Abstract
The invention relates to a tool and method for measuring the thickness of sediment during construction of cast-in-place piles and underground diaphragm walls. The tool comprises a shuttle-type measuring pin, a circular vertical sleeve, a circular cake-shaped measuring piece and measuring ropes. A screw cap connected with the measuring rope I is arranged at the top end of the shuttle-type measuring pin. The circular vertical sleeve is connected with a base plate of the circular cake-shaped measuring piece through four steel nails, wherein the four steel nails are evenly distributed on the edge of a base plate of the circular vertical sleeve, and the head portions and the tail portions of the steel nails are removed. Two circular holes which are coaxial and equal in size are formed in the center of the circular vertical sleeve and the center of the circular cake-shaped measuring piece respectively. Hollow cylinders equal in size are welded in the two circular holes respectively. Four matched screw caps are evenly distributed at the top end of the hollow cylinder of the circular vertical sleeve and used for binding one ends of four measuring ropes II equal in length respectively, and the other ends of the four measuring ropes II are knotted together and are then connected with a single measuring rope II. The shuttle-type measuring pin can penetrate through the two hollow cylinders successfully. The tool is accurate in measurement and convenient to operate; the resistance caused when the measuring pin sinks and is lifted is greatly reduced, the measuring pin can be accurately inserted into the bottom of the sediment, and therefore the accuracy in measuring the thickness of the sediment is guaranteed.
Description
Technical field
While the invention belongs to geotechnical engineering construction, measure castinplace pile and diaphragm wall sediment thickness field, relate in particular to a kind of instrument and method of sediment thickness while measuring castinplace pile and construction of diaphragm wall.
Background technology
At present, castinplace pile and diaphragm wall are applied in base pit engineering very at large.Castinplace pile can be used as the engineering pile that bears upper floor load, the fender post of the enclosing foundation ditch periphery soil body while also can be used as excavation of foundation pit.Diaphragm wall is taken into account the enclosure wall of gear soil and sealing during usually used as excavation of foundation pit.When castinplace pile or construction of diaphragm wall, be all to adopt on the ground different special equipment construction pore-creating or grooving.In work progress, for guaranteeing the stable of stake hole or cell wall, must prepare the mud that meets on-the-spot geological conditions, there is certain weight proportion, inject in stake hole or groove and carry out retaining wall, prevent that the soil body on hole wall or cell wall from caving in.In pore-forming or grooving process, the impurity such as a large amount of grit, micro-sand that can suspend in slurry coat method, and can sinking gradually, at the bottom of forming hole or the sediment of trench bottom.If these sediments are thicker, can affect the construction quality of castinplace pile and diaphragm wall.
When measuring castinplace pile and construction of diaphragm wall at the bottom of hole or the sediment thickness of bottom land, existing measuring method is mainly to adopt chaining pin and survey cake respectively at the bottom of measured hole or the maximum submergence depth of bottom land, and difference is between the two sediment thickness.Generally, chaining pin is long reinforcing bar or weight of a 40cm, and surveying cake is that a diameter is the steel disk of 15cm.Chaining pin and survey cake and have two kinds of separate type and integral types.Compare with separate type, integral type chaining pin more easily drops on same position with surveying cake, and the sediment thickness recording 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 deep and slow slow at present, and is difficult to be inserted into sediment bottom, and the sediment thickness error recording is larger.In addition, surveyed while up promoting, this chaining pin is easily blocked and should not extract by sediment, suspension.
Through prior art literature search is found, the sediment thickness error that existing instrument records is large, be unfavorable for promoting.The weight measuring method adopting in the method > > of sediment thickness at the bottom of < < weight measured hole as Liang Qixin, twice measurement is more loaded down with trivial details, and excessive deep and slow slow at present at mud viscosity, promote also more difficultly, the sediment thickness error recording is also larger.
