Embodiment 1
[0046] A support assembly for pile filling, including a main beam, a secondary beam, a slab and an A-shaped brace. There are multiple main beams and secondary beams, and the multiple main beams are arranged in parallel on the first concrete support beam, and the secondary beams It is arranged between two adjacent main beams, the slab is laid on the top of the main beams, and the two ends of the A-shaped brace are respectively connected to the first concrete support beam and the second concrete support beam.
[0047] In this embodiment, a column is also included, and the two ends of the column are respectively connected to the first concrete support beam and the second concrete support beam.
[0048] In this embodiment, HM582x300x11x15, I-beam with strength grade of Q355 is used as the main beam,
[0049] In this embodiment, channel steel with 16a strength grade of Q235 is used as the secondary beam,
[0050] In this embodiment, 250*250*10 square steel with a strength grade of...
Embodiment 2
[0053] Such as figure 1 Shown, show a kind of method for supplementing piles, comprising the following steps:
[0054] S1, measurement and setting out;
[0055] S2, buried casing;
[0056] S3, placing the main beam, and setting the main beam on the first concrete support beam in parallel;
[0057] S4. Place the secondary beam and the slab, arrange the secondary beam between two adjacent main beams, and lay the slab above the main beam;
[0058] S5, install the A-shaped brace, connect the two ends of the A-shaped brace to the first concrete support beam and the second concrete support beam respectively;
[0059] S6. Carry out pile filling operation on the flat plate.
[0060] In this embodiment, step S3 includes: placing a main beam every 1-1.2m, and popping up the main beam placement position on the top of the crown beam with a gray line or ink line, placing a 10mm steel plate in the center of the main beam and installing the steel plate through expansion bolts. Fixed on th...
Embodiment 3
[0064] In a specific embodiment, a pile filling method comprises the following steps:
[0065] Step 1, measuring and setting out
[0066] Use GPS or total station to locate the pile position in the trestle bridge and foundation pit. The error of any direction of the pile position is not more than 20mm. After confirmation, mark the pile position with obvious markers.
[0067] Step 2. Embedding the casing
[0068] When hoisting the steel casing, use the 80T truck crane to lift the steel casing through the single-point hoisting method of the wire rope to feed the piles. When inserting the piles, the pile heads must be aligned with the pile position markers on the ground, and two theodolites are crossed at 90° Observe the verticality at the place where the full length of the pile can be clearly seen, and ensure that the verticality of the first section shall not exceed 0.5%, and the verticality of the remaining sections shall not exceed 1%. The verticality of the pile in the fir...
