Description

[Detailed Description of the Invention] The present invention relates to an apparatus for treating discharged earth and sand using a hollow excavation method using a spiral auger.

Conventionally, in the spiral auger medium excavation method, which has been implemented as a noise-free and vibration-free construction method for prefabricated piles, the soil excavated continuously by the spiral auger is disposed of by a method in which the piles are finally struck with a Monken. Since a treatment hopper is not used and the discharged soil is left to flow, there is a problem of pollution to third parties such as falling and scattering of the excavated soil, making it impossible to carry out construction in urban areas. In addition, as a method of using a disposal hopper, for example, the one of Utility Model Publication No. 54-27766 is a very large device (approximately 8 tons including the press-in device) in order to have the function of press-fitting piles in the treatment hopper. The disadvantage is that it is heavy and the production cost is high.

The present invention aims to solve the above-mentioned drawbacks of the conventional method, and a soil disposal hopper that is removably hooked to the Monken is installed to receive the discharged soil pushed up by the spiral auger inside the Monken. It produces the following effects.

(1) Pollution caused by falling and scattering of excavated soil will be prevented.

(2) Easy to put on and take off, so you can hit directly with Monken.

(3) Light weight and low manufacturing and transportation costs.

(4) The discharged earth and sand can be disposed of anywhere on the premises.

(5) Being lightweight and compact, assembly and disassembly work is easy.

An example of implementing the present invention will be described below with reference to the drawings. Figures 1A and B show the soil removal treatment hopper installed, with 1 being a pile, 2 being a spiral auger, 3 being a pile cap fixed to the top of the pile 1, and 4 being a pile. A pile head fixed on the pile head fixing cap 3, 5 a soil removal treatment hopper latched onto the pile head 4, and 6 a casing bolted onto the pile head fixing cap 3.

2A, B, and C are a partially cutaway plan view, a longitudinal sectional side view, and a front view showing the main parts of the device of the present invention in a slightly enlarged manner;
is made of a steel plate in a rectangular box shape, has an entrance 5b at the top, and has two arms 7 at the top end. Each of the protruding ends of the arms 7 is provided with a vertical guide piece 7a. The guide piece 7a engages with a guide groove 4a provided on the upper part of the inner and outer surfaces of the monitor 4, and has the function of reliably supporting the earth removal processing hopper 5 when it is placed on the monitor 4 as shown in the figure. Note that the guide groove 4a can also be provided only on the inner or outer surface of the monitor 4.

Next, to explain the operation of the device of the present invention, in the state shown in FIG. The discharged earth and sand is carried into the main body 5a from the casing 6, which has the same inner diameter and has an open end at the same position as the entrance 5b of the discharged earth processing hopper, and is stored in the main body 5a. The earth removal hopper is tilted by locking a wire of a crane (not shown) to the locking hook 8 to lift and move the earth removal hopper, and further locking the wire to the wire locking hook 9 and hoisting it up. ,
It can be dumped at a designated location or onto a dump truck through the loading port 5b or the upper opening. After the earth removal work is completed, the earth removal processing hopper can be removed and the piles can be struck directly with a Monken.
