Description
本实用新型涉及围堰领域,具体来说是一种用于胶结卵石地质的锁扣钢管桩围堰。
围堰:是指在水上工程建设中,为建造永久性水上设施,修建的临时性围护结构。
围堰种类较多,在水较深且流速较大的河流一般采用钢管桩围堰;现有钢管桩围堰在大多数环境下都可以顺利施工的,但是对于一些特殊河床,在施工时就会具有一定的问题。
特别是河床地质为胶结卵石地质的河流,因为胶结卵石地质的河床中砂卵石较多,在钢管桩进行插打时,不能顺利插打到位,而钢管桩插打不到位会影响围堰整体结构的稳定性,同时影响工程建设。
所以为了解决上述问题,会增加清基次数,一般是初始清基后,再次进行二次清基,继而保证钢管桩能够插打到位,使得围堰施工能够顺利。
但是在围堰二次清基时,因为围堰内外压力变化较大,围堰会在外部的挤压力的作用下发生较大形变,继而影响围堰的后续继续使用。
所以为了保证围堰二次清基时的稳定性,就需要对现有围堰结构进行优化设计。

具体,本实用新型公开的围堰辅助支撑机构3主要是包括支撑梁31,支撑梁31起到一个侧向支撑作用,通过配合钢护筒2实现对围堰内壁的支撑,从而保证围堰1二次清基时因为围堰外部受力较大而发生较大的形变。
具体使用时,支撑梁31一端连接在围堰1内部,可以根据需要连接在钢管桩结构11上,另一端抵压在钢护筒2上,通过钢护筒2的限位作用,从而实现支撑梁31位置的限定,从而使得钢护筒2可以对围堰1边缘进行支撑,保证围堰1在二次清基时的结构稳定性。
进一步的,在本发明中所述钢管桩结构11内还设有圈梁结构12,所述圈梁结构12包括第一层圈梁121、第二层圈梁122以及第三层圈梁123;所述第一层圈梁121、第二层圈梁122以及第三层圈梁123在钢管桩结构11内部由上至下依次间隔分布;所述围堰辅助支撑机构布置在第一层圈梁121上方;圈梁结构12设置,可以很好的保证对钢管桩结构11的支撑作用,保证围堰整体结构的稳定性性。
另外,在实际使用时,上述围堰辅助支撑机构可以在围堰内未设置圈梁结构12时进行使用,使得围堰辅助支撑机构充当圈梁实现对围堰内部的支撑,保证围堰结构整体结构的稳定性,保证二次清基的顺利进行,在圈梁结构12布置完成后,围堰辅助支撑机构可以根据需要进行拆除。
进一步的,在本发明中所述钢管桩结构11内部设有支撑牛腿5,这里支撑牛腿5就是一个架设梁结构,主要是用于支撑圈梁结构12,保证圈梁结构12在围堰内部的悬放;在实现对钢管桩结构11内部支撑;属于现有技术,这里不再赘述,另外,在本发明中所述支撑牛腿5连接在钢管桩结构11中的一个或者多个锁扣钢管桩111上;在连接有支撑牛腿5的锁扣钢管桩111内设有吊模混凝 土1-1;吊模混凝土1-1的设置,可以增加锁扣钢管桩111的结构强度,保证支撑牛腿5连接在钢管桩结构11上的稳定性。
进一步的,在本发明中所述钢管桩结构11底部设有封底混凝土层4;封底混凝土层4可以在底部对钢管桩结构11底部进行侧面支撑限位,在一定程度上增加了围堰的整体结构强度,同时可以配合圈梁实现钢管桩结构11的内部支撑,同时也方便后续承台和拱座的设置。
进一步的,在本实用新型中所述支撑梁31靠近钢护筒2一端设有辅助部32,所述辅助部32包括设置在支撑梁31上的支撑板321,所述支撑板321一端设置在支撑梁31上,另一端与钢护筒2相贴合;辅助部32的设置,增加了围堰辅助支撑机构3与钢护筒2之间的接触区域,从而很好的保证了围堰辅助支撑机构3对围堰1的支撑;具体,辅助部32包括设置在支撑梁31上的支撑板321,支撑板321的设置,相当于增加了支撑梁31靠近钢护筒2一端的横向尺寸,增加了围堰辅助支撑机构3与钢护筒2之间的接触面积,从而很好的保证了围堰辅助支撑机构3对围堰1支撑的稳定性;同时支撑板321相当于加强肋,可以很好的保证围堰辅助支撑机构3端部的结构强度。
进一步的,在本实用新型中所述支撑梁31上设有两个辅助部32,两个所述辅助部32对称分布在支撑梁31的两端;本实用新型采用这样的布置,可以保证围堰辅助支撑机构3与钢护筒2之间连接的稳定性,避免围堰辅助支撑机构3对钢护筒2之间施加的力偏移,使得围堰辅助支撑机构3与钢护筒2之间发生相对滑动的问题。
进一步的,在本实用新型中所述支撑板321倾斜布置;所述支撑梁31的中轴线经过钢护筒2的圆心点;所述支撑梁31垂直与支撑梁31所连接的围堰1侧壁;本实用新型通过这样的布置,可以使得支撑梁31和支撑板321的配合相 当于一个弧形卡爪卡接在钢护筒2上,很好的保证了围堰辅助支撑机构3与钢护筒2之间连接的稳定性,基本避免了围堰辅助支撑机构3侧面滑脱钢护筒2的问题。
进一步的,在本实用新型中所述支撑板321与钢护筒2贴合区域设有弧形槽322;通过弧形槽322的设置,并且要求弧形槽322与其接触的钢护筒2的外侧面弧度相同,这样的布置方式,增加了支撑板321与钢护筒2之间的接触面积,很好的保证了支撑板321与钢护筒2之间连接的稳定性;同时为了保证支撑梁31与钢护筒2之间的连接稳定性,在支撑梁31端部也设有弧形沉槽结构,这样设置的方式,可以方便支撑梁31贴合抵压在钢护筒2外侧。
进一步的,在本实用新型中所述弧形槽322内设有支撑垫323;支撑垫323可以是橡胶垫也可以是防滑材料制成的防护垫,支撑垫323一个作用是避免支撑板321与钢护筒2之间的刚性碰撞,另一个作用是增加支撑板321与钢护筒2只之间的摩擦力,保证支撑板321与钢护筒2之间的连接的稳定性。
显然本实用新型具体实现并不受上述方式的限制,只要采用了本实用新型的方法构思和技术方案进行的各种非实质性的改进,均在本实用新型的保护范围之内。
