Along with the reinforcing of environmental protection, in addition the water resource is more and more precious, in order to the various water resources of utilization that can be better, municipal administration rain sewage diversion pipeline emerges in each city.

Due to the immaturity of construction technology, the construction of the rain and sewage pipeline cross joint is always a big difficulty. At present, the existing construction technology is a construction method mentioned in the text of 'example exploring municipal drainage pipeline groove-closing construction and steel sheet pile support technology' issued in Fujian building materials by forest development: when the rainwater main line and the sewage branch line are crossed, the rainwater main line is constructed firstly, when a sewage pipeline is installed, the constructed rainwater main line can be supported by bricking firstly, then soil is drawn from the lower side of the rainwater main pipe to penetrate the pipe, a 180-degree concrete pipe seat is adopted, and after the sewage branch line is installed, concrete is poured into a groove of the bricking support to the base of the rainwater pipeline.

In order to solve the problems of the construction technology, it is very important to design a rainwater and sewage pipeline intersection node with high construction efficiency and good construction effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming not enough among the prior art, providing a rain sewage pipeline alternately node.

The rainwater and sewage pipeline cross joint comprises a rainwater pipe fixing and protecting hanger, a soil digging and supporting pipe penetrating mold, a rainwater pipe, a sewage pipe, a precast concrete support and a hoop; the rainwater pipe fixing and protecting hanger comprises a support frame, a connecting rod and a profile steel groove, wherein the rainwater pipe is placed in the profile steel groove with the size matched with that of the rainwater pipe, and the profile steel groove is fixed with the support frame through the connecting rod; the soil digging and supporting pipe penetrating die is a block die with a circular pipe penetrating opening; cement mortar is injected between the sewage pipe and the surrounding filling soil; the anchor ear is pre-buried in the precast concrete support, and the sewage pipe passes through the anchor ear with precast concrete support is fixed together, and the anchor ear passes through the bolt and is fixed with the nut.

Preferably, the method comprises the following steps: the soil digging support pipe penetrating die is made of concrete materials.

The utility model has the advantages that:

(1) the utility model provides a rainwater pipeline that the construction was accomplished can be fixed to the fixed protection gallows of rainwater pipe, can prevent moreover that the rainwater pipeline that the construction was accomplished from receiving the effect of factors such as external force, has good technical benefit.

(2) The utility model provides a draw native support poling mould can provide for the rainwater line of construction completion and strut, for drawing native poling under the rainwater pipe and providing the construction space, the mould structure is fairly simple moreover, easily preparation.

(3) The utility model provides a prefabricated assembled support and synchronous poling of sewage pipe have reduced the cast-in-place operation volume of concrete, and have reduced the construction procedure, and technical benefit is showing.
