Behaviors Analyses And Research Of Septic Tank Of Arched Brickwork

Masonry structure is one of ancient structures for its handy material, and shell structure is also widely used in our country because of its good force performance. Brick shell structure has merits of both structures, so it is widely used in roof systems and floor systems from 1960 to 1970. Septic tank, as auxiliary project in body-building and one of the main equipments in treating domestic sewage and industrial wastes, can not be neglected in construction and development of the cities. How to make use of the function of septic tank effectively and sufficiently and improve its efficacy , Zhu Li-Pei ,who is a Sr. engineer in Hunan Engineering College ,has done in-depth research basing on traditional septic tank and invented the single well and multi-partition septic tank of arched brickwork and also applied the patent.Compared with traditional three-well septic tank, the single well and multi-partitioned septic tank of arched brickwork without forms have advantages as follows:1. The single well and multi-partitioned septic tank of arched brickwork without forms utilizes the good behavior of birdcage's compressive, which makes the structure have better behaviors.2. The techniques molding of the single well and multi-partitioned septic tank of arched brickwork without forms does not need any form, and the technique is simple, and task period is short, and it can save material.3. When the foundation ditch is excavated, single well and multi-partitioned septic tank of arched brickwork without forms needs not supported for its circle pool and circle pit, and the landslide hardly generate, so the cost is saved.4. The single well and multi-partitioned septic tank of arched brickwork without forms has only one hole mouth, the probability of losing cover leading to people hurt can be apparently reduced. If peradventure it happens, there is "tee" partitions which can prevent people's fallen and to climb.5. The single well and multi-partitioned septic tank of arched brickwork without forms has only one hole mouth exposed to ground.6. The layer of earth on septic tank can provide more space for landscaping, so this is environmental and more economical and social value is better.This study which bases on summarizing primary research of the single well and multi-partitioned septic tank of arched brickwork without forms completes works as follows:1. The practicability of this project is demonstrated.2. Applying thin shell theory, choosing reasonable sectional dimension and adopting...
