The cirele bend of the top connects, and the both ends of C-type steel pipe are welded on the welded plate of the second standard connector.Second standard connects
The application method of part is identical as the application method of the second standard connector in water suction mine timbering and alcove holder, again without detailed
Thin narration.
In the step 3, concrete layer is poured into a mould in the peripheries anti-bottom Gong Chu of C-type steel pipe, when pouring into a mould concrete layer, C-type steel pipe
Positioned at pump house below ground part will not Transducers Embedded in Concrete layer, in order to increase its assemble intensity, at the anti-bottom arch of C shape steel tubes
Concrete layer is poured into a mould in periphery, can then pour into a mould concrete to realize, C-type steel pipe is located at pump by digging groove at anti-bottom arch
Concrete is not poured into a mould around other pipeline sections of room below ground part, is saved material, is reduced cost.
The support system of the present invention, sectional shelf-unit use concrete filled steel tube, have relative to traditional reinforced concrete structure
There is a higher bearing capacity, when original state, concrete is uncured can be born larger country rock load by steel pipe, avoid biography
Uniting, pump house water-absorbing well reinforced concrete structure initial imperfection is big, and the later stage is easily destroyed, and causes tunnel unstability, pump house system destruction
The initial strength of support system has been effectively ensured in defect, improves the overall stability of support system, reduces the tunnel later stage and returns
Rate is repaiied, the service life of support system is extended, is of great significance for the safety and high efficiency of deep resource.Sectional shelf-unit is adopted
It is simple in structure with fabricated construction, it is easy for construction.
Narration part in detail does not use the state of the art in the present invention, again without describing in detail.
