The pipeline is ensured to be stably fixed on the premise of simple and convenient installation.
The installation and use method of the rainwater pipeline comprises the following steps:
1. a rapid positioning sleeper beam of a prefabricated rainwater pipe is disclosed. The mould is designed according to the standard size of the sleeper beam. And manufacturing the positioning sleeper beam according to the designed standard size and the mould. Taking DN2000 second-level reinforced concrete plain end pipe as an example, the length of the component is 1550mm, the width of the component is 500mm, the groove excavation width is 4800mm, and 100mm is reserved in the middle of the two components, so that the components can be conveniently installed and corrected. The thickness of the base of the component is 400mm, and the stable part is 600mm higher than the top of the base. And (5) transporting the prefabricated sleeper beam to a construction site after the strength of the prefabricated sleeper beam meets the requirement.
2. Rainwater pipe groove excavation
Before the rainwater pipe digs the groove, should carry out the rainwater pipe well stake laying-out comprehensively to the plane position and the trend of giving out the rainwater pipe excavation, this is the smooth and easy prerequisite of assurance rainwater pipe line type.
The rainwater pipe groove excavation is carried out by adopting a mechanical cooperation manual excavation mode: and positioning each rainwater inspection well by adopting a GPS (global positioning system), and discharging a pipeline central line and two side excavation side lines. In the excavation process, a level gauge is used for measuring the excavation depth and the flowing water slope direction, and 10cm is reserved for manual cleaning. And (3) carrying out butt-joint support on the excavated grooves by using wood plates and logs at the interval of 2.5m by using a construction method of excavating and supporting at the same time until the pipeline construction is finished. After the supporting is finished, the construction can be manually carried out at the bottom of the groove.
3. Sleeper beam mounting
And positioning by using a level, arranging a positioning control pile in a straight line section of 10-15 meters, arranging a positioning control pile in a curve section of every 5-10 m, arranging a positioning pile in an intersection of every 5m, and arranging a height control line on the pile by using the level. 1:4, cement mortar grouting is adopted, and a sleeper beam is arranged according to the pipeline axis and the elevation hanging line.
4. Pipe installation
Firstly, the reinforced concrete pipe is checked before the pipe is lowered, and if the reinforced concrete pipe is lowered, the appearance of the reinforced concrete pipe is checked. The appearance quality and the dimensional tolerance meet the requirements of national standard concrete and reinforced concrete drainage pipe (GB11836-89) or the factory standard. The unqualified pipe is not used. The outer wall of the pipe in the pipeline taping range is chiseled by a chiseling machine and residues are removed by a steel wire brush, so that the pipe body and the pipe inside can be cleaned while the technical standard of taping technology is met.
Secondly, the concrete pipe is uniformly lowered mechanically, and the pipe is hung on the side of the groove by a crane and matched manually.
The lower pipe starts from one end of the inspection well, and is careful to smooth operation, so that the rope is prevented from being broken, and the sleeper beam is prevented from shifting due to pipeline collision. The pipe needs to be aligned and straightened in due time when being put down. After the pipe orifices are spliced, the pipe orifices are contracted by using a 5-10 ton chain block, the pipeline is stably installed in place, and the longitudinal clearance is controlled by using a seam-locking method.
And fourthly, when the length of the safety pipe at the inspection well is not consistent with the length of the pipe, the well position is properly adjusted to implement the operation, so that the pipe is prevented from being cut off.
5. Construction of flat foundations and pipe sockets
Erecting formworks on two sides of the pipeline according to specific sizes after the pipeline is installed, erecting the formworks to be straight, smooth and stable, and pouring flat foundations and pipe seats in a layered mode.
Secondly, the concrete for pouring is glidingly poured by adopting the chute, the concrete is poured from one side of the pipeline firstly when the concrete is poured, the lower part of the pipeline can be fully paved by the concrete after being vibrated by the vibrating bar, the lower part of the pipeline can be effectively prevented from generating a gap, and then the pouring and vibrating are carried out from the other side. During pouring, a person is dispatched to enter the pipe to check in time, so that the concrete at the joint of the pipe is guaranteed to be vibrated and compacted, and leaked slurry is treated. During pouring, inserting a steel wire mesh into the joint of the pipeline according to requirements, wherein the depth of the steel wire mesh inserted into the pipe seat is not less than 10 cm.
Before the concrete pipe seat is poured for the second time, the joint concrete is roughened to remove the cement film and loose stone or soft concrete layer on the surface, and the concrete pipe seat is fully moistened and washed clean, and the accumulated water remained on the surface of the concrete is removed, and then a layer of mortar with the same component as the mortar in the concrete is laid and poured.
6. Joint plastering construction
Firstly, wetting the pipe orifice of the part which is roughened in advance for 24 hours before smearing. And (4) cleaning the pipe orifice and brushing plain cement paste.
And secondly, arc-shaped steel side molds are installed on two sides of the steel wire mesh smearing belt connector. The steel wire mesh ensures no rust and scale, and the length of the steel wire mesh is set aside according to the design requirement. The yellow sand in the plastering mortar can be used after being screened. When cement mortar is mixed, the weight of cement and yellow sand should be weighed, and the mixing proportion is controlled well.
Thirdly, a first layer of cement mortar with the thickness of 15mm is smeared and compacted, so that the pipe wall is firmly bonded. Then wrapping the two steel wire nets, wherein the lapping length is not less than 10cm, and firmly binding with lead wires. After the first layer of cement mortar is initially set, smearing a second layer of cement mortar with the thickness of 10mm, carrying out extrusion forming by using an arc-shaped trowel, and finishing and compacting after the initial setting.
Fourthly, filling cement mortar into the inner seam of the pipeline, and trowelling the cement mortar, wherein the mortar is not higher than the inner wall of the pipeline; the inner seam of the pipe seat part is required to be hooked and smeared when concrete is poured.
Utility model discloses a prefabricated super large downspout sleeper beam that accords with the designing requirement is concentrated in batch production, and the required material of preparation component has realized concentrating and has stacked the management and be favorable to reducing dust pollution. The quality of the sleeper beam is better ensured through intensive and industrial construction. Install through using the small-size machines of manual cooperation in the installation, show improvement work efficiency, reduce construction cost for the construction speed, reduce the disturbance to basic structure, energy-concerving and environment-protective, have good economic benefits.
