Detailed Description
The utility model is described in detail below with reference to the attached drawing figures: the advantages and features of the present utility model will become more apparent from the following description. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.
Referring to fig. 1 to 2, an embodiment of the present utility model provides a self-balancing detection device 100 suitable for a post-grouting process of a small-diameter pile foundation, which includes a self-balancing load box 110 and a grouting mechanism 120, wherein:
the self-balancing load box 110 has a diameter less than or equal to the diameter of the small diameter pile foundation.
Grouting mechanism 120 is disposed on the self-balancing load box 110.
Wherein grouting mechanism 120 comprises:
the sleeve 122 is vertically disposed thereon by opening a hole in the self-balancing load box 110.
An upper grouting pipe 121 is communicated with the upper part of the sleeve 122 and extends out of the upper surface of the self-balancing load box 110. Wherein the upper grouting pipe 121 and the sleeve 122 can be screwed.
A lower grouting pipe 123 is communicated below the sleeve 122 and extends out of the lower surface of the self-balancing load box 110. Wherein the down tube 123 and the sleeve 122 may be threadably coupled.
