A steel plate combined steel pipe concrete drainable manhole cover

Abstract

The invention discloses a drainable manhole cover with combined steel plates and concrete filled steel tubes. The drainable manhole cover comprises a concrete cover body (1), wherein a steel plate (2) is embedded in a bisecting surface in the thickness direction of the concrete cover body (1), cylindrical steel tubes (3) symmetrically distributed about the steel plate (2) are connected with the upper surface and the lower surface of the steel plate (2), and drain pipes (5) penetrating through the upper surface and the lower surface of the concrete cover body (1) are arranged in the steel tubes (3). According to the drainable manhole cover with the combined steel plates and concrete filled steel tubes, the steel plate (2) is embedded in the concrete cover body (1), the upper surface and the lower surface of the steel plate (2) are symmetrically connected with the steel tubes (3), the drain pipes (5) are introduced in the steel tubes (3), the distribution of the steel tubes (3) can be regulated and changed according to the shape of the manhole cover and the stress situation, and because the steel plate (2) and the steel tubes (3) are common components, the manufacturing cost is relatively lower. The design of gaps of the steel tubes (3) can enhance connection between the steep tubes (3) and concrete, can also bear corresponding load, and enhances the strength of the manhole cover; and the drain pipes (5) can drain water on the basis of not influencing a reinforcement structure.

Description

technical field [0001] The invention relates to a well cover, in particular to a connection and strengthening structure and a drainage structure in the well cover. Background technique [0002] In recent years, with the large-scale development of urban road construction, the quality of road manhole covers has caused more and more safety problems. The structure of the manhole cover itself is unreasonable. One of the reasons for this unreasonable structure is that the manhole cover manufacturing cost is too high or the function is missing, especially the drainage structure and strengthening structure. Announcement day 2016.02.03) discloses a kind of novel anti-theft manhole cover, and CN204940347U (announcement date 2016.01.06) discloses a kind of inspection well cover with greening function again, this kind of technical scheme expands the functionality of well cover itself, and It has a reinforced structure, but at the same time, some problems are ignored, that is, the relia...

[0002] In recent years, with the large-scale development of urban road construction, the quality of road manhole covers has caused more and more safety problems. The structure of the manhole cover itself is unreasonable. One of the reasons for this unreasonable structure is that the manhole cover manufacturing cost is too high or the function is missing, especially the drainage structure and strengthening structure. Announcement day 2016.02.03) discloses a kind of novel anti-theft manhole cover, and CN204940347U (announcement date 2016.01.06) discloses a kind of inspection well cover with greening function again, this kind of technical scheme expands the functionality of well cover itself, and It has a reinforced structure, but at the same time, some problems are ignored, that is, the reliability of the connection between the concrete layer and the reinforced structure and the drainage function
