Foundation suitable for traffic rod piece and construction method

Abstract

The invention provides a foundation suitable for a traffic rod piece and a construction method, and relates to the field of municipal construction. The foundation comprises a base, wherein a slotted hole is formed in the base, a rubber ring is coaxially arranged in the slotted hole in a matched mode, the outer circumferential surface of the rubber ring is attached to the inner wall of the slottedhole, protruding blocks and grooves are formed in the inner circumferential surface of the rubber ring alternately, the protruding blocks and the grooves are sequentially formed in the circumferentialdirection of the rubber ring alternately to form a tooth-shaped structure and used for making contact with and abutting against the outer wall of the coaxially-matched rod piece, the prefabricated base is adopted to cooperate with a preformed hole, the rod piece is directly installed on the foundation in an inserted connection mode, a traditional connecting mode of the rod piece and the foundation is changed, the rod piece can be accurately positioned and restrained after the base is leveled, prefabrication and assembly of the foundation are achieved, the construction precision is improved, the construction speed is increased, and the engineering cost is saved.

Description

technical field [0001] The present disclosure relates to the field of municipal construction, in particular to a foundation and a construction method suitable for a traffic pole. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] The foundations of urban road traffic poles are mostly independent rectangular cast-in-place concrete foundations, and the bottom of the column forms a rigid connection with the foundation through the embedded stud bolts and the flange structure. [0004] The road construction unit is responsible for the construction of the traffic foundation as the civil engineering part in the municipal engineering, and the traffic poles and signs and facilities are separately tendered or commissioned. The traffic poles are mostly located in the central green belt of the road and the non-mechanical separation belt. Because they are at the en...

AI Technical Summary

Problems solved by technology

[0005] The inventor found that at present, when the foundation is poured, the space on both sides is limited, and it is difficult to install the side formwork and standardize the construction. The plane layout of the column bolts and the level control of the foundation flange are affected by on-site factors, and the installation accuracy is difficult to meet the installation requirements of the later rods. The on-site maintenance of concrete also prolongs the construction period; when the upper member is installed, the processing manufacturer often needs to make secondary adjustments on site (bolt positioning, flange leveling), and even reaming the bolt holes of the flange plate at the bottom of the member. The efficiency and efficiency are low; the anti-corrosion measures at the bottom of the column are traditionally encapsulated with concrete, which is large in size, easy to crack and unsightly, and cannot achieve a good anti-corrosion effect at the bottom of the column after cracking
