Abstract

The invention discloses a tightness test method for a cutter suction dredger. The method adopts three modes including air pressing, water pressing and water flushing; a weld in a test position keeps clean without welding slag, oil stain and corrosion; the weld in the test position is not coated with a paint, cement or asphalt before test; the tightness test method is performed in an interval or cross manner, and adjacent cabins are not performed simultaneously; and the hull bottom of the located cabin is subjected to blocking strengthening or strengthening with a rigid support before a water pressing test. The tightness test method for the cutter suction dredger is convenient to operate and good in working effect.

Description

The tightness test method of cutter suction dredger

Technical field

The present invention relates to a kind of tightness test method of cutter suction dredger.

Background technology

The tightness test method of existing cutter suction dredger, complex process, working effect is undesirable.

Summary of the invention

The object of the present invention is to provide a kind of tightness test method of cutter suction dredger of good working effect.

Technical solution of the present invention is:

A tightness test method for cutter suction dredger, is characterized in that: adopt calm the anger, setting-out, three kinds of modes of bath; Test position weld seam keeps clean, without welding slag, greasy dirt and corrosion; Test position weld seam not coating paint, cement or pitch before test; Tightness test adopts interval or cross method to carry out, and when adjacent cabin is different, carries out; Before packer permeability test, the hull bottom in cabin, place carried out to the reinforcement of cloth pier or support and strengthen by rigidity.

Rigidity support is reinforcing bar material.

Rigidity support is wood materials.

The present invention is easy to operate, good working effect.

Below in conjunction with embodiment, the invention will be further described.
