Description

Modularized assembled concrete channel system suitable for steep hillside fields Technical Field The invention relates to the technical field of hydraulic engineering and slope treatment, in particular to a modularized assembled concrete channel system suitable for steep hillsides. Background When agricultural irrigation, water conservancy allocation or drainage flood control are carried out in mountainous areas, hills and other areas, water delivery channels are often required to be built on steep hills. The traditional abrupt slope channel mostly adopts a construction mode of site formwork support and on-site concrete pouring, and the mode has a plurality of defects that firstly, under the steep and rugged mountain land, formwork support, concrete transportation and pouring construction are extremely difficult, the efficiency is low, the safety risk is high, the requirement on site flatness is high, large-scale excavation and support are often needed, and the damage to the original ecological environment is large. Secondly, the cast-in-place concrete structure is integral, has poor adaptability to uneven settlement of the foundation, is easy to crack, leak and even structural damage due to foundation deformation on the steep unstable foundation, and is very difficult to maintain and maintain. In order to overcome the defects of the cast-in-situ technology, the prefabricated channel technology is applied to a certain extent. However, under the special working condition of steep hills, the common prefabricated channel module still faces serious challenges: 1. The problem of overall stability is that the common prefabricated modules are generally connected by adopting simple socket joint or flat joint, the connection strength is limited, the integral downward sliding force of the channel on the steep slope is difficult to be effectively resisted, and the risk of integral instability exists. The joint seepage-proofing reliability problem is that the joint between the modules is a seepage-proofing weak link. Under the condition that the abrupt slope foundation is likely to be slightly deformed, the traditional joint treatment mode is easy to fail, so that leakage is caused, water resource waste is caused, and more serious, the leakage water can erode the canal foundation, so that the slope instability is further aggravated. The foundation adaptability is poor, the common prefabricated components have higher requirements on the foundation, and the steep foundation is hard and uneven, or a local weak area exists, so that the components are difficult to install, the stress is uneven, and the line shape and the service life of a channel are affected. Therefore, a channel system specially designed for steep slope hills is urgently needed, and the channel system must have the characteristics of convenience in construction, rapid assembly, firm connection, seepage prevention reliability, and effective adaptation and resistance to potential deformation and slippage risk of steep slope foundations.
