Abstract

Present invention relates to a kind of buried jet chimney leakage inspection method, it is characterized by comprise the steps: step 1 that this section of heat-insulation layer is removed 50mm length by trocar sheath perforate in the middle part of leakage pipeline section, dividing plate is used to be cut off by pipeline from trocar sheath tapping, it is ensured that dividing plate and left and right pipeline 2 seal；Step 2, after certain time (8 10 hours), by dividing plate both sides SEA LEVEL VARIATION, can determine whether out that leak source must be in the higher side of water level；Step 3, takes a little at water level upper side interlude, repeats above-mentioned partition mode, until finding leak source.

Description

A kind of buried jet chimney leakage inspection method
Technical field
Present invention relates to a kind of buried jet chimney leakage inspection method.
Background technology
Along with the quickening of Development of Urbanization, promoting the image in city further, lower berth, ground all taked by increasing pipeline If mode, as the jet chimney of High Temperature High Pressure, underground piping can leak unavoidably, once leaks, the work of excavation leakage detection Amount is relatively big, and once core pipe leakage rate hour, adds difficulty to leakage detection especially.
Owing to buried jet chimney has about 100mm heat-insulation layer, when pipeline minor leakage, may only have a small amount of steam Emerging, more to condense water form spilling, leakage detection is the most difficult.And buried pipe is fixed and is held the distance arriving sliding end longer, Cause the biggest trouble to accurately lookup leakage position.
Therefore, when promoting buried jet chimney minor leakage, leakage detection efficiency is the most necessary.
Summary of the invention
In view of this, in order to solve the problems referred to above, the present invention provides a kind of buried jet chimney leakage inspection method.
A kind of buried jet chimney leakage inspection method, comprises the steps:
Step 1, trocar sheath perforate in the middle part of leakage pipeline section, this section of heat-insulation layer is removed 50mm length, uses dividing plate from trocar sheath Pipeline is cut off by tapping, it is ensured that dividing plate and left and right pipeline 2 seal；
Step 2, after certain time (8-10 hour), by dividing plate both sides SEA LEVEL VARIATION, can determine whether out that leak source must be higher at water level Side；
Step 3, takes a little at water level upper side interlude, repeats above-mentioned partition mode, until finding leak source.
After using above method, can the most effectively investigate buried jet chimney minor leakage.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention 1.
Detailed description of the invention
Embodiment 1:
With reference to Fig. 1, a kind of buried jet chimney leakage inspection method, comprise the steps:
Step 1, trocar sheath 1 perforate in the middle part of leakage pipeline section, this section of heat-insulation layer 3 is removed 50mm length, uses dividing plate 4 from overcoat Pipeline 2 is cut off by pipe 1 tapping, it is ensured that dividing plate 4 and left and right pipeline 2 seal；
Step 2, after certain time (8-10 hour), by dividing plate 4 both sides SEA LEVEL VARIATION, can determine whether out that leak source must be higher at water level Side；
Step 3, takes a little at water level upper side interlude, repeats above-mentioned partition mode, until finding leak source.
After using above method, can the most effectively investigate out buried jet chimney minor leakage point.
