Embodiment 1

[0048] In this example, a typical foundation pit project in Zhuhai area adopts FLAC 3D The software performs calculations to establish a three-dimensional calculation model of the foundation pit and the enclosure structure. Through numerical simulation, the influence of the reinforcement depth, reinforcement width, arrangement spacing, admixture content and other parameters of the reinforcement soil in the pit on the stability of the foundation pit is studied. Provide theoretical basis for the design and construction of soil reinforcement in pits.

[0049] A deep silt foundation reinforcement method, comprising the following steps:

[0050] Step 1): Use the percussion drilling method to conduct geological survey on the construction site, determine the soil layer and division information, and then drill the core to determine the size of the silt layer and determine the construction area.

[0051] Determine the soil layer from top to bottom as:

[0052]Plain fill, the layer th...

Embodiment 2-5

[0073] A kind of deep silt foundation reinforcement method, the difference with Embodiment 1 is,

[0074] The consumption and selection of each raw material are different, and the temperature in step b) is different, see Table 2 for details, and various parameters of Example 1 are also summarized in Table 2.

Embodiment 6

[0078] A kind of deep silt foundation reinforcement method, the difference with embodiment 5 is,

[0079] The admixture is fly ash, zeolite rock and ceramsite, and the weight ratio of fly ash, zeolite rock and ceramsite is 0.15:1:1.3, that is, the input amount of fly ash is 3.2kg, and the input amount of zeolite rock is 21.2kg, the input amount of ceramsite is 27.6kg.

Abstract

The present application relates to the field of foundation reinforcement, and more particularly, to a method for reinforcement of deep silt foundations. A method for strengthening a deep silt foundation, comprising the following steps: Step 1): carrying out geological survey on a construction site, determining soil layers and dividing information, then drilling and coring to determine the size of the silt layer, and determining a construction area; Step 2): leveling Construction site; Step 3): According to the provided coordinate reference point, carry out stakeout positioning and elevation survey; Step 4): Release the pile position according to construction requirements and measurement control points, place the pile driver in place, and pour concrete; Step 5): Static It has the advantages of improving the driving depth of the pile foundation and also having a good reinforcement effect.

Description

technical field [0001] The present application relates to the field of foundation reinforcement, and more particularly, to a method for reinforcement of deep silt foundations. Background technique [0002] Most of the silty clay has a certain connection function, and is often in a soft plastic state when it is not excavated, and has a certain structure. However, after artificial excavation, the structure was damaged and showed a flowing state, which led to construction difficulties. [0003] In the coastal cities of southeast my country, the urban underground soil is mostly silty. When adding buildings on this foundation, it is necessary to reinforce the silty foundation, otherwise the building will collapse due to the instability of the foundation. [0004] In the related art, the pile foundation is usually driven directly on the surface of the rock layer through the silt texture, so as to achieve the effect of reinforcement. This kind of reinforcement method is used in d...
