Embodiment 1

[0043] Please refer to Figure 1-11 , a prefabricated tubular pile static pressure construction device integrating positioning and sealing piles in this embodiment, such as figure 1 As shown, it includes a pressure distribution body 1 and a pressure-bearing fixed base 2 that are arranged to match each other up and down;

[0044] like figure 2 , Figure 10 and Figure 11As shown, the pressure distribution body 1 includes an annular pressure distribution block 3, the middle part of the pressure distribution block 3 is provided with a pipe pile through hole 31, and the inner side of the pipe pile through hole 31 is symmetrically provided with a first arc-shaped groove. 32. The second arc-shaped groove 33, one end of the first arc-shaped groove 33 is hinged with an arc-shaped downward pressure beam 34, and the horizontal side of the arc-shaped downward pressure beam 34 is provided with a pressure device groove 35, the One end of the slot 35 of the pressurizing device is hinge...

Embodiment 2

[0056] This embodiment provides a method for construction using the prefabricated pipe pile static pressure construction device as described in Embodiment 1, including the following steps:

[0057] Step 1: Drill the pre-buried hole at the predetermined piling position, install the prefabricated pipe pile static pressure construction device on the static press, pressurize the pre-buried hole vertically, until the disc-shaped pressure-bearing platform 21 is parallel to the ground, and A total station is used to ensure that the prefabricated pipe pile static pressure construction device is installed vertically;

[0058] Step 2: Lift the prefabricated pipe pile, align it with the set pipe pile through hole 31, and pass through the feeding through hole 23 and the positioning pipe 25 in sequence, and at the same time move the static pressure pile machine until the pressurized pile head is facing the prefabricated pipe pile Top, connecting the prefabricated pipe pile and the pressuri...

Abstract

The invention relates to the technical field of prefabricated pipe piles, and discloses a static pressure construction device and method for prefabricated pipe piles integrating positioning and sealing piles. The ring-shaped pressure distribution block, the pressure-bearing fixed base includes a disc-shaped pressure-bearing platform and a pipe-shaped discharge bin fixedly connected up and down, and a plurality of positioning pins are fixedly connected to the bottom surface of the discharge bin. Through the mutual cooperation of the pressure distribution body and the pressure-bearing fixed base, the present invention can not only effectively ensure the initial alignment and correction of the pile sinking, but also effectively reduce the influence of the pile body deviating from the pile position caused by the floating of the pile body during the pile sealing process, and further enhance the stability of the pile. The overall bearing capacity of the foundation improves the turnover rate of pile foundation construction equipment and has high practical value.

Description

technical field [0001] The invention relates to the technical field of prefabricated pipe piles, in particular to a static pressure construction device and method for prefabricated pipe piles integrating positioning and sealing piles. Background technique [0002] At present, concrete prefabricated pipe piles are mainly used as building foundation piles, and mainly bear vertical loads. The more commonly used methods are hammering and static pressure pile method. The construction of static pressure pile method is to press the pile into the soil through the pile pressure mechanism of the static pile driver with the counterweight of the pile driver and the counterweight on the frame to provide the reaction force. The advanced pile sinking process, this pile pressing method completely avoids the vibration, noise and pollution generated by hammering pile driving, so it has the advantages of no noise, no vibration, no impact force, no pollution, etc. during construction, and the p...
