Description
Technical field
The present invention relates to the leak detection wells and leak detection report in the plumbing technical field of building more particularly to a kind of leak detection pipe trench
Alarm device.
Background technique
Water supply and sewerage pipeline leakage or rupture will cause building basis and impregnated and depression, to influence building safety.
By water supply and sewerage pipeline setting in pipe trench of hunting leak, and the setting leak detection well along leak detection pipe trench, in order to to leak detection tube
Water supply and sewerage pipeline in ditch is checked.
Water supply and sewerage pipeline leakage damage building basis in order to prevent, water supply and sewerage pipeline is laid in and is hunted leak in pipe trench
Portion, common leak detection pipe trench are current, half current, non-passage, and for current or half current leak detection pipe trench, service personnel can
Inspection and maintenance is carried out to drainage pipeline to enter in leak detection pipe trench by well of hunting leak.For the leak detection pipe trench of non-passage, people is overhauled
Member directly observes in the collecting-tank in leak detection pipe trench whether have ponding by well of hunting leak, to judge supplying drainage in leak detection pipe trench
Whether road leaks or ruptures.The leak detection pipe trench of either current or non-passage, passes through only by service personnel is irregular
Leak detection well overhauls the intake-discharge pipe in leak detection pipe trench, has following drawback, on the one hand, cannot find supplying drainage in time
Water leakage situation occurs for road, causes the waste of water resource；On the other hand, by leak detection well to leak detection pipe trench in water supply and sewerage pipeline into
It is time-consuming and laborious when row maintenance, it is low efficiency, at high cost.
At the same time, the leak detection well of traditional water supply and sewerage pipeline has brick leak detection well and armored concrete leak detection well.It is brick
Well hunt leak using sintering solid brick and masonry of cement mortar, armored concrete hunts leak well using concrete masonry units.Tradition leak detection well
In practical applications, speed of application is slow, and comprehensive cost is high；The smaller leakage of leak detection pipe trench interior conduit is not easy to be found；Construction leak detection
The raw material of well not can be recycled, and be easy to cause environmental pollution and the wasting of resources.
In view of this, it is necessary to the leakage detection apparatus of leak detection pipe trench in the prior art be improved, to solve above-mentioned ask
Topic.
Summary of the invention
The purpose of the present invention is to provide water supply and sewerage pipelines in a kind of automatic detection leak detection pipe trench, and leak, in time whether occurs
