Problems solved by technology

[0002] The watershed in the southwest region has become the main battlefield for hydropower development in my country. This region has the characteristics of complex geological conditions, high seismic fortification intensity, and deep covering layers. In some parts, there are thicker and weak underlying layers, which bring many technologies to dam construction. Difficult, the depth of the foundation pit can reach 40m, especially the support design of the water inlet, the support structure needs to have two functions of support during the construction period and water diversion during the operation period, and the traditional high retaining wall is weak because of the underlying layer It is difficult to meet the requirements on the anti-sliding stability of the base and the anti-sliding stability of the deep layer, and there is also a large risk in the stability of the slope of the foundation pit.

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as Figure 1 to Figure 5 The frame-style connecting wall support structure of the deep foundation pit for damming shown includes a frame-shaped connecting wall structure 2 and an empty box buttress section 1 arranged on the top of the frame-shaped connecting wall structure 2. The wall section 1 includes a retaining wall with an empty box 11 inside and a buttress structure 12 arranged on the side of the retaining wall. The buttress structure 12 faces the horizontal load direction 3, wherein the frame-shaped connecting wall structure 2 is arranged at the bottom On the weak substratum foundation 21.

[0018] During actual construction, the bottom of the dam-building deep foundation pit frame-style ground connection wall support structure is set on the weak underlying layer foundation 21 to handle the weak foundation. A cover plate of a certain thickness is p...

Abstract

The invention relates to the field of damming deep foundation pit supporting, in particular to a damming deep foundation pit frame type diaphragm wall supporting structure. The damming deep foundation pit frame type diaphragm wall supporting structure is used for supporting a horizontal load in a construction period and has a water diversion and flow guide function in an operation period so as to save cost. The damming deep foundation pit frame type diaphragm wall supporting structure comprises a frame type diaphragm wall structure and an empty box buttress section arranged at the top of the frame type diaphragm wall structure, the empty box buttress section comprises a retaining wall internally provided with an empty box and a buttress structure arranged on the side face of the retaining wall, the buttress structure faces the horizontal load direction, and the bottom of the frame type diaphragm wall structure is arranged on a soft underlying layer foundation. The damming deep foundation pit frame type diaphragm wall supporting structure is particularly suitable for deep foundation pit supporting design of a hydropower station water inlet and the like needing the operation period flow guiding function.

Description

technical field [0001] The invention relates to the field of deep foundation pit support for dam building, in particular to a frame-shaped connecting wall support structure for deep foundation pit for dam building. Background technique [0002] The watershed in the southwest region has become the main battlefield for hydropower development in my country. The region has the characteristics of complex geological conditions, high seismic fortification intensity, and deep covering layers. There are even thicker and weak underlying layers in some parts, which brings many technologies to dam construction. Difficulties, the foundation pit depth can reach 40m, especially the support design of the water inlet, the support structure must have two functions of support during the construction period and water diversion during the operation period, and the traditional high retaining wall is weak due to the underlying It is difficult to meet the requirements on the anti-sliding stability of...
