A water supply joint adjustment system for bridge piers and abutments

Abstract

The invention discloses a water supply joint adjustment system for piers and abutments, which consists of water control equipment, a water supply bag, a reversing device, a water supply main pipe, a pipeline pressure relief valve, a pipeline booster pump, a safety valve, a water tank, and a water pump , suction pump guide pipe, river water filter valve, river water, drain pipe, mixed water control valve, mixed water main pipe, return water main pipe, reversing device, and return water bag are sequentially connected in a closed loop to control the cooling water inside the pier abutment concrete At the same time, the temperature meets the external water storage and heat preservation requirements. Between the water supply and the return water main pipe, the cooling water return water is used twice through the water mixing main pipe, and the return water is introduced into the water tank. By returning the higher temperature cooling water and the lower temperature The temperature of the water in the water tank can be adjusted by controlling the opening of the mixed water control valve, so that it can be used for external water storage and heat preservation of concrete or internal water cooling. By adopting this method, the risk of cracking of the pier abutment concrete can be reduced.

Description

【Technical field】 [0001] The invention belongs to the field of concrete temperature control and anti-cracking of piers and abutments, and in particular relates to a water supply joint adjustment system for bridge piers and abutments. 【Background technique】 [0002] During the construction of road and bridge projects, due to the influence of internal hydration heat, the large-volume concrete structure of bridge piers and abutments usually causes relatively large temperature stress. and external water storage insulation and other temperature control measures. [0003] However, there is a lack of relevant research on the water supply system for the internal water cooling of the pier abutment concrete and the external water storage and heat preservation water in the existing technology, which often leads to the fact that the actual water supply does not meet the temperature control requirements, which in turn causes a large internal and external temperature difference leading to...
