Connecting device for uplift pile and water-resistant plate

Abstract

The invention discloses a connecting device for an uplift pile and a water-resistant plate, and relates to the field of uplift piles and water-resistant plates, the connecting device comprises a prestressed pipe pile with a non-cut pile head and the water-resistant plate, the pile head of the prestressed pipe pile extends into a local thickening area of the water-resistant plate, and an inner core of the prestressed pipe pile is plugged with a thick steel plate; annular steel plates are welded to the outer sides of the pile ends of the prestressed pipe piles. The connecting joint of the uplift pile and the water-resistant plate is clear in stress, simple in construction, capable of ensuring the quality of the connecting joint, high in construction speed, capable of effectively accelerating the construction progress of a project and further saving the construction cost of the project. And the next construction procedure can be carried out after the device is welded on site without waiting for a certain time, so that the time is greatly saved.

Description

technical field [0001] The invention relates to the field of uplift-resistant piles and water-resistant plates, in particular to a connection device used for up-lift-resistant piles and water-resistant plates. Background technique [0002] In recent years, due to the frequent occurrence of extreme climates and the rise of urban groundwater levels, accidents caused by building anti-floating failures have increased year by year. In engineering, anti-floating measures are divided into two categories: active anti-floating measures and passive anti-floating measures. The uplift piles and anti-floating anchors used in the project belong to passive anti-floating measures, and the anti-floating anchors are divided into prestressed anchors and non-prestressed anchors according to the stress mode of the anchoring section of the anchors. [0003] Prestressed anchors are used less in projects due to the complex construction procedures on site and higher cost, while non-prestressed anch...

Problems solved by technology

[0004] At present, the connection between the uplift pile and the anti-water board is connected by mechanical sleeves and interpolated reinforced concrete on the end plate of the uplift pile. Due to the limitation of the site conditions and the differences in the operation level of the on-site construction workers, the interpolation The quality of concrete pouring directly affects the bearing capacity of uplift piles

At the same time, the current connection method takes a long time, which affects the progress of the project and increases the workload of the construction personnel.

Because after pouring core concrete, it takes 28 days for the concrete strength to meet the design requirements, which wastes a lot of time and affects the construction efficiency. Therefore, the common anti-pull prefabricated pile joints are divided into mechanical sleeve connection and inner core connection. The amount of reinforcement used in this method is relatively large, and the construction period is relatively long
