Description
Technical field
A kind of pile body dimensional measuring instrument is the utility model is related to, belongs to stake holes plugging technology equipment technical field.
Background technology
Because bored concrete pile can make large diameter pile, to improve bearing capacity of single pile, can be segmented again according to Internal forces state
Arrangement of reinforcement.And it is smaller to surrounding constructure influence when constructing, construction noise is also smaller, thus use is wider.But bored concrete pile is in work
Under the conditions of ground, in-site pouring pile, construction technology is complex, and it is more to influence the factor of pouring quality, easily forms various lack
Fall into and influence the integrality of pile body.According to statistics, the probability that defect occurs in in-site pouring pile driving construction pile concrete is about 15%-
20%.The comprehensive quality of bored concrete pile is embodied in following three aspect, i.e. bearing capacity, pile integrity, the durability of stake, wherein carrying
Power is difficult to accurate measurement because pile body is larger with loseless method, and when underground is without obvious Korrosionsmedium and complete pile body also not
See the report having because of durability damage.So integrality is the leading indicator of filling concrete quality of pile.In pile concrete
Defect is closely related with construction method.There is the probability occurred the defects of type of defect and different type in different construction methods
It is all different.For the reperfusion mode of concrete, bored concrete pile can be divided into underwater grouting and dry hole irrigates two classes.
For dry hole bored concrete pile, its common deficiency has following several：1）Concrete stratiform isolates or broken pile, in underground
The higher area of water level, often because having little time to drain in the swelling manhole of underground, the concrete for pouring people washes away or soaked bag, forming layer by water
Shape is isolated, and sandstone layered is accumulated when serious, and cement mortar floats, and forms broken pile；2）Local folder mud or " honeycomb " shape defect, dry hole
Perfusion because of hole wall casing seepage, gushes people's muddy water and forms local folder mud often, or does not give tamping during perfusion, forms " honeycomb " shape and lacks
Fall into；3）Local serious isolation, provided because concrete injecting height exceedes construction, often form stone and be rolled into the isolation at edge and show
As now, stone concentration zones are easily formed " honeycomb ", and mortar concentration zones are misjudged because the velocity of sound declines；4）Pile bottom sediment, operation
The non-borehole cleaning of personnel pours people's concrete, forms pile bottom sediment.
Therefore, for pile bottom sediment, need to measure hole depth in work progress and determined with the data according to hole depth
Whether non-borehole cleaning, traditional measuring method is to carry out ranging by lining rope, needs workmen hold lining rope during measurement, one side
Can not remain stable in measurement process, thus in lining rope measurement process may weak vibrations, cause ranging show and erect
It is straight relatively to jump, the measurement direction of lining rope can not be ensured when on the other hand measuring all the time straight down, measurement there may be error.
Utility model content
Therefore, the purpose of this utility model is to provide a kind of stabilization that can keep ultrasonic range finder, while can also
Enough ensure the pile body dimensional measuring instrument of the measurement direction of ultrasonic range finder all the time straight down.
To achieve these goals, a kind of pile body dimensional measuring instrument of the present utility model, including be arranged on above stake holes
Support body, plumb device is provided with the support body, ultrasonic range finder is installed on the plumb device；The plummet dress
Put including being horizontally set on the square housing on the support body, the inside casing on the inside of the housing, being installed on by bearing
First axle in the middle part of two relative edges of the inside casing, be fixed in the middle part of the two other relative edge of the inside casing and with it is described
First axle perpendicular the second axle and the 3rd axle, second axle, the 3rd axle are installed on the two of the housing by bearing respectively
On bar relative edge, in the vertical bar that is fixedly arranged in the middle of of the first axle, the vertical bar part is located at the upper of the first axle
Side, partly positioned at the lower section of the first axle, balancing weight is provided with the lower end of the vertical bar, is pacified in the balancing weight lower end
Equipped with the ultrasonic range finder.
Electromagnetic damping device is provided with the top of the vertical bar, the electromagnetic damping device includes a metallic plate, set
It is placed in the magnet on the support body and above the vertical bar.
The metallic plate is copper coin.
Using above-mentioned technical proposal, pile body dimensional measuring instrument of the present utility model, due to being provided with plummet on support body
Device, ultrasonic range finder are installed on the plumb device, and do not know directly to hold by construction worker, therefore are used
When vertical bar can be made to freely swing, final vertical bar keeps vertical state in the presence of balancing weight, so as to keep ultrasonic wave
The measurement direction of rangefinder is all the time straight down, additionally it is possible to keeps stabilization of the ultrasonic range finder in measurement process；By surveying
Need to wait the swing of vertical bar to stop before amount, therefore be further provided with plumb device and be made up of copper coin and magnet again
Electromagnetic damping device, then relatively rapid vertical bar can be made to stop swinging before measuring.Pile body length of the present utility model
Survey tool is spent, it is simple in construction, convenient operation, the stabilization of ultrasonic range finder can be kept, while can also ensure that ultrasonic wave
The measurement direction of rangefinder straight down, greatly improves measurement accuracy all the time.
