipe 2 are welded symmetrically with a pair of casing pipes 4, and then the connecting pipe 3 is inserted into the casing pipe 4, Th...

Abstract

The invention discloses a method for manually lowering an overweight reinforcement cage of a hole digging pile. The method comprises the steps that a steel-tube square frame is manufactured; U-shaped necks are arranged, a first stiffening hoop is manufactured, and longitudinal main reinforcements of the reinforcement cage are welded to the first stiffening hoop; nylon ropes are fixed on the steel-tube square frame, and the first section of the reinforcement cage is horizontally placed on the nylon ropes; the first section of the reinforcement cage is gradually bound upwards; lowering is conducted on the reinforcement cage through the nylon ropes on the lower portion; the next section of the reinforcement cage is bound continuously till the bottom of the reinforcement cage reaches the designed depth. According to the method for manually lowering the overweight reinforcement cage of the hole digging pile, the problems that the lifting range of hoisting equipment is difficult to cover the pile foundation position, the hoisting equipment is difficult to be in place, the hole digging pile is blocked by inner support beams over the hole digging pile, and the reinforcement cage can not be lowered or is difficult to lower are solved, two workers are only needed to complete manufacture and lowering of the reinforcement cage, and the engineering cost is reduced.

Description

Technical field [0001] The invention relates to the field of pile foundation construction in the construction industry, and in particular to a method for manually lowering the overweight steel cage of digging piles, and is suitable for manually binding and lowering the steel cage of the digging pile at the construction site. Background technique [0002] Under normal circumstances, the reinforcement cage is hoisted by lifting equipment and lowered and installed in the pile foundation after the tying is completed in the factory or on-site. However, in actual construction, it often happens that the lifting equipment cannot be parked on site or the lifting equipment The hoisting range cannot cover all pile foundation positions, etc., and it is impossible or difficult to lower the steel cage. Summary of the invention [0003] The purpose of the present invention is to provide a method for manually lowering the overweight steel cage for digging piles, which solves the situation that th...
