Embodiment Construction

[0038] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0039] Such as figure 1 and figure 2 As shown, this embodiment discloses a gravity foundation structure, which mainly includes a concrete roof 1, a concrete cylindrical ballast tank 2, a cylindrical structure 3 composed of a concrete cylinder wall 31 and a steel cylinder wall 32, and steel sub-structures. deck 4.

[0040] The concrete roof 1 is a circular sheet structure with a diameter of 40m and a thickness of 0.4m. The usual diameter selection range of the concrete roof 1 is 10-50m, and the thickness selection range is 0.2-0.6m.

[0041] The upper surface of the concrete roof 1 is distributed with a structural beam system 5 capable of ensuring the rigidity of the concrete roof 1 , and the bottom surface of the structural beam system 5 is flush w...

Abstract

The invention discloses a gravity type foundation structure and a construction method thereof. A concrete cylinder-type pressure loading cabin is arranged on a concrete top cover; a cylinder structure formed by a concrete cylinder wall and a steel cylinder wall is arranged on the lower side of the concrete top cover; first pipelines are uniformly arranged in the concrete cylinder wall along the radial direction; and a steel subdivision plate is arranged in the internal space of the steel cylinder wall. The construction method comprises the following steps of: prefabricating the gravity type foundation structure on the land; transporting the whole foundation to a construction site in a floating mode, and performing self-weight sinking construction and negative pressure sinking construction; after the negative pressure sinking construction is stopped, performing groundbreaking sinking construction through the first pipelines; performing grouting operation through the first pipelines and second pipelines on sub-cabins; and filling heavy objects in the concrete cylinder-type pressure loading cabin, performing ballasting operation, and simultaneously performing riprap ballasting operation above the concrete top cover and at the periphery of the concrete cylinder-type pressure loading cabin. By the structure and the method, transportation and construction difficulties can be reduced, transportation and installation speeds can be increased, and the applicability to a soil body can be enhanced, so that a construction period is shortened, and engineering cost is substantially reduced.

Description

technical field [0001] The invention relates to a basic structure, in particular to a basic structure in port, ocean, water conservancy and bridge engineering and a construction method thereof. Background technique [0002] At present, in port, marine, water conservancy and bridge projects, the common foundation forms mainly include pile foundation, bracket foundation, gravity foundation and cylinder foundation. The gravity foundation is a structure that relies on the structure itself and the weight of the filler or ballast on it to resist external forces and maintain the building's anti-sliding and anti-tilting stability. Since its structural materials are generally concrete and sandstone materials, the material cost is relatively low , and generally in the form of shallow foundations, the construction cost is also low, so it is gradually recognized and widely used in the engineering field. [0003] However, due to the heavy weight, the gravity foundation is relatively dif...
