Problems solved by technology

The air pressure splitting vacuum preloading method is newly proposed. Only a small amount of indoor research and small-scale field tests have been carried out in the Institute of Geotechnical Engineering of Southeast University, but it is far from deep enough.
In order to comprehensively promote the application of air pressure splitting vacuum preloading method for soft soil foundation treatment, it is necessary to carry out systematic experimental research to explore the reinforcement mechanism, process and construction control methods and measures of air pressure splitting vacuum preloading method. There is no special device for the model test of soft soil reinforced by air pressure splitting and vacuum preloading method, and corresponding test devices need to be developed

Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0029] Such as figure 1 Shown: an indoor model test device of air pressure splitting vacuum preloading method, including model tank, stacking system, vacuum loading system, air pressure splitting system and measurement system;

[0030] The model tank is composed of a plastic drum 1, a plastic drum base 2, a plastic drum top cover 3, and steel bars 4; wherein the plastic drum 1 is an organic transparent plastic drum with a diameter of 50 cm and a height of 120 cm. The plastic drum base 2 is a high-strength plastic plate (PVC) or steel plate with a thickness of 2 cm and a diameter of 60 cm; the plastic drum top cover 3 is made of the same material as the base. The plastic drum base 2 is completely sealed with the plastic drum 1. The plastic drum base 2 and the plastic drum top cover 3 have round holes with a diameter of 10mm and threads, which are u...

Abstract

The invention discloses an indoor model testing device employing an air-pressure splitting vacuum preloading method. The indoor model testing device comprises a model groove, a pile-loading system, a vacuum loading system, an air-pressure splitting system and a measuring system, wherein the model groove comprises a plastic cylinder, a plastic cylinder base, a plastic cylinder top cover and reinforcing steel bars; the pile-loading system is a lever type loading device; the vacuum loading system comprises a drainage system, a sealing system and a vacuum-pumping system; the air-pressure splitting system comprises an air nozzle, an air conveying pipe, a pressure flow speed controller and an air compressor; and the measuring system comprises a displacement sensor, a pore water pressure meter and a data acquirer. The invention also discloses an application method of the indoor model testing device employing the air-pressure splitting vacuum preloading method. The indoor model testing device is reasonable and simple in structure and convenient to operate and can be used for performing model test of reinforcing soft soil by using the air-pressure splitting vacuum preloading method.

Description

technical field [0001] The invention relates to the field of soft soil foundation reinforcement, and more particularly relates to an air pressure splitting vacuum preloading method for strengthening a soft soil model test device and a test method, which are suitable for the air pressure splitting vacuum preloading method for strengthening soft soil model tests. Background technique [0002] Soft soil foundation treatment is a technical problem often faced by engineering construction in coastal areas along the river in my country. Especially in southeastern coastal areas of my country, deep marine soft soil treatment is one of the key technologies for urban construction, port engineering, and transportation facility construction. [0003] Commonly used soft soil foundation treatment methods include replacement and filling method, drainage consolidation method, cement-soil mixing method, gravel and sand pile method, grouting method, vibrating method, geopolymer and underpinning...
