Precast pile for post-grouting of pile end
The invention discloses a precast pile for pile end post-grouting. The precast pile is provided with a grouting inlet and a grouting outlet, and a grouting passage communicated with the grouting inlet and the grouting outlet is arranged in the precast pile. A grouting device (4) is assembled at the grouting outlet; the grouting device comprises a grouting body (41), and the grouting body is provided with an open mounting end and a closed grout outlet end; a sealing ring (42) is arranged on the peripheral surface of the mounting part; a grout outlet hole (47) is formed in the grout outlet part and is communicated with the interior and the exterior of the grouting body; a check valve (45) is arranged on the grout outlet portion of the grouting body in a sleeved mode, a grout outlet hole formed in the grout outlet portion is covered with the check valve, and a rubber sleeve (44) is arranged outside the check valve in a sleeved mode. And the mounting part of the grouting body of the grouting device is assembled at the grouting outlet. And a grouting device is arranged at the grouting outlet, and in the grouting device, the grout outlet part of a grouting body is sleeved with a check valve, so that grout cannot flow back into a grouting channel of the precast pile.
本发明公开了一种用于桩端后注浆的预制桩。该预制桩具有注浆入口和注浆出口，预制桩内部设置有连通注浆入口和注浆出口的注浆通路；在注浆出口处装配有注浆器(4)；注浆器包括注浆本体(41)，注浆本体具有开口的安装端以及封闭的出浆端；安装部的外周面上设置有密封圈(42)；出浆部处开设有出浆孔(47)，该出浆孔连通注浆本体内外；在注浆本体的出浆部处套设有逆止阀(45)，该逆止阀将出浆部处开设的出浆孔覆盖住，在逆止阀的外部套设有橡胶套(44)；注浆器的注浆本体的安装部装配在注浆出口处。在注浆出口处设置注浆器，该注浆器中，在注浆本体的出浆部处套设有逆止阀，浆液无法回流至预制桩的注浆通路中。
