The wall thickness of described steel cylinder is more than or equal to 8mm, can meet the requirement that pipeline bears indoor design pressure.
The socket steel ring of described front tube and rear end pipe is provided with the corresponding pressure testing water injection hole leading directly in front tube and rear end pipe tube chamber respectively.
The sealing steel ring of described rear end pipe is provided with grease hand-hole and the injected hole in straight-through rear end pipe tube chamber.
Prestressed concrete cylinder pipe for jacking construction method (PCCPJ) relay well pipe is comprised of front tube and rear end pipe two-part, comprises socket steel ring, tube wall concrete, Framework Of Steel Reinforcement, steel cylinder, bellmouth steel loop, outer steel pipe, sealing steel ring.And can utilize original push pipe mould to build moulding.The bellmouth of this relay pipe, socket size are identical with Standard PC CPJ tube coupling, and front tube is identical with the accurate PCCPJ tube coupling of a feast-brand mark with rear end pipe combination effective length.This relay well pipe redesigns in original PCCPJ push pipe pipeline configuration size, and steel cylinder steel plate thickness is more than or equal to 8mm, to meet pipeline, bears internal pressure; Tube wall concrete arranges Framework Of Steel Reinforcement, to meet pipeline, bears external loads and the axially requirement of top power; Solder mask steel pipe outside the bellmouth of front tube, concrete embedded sealing steel ring outside rear end pipe socket end, outer steel pipe and sealing steel ring are slidably matched and can guarantee pipe jacking construction stroke and encapsulation thereof.
Using method: according to working design, lay first relay well pipe when push pipe gross thrust reaches design thrust value, lay a relay well pipe later while often reaching design thrust value, and enable relay well pipe when main jacking force reaches design thrust value.When relay well pipe is started working, first relay well pipe jacking, unloads oil pressure, then second relay well pipe jacking, unloads oil pressure, successively sequential operation, after all relay well pipes are all finished the work, start working pit jack, start first relay well pipe simultaneously, by this step cycle jacking.After jacking completes, remove successively from front to back the jacking device in relay well pipe, the closed docking of front tube and rear end pipe, and carry out joint socket sealing pressure testing check according to standard tube coupling, water injection hole, injected hole, the grease holes of after acceptance(check), tackling relay well pipe carry out shutoff.
The beneficial effects of the utility model are, provide a kind of for PCCPJ relay well pipe, PCCP can be met and do not slot continuously length apart from jacking construction requirement, meet Standard PC CP and bear external and internal pressure, two rubber gasket seal request, overcome and adopted the drawback of wearing again this traditional arrangement and method for construction of pressure tube in RCP sleeve pipe, reduced pipe engineering expense.
