Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The utility model provides a bored concrete pile sediment thickness detection device, as shown in fig. 1-3, this bored concrete pile sediment thickness detection device includes: the device comprises a pressing sinking block 1, a round pipe 2 connected to the bottom of the pressing sinking block, a plurality of buckles 3 arranged on the side wall of the round pipe and a clamping plate 4 movably sleeved on the round pipe.
The plurality of snaps 3 are made of an elastic material, and particularly, the snaps 3 are made of a rubber or resin material.
Through above-mentioned scheme, rubber or resin material deformability is stronger, and loses easily under the condition of external force oppression and resume the stake, can improve bored concrete pile sediment thickness detection device's life.
Sinking the briquetting 1 and being made by solid stainless steel, stainless steel material quality is big, can increase the device dead weight on the one hand for the device can overcome the buckle that elastic material made and the resistance of sediment and continue to descend passing pile foundation sediment decline in-process, makes bored concrete pile sediment thickness detection device's measuring result more reliable, and on the other hand device testing process can inevitably contact water, uses stainless steel material can improve the life of device.
Through above-mentioned scheme, when equidistance set up and make cardboard 4 and buckle 3 contact, the resistance that cardboard 4 moved can be reduced in the setting of fan-shaped limit cambered surface, and the cardboard 4 of being convenient for moves about between the bayonet socket.
Referring to fig. 2, the circular tube 2 is an incomplete circular tube, in this embodiment, a parallel opening is formed in the side surface of the circular tube 2, and the circular tube notch 5 far away from the sinking block 1 is set to be in a cutter shape (the end surface is sharp). In addition, set up logical groove 6 that has 2 section shapes of rain pipe to match on cardboard 4 (set up non-cylinder logical groove on the cardboard), both be incomplete ring shape, the inner ring diameter of ring is less than 2 internal diameters of pipe, the outer loop diameter of ring is greater than 2 external diameters of pipe and is less than 2 sum of pipe 2 plus cardboard right-angle side length of a side, therefore cardboard 4 accessible logical groove slides on pipe 2.
Through the scheme, the round pipe 2 is arranged into the incomplete shape so as to increase the action area of the clamping plate 4 (increase the action area of the clamping plate 4 and the sediment surface), the descending resistance of the clamping plate 4 can be increased due to the increase of the area, and the phenomenon that the measuring precision of the thickness of the pile foundation sediment is influenced by the continuous descending of the round pipe 2 due to the fact that the resistance is insufficient due to the fact that the clamping plate 4 is too small in contact surface with the sediment after contacting the sediment surface is prevented; the provision of the cut-outs 5 allows for easier insertion of the device into the sediment than would be possible with a sharp cut-out 5, given that sediment generally contains a large amount of grit deposits.
And set up the logical groove 6 that matches with the pipe shape on the cardboard 4, can be spacing with cardboard 4, fix between adjacent cardboard, receive the sediment at cardboard 4 and produce ascending effort, cardboard 4 stops can not continue downstream on the hole bottom sediment surface, and the resistance of buckle 3 that the briquetting 1 drives pipe 2 and overcome elastic material and make under the dead weight influence continues to descend with the sediment.
In addition, the first and second substrates are,
as shown in fig. 1, the top of the sinking-pressing block 1 is connected with a cylinder, and the cylinder is provided with a hanging hole 11.
Through the scheme, the device can be hung on the crane by using the lifting rope and slowly placed into the hole at a constant speed for detection.
Referring to fig. 4, the card 3 is provided in a square shape.
A row of sand holes 7 are formed in the center of the clamping plate 4, and the diameter of each sand hole 7 is smaller than that of the through groove 6.
Through above-mentioned scheme, consider that cardboard 4 descends the in-process, the grit precipitate can block up the clearance between pipe inner wall and cardboard 4 and make cardboard 4 can't move on pipe 2 smoothly to can't obtain accurate sediment thickness, set up row's sand hole 7 at cardboard 4 center and can effectively prevent this type of condition, the grit then can be followed and discharged in the opening of pipe 2, increases the measurement precision.
And scale marks are arranged in the length direction of the circular tube 2.
Through above-mentioned scheme, the distance between 5 to the cardboard 4 of incision directly reads through the setting slogan of scale mark, is convenient for learn pile foundation sediment thickness.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
