Underwater concrete sampler

水下砼取样器

Abstract

本实用新型涉及一种用于判断钻孔灌注桩的桩顶是否达到标高位置的水下砼取样器。其特征在于包括两端开口的储料筒,导杆通过连接块连接在储料筒的上端,两块固定板设置在储料筒内接近下端处的两侧,两个对开的活动板分别铰接在储料筒内与固定板等高处,活动板对开处于储料筒的内侧壁上设有支撑活动板的支撑块,活动板后的储料筒侧壁上设有限位杆。本实用新型结构简单,制造成本低,操作方便,可方便、准确地在水下混凝土灌注桩设计标高处取样,并判断水下灌注混凝土面是否已达到设计标高,减少因超灌而造成的混凝土浪费及劳动力成本的浪费,降低施工成本,加快施工进度。
The utility model relates to an underwater concrete sampler used for judging whether the top of a bored pile achieves an elevation position. The underwater concrete sampler is characterized by comprising a storage barrel with two ends equipped with openings, wherein a guide rod is connected to the upper end of the storage barrel through a connecting block, two fixing plates are arranged on two sides of a position inside the storage barrel approaching the lower end thereof, two opposite moving plates are respectively hinged at a position with height equal to that of each fixing plate inside the storage barrel, supporting blocks for supporting the moving plates are arranged on an inner lateral wall of the storage barrel equipped with the moving plates, and a limit rod is arranged on the lateral wall of the storage barrel at the rear of the moving plates. The underwater concrete sampler is simple in structure, low in manufacturing cost and convenient in operation, can conveniently and accurately sample at a designed elevation position of an underwater concrete cast-in place pile, and judges whether an underwater cast-in place concrete surface achieves the designed elevation position or not, thereby reducing concrete waste and labor cost waste caused by over grouting, reducing construction cost and accelerating construction progress.
