摘要
The present invention is a product to be used as a structural reinforcement in the civil engineering and road construction, for use as a Buried, relates to a sewer, waste water pipes, supply and drain pipes and the like.; Generally, class-phase to be used for water pipe, sewer is a pipe which is used in an area of which the soft ground or a high load is applied is by bending the both side walls 32 of the hollow sphere (31) is formed by integration by fusing for 33 , it is being used by superposing a two-layer structure for the outer reinforcement to the real sewage pipe provided integrally to both sides of the wall 32 of the lower hollow sphere (31) (31 ') in sealing board (33).; Thus, the products, etc. a sewage pipe is soft ground or recessed area used by underground burial, so a problem in that the hollow sphere (31) 31 'parts easily broken linger, the robustness and the outer earth pressure reinforcement for this higher the inside space is required to provide the product bar, the above-described predetermined hollow sphere (31) (31 ') of each layer and bisecting a predetermined thickness is formed in a two-layer structure according to the rules, the so composed of two layers, an abutment surface 38 which is fused integrally with the lower surface in each of the hollow sphere (31) (31 ') outside the side (35 or 36) respectively sealed against outside the side (35 or 36) by bending in the direction ( but while forming a bent groove (37) that integrally to 33) constituting the joint surface (38 ') on both sides; "Hayeoseo filled with a reinforcing zone (41), the vulnerability is a hollow sphere which is exposed (31, 31, the bent grooves 26 and the joint surface 38 'and the invention to provide an outer earth pressure reinforcement and stiffness in) sites ,; In addition, this an invention of the embodiment according to, providing a reinforcement structure into and out of the side (35 or 36) integral to the reinforcing hollow sphere (42) and the support wall (49) to, in the case of long-term use by Buried part of the load or due to point load, etc., conventionally used in the hollow sphere (31) of the pipe (50) which is the vulnerability arising from the hollow section, and by providing an outer earth pressure reinforcement and rigidity a multiple tube specifications of, for standard is intended in a stable outer earth pressure reinforcement products it provides, for the invention embodiments of it.
