Technical field
The present invention relates to urban infrastructure construction field, and in particular to a kind of lower embedding type concrete component intensity it is non-
Excavate detection device and its method.
Background technology
Lower embedding type concrete structure, mainly includes Underground Culvert, underground conservation pool etc..These concrete structures are long-term
Under harsh environment in a variety of physics, chemistry and biological corrosion source, weathering Erosion easily gradually occurs for concrete, so as to reduce
The intensity of concrete, it is therefore necessary to be periodically detected to the intensity of lower embedding type concrete structure.
At present, when carrying out the detection of lower embedding type concrete component intensity, it is common practice that plate top earthing large area is opened
Dig, testing staff carries out intensity detection work on the exposed concrete slab surface of large area.Need to backfill after test, it is time-consuming, take
It is power, of high cost, while can also have a degree of destruction to urban environment.
The content of the invention
It is an object of the invention to provide device and the side that a kind of lower embedding type concrete component intensity carries out Indirect testing
Method, while reaching testing goal, mitigates the labor intensity of intensity detection work, destruction when mitigating detection to ecological environment.
The present invention takes following technical scheme:

Casing 7, reisilometer 1, fixture 2;The support rod bush 7 is sleeved on outside supporting rod 10, and support rod bush 7 is laterally across fixture 2
It is fixedly connected with reisilometer 1, reisilometer 1 is arranged in parallel with support rod bush 7;Spring 11, which is arranged, to be installed on outside supporting rod 10,
And positioned at the lower section of fixture 2;Support rod bush 7 can drive 1 around rod of reisilometer to rotate, and radius of turn is less than from ground to mixed
The radius of the instrument connection of solidifying soil component.
Further, foot stool 9 is further included, the foot stool is fixed on outside support rod bush 7, and is supported on level ground
On.
Further, handle 8 is also fixedly installed outside the support rod bush 7.
Further, guide sleeve 5 is further included, the guide sleeve 5 is fixed on outside support rod bush 7, reisilometer 1
On its interior, 5 outside diameter of guide sleeve is equal to or slightly less than the open pore size that concrete surface is buried on ground under.
Further, dial 6 is also arranged outside the support rod bush 7,6 outside diameter of dial is more than guide sleeve
5, and the upper end that the perforate of concrete surface is buried on ground under can be covered in.
Further, 5 bottom of guide sleeve is equipped with antipriming 12.
Further, the fixture 2 is connected by nut 3 and a pair of of screw rod 4 with support rod bush 7,3 energy of rotating nut
Enough adjust the rotating radius of 1 around rod of reisilometer.
A kind of application method of the Indirect testing device of above-mentioned lower embedding type concrete component intensity, including following step
Suddenly:
S1, form circular hole on the ground, until lower embedding type concrete component upper surface;
The lower embedding type concrete component intensity Indirect testing device, be inserted into the circular hole by S2;
S3, overcome 11 elastic force of spring to press down on handle 8, and reisilometer 1 carries out intensity detection;
S4, the position by rotating the support change fixture 2 of rod bush 7 and/or the spacing for changing fixture 2 and supporting rod 10
Measure multiple measuring points.
Further, in step S4, the quantity of the measuring point is at least 16.
Further, in institute step S4, the reisilometer 1 detects the functional unit of data or with biography with storage
The functional unit of defeated detection data.
The beneficial effects of the present invention are:
1) lower embedding type concrete component intensity Indirect testing device in implementation process only need to soil body part pore-forming,
Detection is simple, is excavated without large area, to avoid detection risk and can reduce engineering cost, while to the influence of ecological environment
It is smaller;
2) detection hole can retain, and repeatedly use, and recover original appearance without earthing, be conducive to long-time periodic detection,
Further reduce the workload of detection;

Embodiment
The present invention is further described with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1-Fig. 3, a kind of lower embedding type concrete component intensity Indirect testing device, including supporting rod 10, spring
11st, rod bush 7, reisilometer 1, fixture 2 are supported;The support rod bush 7 is sleeved on outside supporting rod 10, and support rod bush 7 is laterally
It is fixedly connected by fixture 2 with reisilometer 1, reisilometer 1 is arranged in parallel with support rod bush 7;Spring 11, which is arranged, is installed on support
Outside bar 10, and positioned at the lower section of fixture 2;Support rod bush 7 can drive 1 around rod of reisilometer to rotate, and radius of turn is less than
From ground to the aperture of the circular hole of concrete component.
Referring to Fig. 1-Fig. 2, foot stool 9 is further included, the foot stool is fixed on outside support rod bush 7, and is supported on flatly
On face.
Referring to Fig. 1-Fig. 2, handle 8 is also fixedly installed outside the support rod bush 7.
Referring to Fig. 2, guide sleeve 5 is further included, the guide sleeve 5 is fixed on outside support rod bush 7, reisilometer 1
Portion in the inner, 5 outside diameter of guide sleeve are equal to or slightly less than the open pore size that concrete surface is buried on ground under.
Referring to Fig. 2, dial 6 is also arranged outside the support rod bush 7,6 outside diameter of dial is more than guide sleeve 5, and
The upper end that the perforate of concrete surface is buried on ground under can be covered in.
Referring to Fig. 2,5 bottom of guide sleeve is equipped with antipriming 12.
Referring to Fig. 3, the fixture 2 is connected by nut 3 and a pair of of screw rod 4 with support rod bush 7, and rotating nut 3 can
Adjust the rotating radius of 1 around rod of reisilometer.
Reisilometer 1 is digital display integral reisilometer.
When it is implemented, it is divided into following steps:
Step 1:An aperture is drilled out or dug out on the ground using microdrill or Luoyang Spade;
Step 2:Guide sleeve 5 is inserted into aperture, sleeve bottom is provided with antipriming 12, and and concrete component
Intimate surface contact;
Step 3:Unnecessary soil and water in casing are removed, keeps the smooth drying of surface of concrete structure;
Step 4:Digital display integral reisilometer 1 is fixed on control device, and makes the spacing of the two minimum, is then reached
5 bottom of guide sleeve so that supporting rod 10 is placed on concrete component, and on the center of circle of casing 5;
Step 5:Support rod bush 7 is rotated by control handle 8 and angularly plays 8 rebounds;
Step 6:Measuring instrument is entirely proposed from hole, between adjustment digital display integral reisilometer 1 and control device
Away from so that the spacing of the two is maximum, then stretches into again in hole, copies step 5 to continue to play 8 rebounds;
Step 7:By 16 rebound values measured, according to the concrete strength in proper calculation concrete survey area.
The present invention is in implementation process without lower embedding type concrete component earthing is all excavated, it is only necessary to soil body office
Portion's pore-forming, detection is simple, saves substantial amounts of manpower and financial resources.The protection of ecological environment is also beneficial at the same time.The detection of formation
Hole is after one-time detection, ordinary circumstance, it is not necessary to is backfilled, a pipe cap need to be only added on casing, can be repeated several times makes
With convenient periodically progress concrete strength inspection.
Above is the preferred embodiment of the present invention, those of ordinary skill in the art can also carry out various on this basis
Conversion improves, and on the premise of the total design of the present invention is not departed from, these conversion or improvement should all belong to application claims
Within the scope of protection.
