Embodiment 1

[0038] Embodiment 1: a kind of rainwater pipe embedding structure, such as figure 1 As shown, the revetment 1 is included, and the side of the revetment 1 facing the water is provided with two circles of cofferdams 4 . Such as figure 2 As shown, two circles of cofferdams 4 are arranged concentrically, and each circle of cofferdams 4 includes a concrete body 5, and steel pipes 6 are arranged on the side of the concrete body 5 to increase the strength.

[0039] Such as figure 1 As shown, the revetment 1 includes a wall 1-1 arranged perpendicular to the ground, and a front toe 1-2 is set on the side of the wall 1-1 facing the water, and the front toe 1-2 is connected to the cofferdam 4 through a concrete foundation 7 . The concrete foundation 7 is connected to the ground through an earthwork group 8 . The ground is inclined, and the height gradually decreases from wall 1-1 to cofferdam 4. The first excavation groove 9 that is concave on the inclined ground is dug on the gro...

Embodiment 2

[0044] Embodiment 2: a kind of rainwater pipe embedding method, comprises the steps:

[0045] First, the prefabricated square pile 3 is driven into the side of the body of wall 1-1 facing the water area, and the side of the body of wall 1-1 facing the water area is set as an inclined plane. The inclined structure of the inclined plane is: the top of the body of wall 1-1 faces the water area The projection of one end in the vertical direction falls on the cross-sectional area of ​​the bottom of the wall body 1-1. The side facing the waters at the bottom of the body of wall 1-1 is the front toe 1-2, and the prefabricated square pile 3 is vertically driven into the ground on the side of the front toe 1-2 facing the waters, the overall length of the prefabricated square pile 3 It is 7m, the elevation of the end driven into the ground is -4.40m, and the elevation of the end exposed to the ground is 2.293m.

[0046] Among the prefabricated square piles 3, the prefabricated square p...

Abstract

The invention discloses a rainwater pipe embedding method. According to the technical scheme, a rainwater pipe embedding structure comprises a bank revetment, and a rainwater pipe is arranged in the bank revetment. The rainwater pipe embedding structure is characterized in that the bank revetment comprises a wall body, and a foretoe located on the side, facing a water area, of the wall body, a prefabricated square pile is arranged on the side, near the water area, of the foretoe, a cofferdam is arranged around the wall body to isolate the wall body and the prefabricated square pile from the water area, the cofferdam comprises a concrete body and a steel pipe vertically penetrating through the concrete body, and the wall body is connected with the cofferdam through a concrete foundation. In this way, after the cofferdam is arranged, the cofferdam isolates water flow in the water area outside so as to leave room for construction. The cofferdam, the concrete foundation and the wall body form an integral body. After being impacted by water flow and ship waves, the construction structure with the concrete foundation is more stable and less prone to damage than an independently arranged cofferdam.

Description

technical field [0001] The invention relates to the field of water conservancy engineering port protection structures, in particular to a rainwater pipe embedding structure and method thereof. Background technique [0002] The rainwater pipe is a water conservancy structure buried in the revetment to facilitate the introduction of rainwater and other fluids into rivers and other waters. [0003] At present, the Chinese patent with the publication number CN102113607A discloses a rainwater pipe structure and its construction method. The structure of this rainwater pipe is: firstly prefabricate the rainwater pipe, connect the adjacent rainwater pipe joints end to end, and set a prefabricated rainwater pipe joint at the bottom of the rainwater pipe joint. production, the prefabricated support is provided with an arc-shaped contact surface, and the contact surface between the prefabricated support and the prefabricated rainwater pipe joint is provided with cement mortar. In the ...
