Aiming at the defects in the prior art, the utility model provides a precast concrete underground water delivery pipe.
A precast concrete underground water delivery pipe comprises a U-shaped pipe wall precast by ultra-high performance concrete, wherein a U-shaped upper plate groove precast by the ultra-high performance concrete is arranged at the top of the opening side of the pipe wall, and the upper plate groove and the pipe wall are detachably connected or integrally formed; common concrete or muck is poured into the grooves of the upper plate groove to form a top plate; and stiffening ribs are arranged between the included angles between the upper plate grooves and the pipe wall and are integrally formed with the pipe wall.
When the upper plate groove is detachably connected with the pipe wall, the stiffening ribs are pre-embedded with pre-embedded bolts, and pre-embedded bolt holes are correspondingly formed in the upper plate groove.
The embedded bolts are arranged in a plurality along the length direction of the pipe wall.
The width of the pipe wall is larger than that of the upper plate groove.
When the upper plate groove and the pipe wall are integrally formed, the width of the upper plate groove is consistent with that of the pipe wall.
The utility model has the beneficial effects that: the utility model provides a precast Concrete underground water pipe which is manufactured by adopting Ultra-High Performance Concrete (Ultra-High Performance Concrete) by comprehensively considering the problems in the use of municipal water pipes and the development of the current building materials. According to the actual engineering condition, the water conveying pipes with different sizes can be manufactured, when the engineering with larger water conveying quantity is needed, the water conveying pipes can be prefabricated in blocks, and the pipes with smaller conveying quantity can be integrally prefabricated. The compressive strength of the ultra-high performance concrete can reach more than 3 times of that of common concrete, the flexural strength of the ultra-high performance concrete is more than 10 times of that of the common concrete, the elastic modulus of the ultra-high performance concrete is more than 1.2 times of that of the common concrete, and the ultra-long durability of the ultra-high performance concrete can reach more than 200 years.
