In an exemplary embodiment, cylindrical elastic casing 202 may also prevent grout penetration from the outer space of conical-head pipe 102 into inner chamber 1222 of hollow rod 122 through thorough injection hole 1226. In an exemplary embodiment, when cylindrical elastic casing 202 completely covers thorough injection hole 1226, grout may be prevented from penetration into inner chamber 1222 of hollow rod 122 through thorough injection hole 1226 due to the fact that cylindrical elastic casing 202 may block thorough injection hole 1226. In an exemplary embodiment, when conical-head pipe 102 is inserted to the ground, grout may be pumped into inner chamber 1222 of hollow rod 122 to fill a created well around conical-head pipe 102. In an exemplary embodiment, the pumped grout may be discharged from inner chamber 1222 of hollow rod 122 through thorough injection hole 1226. In an exemplary embodiment, it may be understood that due to the deformability and flexibility of cylindrical elastic casing 202, cylindrical elastic casing 202 may be deformed against a pressure of the pumped grout and, thereby, thorough injection hole 1226 may be unblocked and allow the pumped grout to discharge from inner chamber 1222 of hollow rod 122. Furthermore, cylindrical elastic casing 202 may prevent the grout from returning into inner chamber 1222 of hollow rod 122 through thorough injection hole 1226. In an exemplary embodiment, cylindrical elastic casing 202 may be made up of a flexible elastic. In an exemplary embodiment, the flexibility of cylindrical elastic casing 202 may provide a facility for cylindrical elastic casing 202 that allow grout to discharge from inner chamber 1222 of hollow rod 122 through thorough injection hole 1226 but does not allow the grout to return to inner chamber 1222 of hollow rod 122. In an exemplary embodiment, it may be understood that cylindrical elastic casing 202 may act as a check valve that may allow grout to discharge from inner chamber 1222 of hollow rod 122 through thorough injection hole 1226 but does not allow the grout to return to inner chamber 1222 of hollow rod 122.

That scope is intended and should be interpreted to be as broad as is consistent with the ordinary meaning of the language that is used in the claims when interpreted in light of this specification and the prosecution history that follows and to encompass all structural and functional equivalents. Notwithstanding, none of the claims are intended to embrace subject matter that fails to satisfy the requirement of Sections 101, 102, or 103 of the Patent Act, nor should they be interpreted in such a way. Any unintended embracement of such subject matter is hereby disclaimed.

(38) Except as stated immediately above, nothing that has been stated or illustrated is intended or should be interpreted to cause a dedication of any component, step, feature, object, benefit, advantage, or equivalent to the public, regardless of whether it is or is not recited in the claims.

(39) It will be understood that the terms and expressions used herein have the ordinary meaning as is accorded to such terms and expressions with respect to their corresponding respective spaces of inquiry and study except where specific meanings have otherwise been set forth herein. Relational terms such as first and second and the like may be used solely to distinguish one entity or action from another without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “a” or “an” does not, without further constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

(40) The Abstract of the Disclosure is provided to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in various implementations. This is for purposes of streamlining the disclosure, and is not to be interpreted as reflecting an intention that the claimed implementations require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed implementation. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separately claimed subject matter.

(41) While various implementations have been described, the description is intended to be exemplary, rather than limiting and it will be apparent to those of ordinary skill in the art that many more implementations and implementations are possible that are within the scope of the implementations. Although many possible combinations of features are shown in the accompanying figures and discussed in this detailed description, many other combinations of the disclosed features are possible. Any feature of any implementation may be used in combination with or substituted for any other feature or element in any other implementation unless specifically restricted. Therefore, it will be understood that any of the features shown and/or discussed in the present disclosure may be implemented together in any suitable combination. Accordingly, the implementations are not to be restricted except in light of the attached claims and their equivalents. Also, various modifications and changes may be made within the scope of the attached claims.
