Building foundation pit drainage system and drainage structure thereof
A building foundation pit drainage system and a drainage structure thereof relate to the technical field of building foundation pit drainage, the drainage structure comprises a building foundation pit, a water channel is arranged around the bottom of the building foundation pit, a water collecting well is arranged in the water channel, the water collecting well comprises a main body, and guard plates are arranged in front and back of the main body. The main body, the front guard plate and the rear guard plate form a water collecting well, the main body, the front guard plate and the rear guard plate form deposition chambers with upward openings on the left side and the right side of the water collecting well, a sieve plate I is arranged in each deposition chamber, and a filter layer composed of gravel is laid above each sieve plate I. The building foundation pit drainage system and the drainage structure thereof have the advantages that the air valve is started to intermittently ventilate into the air chamber; then the volume of the air chamber is changed, the water in the deposition chamber is driven to sink and float up and down in a pulse mode, the gravel in the filter layer is driven to sink and float up and down, the water in the deposition chamber sinks and floats up and down to wash silt and gravel blocked in the gravel filter layer, and then the silt and gravel in the gravel filter layer are deposited in the deposition chamber; therefore, the problem of slow drainage caused by clogging of the gravel block filter layer is avoided.
一种建筑基坑排水系统及其排水构造，涉及建筑基坑排水技术领域，其排水构造包括建筑基坑，建筑基坑坑底四周设有水渠，水渠内设置有集水井，集水井包括主体，主体前后均设有护板，且主体与前后护板在集水井左右两侧均构成了开口向上的沉积室，沉积室内设有筛板一，筛板一上方铺设有由碎石组成的滤层，本发明提供了一种建筑基坑排水系统及其排水构造，通过启动风阀间歇性的向空气室内通气，进而使得空气室体积变化，进而带动沉积室内的水上下脉冲沉浮，进而带动滤层内的碎石块上下沉浮，沉积室内的水上下沉浮脉动对碎石块滤层内淤堵的淤泥砂石进行冲刷，进而使得其内的淤泥砂石沉积在沉积室内，进而避免了碎石块滤层淤堵导致排水缓慢的问题。
