Underwater foundation grouting full weight monitoring system and method

Abstract

The present invention discloses an underwater foundation grouting full weight monitoring system and method, wherein by arranging two level instruments of which the monitoring directions are mutually vertical in a structure and respectively arranging two pressure gauges at the highest position and the lowest position of the grouting space, and according to the pressure data monitored by the two pressure gauges and the horizontal data monitored by the two level instruments, whether the grouting in the grouting space is in full weight is determined; by analyzing the change rule of the pressure data on the two pressure gauges, the state of the grouting is determined, and when the change value of the horizontal data monitored by the level instruments reaches a set value, the pressure of the grouting approaches the anti-buoyancy of the structure, thereby representing that the grouting reaches the full weight. Therefore, regardless of the rigid grouting space or the flexible grouting space onthe weak conditions, such as a natural foundation porous condition, etc., to which the monitoring system and the monitoring method are applied, the monitoring system and the monitoring method both can monitor the full weight state of the grouting accurately, thereby guaranteeing the quality of an underwater foundation grouting engineering.

Description

technical field [0001] The invention relates to the technical field of underwater grouting, in particular to a system and method for monitoring the plumpness of underwater foundation grouting. Background technique [0002] At present, during grouting construction of underwater foundation, the control of grouting plumpness is the most concerned issue of project quality. Generally, there are two methods to control the fullness of grouting: one is to pre-calculate the volume of the space that needs to be injected, and the injected grouting material volume is greater than the calculated amount, which is considered full. This method has a large uncertainty because the injection space is not large It must be a rigid space, and the grouting material may expand the space that needs to be injected under pressure, making the estimated volume of the injection space inaccurate, resulting in insufficient final grouting, and a high risk of later settlement. The other is the observation m...

Problems solved by technology

[0003] The purpose of the present invention is: the existing technology cannot accurately detect the fullness of the underwater foundation grouting, and the technical problem that the grouting is not full is easy to occur, so that the project quality cannot be guaranteed
