Description
Technical Field
The utility model relates to the technical field of supporting construction of structures under the current situation of channel excavation protection, in particular to a supporting structure of a signal tower under the current situation of channel excavation protection.
Background
With the continuous progress and development of urban construction, urban water system construction is more and more close to the current situation of important building structures such as houses, pipelines, bridges, signal towers and the like. The channel construction is a measure for connecting a water system and optimizing urban drainage corridors, the channel side slope is a permanent structure, meanwhile, the safety protection of a large number of building structures is involved in the channel water system construction process, and particularly, the signal tower relates to a sensitive building structure for civil safety and is more important to protect. The common channel supporting scheme includes steel sheet pile, prestressed pipe pile, cement-soil mixing pile, cast-in-place pile and other methods. However, the channel of the signal tower section is excavated to form a permanent near-water surface, the signal tower is easy to deform, and the near-water surface is easy to corrode the land, so that a supporting structure for excavating the channel to protect the signal tower in the current situation is urgently needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a supporting structure system for protecting a signal tower, simultaneously has the advantages of economy, reasonability and convenient construction, and provides an effective current building protection technical scheme.
The technical scheme for solving the technical problems is as follows:
the utility model provides a supporting construction of channel excavation protection current situation signal tower, supporting construction is the structure for satisfying channel excavation protection current situation signal tower, its characterized in that: the device comprises a supporting structure arranged around a current signal tower, wherein a reinforced concrete crown beam is arranged at the top of the supporting structure; and one side of the supporting structure, which is close to the signal tower, is provided with a waterproof curtain pile, and the adjacent water side of the supporting structure is provided with a concrete protective surface.
Furthermore, the supporting structure is composed of a plurality of cast-in-situ bored piles vertically fixed on the periphery of the current signal tower; the cast-in-situ bored piles are arranged at equal intervals along the periphery of the current signal tower.
Furthermore, the waterproof curtain pile is a waterproof wall formed by meshing double-pipe high-pressure jet grouting piles.
Further, the concrete facing is cast-in-place 20cmC20 underwater concrete.
The utility model has the beneficial effects that: the utility model adopts a combined supporting system of drilling cast-in-place piles arranged around, high-pressure jet grouting piles and water-facing surface cast-in-place concrete, and has strong construction applicability, high safety coefficient and reasonable manufacturing cost.
