Title:
HYDRAULIC TEST DEVICE
Document Type and Number:
Japanese Patent JP2015140528
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problems of being unable to stabilize a pouring-pumping water quantity since a pump head lacks only by a storage pump installed in a boring hole having an inner diameter of 51 mm, of being unable to arrange a non-pulsation quantitative pump in the boring hole having the inner diameter of 51 mm, and of being unable to pump underground water in the hole by 10 mm or more since the pump head is small in the non-pulsation quantitative pump.SOLUTION: The underground water in a test section 44 is pumped substantially up to the ground by a storage pump 48, and the underground water pumped by its storage pump 48 is transferred by the non-pulsation quantitative pump 22 installed on the ground, and the underground water is pumped up to the ground from the test section 44 of the boring hole 42 having the depth of 10-100 m by using a small-scale storage pump 48 insertable into the boring hole 42 of the inner diameter of about 51 mm, and the underground water pumped by its storage pump can be continuously transferred by a fixed quantity by using the non-pulsation quantitative pump 22 of a large dimension installed on the ground.
