A prefabricated large block assembled concrete drainage pipe base and its construction method

Abstract

The invention belongs to a large block assembled type prefabricated concrete drainage pipeline base and a construction method thereof. The method includes the steps of prefabricating the concrete drainage pipeline base, carrying out base center line paying-off on the bottom of a constructed pipeline trench, building the concrete drainage pipeline base in a spliced mode, placing pipelines downwards and installing the pipelines, pouring pipe protection concrete into the assembled concrete drainage pipeline base with flanges serving as formworks on the two sides, and the like. The prefabricated concrete drainage pipeline base comprises a board body and a lifting hook. An outer convex edge protruding out of the front end face of the board body is arranged on the lower portion of the front end of the board body. An inner concave edge sinking into the rear end face of the board body is formed in the lower portion of the rear end of the board body. Steel bar lantern rings for clamping steel bars are arranged on the inner edges of the flanges on the two sides of the board body at intervals. The large block assembled type prefabricated concrete drainage pipeline base and the construction method thereof have the advantages that the method and the structure are novel and simple, the trench bottom construction procedures are reduced, working efficiency is high, construction cost is low, safety is high, construction speed is high, disturbance on undisturbed soil and the environment is small, energy saving and environment friendliness are achieved, and the linked pipe protection effect is good.

Description

technical field [0001] The invention relates to a prefabricated large block assembled concrete drainage pipe base and a construction method thereof. Background technique [0002] At present, the bases of domestic municipal pipe network concrete drainage pipes and various underground pipes are basically constructed with cast-in-place concrete bases. , formwork, pouring concrete base, downpipe, safety pipe, pouring concrete for protective pipe, backfilling, compaction. Obviously, the traditional construction method has many working procedures at the bottom of the trench and takes a long time, which will not only affect the traffic, but also cause great disturbance to the undisturbed soil at the bottom of the trench. At the same time, the trench is exposed for a long time, and the bottom of the trench is easily disturbed by the surrounding environment. In the northern region, the temperature is low, and the bottom of the trench is easy to be frozen; very high. If the undistu...

Obviously, the traditional construction method has many working procedures at the bottom of the trench and takes a long time, which will not only affect the traffic, but also cause a large disturbance to the undisturbed soil at the bottom of the trench

At the same time, the trench is exposed for a long time, and the bottom of the trench is easily disturbed by the surrounding environment. In the northern region, the temperature is low, and the bottom of the trench is easy to be frozen; very high

If the undisturbed soil at the bottom of the tank is disturbed, frozen or soaked in water, the bearing capacity of the foundation will be reduced. The decline in the bearing capacity of the foundation will cause uneven settlement of underground pipelines, water leakage, air leakage and road surface settlement, endangering social traffic and personal safety.
