A construction method of a hume pipe under the ground is provided to shorten working hours and to cut down on construction expenses by spreading support blocks on the bottom of an excavation section and installing a hume pipe on the support blocks simply without waste of time and manpower, to prevent a leakage of water on a joint by marking gradient values of the bottom of an excavation section on wood posts, connecting thread according to the gradient values and installing a hume pipe in a straight line, inserting a non-woven fabric roll to a hume pipe joint and filling mortar, thereby sealing hermetically, and to apply to the installation of a circular pipe and a double wall pipe. A construction method of a hume pipe under the ground comprises the steps of: erecting wood posts on the starting point and the end point of an excavation section on which a hume pipe is installed; marking gradient values on the wood posts erected on the starting point and the end point; connecting thread to the two wood posts according to the gradient values of the starting point and the end point; arranging and installing the top of support blocks(11) in a straight line to fit to the height of the thread; inserting partition plates(20,20') to partition plate insertions of the support blocks, and putting a hume pipe(30) on a hume pipe support and connecting in a line; pulling out the wood posts and inserting a strap-shaped non-woven fabric roll(60) to a gap of a joint(31) connected with the hume pipe, and placing mortar; and placing reinforced concrete and re-filling up the excavation section with soil. |
