The following describes a pressure relief structure applied to a wind power mixing tower foundation tensioning cell according to the present utility model with reference to fig. 1 to 2. The pressure relief structure applied to the wind power mixing tower foundation tensioning chamber is improved on the basis of the tensioning chamber, and comprises the following components: a concrete inverted arch 1, a concrete cushion layer 2 and a filling layer 3.
Wherein the concrete inverted arch 1 is positioned at the bottom of the tensioning chamber; the concrete cushion layer 2 is paved at the bottom of the inverted arch; the filling layer 3 is arranged on top of the inverted arch.
Specifically, the concrete inverted arch 1 having a thickness of not less than 20cm is designed, and the geometrical dimensions of the inverted arch are determined by a designer based on actual stress calculation. The concrete cushion layer 2 is also laid on the bottom layer of the concrete inverted arch 1 as a cushion layer in the same shape as the concrete inverted arch 1. The filling layer 3 covers the top of the concrete inverted arch 1, and light materials such as wood boards, steel plates and the like can be selected to be placed on the concrete inverted arch 1 so as to achieve the aim of leveling the inside of the foundation.
According to the pressure relief structure applied to the wind power mixing tower foundation tensioning chamber, the concrete inverted arch 1, the concrete cushion layer 2 and the filling layer 3 are arranged at the bottom of the tensioning chamber, so that the pressure relief structure is formed, and the concrete inverted arch 1 has the functions of dispersing water and soil pressure and adjusting foundation stress and can prevent the bottom plate from rising and deforming; further, the inverted arch structure fully exerts the compression performance of the concrete, and achieves the purpose of reducing the thickness of the concrete bottom plate and the consumption of the steel bars.
In one embodiment of the present utility model, a reinforcement arch is provided inside the concrete inverted arch 1, and the reinforcement arch includes: the plurality of annular ribs 31 and the plurality of longitudinal ribs 32 are sequentially nested along the circle center of the bottom of the tensioning chamber; the longitudinal ribs 32 are connected to the annular ribs 31 in the diametrical direction of the bottom of the tensioning cell. In this embodiment, the annular ribs 31 and the longitudinal ribs 32 are connected to form a mesh structure, that is, as shown in fig. 2, the plurality of annular ribs 31 are nested with the center of the bottom of the tensioning cell as the center, and the longitudinal ribs 32 are radially connected to the annular ribs 31 along the diameter direction, which is used as the skeleton structure of the concrete inverted arch 1. Specifically, the shape and direction of the annular rib 31 are consistent with the circular shape of the bottom of the tensioning chamber, the longitudinal rib direction is consistent with the diameter of the bottom plate, and the two types of steel bars are arranged inside the concrete inverted arch 1 and fixed through binding or welding and other connecting modes.
