Description
Technical field
The present invention relates to underground pipe gallery technical field of construction, more specifically, are related to one kind and pass through buried concrete water pipe
The construction method of the underground pipe gallery in road.
Background technique
Underground pipe gallery is especially constructed in old town, and various barriers are inevitably encountered, especially, the underground being laid in advance
When piping lane encounters buried concrete waterpipe, conventional method is that concrete water pipeline is relocated, i.e., first arranges another time time coagulation
Native waterpipe, to avoid the engineering excavation range of underground pipe gallery, another time concrete water pipeline and original buried concrete water
After pipeline is connected, then organize to excavate.Because underground pipe gallery be linear engineering, such as relocate, concrete water pipeline need to detour it is up to a hundred even
Upper km, not only project amount is big, costly, and the duration will also be affected, and detour pipeline also will affect sewage smooth discharge.
In addition, concrete water pipeline can not be truncated, no when the underground pipe gallery being laid in advance crosses buried concrete waterpipe
It then will be unable to drain, the underground pipe gallery being laid in advance also changes its course without place, then cannot achieve the laying of underground pipe gallery.
Summary of the invention
In view of the above problems, the object of the present invention is to provide a kind of ground for passing through buried concrete waterpipe without detouring
The construction method of lower piping lane.
To achieve the goals above, the present invention provides a kind of construction party of underground pipe gallery for passing through buried concrete waterpipe

Pond and the second conversion pond are changed, steel pipe is set between two conversion ponds, the both ends of the steel pipe are respectively protruding into first turn
Change pond and the second conversion pond；Water outlet is opened up on the concrete water pipeline in the first conversion pond, converts water second
Open up water inlet on concrete water pipeline in pond, the surface area of the water outlet and water inlet is all larger than the concrete water pipe
The orifice area in road, the concrete water pipeline section for offering water outlet is first segment concrete water pipeline, offers water inlet
Concrete water pipeline section is second segment concrete water pipeline, and water flows out to first turn from the water outlet of first segment concrete water pipeline
Pond is changed, into steel pipe, the second conversion pond is flowed by steel pipe, second segment concrete water pipe is then flowed by water inlet
Road；Concrete water pipeline, the concrete water pipeline section of the truncation is truncated between the first conversion pond and the second conversion pond
For third section concrete waterpipe, the cutout of first segment concrete water pipeline and second segment concrete water pipeline is sealed
It is stifled, wherein the length of the third section concrete waterpipe is less than the distance between the first conversion pond and the second conversion pond；
Carry out piping lane construction；After piping lane construction, it is backfilled to set distance below concrete water pipe, it will be with a thickness of the mixed of the set distance
Concrete board band is arranged between two conversion ponds, restores concrete water pipeline, wherein the side for restoring concrete water pipeline
Method includes: with concrete slab band for support, using concrete by third section concrete waterpipe and first segment concrete water pipeline
Spliced with second segment concrete water pipeline, removes the truncation of first segment concrete water pipeline and second segment concrete water pipeline
The closure of mouth blocks water outlet and water inlet using concrete, removes the first conversion pond and the second conversion pond, is backfilled to road
Base, road surface of constructing.
The construction method of the underground pipe gallery of the present invention for passing through buried concrete waterpipe first will be in concrete water pipeline
One section be replaced as the steel pipe that can be reinforced, piping lane reverts to concrete water pipeline after the completion of excavating again, mixes after ensure that construction
The anti-corrosion dredging of solidifying soil waterpipe, without detouring, construction volume is small, and expense is low, does not influence the construction period of piping lane.

Step 3, water is converted in the first segment concrete Main Underground sewage pipe upper half in the first conversion pond and second
Multiple 30-50mm thickness 150 × 150mm grid is cut in the second segment concrete Main Underground sewage pipe upper half in pond respectively, then uses wind
Pick is crushed the grid, is respectively formed water outlet and water inlet not less than concrete Main Underground sewage pipe orifice area, allows water
It crosses from concrete Main Underground sewage pipe to steel pipe；
Step 4, concrete Main Underground sewage pipe, the flirtatious lower main blowdown of the concrete cut down are truncated between two conversion ponds
Pipe is the main sewage pipe of third section concrete, to the cutout of the main sewage pipe of the first section concrete and the main sewage pipe of the second section concrete
Carry out concrete plug；
Step 5, after the completion of piping lane excavates, piping lane construction is carried out, is backfilled to the main blowdown of concrete with 2:8 dirt after having constructed
200mm pours 200mm thickness C30 concrete slab band as pipe basis under tube bottom, is restored, comprising: first by third section concrete
Main sewage pipe successively connects, the main sewage pipe two sides of third section concrete and the main sewage pipe of the first section concrete and the second section concrete
Main sewage pipe lower part, which is emptied, makees U-lag cast-in-place concrete, fills in U-lag when concrete strength reaches C20 in joint part dabbing
Enter water and carry out examination water experiment, after ne-leakage, concrete in the main sewage pipe of the first section concrete and the main sewage pipe of the second section concrete is sealed
It is stifled to be cleaned out with pneumatic pick, the formwork in the first conversion pond and the second conversion pond, with concrete by water outlet and water inlet
Closely knit, to convert pond and the second conversion pond for first after ne-leakage top dismounting is blocked, dismounting steel pipe backfill is normal to do road
Base, road surface of constructing.
In the above-described embodiments, using the main sewage pipe of concrete of steel pipe replacement truncation, influence sewage discharge is avoided, is led to
The arc connection for crossing truncated position, expands the functions such as dredging in pipe, anti-corrosion, so that the discharge of sewage is more smooth.
The present invention is illustrated the construction methods for the underground pipe gallery for passing through buried concrete waterpipe by multiple implementations, but
It is that the present invention is not limited thereto, the pipeline passed through above the various subterranean buildings in city is reinforced can be applied using of the invention
Work method.
Although content disclosed above shows exemplary embodiment of the present invention, it should be noted that without departing substantially from power
Under the premise of benefit requires the scope of the present invention limited, it may be many modifications and modify.In addition, although element of the invention
It can describe or require in the form of individual, it is also contemplated that it is multiple, it is unless explicitly limited odd number.
