Description

Bridge construction pier body production process Technical Field The invention belongs to the technical field of bridge engineering, and particularly relates to a production process of a bridge construction pier body. Background Generally, the pier structure includes an upper coping and a lower pier body, the former is required to be connected to a bridge, and the latter is required to be connected to the ground. The structural components of the pier body mainly comprise a steel bar net cage and concrete, so that the quality of a concrete pouring process directly influences the structural strength of the pier body. The existing common pier body pouring production process mainly comprises the following steps of pouring concrete into a lowest vibrating layer, vibrating a vibrating rod to uniformly mix the concrete, pouring a new layer of concrete, and repeating the vibrating operation for a plurality of times, so that a complete pier body product can be obtained. The process has the advantages that the concrete pouring and vibrating operation are relatively simple and convenient, the time limit is not provided, the concrete can be fully vibrated, and the concrete can be temporarily stopped and adjusted at any time. However, the defects are more remarkable, namely the overall construction period is relatively long, the allowable air inlet time in the concrete is long, and the curing degree difference between each vibrating layer is large. Finally, the appearance color difference is larger, the bubbles are increased, the integrity of the pier body structure is poor, and the strength is insufficient. Thus, improvements in the overall concrete placement and vibration process are now desired. For example, the Chinese patent publication No. CN108425322A, publication No. 2018.08.21 discloses a method for setting a vibration channel for pouring concrete on a No. 0 block of a continuous beam, wherein the method comprises the steps of firstly arranging a vibration hole, secondly arranging a string cylinder, thirdly presetting the vibration channel, and fourthly constructing concrete. According to the setting method in the patent, vertical and oblique vibrating channels are uniformly arranged, so that the vibrating is performed in all directions, dead angles are not remained, the full coverage of the concrete at the bottom of the beam and near the support is realized, and the quality of the concrete is ensured. However, the concrete pouring and vibrating method is only started from the vibrating mode, the primary and relatively secondary vibrating sufficient degree is improved, and the pouring structure integrity of the bridge pier can not be greatly improved. On the other hand, for the pouring operation and the vibrating operation of the concrete, the necessary operation auxiliary device is also lacked, and the stability and convenience of the concrete pouring vibrating mode are ensured. Therefore, in summary, a new pouring and vibrating process based on the auxiliary device for concrete pouring and vibrating operation is urgently needed at present, so as to ensure that the bridge pier body after construction has larger structural strength. Disclosure of Invention The invention provides a bridge construction pier body production process, which can be used for realizing a continuous concrete pouring and vibrating process by firstly setting scale marks of a pipe body fixing frame and a vibrating rod hose, then plugging a concrete pouring hose and a vibrating rod hose, and then upwards lifting the concrete pouring hose and the vibrating rod hose in a matched manner, so that few bubbles in the pier body, good structural integrity, larger strength and relatively smaller appearance color difference are ensured. In addition, the invention also provides a pipe body fixing frame used in the concrete pouring and vibrating process, which structurally comprises a bottom plate, U-shaped steel, a middle circular ring unit, side bottom plate units and a support rod unit, so that the continuous concrete pouring and vibrating process is more stable and convenient, and in addition, the vibrating rod hose is not easy to bend and damage during lifting. The technical scheme adopted for solving the problems is that the production process of the bridge construction pier body sequentially comprises the following steps: S1, arranging a pipe body fixing frame on the upper edge of a pier body template, and arranging scale marks corresponding to the depth of a vibrating layer on the outer ring surface of a vibrating rod hose; S2, splicing a concrete pouring hose and the vibrating rod hose on the pipe body fixing frame; S3, starting the concrete pump truck and the vibrating bars, so that the concrete pouring hose is used for continuously pouring concrete and lifting upwards, and the vibrating bar hose is intermittently lifted upwards, so that concrete vibrating operation of the vibrating bar body at the corresponding depth of all vibrating layers
