Description

Large diameter basic engineering surging device

The present invention is to excavate large-diameter pile holes in the basement, insert H-beams into the large-diameter, and then remove groundwater and slime in piles to install concrete mortar. It relates to a surging device.

In general, in the construction of foundations, such as buildings, underground drilling equipment is used to excavate piles in the basement and then install piles in the piles. Depending on the design of the foundation, concrete PHC piles or steel H beams are used.

The pile hole for installing the H-shaped beam is mainly installed in a large diameter pile hole, and when the large diameter pile hole is excavated, the pile hole is inserted while inserting a cylindrical casing rod so that the excavated strata are not collapsed. Even though excavation of the groundwater flows from the underground vein into the casing rod, and the slime (SLIME) generated during the excavation remains, so the groundwater and the slime must be removed before the H-beam is installed. It is possible to maintain the installation strength.

Therefore, the H-beam should be installed in the large diameter pile hole excavated with the casing rod inserted, and the groundwater and slime in the pile hole should be removed. The prior art has several connection rods as shown in FIGS. 11 and 12. 100) Insert both ends of the band coupling (200) or threaded coupling (300) screwed through the space of the H-beam inserted into the pile hole and the upper end of the pump car (PUMP CAR) Groundwater and slime were pumped by connecting to a connection hose.

However, in the case of the prior art band coupling 200, it is inconvenient to use because it has a structure in which a pair of coupling ends 201 of a semicircular shape are protruded and screwed with a bolt and a nut. The ring 200 is enlarged by the protruding both ends 201 so that both ends 201 of the band coupling 200 are caught when the connecting rod 100 is introduced into the space formed in the H-shaped beam. As a result of the phenomenon, it is not easy to insert the connection rod 100, and both ends 201 protruding during the input are damaged by the contact impact with the H-beam, and also have a conventional screw coupling ( In the case of 300, since the connecting rod 100 itself must be rotated to assemble the male screw 101 formed at one end of the connecting rod 100, there is a problem in that it takes a lot of power for the connection work and inconveniences in use. , And also the connection load ( 100) and screw coupling in the process of assembling and disassembling the screw 300, there was a problem that the screw is damaged and can not be used.

In addition, the prior art as described above has a problem in that the groundwater and the slime can not be efficiently removed because it is configured to simply pump the groundwater and the slime using the connecting rod put into the pile hole. If the pump is pumped while the end of the connecting rod is immersed in the groundwater, when the groundwater is large, it is pumped with slime mixed with the groundwater. However, it is pointed out that when the concrete mortar is poured while the slime remains on the bottom of the pile hole, the installation strength of the pile may be weakened.

The present invention has been made in view of the above-mentioned problems in the prior art, and the coupling connecting the connecting rod for pumping the groundwater and the slime in the pile hole is combined with a simple means of inserting or relaxing a strand of wire cable. And a coupling structure for dismantling, and also a surging pump that enables pumping groundwater and slime by injecting high pressure air upward from the lower end of the connecting rod connected to the lower end. Another purpose is to provide a structure, and another purpose is to provide a surging spraying structure that mixes the slime deposited on the bottom of the pile hole with the ground water by spraying high pressure air from the upper side of the connecting rod. Concrete mortar by connecting the supply rod for concrete mortar to the top of the connecting rod Helping you to easily perform the work placement will put another one designed for different purposes.
