Problems solved by technology

[0003] When pouring concrete for the pile core, it is necessary to seal the gap 7 between the prefabricated pile cap 3 installation hole and the outer wall of the steel pipe pile 2. Formwork is often used on site for support, but the efficiency of formwork support is low and the construction is affected by moisture. Restrictions, which seriously affect the progress of the installation

Embodiment 1

[0037] combine image 3 , Figure 4 , Figure 5 and Image 6 As shown, a method of processing the bottom cover hoop for the construction of an assembled pile cap, through the following steps:

[0038] 1) Mold selection

[0039] The cut steel pipe pile head is used as the mold for the hoop processing, and the straight pile is used directly; the incision of the inclined pile head is ground and smoothed, and the supporting steel bar 8 required in the hoop processing process is welded, and the supporting steel bar 8 is Ø12mm* 10cm;

[0040] 2) Selection of hoop material

[0041] In order to ensure that the hoop is easy to bend, the material of the hoop is 3mm thick thin steel plate 9, the straight pile hoop needs to be cut into a 10cm wide thin steel strip, and the inclined pile hoop needs to be cut into a 33cm wide thin steel strip;

[0042] 3) hoop processing

[0043] Place the long side of the thin steel plate 9 around the hoop to process the mold and place it on the mol...

Abstract

The invention discloses a machining method of a bottom sealing hoop for fabricated pile cap construction. The method includes the steps of (1) selecting a mould; (2) selecting a hoop material; (3) machining the hoop; (4) selecting an annular blocking plate material and discharging; (5) welding an annular blocking plate; (6) welding connecting bolts and cutting; and (7) stopping gouting. Accordingto the machining method of the bottom sealing hoop for fabricated pile cap construction, when the bottom sealing hoop is applied to assembly type pile cap construction, the bottom sealing hoop is convenient and efficient to install (12 sets of bottom sealing hoops can be installed in a single set every day and under the condition that the bottom sealing hoop is affected by damp levels), and the grout stopping effect is good.

Description

technical field [0001] The invention relates to a processing method for a bottom-sealing hoop used in the construction of an assembled pile cap. Background technique [0002] At present, in the construction of supporting wharf projects for coal-fired power plants, the oil product, heavy cargo wharf, and coal unloading wharf all adopt high-piled beam-slab structures, such as figure 1 As shown, the lower structure is steel pipe pile 2; the upper structure is mainly prefabricated and installed, including prefabricated pile cap 3, prefabricated longitudinal beam 4 (or prefabricated ship berth member 1), prefabricated panel 6 and cast-in-place surface from bottom to top Layer 5 etc. Among them, the prefabricated pile cap 3 is to bury four φ32mm supporting steel bars during prefabrication, and the supporting steel bars are located on the top of the steel pipe pile 2 during installation. After the position and elevation of the pile cap are adjusted, it can be welded and fixed. li...
