Outer protective cover is constituted, and the protective cover is made up of elastomeric material, and the left surface of the interior protective cover is arcwall face, the interior protective cover
Right output port be that the hole wall of placement force sensor on cannelure and drilling rod matches, the outer protective cover is and putting on drilling rod
Put the plate that the drilling rod surface outside the aperture of pressure transducer is affixed；The upper end of baffle plate is to obtain with the placement force sensor on drilling rod
The groove that emptying aperture wall matches, plate of the baffle plate in upper end relative superiority or inferiority end low dip keep off interior protective cover in lower section, by screw by pressure
Sensor holder, baffle plate and inside and outside protective cover are fixed on the hole wall of the sensor on drilling rod.Pressure transducer is located at the drilling rod
In the hole on drilling rod wall above lower end, the position in the hole on the drilling rod wall is determined according to following conditions, and drilling rod lower end is to brill
The distance in the hole on bar wall is that the volume in the drilling rod hole between the hole on drilling rod lower end to drilling rod hole wall is dirty with design requirement
The volume of grease head highness is equal, and the pressure transducer is wireless pressure sensor, and it is left that the pressure transducer is placed in sensor holder
In the groove of side, this sensor holder is relative with the pressure transducer hole on drilling rod wall, and the pressure in the sensor holder and its groove is passed
Sensor is placed in protective cover, and the protective cover is constituted for inside and outside protective cover, and the protective cover is made up of elastomeric material, described interior
The left surface of protective cover is arcwall face, and the right output port of the interior protective cover is that cannelure is matched with drilling rod hole wall, the outer protective cover
It is plate that the drilling rod surface outside the aperture with placement force sensor is affixed；The upper end of baffle plate is to match with the hole wall on drilling rod wall
Groove, plate of the baffle plate in upper end relative superiority or inferiority end low dip keep off interior protective cover in lower section, by screw by sensor holder, baffle plate and
Inside and outside protective cover is fixed on the hole wall of the sensor of drilling rod.
There is this utility model discovery drilling rod valve in time to be not switched on and ensure the aobvious of pile crown height compared with the prior art
Write advantage.
Description of the drawings：
Fig. 1 is this utility model building jackrod structure schematic diagram；Fig. 2 is close-up schematic view at Fig. 1 I.
Specific embodiment：
The technical solution of the utility model as shown in Figure 1-2, in order to be able to find in time the valve on 1 termination of drilling rod not beat
Open state, arranges a pressure transducer 1, the pressure transducer on the drilling rod wall at the top 30cm or 0.5m of drilling rod termination
One, it is wireless senser, in order to prevent concrete damage pressure transducer, pressure transducer is fixed on sensor holder 5
In groove, the sensor holder is placed in the protective cover by made by elastomeric material, and the protective cover is made up of inside and outside protective cover 6,7, should
The right output port of interior protective cover is provided with the cannelure with the hole wall matching of the placement force sensor on building drilling rod, the interior protective cover
Left side be arcwall face, the arcwall face not with pressure sensor contacts, the outer protective cover is and placement force on drilling rod is passed
The plate that drilling rod surface outside the aperture of sensor is affixed, in order to avoid when concrete material is injected to drilling rod to the damage of protective cover with
And make pressure transducer send rub-out signal, and baffle plate 8 is set, the upper end of the baffle plate is and the placement force sensor on drilling rod
The groove that hole wall matches, plate of the baffle plate in upper end relative superiority or inferiority end low dip, the groove on baffle plate is enclosed within the upper end of drilling rod hole wall first
After being screwed, then on the pressure transducer hole wall that the cannelure on the right side of interior protective cover is sheathed on drilling rod after, will set
After the sensor holder for having pressure transducer 1 is placed on the left of interior protective cover in arcuate groove, outer protective cover is covered in into drilling rod sensor
On drilling rod wall outside putting hole and it is screwed.
In order to ensure the design height of pile crown, pressure transducer 23, the pressure transducer two are set on building drilling rod
Have and the inside and outside pressure transducer protective cover of one identical of pressure transducer, pressure transducer seat and baffle plate, the pressure transducer two
Method for determining position is, the distance between drilling rod lower end to pressure transducer two, the volume of concrete in drilling rod hole,
Should be identical with the volume of the pile crown height of design.According to the aperture of design height and drilling rod into dirty aperture and dirty head, just
Can determine that the distance of pressure transducer two and drill bit lower end.Drilling rod, valve and screw blade 2 are without modification.
Operation principle of the present utility model and operational approach, the length of drilling rod are fixed, depth according to the dirty hole of design requirement,
Dirty grease head highness, operator stop drilling, inject concrete material, work as coagulation into drilling rod hole when drilling rod gets into projected depth
Soil is raised to pressure transducer for the moment in drilling rod hole, and concrete extrusion protective cover is contacted with pressure transducer one, this pressure sensing
Device one send signal green indicating lamp it is bright when, stop material feeding, start lifted drilling rod, concrete material enter dirty hole and not with protective cover
Contact, green indicating lamp are extinguished, and illustrate that drilling rod lower end valve is opened, if it is indicated that lamp does not extinguish, illustrate that valve is not switched on, should
Processed, as pressure transducer one is near away from drilling rod lower end distance, process is easier.
Under valve open mode, be lifted up drilling rod while concrete is injected to drilling rod hole, when drilling rod lower end rises
To the upper end of pile（The lower end of pile crown）When, can mark be set on drilling rod in advance, when the corresponding positions of the mark to rig, be stopped
Drilling rod is only lifted, makes the concrete material in drilling rod hole be raised to pressure transducer two, when red led is bright, stop material feeding, now
Material in drilling rod hole just forms the height of the dirty head of design requirement.Avoid the pile crown error for manually controlling by rule of thumb to cause big
Scarce limit.
