Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] Please refer to Figure 1 to Figure 7 , the reinforced concrete comb anchor 1 of the present invention includes a reinforced concrete entity 2, four lifting seats 3 are arranged on the upper top surface of the reinforced concrete entity 2, and the four lifting seats 3 are distributed on the four corners of the top surface, so as to ensure that the steel bars can be stably lifted Concrete comb anchor1. A drainage hole 4 is also arranged on the top surface, which reduces the difficulty of lowering and recovering the reinforced concrete comb anchor 1 . At the same time, the bottom surface of the reinforced concrete entity 2 is also provided with a groove with a trapezoidal cross-section, which is connected to the drain hole 4, further reducing the difficulty of lowering and recovering the comb anchor. The reinforced concrete body 2 is also provided with...

Abstract

A reinforced concrete comb anchor, which is used for the positioning of cofferdams on river beds, the reinforced concrete comb anchor includes: a reinforced concrete entity; at least one anchor seat, the anchor seat is fixed on the reinforced concrete entity; at least A tooth block, the tooth block is fixed on the reinforced concrete body, and the tooth block is provided with protruding teeth facing the river bed, which can precisely position the cofferdam under the condition of no covering layer, has low construction difficulty, and can be reused.

Description

【Technical field】 [0001] The invention relates to a reinforced concrete comb anchor. 【Background technique】 [0002] In traditional foundation construction, iron anchors are generally used for cofferdam positioning. However, under the condition of no overburden, the traditional iron anchor positioning method cannot be used. At this time, the cofferdam is positioned by punching piles, or by ordinary concrete anchorage. However, the positioning procedure of punching piles is complex, the construction is difficult, and the cost is high; the use of ordinary concrete anchoring positions cannot control the anchor distance during the positioning process, and cannot play the role of precise positioning. 【Content of invention】 [0003] Aiming at the defects existing in the prior art, the object of the present invention is to provide a reinforced concrete comb anchor, which can accurately locate the cofferdam under the condition of no covering layer, has low construction difficult...
