Remote detection system and detection method thereof for construction depth of plastic drainage plates for soft soil foundations

Abstract

The invention relates to a remote automatic detection system for the construction depth of plastic drainage plates for soft soil foundations. The detection system is characterized by comprising a pay-off reel, a remote recording device for the construction depth of the drainage plates and a lifting signal detecting device for a plate inserting machine. A detection method comprises the steps that the drainage plates pass through an encoder measuring wheel of the detection device in the operating process, the encoder measuring wheel detects the operating length of the drainage plates, the operating length is converted into the insertion depth, and therefore the insertion depth of the drainage plates can be detected; and the remote recording device for the construction depth of the drainage plates adopts a lifting type measuring frame, the lifting type measuring frame can be automatically adjusted along with the horizontal operating height of the drainage plates and is kept consistent with the outlet height of the drainage plates all the time, and therefore the detection precision is improved. The remote detection system and the detection method thereof for the construction depth of the plastic drainage plates for the soft soil foundations have the beneficial effects that a comprehensive technology of an automatic remote length recorder and a magnetic sensor of a steel wire rope fixed pulley of the plate inserting machine is adopted in the construction process to record and control the construction length and tape return phenomena of the plastic drainage plates, and therefore continuous detection of the multiple drainage plates on the pay-off reel in the layer-by-layer construction process can be realized.

Description

technical field [0001] The invention belongs to the field of strengthening soft foundations in the construction industry, and in particular relates to a remote detection system and a detection method for the construction depth of plastic drainage boards on soft soil foundations. Background technique [0002] The plastic plate drainage method is a common method for strengthening soft foundations in the construction industry. The method is to insert the plastic slats with longitudinal shallow grooves on the surface into the soft soil with a slotting machine, and then preload (or vacuum preload) on the ground to make the water in the soft soil flow along the vertical channel of the plastic drainage board. escape, so that the foundation can expel moisture and accelerate consolidation. When treating the foundation with this method, the depth of inserting the plastic board into the soft soil and the arrangement density of the inserted plastic board within the range of the treated...

Problems solved by technology

Due to the influence of soil conditions, drilling equipment, operating level and other aspects, a little carelessness will cause large back-up phenomenon, resulting in the bottom mark of the slab being lower than the design requirement, and these exceeding standards often occur during construction

This is mainly due to the unreasonable size of the casing of the drilling machine, too large opening at the lower end, insufficient tightness between the material and size of the pipe shoe and the casing, too fast lifting of the casing, improper operation and other factors.

In addition, the selection of the construction team is an important factor affecting the construction quality that cannot be ignored. The quality of the construction personnel of each construction unit is uneven, and each unit uses a large number of temporary workers. During the on-site supervision, the supervisory engineer found that there are frequent quality vicious accidents such as counterfeit boards and serious tape-backs that have not been reprinted.
