Problems solved by technology

There is a certain angle between the underground pile foundation and the gentle slope section, and improper handling will cause stress concentration, which is not conducive to the stable operation of energy dissipation facilities
Especially when the flood comes, the stress at the joint between the base plate and the pile foundation is too large, which is extremely unfavorable to the stability, and the base plate is often overturned, which affects the operation of the project

Abstract

The invention relates to a balanced force transfer device for a concrete slope pile foundation. The balanced force transfer device for the concrete slope pile foundation comprises a force-bearing galvanized steel sheet and multiple groups of force transfer reinforcing steel bars, wherein the lengths of the force transfer reinforcing steel bars are different; the top ends of the force transfer reinforcing steel bars are inclined planes; the force-bearing galvanized steel sheet is arranged at the top ends of the force transfer reinforcing steel bars; each group of force transfer reinforcing steel bars is sequentially fixed onto a slope pile from short to long; and the top ends of each column and each row of force transfer reinforcing steel bars are connected to form a straight line. A construction method comprises the steps of calculating the area of the required force-bearing galvanized steel sheet and the number and the sizes of the required force transfer reinforcing steel bars according to the pressure borne by the force transfer device, and designing installing and fixing positions of the force transfer reinforcing steel bars on the force-bearing galvanized steel sheet; sequentially fixing the force transfer reinforcing steel bars onto the force-bearing galvanized steel sheet according to a sequence from short to long so as to form a support component; horizontally placing connecting steel plates at the lower ends of the force transfer reinforcing steel bars on the slope pile; and paving concretes on the connecting steel plates for casting with the slope pile into a whole. The balanced force transfer device for the concrete slope pile foundation and the construction method provided by the invention are mainly applied to water conservancy project energy dissipation devices, so that a load applied by an upper-layer concrete plate is uniformly borne by the pile foundation.

Description

technical field [0001] The invention relates to the field of energy-dissipating facilities of water conservancy projects, and more specifically, relates to a balanced force transmission device and a construction method for concrete slope protection pile foundations. Background technique [0002] The safe operation of water conservancy projects is closely related to the effectiveness of downstream energy dissipation facilities. During the flood season, the flow of incoming water is large and the flow velocity is fast, which will have an adverse impact on downstream energy dissipation and anti-scour facilities. In the design, a gentle slope section is often provided on the upstream of the stilling pool to connect the upstream discharge structure, so as to reduce the erosion of the water flow on the downstream floor and ensure the normal use of the stilling pool. In the actual construction process, the construction quality of the connection section is often related to the conne...
