Embodiment 1
[0044] Embodiment 1: a kind of production technology of pipe pile, specifically comprises the following steps:
[0045] Step 1: Prepare concrete, dry and mix Portland cement, medium sand, fly ash, mineral powder, and stones, then add water and water reducing agent for mixing to obtain concrete for later use;
[0046] Step 2: Make the pipe pile skeleton, cut prestressed PC steel rods of equal length, fix multiple prestressed PC steel rods on the pier head of the seam welder, run the seam welder, and seam weld the spiral ribs on the prestressed PC On the steel bar, the two ends of the spiral reinforcement on the prestressed PC steel bar are contracted sections with a pitch of 45 mm, and the rest are extended sections with a pitch of 80 mm, and the length ratio of the contracted section to the extended section is 1:10, so that the pipe pile skeleton is obtained ;
[0047] Step 3: Assembling and loading the mold, disassembling the pipe pile mold into upper and lower half molds, h...
Embodiment 2-5
[0055] Embodiment 2-5: A production process of pipe piles. The difference from Embodiment 1 is that the components of the concrete and their corresponding parts by weight are shown in Table 1.
[0056] Each component of concrete and parts by weight thereof in Table 1 Embodiment 1-5
[0057]
[0058]
Embodiment 6
[0059] Embodiment 6: A production process of pipe piles. The difference from Embodiment 1 is that step 5 is specifically set as centrifugal molding, and the pipe pile mold after pouring into a mold is hoisted to a horizontal centrifuge for high-speed rotation. First keep the speed at 200rpm, run for 15min, then keep the speed at 500rpm, run for 15min, finally keep the speed at 300rpm, run for 12.5min, after standing for 10min, filter the slurry water in the pipe pile mold with a filter bag, and collect In the water storage tank, sample water 1 was obtained and stored for later use.

Abstract
The invention discloses a production process of a pipe pile, and relates to the technical field of concrete component processing. The production process solves the problems that in the production process of the pipe pile, waste of energy is easily caused due to unreasonable process design, thereby the poor overall industrial applicability is caused. The pipe pile with high compactness, good strength, good stability and excellent performance is prepared by preparing concrete, making a pipe pile skeleton, conducting splicing and mold entering, conducting pouring mold forming, conducting centrifugal forming, conducting steam curing and conducting high pressure steaming. Meanwhile, in the preparation process, steam curing and high pressure steaming are adopted, the production cycle is greatlyshortened, the production efficiency is better improved, water in centrifugal molding and steam curing is collected, first sample water and second sample water are obtained, then the first sample water and the second sample water are used for cooling a sample of the pipe pile in high pressure steaming, at this time, third sample water at higher temperature is collected, the water can be recycled in a steam cabinet and a high temperature steam furnace, energy and resources are better saved, and the good applicability is achieved.
Description
technical field [0001] The invention relates to the technical field of concrete component processing, more specifically, it relates to a production process of pipe piles. Background technique [0002] The role of pipe piles is to transfer the load of the superstructure to the deep soil layer with strong bearing capacity, or to compact the soft soil layer to improve the bearing capacity and compactness of the foundation soil. It is mainly used in railways, industry and civil use Construction, municipal, metallurgy, ports, highways and other fields. [0003] In the Chinese invention patent whose application publication number is CN108081447A, a production process of pipe piles is disclosed, which includes the following steps: mixing and stirring, preparation of reinforcement cages and moulds, pouring, centrifugal maintenance: after stretching is completed, the pipe pile molds are placed Put it on a horizontal centrifuge; stop for 25-35 minutes after centrifugation, put it int...
