Problems solved by technology

When the pipes are installed in the groove, the integrity and stability are low, which is easy to cause the pipe to deviate, and the straightness of the pipe installation cannot be guaranteed; after the pipes are connected to each other, it is easy to cause the end of the pipe to collide with the side wall of the groove

Embodiment 1

[0049] Embodiment 1, the construction method of sewage pipeline, as figure 1 as shown,

[0050] Pre-construction preparations, inspection of each construction equipment and site to check whether the construction equipment is in good condition and whether the construction site is safe.

[0051] Earthwork development: Excavating foundation pits and inspection wells.

[0052] Foundation pit excavation and other earthworks are mainly constructed by excavators.

[0053] The downpipe line section can only be excavated manually, and after the excavation is 20-30cm away from the design elevation, it will be leveled manually to avoid over-excavation and disturbance of the soil foundation. The soil to be transferred shall be transported by dump truck.

[0054] Excavation of the foundation pit shall be carried out in layers and sections in sequence. When excavating layer by layer and below the groundwater level, set up drainage ditches and water collection wells. , Its length × wid...

Embodiment 2

[0084] Embodiment 2, it differs from Embodiment 1 in that, as figure 2 As shown, in step , that is, in the step of "sideline and base setting", further operations are performed on the base:

[0085] First: adjust the distance between the two opposite bases to be the same as the diameter of the pipe, and then the base is fixed in the foundation pit by concrete.

[0086] Again: support ropes are set between two relative bases, and the ropes are hemp ropes. Pull one end of the rope to adjust the length of the rope between the bases; if the height of the pipe is lower than the sideline, tighten the rope so that the rope raises the pipe, and fix the rope after the height of the upper end of the pipe is equal to the sideline;

[0087] If the pipeline is higher than the sideline, loosen the rope. After the rope is loose, the height of the pipeline is lowered. After the height of the upper end of the pipeline is equal to the sideline, the rope is fixed. The rope is fixed to the bas...

Embodiment 3

[0090] Embodiment 3, for the base in the method of embodiment 1 or embodiment 2. Such as image 3 and Figure 4 As shown, a pedestal includes a pedestal body 1, and two pedestals are arranged facing each other to form a group. The facing surfaces of the two pedestal bodies 1 are vertical surfaces, and the pedestal body 1 is divided into an upper part and a lower part. The cross-section of the lower part of the pedestal body 1 It is in the shape of a right-angled trapezoid, and the cross section of the upper part of the base is rectangular.

[0091] The upper end of the seat body 1 is provided with a hanging hole 2, and the hanging hole 2 is used for hooking the hook of the lifting equipment to fix it.

[0092] The lower part of the seat body 1 is provided with a perforation 3 , and two opposite seat bodies 1 are provided with a rope 4 , the rope 4 is shot through the two through holes 3 , and the rope 4 can move on the perforation 3 . The two ends of the rope 4 are wrapped ...

Abstract

The invention discloses a construction method of a sewage pipeline and bases, for solving the problem that when a pipeline is mounted in a ditch, the integrality and stability are poor, the deviationof the pipeline is easily caused, and the mounting straightness and smoothness of the pipeline can not be guaranteed. The key points of the technical scheme are as follows: the construction method ofthe sewage pipeline comprises the following steps: 1, excavating a foundation pit and an inspection well; (2) hanging a side line for pipe alignment in the foundation pit according to the central point of the inspection well and the center line of the pipeline, and controlling the trend and elevation of the pipeline by utilizing the side line; (3) placing pipeline in the foundation pit, connectingthe adjacent pipelines according to the straightness and height of the side line, wherein the straightness is kept between the adjacent pipelines according to the side line, and the pipelines are connected; and (4) backfilling the foundation pit. Each base comprises a base body, and a rope is arranged between the two bases, a puncturing hole is formed in each base body, a pull piece used for winding of the rope is arranged on each base body, then positioning for the pipelines is realized by utilizing the side line and the bases, so that the straightness and smoothness are guaranteed during pipeline connecting and mounting.

Description

technical field [0001] The present invention relates to this sewage pipeline project, more specifically, it relates to a kind of construction method of sewage pipeline. Background technique [0002] Rural domestic sewage treatment is not only an important part of improving people's livelihood, but also one of the most urgent, urgent and prominent problems in the construction of new countryside in Yongkang City, which has important practical significance. In the existing rural domestic sewage treatment system, the domestic sewage is drained through pipelines, and the sewage is uniformly converged to the sink for treatment. The construction of sewage pipes is an important link in the rural domestic sewage treatment system. [0003] During the construction of rural sewage pipelines, according to the conventional construction method (trench excavation→cushion (flat foundation) pouring→pipeline installation→pipe seat pouring→backfilling), the construction period of two times of ...
