Description of the embodiments
For a more visual and complete understanding of the technical solution of the utility model, non-limiting features will now be described with reference to the accompanying drawings, in which:
As shown in fig. 1-3, the grouting expansion nail comprises a main pipe body 1 with a through middle part, wherein a threaded passage 104 is formed in the inner wall of the tail section of the main pipe body 1, the tail of the main pipe body 1 is in threaded connection with a secondary pipe body 5, the head of the secondary pipe body 5 is a threaded rod 501 in threaded fit with the threaded passage 104 of the main pipe body 1, and an elastic body 3 and an opening support 4 are longitudinally sleeved outside the secondary pipe body 5 in sequence from the tail end position of the main pipe body 1; the diameter of the tail part of the auxiliary pipe body 5 is increased, a slope 502 for supporting the supporting piece 4 is arranged at the position of changing the small diameter into the large diameter, a through runner is arranged in the middle of the auxiliary pipe body 5, a horn mouth 504 is arranged at the tail part of the runner, one end with a large caliber of the horn mouth 504 faces the tail end of the auxiliary pipe body 5, one end with a small caliber of the horn mouth 504 is abutted to a plug 6, the other end of the plug 6 is abutted to a spring 7, and the tail end of the spring 7 is fixed at the tail part of the horn mouth 504.
The middle part of the opening support piece 4 is also penetrated and inserted with the auxiliary pipe body 5, the tail part of the opening support piece 4 is provided with support grooves 401 which are communicated with the hollow structure of the opening support piece and extend towards the outer wall direction of the opening support piece 4, the number of the support grooves 401 is generally four on average, and the purpose is to play a partition role and also to thin the inner wall of the opening support piece 4, so that the opening difficulty is reduced. The general opening support 4 can be designed to be made of plastic materials so as to reduce the production cost.
The tail end of the main body pipe is provided with an annular base 103, so that the contact area between the tail and other parts is increased.
A gasket 2 is arranged between the base 103 and the elastic body 3, and the gasket 2 plays a role in average stress.
The elastomer 3 is the rubber material, and the design of the rubber material of elastomer 3 is favorable to the atress even, and on the other hand plays some inflation buckle effect, and the buckle effect of this time is limited certainly, also has certain outside sealed effect this time.
The plug 6 is a rubber ball or a metal ball, the plug 6 mainly plays a role of blocking a flow passage, and is in a blocking state under the normal condition by matching with the acting force of the spring 7; when an external force is applied, for example, the grouting machine performs grouting through the main body pipe, because the external pressure increases to enable the plug 6 to downwards open the flow passage, the spring 7 is usually a pagoda spring 7, and the tail of the spring 7 is fixed at the protruding position (the protruding position is not shown in the figure) of the tail of the bell mouth 504, namely, the spring acts as a one-way valve.
