Description

Plastic drainage plate inserting plate structure for soft soil foundation

Technical Field

The utility model belongs to the technical field of soft soil foundation dewatering construction technique and specifically relates to a plastics drain bar picture peg structure for soft soil foundation.

Background

The vertical plastic drainage plate is used for treating the soft roadbed, and the plastic drainage plate is used for draining water in the roadbed so as to increase effective stress acting on soil particles to accelerate roadbed consolidation settlement and achieve the purpose of improving strength. The plastic drain board method is one form of drainage consolidation. The drainage consolidation method is that vertical drainage bodies such as sand wells or plastic drainage plates are arranged in the roadbed, and then the vertical drainage bodies are gradually loaded by grading according to the weight of the building; or before the roadbed is filled, the site is firstly loaded with prepressing (or vacuum prepressing) to discharge pore water in the soil body, so that the pore water is gradually consolidated, the roadbed is settled, and the strength is improved.

The construction process of the plastic drainage plate occupies a great position in soft foundation treatment engineering due to the advantages of high construction speed, low construction cost and the like, the driving of the plastic drainage belt is a key ring in soft foundation treatment, and the quality of the driving quality is directly related to the quality of drainage consolidation effect.

In the construction time, the plastic drainage plate needs to be inserted into the soil by means of a plate inserting machine. After the board inserting machine is in place, the board inserting machine sinks by aligning to the jack position through the vibration hammer, the plastic drainage board penetrates through the sleeve and is connected with the anchor shoe at the end, the sleeve props against the anchor shoe to insert the plastic drainage board to the designed soil penetration depth, after the sleeve is pulled up, the anchor shoe and the plastic drainage board are left in the soil together, and then the continuous plastic drainage board is cut off, so that the board inserting operation of one drainage hole is completed. When the sleeve is pulled back, the plastic drainage plate generates a back-banding phenomenon which is a common problem and mainly shows that the soft soil flow-molding phenomenon is common in deep soft soil, and when the sleeve is pulled back, the anchoring effect of surrounding soil on an anchor shoe is weaker, so that when the sleeve is pulled back, the plastic drainage plate is always lifted to a length along the strip, so that the plastic drainage plate deviates from the preset inserting plate depth and is commonly called as the back-banding phenomenon, and the back-banding phenomenon generates adverse effects on the standardized construction of the engineering.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a plastics drain bar picture peg structure for soft soil foundation helps reducing the phenomenon of bringing back of plastics drain bar with plastics drain bar anchor in the weak soil.

The above object of the present invention can be achieved by the following technical solutions:
