Description
Technical Field
The utility model belongs to the technical field of test instrument equipment of test prestressed concrete raw material performance among the public road bridge beam engineering, especially, relate to a but anti seepage capability test device in crooked back of loading and unloading portal frame formula metal bellows.
Background
The metal corrugated pipe is widely applied to bridge engineering as a common prestressed pore-forming material for prestressed concrete. The post-tensioning method is a method commonly used in bridge prestressed concrete, and the main process is to pour concrete firstly, then stretch the reinforcing steel bars through a pore channel reserved in the concrete, and pour grout for sealing the anchor, wherein the reserved pore channel usually adopts a metal corrugated pipe. In the bridge prestressed concrete, the metal corrugated pipe is usually arranged in a bending mode according to a certain radian, and then the prestressed reinforcement can be guaranteed to be capable of keeping a certain bending radian. After a certain bending, the metal corrugated pipe also puts certain requirements on the anti-leakage performance of the metal corrugated pipe, because the metal corrugated pipe is related to the quality of pore-forming grouting. The slurry is used as the last protective barrier of the prestressed reinforcement in the prestressed concrete structure, if the corrugated pipe has defects, the anti-leakage performance is poor, on one hand, cement slurry cannot fill the whole corrugated pipe, so that the top of the corrugated pipe has larger crescent gaps, and even has the phenomenon of rib leakage; on the other hand, the strength of the grouting body is not enough, so that the grouting body, the steel strand and the concrete cannot form a unified whole, and the prestress can be lost in advance, so that the service life of the bridge is shortened.
The existing industry standard 'prestressed concrete metal corrugated pipe' (JG 225-2007) clearly proposes a test of the leakage resistance of the bent metal corrugated pipe, but does not clearly indicate what kind of device is used for the test, so that a unified standard is not available during the execution. The chinese patent "metal corrugated pipe leakage resistance test device" (published as 2014-12-24 in patent No. 201420338253.5) proposes that trolleys which can move linearly in the horizontal direction of a support are uniformly distributed, a "v-shaped support" for supporting different pipe diameters is arranged at the front end of each trolley, and the metal corrugated pipe is bent by controlling the trolleys to run to corresponding positions. However, the device involves many parts such as a computer, a cable, a power supply, software, a trolley and the like, and although the idea is feasible, the device has high cost, complex operation and insufficient convenience. Meanwhile, the device only aims at the round metal corrugated pipe, and does not consider the flat metal corrugated pipe. Due to the factors, the device is difficult to popularize and apply.
