Description

Connection structure of cylindrical tube of homogeneous or dissimilar materials compatible in excavation construction

The present invention is to insert a cylindrical tube of the same type or heterogeneous material when the ground excavation in civil engineering and construction sites together to facilitate the easy and convenient connection of the cylindrical tube directly on the site according to the excavation depth to facilitate the efficiency and speed of work It relates to a cylindrical tube connection structure of the same or different materials compatible during excavation construction.

In general, in the excavation construction for construction or building foundation construction, first drill the excavation hole by using the excavation equipment in the ground, and then construct the column buried in the ground by filling the concrete with steel pipe or steel frame in the excavation hole.

As such, the excavation equipment is commercially available in different structural equipment according to different specifications according to the purpose or the conditions of the geological (geological), the type can be classified into two types can be described compression.

One of them is a type of direct excavation method in which excavation equipment excavates the strata without using steel pipes when the state of the strata is in good condition or when the excavation is not deep.

The other type of drilling equipment is used for drilling by embedding steel pipe in the drilling hole. The drilling equipment is inserted into the steel pipe so that the bit of the drilling equipment is exposed to the bottom of the steel pipe, and then the bit rotates. A hole wider than the diameter of the steel pipe is drilled, and when the excavation is completed, there is a kind of indirect excavation method which is lifted again through the steel pipe to recover the excavation equipment.

The former direct drilling method is not a problem, but in the latter indirect drilling method, the steel pipes are simultaneously nailed, and it is necessary to connect and connect the steel pipes according to the drilling depth. Because the connection work is difficult, it is difficult to connect, so a welding technician must be required, which leads to safety accidents and waste of labor costs, and to be reused, the welding part or the middle of the steel pipe must be cut. It is difficult and difficult to maintain the straightness when vertically excavated when welded to be reused after cutting, and eventually there was a problem in that it is not possible to bury the steel pipe to the desired excavation depth.

This problem is the same in the steel pipe grouting method which is widely used as part of the tunnel reinforcement method.

In general, the steel pipe grouting method includes the steps of drilling the ground, inserting a steel pipe provided with a strainer (groove injection part) in the drilled hole, inserting a sealing material between the steel pipe and the hole, and installing a packer. While it is made of a step of injecting cement, but recently disclosed in the Republic of Korea Patent Publication No. 100919628, a technology has been developed that can facilitate the installation of steel pipes using the collapsible wing bit.

Nevertheless, as described above, the connection method of the steel pipe is consistent with the welding method and still has the above problems.

In addition, in the micro pile method or other helical pile method, there are still problems associated with the connection of the steel pipe.

The present invention is to solve the above problems,

In order to insert the cylindrical tube of the same or different materials into the excavation hole to be excavated at the time of the ground excavation, the cylindrical tube can be directly and easily connected to the site in accordance with the excavation depth to facilitate the efficiency and speed of work. There is a purpose.

However, these problems are illustrative, and the scope of the present invention is not limited thereby.
