Embodiment Construction

[0009] In order to further understand the invention 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:

[0010] see figure 1 , the present invention is based on a foundation reinforcement method based on cylindrical foundation negative pressure technology, comprising the following steps:

[0011] (1) Open a reserved negative pressure hole on the top cover plate of the cylindrical foundation, and lay geotextile and other permeable / air-permeable materials under the top cover plate of the cylindrical foundation;

[0012] (2) According to the set penetration negative pressure value, the negative pressure of the cylindrical foundation is lowered into place;

[0013] (3) The water / air pump draws water and / or air through the reserved negative pressure holes, and carries out negative pressure foundation reinforcement treatment according to the set foun...

Abstract

The invention discloses a foundation reinforcement method based on bucket foundation negative pressure technology, which comprises the following steps: (1) opening negative pressure preformed holes on a bucket top cover plate of bucket foundation, and laying geotextile below the bucket top cover plate of the bucket foundation; (2) according to the set penetration negative pressure value, sinking and positioning bucket foundation negative pressure; and (3) pumping water and/or air through the negative pressure preformed holes by a water/air pump, and performing negative pressure foundation reinforcement treatment according to the set foundation soil precompression value to realize the overconsolidation of foundation soil. The method performs overconsolidation treatment on the foundation soil by using a foundation body through the attraction force applied by the water/air pump, and reinforces the foundation; and shallow foundation is reinforced effectively and evenly through the geotextile and other permeable and breathable materials laid between the top of a bucket and the foundation soil, the bearing capacity and the stability of the bucket foundation are improved, and the method has outstanding foundation reinforcement effect, simple use equipment, simple and convenient construction, short construction period, obvious economic benefit, and low comprehensive construction cost.

Description

technical field [0001] The invention relates to a foundation reinforcement treatment method in port, ocean, water conservancy and bridge engineering, in particular to a foundation reinforcement method based on the negative pressure technology of a cylindrical foundation. Background technique [0002] At present, in port, ocean, water conservancy and bridge engineering, especially on silty soil, the settlement problem of the cylindrical foundation as a shallow foundation is the main problem in the application of the cylindrical foundation. In this area with unfavorable geological conditions, it is difficult for the barrel foundation to meet the requirements of bearing capacity and stability. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides a foundation reinforcement method based on the negative pressure technology of the cylindrical foundation, which can improve the bearing capacity and stabi...
