Title:
MUCK CAR ON WHICH A TUBE GASKET USING PNEUMATIC PRESSURE IS INSTALLED
Document Type and Number:
WIPO Patent Application WO/2011/149192
Kind Code:
A2
Abstract:
The present invention relates to a muck car on which a tube gasket using pneumatic pressure is installed, and particularly, to an excavated-soil transport muck car used to transport soil excavated at an excavation site to an excavated-soil storage pit, wherein the excavated-soil transport muck car has a pneumatically expanding and contracting tube gasket (20) installed at an edge thereof between a sidewall (11) of the excavated-soil transport muck car (10) and a ground surface (12) so as to prevent the leakage of contaminated water through a gap between the sidewall (11) of the excavated soil transport muck car (10) and the ground surface (12). According to the present invention, after excavated soil is loaded onto the excavated-soil transport muck car at an excavation site, contaminated water contained in the excavated soil is prevented from leaking through a gap between a bottom sidewall of the excavated-soil transport muck car and the top of the ground surface, during transport along rails over which the muck car travels, in order to significantly reduce impediments in the work environment and wasted manpower.
