Foundation construction technology

Abstract

The invention discloses a foundation construction technology. The foundation construction technology mainly comprises the following steps that S1, a curing agent is evenly sprayed and distributed to the surface of a roadbed foundation, and then coarse aggregates are adopted to be laid and ground and then serve as a cushion layer; S2, a steel bar net layer is bundled to the cushion layer, a layer of a soluble film is laid on the steel bar net layer, and then a semi-rigid lower base layer is evenly sprayed and distributed to the soluble film; S3, a water seepage brick compaction layer is laid onthe upper surface of the semi-rigid lower base layer; S4, a semi-rigid upper base layer is evenly sprayed and distributed to the position above the water seepage brick compaction layer; S5, the position above the semi-rigid upper base layer is filled with a mixed material of gravels and epoxy resin, and then compaction is conducted; and S6, an emulsified asphalt layer for fixing and boding the epoxy resin layer is sprayed and distributed to the compacted mixed material layer. The foundation is good in water seepage performance, the situation of foundation face water accumulation is avoided, and accordingly the effect that foundation vehicle transportation is not influenced is achieved.

Description

technical field [0001] The invention relates to the technical field of foundation construction, in particular to a foundation construction technology. Background technique [0002] At present, in the process of foundation construction, the construction sequence is arranged as follows: temporary access road→cleaning surface and dredging→earthwork filling→drainage construction→branch and drainage pipe construction→pipeline construction→base layer→base surface. For most low-grade foundation surfaces, traditional top-sealing materials (surface resin, petroleum asphalt or emulsified asphalt, etc.) can be opened to traffic after spreading, compacting, and leveling. [0003] However, due to the limitation of the performance of the traditional upper sealing material (mainly its poor viscosity, water resistance and wear resistance), it often occurs within a short time after the construction is completed and opened to traffic due to low water permeability. The occurrence of water in ...

[0003] However, due to the limitation of the performance of the traditional upper sealing material (mainly its poor viscosity, water resistance and wear resistance), it often occurs within a short time after the construction is completed and opened to traffic due to low water permeability. The occurrence of water in the foundation area will eventually affect the opening of the foundation to traffic
