The drainage of rockery production is crucial. If not properly treated, water will leak out and penetrate into the interior of the rockery, affecting its structure. Additionally, it will rust the steel structural components inside the rockery, so drainage pipelines must be well prepared. The drainage in rockeries generally adopts the form of dredging to discharge excess rainwater and avoid rainwater accumulation. It is a commonly used drainage tool for drainage pipelines.

假山中的排水管道分三種：

There are three types of drainage pipes in rockeries:

槽型排水管道，這種管道通常是以凹槽的形式架設在假山的頂部，一方面為了美觀我們通常是做嵌入式的布局常使用在鋼結構的假山上，主要注意點就是鋪設的時候要注意倒流方向和高度，定期檢查訪問雜物堵塞通道。

Trough type drainage pipes are usually installed in the form of grooves on the top of rockeries. On the one hand, for the sake of aesthetics, we usually use embedded layouts on steel structure rockeries. The main point of attention is to pay attention to the direction and height of the backflow when laying, and regularly check for debris blocking the passage.

排水孔型排水系統，通過在假山低端做一個排水孔，污水和雨水通過假山面層透過排水孔自然排出，這種通常用于假山結構中，注意點就是排水孔的選擇位置一定要合理，不然會導致積水甚至壓壞假山面層的上部。

The drainage hole type drainage system is designed by creating a drainage hole at the low end of the rockery. Sewage and rainwater are naturally discharged through the drainage hole through the surface layer of the rockery. This type of drainage hole is usually used in rockery structures. The point of note is that the location of the drainage hole must be reasonable, otherwise it may cause water accumulation or even damage to the upper part of the rockery surface layer.

逆流式排水系統，這種屬于比較現金模式的排水系統，通過在假山關鍵位置安裝的逆風通流系統把雨水和污水統一吸入到污水槽中排向地面，排水率最高。

A countercurrent drainage system, which belongs to a relatively cash based drainage system, uses a countercurrent flow system installed at key locations on the rockery to uniformly suck rainwater and sewage into the sewage tank and discharge them to the ground, with the highest drainage rate.
