Problems solved by technology

[0007] In order to fundamentally solve the problem of uneven settlement at the bottom of substation buildings built on soft soil foundations, the inventor, after long-term research, proposed the technical solution of the present invention, that is, considering The ground floor ±0.000 floor below the indoor ground is used as a structural layer to transfer all the upper loads to the foundation of the building

Embodiment Construction

[0021] The processing method of the present invention will be further described in detail below by taking a part of the 35kv device room as an example in conjunction with the accompanying drawings.

[0022] A large number of equipment and cable trenches are arranged indoors in the ground floor of the 35kv device room. In order to meet the needs of the cable channel, in the structural design, first determine to add a structural layer at a position near -1.1 meters below the 0.000 layer. The specific method is as follows:

[0023] A cap 1 is set under the frame column of the building. In order to reduce the height and reinforcement of the foundation beam of this floor, in the mid-span of the 35kv device room, a cap 1 is added as required at the position of -1.1m below the 0.000 floor ;Arrange a corresponding number of foundation beams 6 at the position of -1.1 meters with the bearing platform as the fulcrum; arrange a layer of 150mm thick reinforced concrete slab 9 at the positi...

Abstract

The invention discloses a method for treating the bottom structure of a building in a substation. In the method, a bearing platform, a foundation beam positioned above the bearing platform and a reinforced concrete board structural layer positioned above the foundation beam are arranged at the bottom of the building. The treatment method is easy to construct and thoroughly solves the problem of the differential settlement of the building bottom in the substation on a soft soil foundation.

Description

technical field [0001] The invention relates to the technical field of building foundation treatment, in particular to a treatment method for building substructures suitable for soft soil foundations. Background technique [0002] When constructing the foundations of buildings, it is a known method to connect concrete foundation beams to concrete piles driven into the ground to provide good foundation support for subsequent construction work. Generally, only conventional design methods such as ribs and rib beams are used on the bottom of the building, or only plain soil ramming or pond slag backfilling is used for treatment, without the need to improve or enhance the stress of the bottom layer. [0003] Due to the large load of related equipment placed in the building of the substation, such as switch cabinets and other equipment placed on the ground floor of the 35kv device room, main control building, relay room, etc., the underlying structure of the building in the substa...
