Problems solved by technology

The existing prefabricated foundation mostly adopts prefabricated concrete slat-section steel composite structure and concrete solid slab-column structure. The bottom area of ​​the composite structure foundation is small, which is not suitable for soft soil areas with groundwater. Sometimes it is necessary to install protruding ground beams under the bottom plate, and the bottom surface of the foundation pit is uneven, which will cause certain troubles to the excavation of the foundation pit and the pouring of the cushion layer. There are many connecting bolts between the ground beams, plates, and columns, which is inconvenient to install.

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the drawings.

[0031] Such as figure 1 As shown, the tile assembly type foundation of the present invention includes a column 1, a bottom plate 2 and a rib beam 3. The column 1 is arranged above the middle of the bottom plate 2. The ribs 3 are in four groups, distributed evenly on the outer circumference of the column in a radial shape, and are fixed on the upper end surface of the bottom plate 2.

[0032] Combine figure 2 , The column 1 includes upper and lower layers, the upper layer is a truncated cone 11, and the lower layer is a hollow cylinder 12. The lower part of the truncated cone 11 is hollow and communicates with the hollow part of the lower hollow cylinder 12 to form a cylindrical hollow part 13 together. The truncated cone 11 is composed of four frustum tiles 14 of the same size, and the four frustum tiles 14 are symmetrically distributed along the central axis of the truncated cone ...

Abstract

The invention discloses a concrete assembly type foundation. The concrete assembly type foundation comprises an upright pillar and a bottom plate, wherein the upright pillar is arranged above the bottom plate; and the upright pillar is in a shape of a cone frustum, and the lower part of the upright pillar is hollow. The assembly type foundation adopts sectional and fragmented design. Each component is flaky or is in a shape of a tile, such as a roof tile, the size and weight of single component can be effectively controlled, and the components are convenient to prefabricate in a factory and convenient to transport and mount. The factory processing of the foundation components, mechanical construction and the reutilization of resources can be realized, and the deep conduction of line whole-process mechanical construction is facilitated.

Description

Technical field [0001] The invention relates to a concrete assembly type foundation, in particular to a tile structure assembly type foundation. Background technique [0002] With the development of my country's economy and the increase of line transmission capacity, in power line engineering, the guyed towers and prefabricated foundations that were used in large quantities in the early days have gradually been replaced by self-standing towers and cast-in-place foundations. [0003] However, the cast-in-place foundation construction has problems such as slow construction speed, high labor intensity, and poor construction environment. Some construction methods fail to fully consider the requirements of environmental protection, which is far from the world's advanced level. The prefabricated foundation realizes modular design, factory processing, and mechanized construction of basic components, which greatly reduces the amount of artificial wet work and procedures on site, and improv...
