Abstract
The utility model discloses an embedding device for a pore water pressure gauge. The embedding device comprises a cavity cone, wherein the top of the cavity cone is connected with the lower end of a connecting steel tube; the upper end of the connecting steel tube is connected with the lower end of a hollow drill rod; an opening is formed in the side wall of the cavity cone; a closing door is arranged on the opening and is hinged to the cavity cone. According to the embedding device disclosed by the utility model, the pore water pressure gauge is carried by the cavity cone with the side opening and the closing door; single-hole and single embedding of the pore water pressure gauge is realized by adopting a mode of pressing by the hollow drill rod, so that the difficult problem that pore water pressure gauges are embedded in strings to cause the blockage is solved. In addition, by adopting the cavity cone, side resistance of a soil body in the embedding process can be reduced, the pressing-in of the drill rod is facilitated and the embedding efficiency can be increased. Meanwhile, the embedding device disclosed by the utility model has the characteristics of simple structure and convenience in use.
Description
Technical field
The utility model relates to underground monitoring pore water pressure technical field, particularly a kind of embedded device of pore pressure gauge.
Background technology
At present, pore water pressure test is a kind of method of testing comparatively conventional during reinforced soft soil ground is processed.In test,, there is shrinkage cavity or cave in conventionally need to follow up sleeve pipe or carry out mud off of the method for embedding of pore pressure gauge avoiding in pore forming process.Especially the super soft ground high for water content, void ratio is large, the soil body is often moulded or soft-plastic state in stream, and the quality of pore-forming and shutoff is directly connected to the quality of burying underground of pore pressure gauge.Mainly there is the problem of the following aspects in the method for embedding of current routine: 1), though pore pressure gauge can be buried underground by disposable bunchiness, the shutoff difficulty between upper and lower pore pressure gauge, easily causes pore water to gang up up and down, test data distortion.2) carry out sleeve pipe and mud off complex process, cost is higher.
At present, there is a kind of deep embedding device for pore pressure gauge, can solve the problem such as severity control and the even transmission of pore water pressure in Embedded Installation of Pore Water Pressure Gauge.But the complex structure of this device, buries cost underground relatively high, and pore pressure gauge connects up and down, and shutoff problem is difficult to effective solution, especially for soft foundation under water.
Summary of the invention
The utility model provides a kind of embedded device of pore pressure gauge for solving the technical problem existing in known technology, this device can overcome pore pressure gauge bunchiness buries the difficult problem of shutoff underground.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: a kind of embedded device of pore pressure gauge, comprise cavity cone, the top of described cavity cone is connected with the lower end of a joint steel pipe, and the upper end of described joint steel pipe is connected with the lower end of a hollow drill; On the sidewall of described cavity cone, be provided with opening, described opening is provided with closing door, and described closing door is hinged in described cavity cone.
The upper end of described joint steel pipe and the lower end of described hollow drill are threaded connection.
Advantage and the good effect that the utlity model has are: carry pore pressure gauge by employing with the cavity cone of side opening and closing door, and the mode that adopts hollow drill to press down, pore pressure gauge is carried out to single hole list and bury, avoided pore pressure gauge bunchiness to bury the shutoff difficult problem running into underground.And adopt cavity cone, can reduce to bury underground the lateral resistance of the soil body in process, be convenient to drilling rod and be pressed into, can improve and bury efficiency underground.Meanwhile, the utility model also has feature simple in structure, easy to use.

Detailed description of the invention
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1～Fig. 4, a kind of embedded device of pore pressure gauge, comprises cavity cone 1, and the top of described cavity cone 1 is connected with the lower end of a joint steel pipe 5, and the upper end of described joint steel pipe 5 is connected with the lower end of a hollow drill 7; On the sidewall of described cavity cone 1, be provided with opening 4, described opening 4 is provided with closing door 2, and described closing door 2 is hinged in described cavity cone 1 by hinge 3.
In the present embodiment, be provided with screw thread 6 in the upper end of described joint steel pipe 5, the lower end of the upper end of described joint steel pipe 5 and described hollow drill 7 is threaded connection.
Refer to Fig. 4, when use, pore pressure gauge 8 is put into cavity cone 1 by opening 4, closing door with radian 2 is closed on opening 4, hollow drill 7 is connected with joint steel pipe 5, then hollow drill is pressed in soil, owing to being subject to the squeezing action of the soil body, closing door 2 is closure state pressing down in process, when hollow drill is pressed into after desired depth, slowly, carry hollow drill, closing door 2 is automatically opened under the Action of Gravity Field of himself, and pore pressure gauge 8 falls into the soil body of desired depth; To its blast around, wrap pore pressure gauge 8 by hollow drill, so far completed burying underground of a pore pressure gauge 8.The mode that said apparatus adopts single hole list to bury to pore pressure gauge, overcome pore pressure gauge and buried the shutoff difficult problem causing underground because of bunchiness, and simple and light, adopt cavity cone structure, reduce to bury underground the soil body lateral resistance in process, be convenient to drilling rod and be pressed into.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, can also make a lot of forms, within these all belong to protection domain of the present utility model.
