Abstract

Un método de consolidación de lechada para un pilote prefabricado con guía de revestimiento de pozos completo, que comprende los siguientes pasos: S1, conducir una plataforma de perforación que lleva un revestimiento (1) para realizar la construcción del pozo, realizándose la construcción del pozo a una profundidad de pozo preestablecida para formar un pozo (2); S2. estando alojada la carcasa (1) en el pozo (2); S3. implantar un pilote prefabricado (4) en el pozo (2) de manera que el pilote prefabricado (4) alcance el fondo del orificio del pozo (2); S4. inyectar una lechada (3) en el pozo (2); S5. extraer la carcasa (1) para que el pilote prefabricado (4) y una cavidad interior del pozo (2) se fijen y cementan en una estructura integrada. También se proporciona un pilote prefabricado, que comprende un cuerpo de pilote y un canal de lechada (5) provisto en el cuerpo del pilote, en donde un extremo de entrada de líquido (11) del canal de lechada (5) se extiende desde una superficie del extremo superior del pilote. El cuerpo y un extremo de salida de líquido (12) del canal de lechada (5) se extienden desde una superficie de extremo inferior del cuerpo de pilote y/o una superficie lateral del cuerpo de pilote.A grout consolidation method for a precast pile with a complete well casing guide, comprising the following steps: S1, drive a drilling rig bearing casing (1) to perform well construction, well construction being performed at a preset well depth to form a well (2); S2. the casing (1) being housed in the well (2); S3. implanting a precast pile (4) in the well (2) so that the precast pile (4) reaches the bottom of the hole of the well (2); S4. inject a slurry (3) into the well (2); S5. remove the casing (1) so that the precast pile (4) and an internal cavity of the well (2) are fixed and cemented in an integrated structure. A precast pile is also provided, comprising a pile body and a slurry channel (5) provided in the pile body, wherein a liquid inlet end (11) of the slurry channel (5) extends from a surface of the upper end of the pile. The body and a liquid outlet end (12) of the slurry channel (5) extend from a lower end surface of the pile body and / or a lateral surface of the pile body.
