Embodiment Construction

[0023] The present invention is described in detail below in conjunction with accompanying drawing:

[0024] Aiming at the lack of bearing capacity of existing pile group foundations bearing horizontal loads, the invention provides a combined foundation form with low engineering cost and shortened construction period, and reasonably increases the level of the upper soil body through the combined foundation of horizontal loaded pile 1 + underground diaphragm wall 2 ability, reducing the quantity and length of the horizontal loaded pile 1.

[0025] Such as Figure 1-2 As shown, the present invention constitutes a combined foundation capable of bearing horizontal loads by combining horizontal load-bearing piles 1 and underground diaphragm walls 2, consisting of upper underground diaphragm walls 2 and lower horizontal load-bearing piles 1, and the top of underground diaphragm walls 2 The roof 5 and the top of the horizontal loaded pile 1 are embedded in the underground continuous...

Abstract

The invention discloses a horizontal bearing combined foundation based on piles and an underground continuous wall and a method.The horizontal bearing combined foundation comprises the underground continuous wall and the multiple horizontal load-bearing piles arranged underground, a top plate is arranged at the top face of the underground continuous wall, the horizontal load-bearing piles are embedded into the bottom face of the underground continuous wall, and the combined foundation is used for bearing horizontal loads.The piles and the underground continuous wall are combined to serve as the foundation bearing horizontal loads, the advantage of high horizontal rigidity of the underground continuous wall is brought into play, and meanwhile embedding of the foundation is guaranteed through the piles on the lower portion.

Description

technical field [0001] The invention relates to a horizontal bearing composite foundation, in particular to a horizontal bearing composite foundation based on piles and an underground continuous wall and a method thereof. Background technique [0002] In various projects such as power engineering, water conservancy engineering, and high-rise buildings, there are a large number of buildings (structures) that often make the structure bear a large horizontal load due to the particularity of the process. For example: in electric power engineering, auxiliary buildings such as coal storage sheds may cause sideways movement of the building foundation due to the large-area indoor load; in marine engineering, such as offshore transmission towers, offshore wind turbines, etc. , Horizontal earthquake force, ship impact force and other horizontal loading forces. In the design of these engineering objects, the horizontal load often becomes its control load in the foundation design. At ...
