Description

Medium-large rotary penetration joint structure and manufacturing method thereof { Medium-large rotary penetration joint structure and manufacturing method thereof }

The present invention relates to a medium-to-large rotary penetration joint structure and a method for manufacturing the same, and more particularly, by providing a joint structure consisting of a lower joint and an upper joint to connect rotary pipes penetrating into the ground, and connecting the lower joint and the upper joint to the rotary pipe By fastening each of them, the coupling force and the bearing capacity of the connection part are improved and shock or vibration generated in the process of penetrating the ground is buffered to prevent the connection part from being damaged or bent, and its manufacturing method It is about.

In general, steel pipe piles are constructed to secure the bearing capacity of large structures or bridges built on soft ground, and are also applied to earth retaining work, buoyancy anchor work, building foundation work, slope reinforcement work, etc. That is, the steel pipe pile plays a role in performing support from the earth pressure and structural stability of the ground of the construction building by being pressed into the ground by hitting it to a certain depth.

As a common method of installing such steel pipe piles in the ground, a method of drilling a certain depth in the target ground with a driver using a pile driver (pile driver) and then driving a pile from the upper end to install it in the ground, and a separate pile hole There is a method of directly rotating and inserting a steel pipe pile into the target ground without drilling.

In the case of applying the method of directly rotating and inserting the steel pipe pile as in the latter, the lowermost end of the steel pipe pile has a spiral blade. Therefore, when the steel pipe pile is rotated forward, the steel pipe pile is driven in by the forward movement of the spiral blade.

In addition, if you want to pull out the inserted steel pipe pile, if you reverse the rotation, the steel pipe pile is pulled out by the turning and retreating movement of the spiral blade.

In order to rotate the steel pipe pile having a spiral wing, rotational force must be supplied from the actuator, and the actuator must have a structure connected to the actuator's rotating shaft and a structure in which the rotating shaft and the steel pipe pile are separated after the steel pipe pile is pulled out. In this way, in order to insert, pull out, and separate the spiral steel pipe pile, a joint, which is an intermediate means having a function of connection and separation between the rotary shaft of the actuator and the spiral steel pipe pile, is required.

However, since the joint connecting the conventional steel pipe piles is made of a structure, there is a problem in that the coupling force and bearing capacity between the steel pipe piles is lowered, and the connection between the steel pipe piles is damaged or bent due to external force or vibration generated during the penetration process. will remain
