Built-in anti-floating anchor blocking structure used in foundation mat for deep-well dewatering well and construction method
The invention relates to a built-in anti-floating anchor blocking structure used in a foundation mat for a deep-well dewatering well. A steel sleeve is arranged on a rainfall wellhead. The bottom of a rainfall well forms a body expansion soil end through expansion holes. A bag type anti-floating anchor rod is arranged in the well. An expansion end plate is arranged in an anchor rod bag. Annular positioning rebars are arranged on the bag type anti-floating anchor rod. The anchor rod bag forms a grouting body expansion anti-floating end through high-pressure pouring after being inserted into the body expansion soil. The upper end of the anchor rod is anchored after penetrating a blocking steel plate. Connection rebars are connected to the top face of the blocking steel plate in a welding manner. The bottom face of the blocking steel plate is provided with a waterproof rubber gasket. The blocking steel plate is connected with a steel sleeve connection steel plate through bolts. The top face of the blocking steel plate sequentially comprises a waterproof concrete layer and a post-poured concrete sealing body. According to the deep-well dewatering well built-in anti-floating anchor blocking structure, by means of the built-in anti-floating anchor rod manner, the wellhead blocking quality can be guaranteed while the situation that the rainwater wellhead is destroyed due to the fact that underground water comes up to the top during the later period is reduced, and the built-in anti-floating anchor blocking structure has better economic and technical benefits.
