目前，桥梁桩基施工多为灌注水下混凝土，虽然灌注水下混凝土已经过多年的经验积累和总结，但施工过程中不为人预知的事故还是经常发生，大到断桩，小到浮笼等，给施工带来影响并造成经济损失。
一、剪球时卡管
在灌注水下混凝土时，经常会产生剪球时卡管的情况，出现这种情况的原因有两个。
1、剪球制作不合理
塞球直径与导管直径差别太小，剪球前由于砂浆或细石料渗入导管与球壁之间造成堵塞。如果是这种情况，在不浪费混凝土方量的前提下，应急处理办法有两个：
⑴ 用一定长度（一般比漏斗长2m左右）直径为20mm～25

Key words: underwater concrete Accident At present, the Construction of the Bridge over the pouring underwater concrete, although the underwater concrete has been many years of experience and lessons, but the man did not predict the course of construction accidents or frequent, large broken piles, floating cage, etc. small to affect the construction and cause economic losses. First, cut the ball tube in the pouring underwater concrete, we often will have cut the ball tube in the case, this occurs for two reasons. 1, cut the ball making unreasonable Cypriot vessel diameter, ball diameter and the difference is too small, cut the ball or small stone mortar ago because of infiltration of the wall the ball between the catheter and cause blockage.

Abstract: The underwater concrete cast in the event of an accident, should take appropriate measures to prevent accidents as much as possible to expand or to loss of control to a minimum. This article on the possible accident analysis and the corresponding approach.

Key words: underwater concrete Accident
At present, the Construction of the Bridge over the pouring underwater concrete, although the underwater concrete has been many years of experience and lessons, but the man did not predict the course of construction accidents or frequent, large broken piles, and other small floating cage , to the construction impact and cause economic losses.
First, cut the ball card management
Underwater concrete is poured, the ball often produce cutting tube in the case, this occurs for two reasons.
1, cut the ball making unreasonable
Seven ball diameter and vessel diameter difference is too small, cut the ball or small stone mortar ago because of infiltration of the wall the ball between the catheter and cause blockage. If this is the case, the parties do not waste the amount of concrete under the premise of the contingency approach are two:
⑴ with a certain length (usually longer than the funnel around 2m) diameter 20mm ~ 25
