Description
Technical Field
The utility model relates to a shake towards construction technical field, especially relate to a shake towards gravel pile and encrypt quality control device.
Background
The vibroflotation method, also known as vibroflotation method, is a foundation stabilization method developed based on the principle that sandy soil foundation can be compacted by adding water and vibrating, and is later used for arranging vibroflotation replacement gravel piles in cohesive soil layers. The vibroflotation method is one of the effective foundation treatment methods commonly applied at home and abroad, and can achieve the purposes of improving the bearing capacity of the foundation, reducing the settlement of the building foundation, improving the stability of the earth-rock dam body and the foundation and eliminating the liquefaction of the foundation. Has wide application in the fields of industrial and civil constructional engineering, hydraulic and hydroelectric engineering, harbor island engineering and the like.
The conventional vibroflotation pile construction pile body material is preferably made of hard materials such as broken stones, pebbles and gravels with mud content not more than 5%, the particle size is about 20-150 mm according to design requirements, and broken stones need to be loaded into pile holes by a loader in a site matched with vibroflotation conditions.
The prior art has the following problems:
1) the existing vibroflotation pile encryption construction excessively depends on current intensity indexes. The key construction parameter indexes of the existing vibroflotation gravel pile construction process related to vibroflotation pile encryption construction process comprise: current intensity, vibration retention time, water pressure, air pressure, depth and the like, wherein the current intensity is used as a main control index, and the rest are secondary control indexes. In order to prevent the vibroflotation device from being damaged by overlarge current value, an operator usually only pays attention to the current intensity index, when the current value exceeds an allowable value, the operator can quickly lift the vibroflotation device, and other reference indexes cannot be considered at the same time, so that the compactness of the gravel pile is easily uneven.
2) The existing vibroflotation pile is single in compactness evaluation index during encryption construction and lacks of contrast verification index. At present, only a single judgment index of the encryption current intensity exists, and the increase and decrease of the current intensity may be caused by unreal encryption reasons, such as inclination of a vibroflot, uneven contact between the vibroflot and backfill materials, contact of the vibroflot with local hard strata (boulder), overlarge back-inserting depth, overhigh mud content in a hole, overlong working time of a motor and the like. Due to the lack of other evaluation indexes, the operator often mistakenly judges that the current intensity increase caused by the unreal vibroflotation encryption is that the real encryption current intensity reaches the design requirement, and the encryption construction is finished when the design current intensity and the vibration retention time are not actually reached, so that the quality of the vibroflotation pile is difficult to ensure.
3) The existing vibroflotation pile is low in automation degree in encryption construction. The existing vibroflotation encryption construction mainly depends on manual judgment of an operator, and due to the fact that experience, proficiency and operation skill of the operator are different from person to person, the pile forming quality lacks scientific quantitative evaluation standards.
