（9）砼灌注：砼灌注前加隔水塞（止水球），保障混凝土灌注质量。
① 设备
导管： 底部 直径φ219 长度3.5m
中间 直径φ219 长度2.5m×n
上部 直径φ219 长度1m×n+0.5m×n
料斗：容积1立方
② 第一次砼灌连续注量计算
在第一次连续灌注混凝土之后，埋管深度必须保证至少1m。
第一次连续灌注最少量计算如下（以有效桩长27m，孔深34m为例）：

(9) concrete grouting: Before concrete casting plus Water Stopper (sealing ball) to ensure the quality of concrete pouring.
① equipment
catheter: base diameter φ219 length 3.5m
intermediate diameter φ219 length 2.5m × n
upper diameter φ219 length 1m × n + 0.5m × n
hopper: Volume 1 cubic
② first concrete pour continuous injection amount calculated
for the first time in a row after the pouring of concrete, pipe depth must ensure that at least 1m.
The first continuous infusion minimum amount is calculated as follows (in effective length 27m, 34m deep hole as an example):
