Description
Technical field
The invention belongs to municipal works technical field, is related to a kind of integral type inspection shaft and its installation method.
Background technology
During at present municipal pipeline is built, traditional brick inspection shaft and armored concrete inspection shaft still plays important work
With, but traditional inspection shaft has exposed congenital defect, its mainly have it is following some：
First, traditional brick well uses the construction process of solid brick plus mixed mud, and transport difficult, installation period is long, no
Easy care, and if to have caved in also have certain human safety issues to related operating personnel.Construction progress can not be flexibly controlled,
Such as weather problems cause scene to construct, and go wrong and are difficult to improve.
2nd, armored concrete inspection shaft itself is heavy, the handling instrument of specialty is needed, so as to increased operating expenses.Steel
Though reinforced concrete inspection shaft has certain acid resistance, acid resistance is well below plastic inspection well.
3rd, armored concrete inspection shaft mostly is building block youngster composition or pre-formed, and the steel reinforced concrete well gap of building block composition is more, close
Envelope effect is difficult to ensure that.And connected mode is gun iron link, effluent seepage easily occurs, permeate, it is easily secondary to Groundwater formation
Pollution, affects the living environment of resident.
4th, armored concrete inspection shaft causes internal resistance larger due to itself rigid and xoncrete structure, needs one
Fixed staff goes into the well and draw clearly.
5th, armored concrete inspection shaft cannot be constructed well by high temperature, severe cold and wet rainy day gas.And can not return
Receive, pollute environment, waste of resource.
6th, traditional brick well uses solid brick as construction raw material, does not meet the requirement of the sustainable development national conditions of China,
Minstry of Housing and Urban-Rural Development of People Republic of China's (218) number file in 2004 has been run counter to, the regulation of clay solid brick has clearly been prohibitted the use of.
There is prefabricated plastic inspection well before more than 10 years in China, was avoided that above-mentioned most of problem, and in cities and towns life
In community living, the application succeeded, but due to the prefabricated inspection shaft bore of living community it is little, low intensity, with town road
On inspection shaft require there be certain distance, in municipal, application is almost blank.
