Description
Technical field
Measure bored concrete pile and diaphram wall sediment thickness field when the invention belongs to geotechnical engineering construction, particularly relate to a kind of instrument and method of sediment thickness when measuring bored concrete pile and construction of diaphragm wall.
Background technology
At present, bored concrete pile and diaphram wall are applied in base pit engineering very at large.Bored concrete pile can be used as the engineering pile bearing upper floor load, the fender post of enclosing foundation ditch periphery soil body when also can be used as excavation of foundation pit.Diaphram wall is usually used as the enclosure wall taking into account gear soil and sealing during excavation of foundation pit.When bored concrete pile or construction of diaphragm wall, be all adopt different specialized equipment construction pore-creatings or grooving on the ground.In work progress, for ensureing the stable of stake holes or cell wall, the mud meeting field geology conditions, there is certain weight proportion must be prepared, inject in stake holes or groove and carry out retaining wall, prevent the soil body on hole wall or cell wall from caving in.In pore-forming or grooving process, can suspend in slurry coat method the impurity such as a large amount of grit, micro-sand, and can sink gradually, formed at the bottom of hole or the sediment of trench bottom.If these sediments are thicker, the construction quality of bored concrete pile and diaphram wall can be affected.
For measuring at the bottom of bored concrete pile and construction of diaphragm wall hole when or the sediment thickness of bottom land, existing measuring method mainly adopts chaining pin and surveys at the bottom of cake difference measured hole or the maximum submergence depth of bottom land, and difference is between the two sediment thickness.Under normal circumstances, chaining pin is the long reinforcing bar of 40cm or weight, and to survey cake be a diameter is the steel disk of 15cm.Chaining pin and survey cake have separate type and integral type two kinds.Compared with separate type, integral type chaining pin more easily drops on same position with survey cake, and the sediment thickness recorded is comparatively accurate.But no matter adopt which kind of mode, with bar dowel as chaining pin, at mud viscosity, excessive or suspension is too much slowly deep and slow at present, and is difficult to be inserted into bottom sediment, and the sediment thickness error recorded is larger.In addition, surveyed when up promoting, this chaining pin is easily blocked should not extract by sediment, suspension.
Through finding prior art literature search, the sediment thickness error that existing instrument records is comparatively large, be unfavorable for promoting.As the weight measuring method that Liang Qixin adopts in " method of sediment thickness at the bottom of weight measured hole ", twice measurement is more loaded down with trivial details, and excessive slowly deep and slow at present at mud viscosity, and promote also more difficult, the sediment thickness error recorded is also larger.
