Description

Technical Field

[0001] The present application relates to the technical field of pipeline construction drainage, and specifically to a pipeline construction drainage structure. Background Art

[0002] To bury the drainage pipe, the first thing is to check the site and arrange the power supply, drainage, earth transportation route, earth storage site and other work. Then, determine the center position of the inspection well and mark the earth excavation line on the ground according to the design drawing. At the same time, set leveling points and control piles along the pipeline. Their positions should not be affected by the construction. When preparations are ready, the pipe can be buried. There are two methods of burying pipes: open excavation, jacking method and shield method without breaking the ground. Open excavation is also called grooving and pipe laying method, which is suitable for small and medium diameter water pipes. During construction, trenches are excavated according to the determined lines.

[0003] For example, a Chinese patent (CN205205842U) discloses a local dewatering structure for a deep foundation pit, comprising: a cushion layer arranged at the bottom of the deep foundation pit; a waterproof layer arranged on the cushion layer; a foundation bottom plate arranged on the waterproof layer; a sump arranged under the cushion layer; a waterproof component arranged in the deep foundation pit, the dewatering component comprising: a pre-buried pipe, one end of the pre-buried pipe is inserted in the sump to form an insertion end, the insertion end is provided with a water permeable hole, and the other end of the pre-buried pipe is exposed from the foundation bottom plate; an upper water stop ring and a lower water stop ring are arranged on the pre-buried pipe, the upper water stop ring is fixed in the foundation bottom plate, and the lower water stop ring is fixed in the cushion layer; and a sewage pump is arranged in the sump.

[0004] The above scheme also has the following technical defects: the above scheme is not convenient for protecting the sewage pump. Since the sewage pump is in the sump, a large amount of mud and sand will enter the sewage pump when pumping water, which may easily cause blockage and damage to the sewage pump. After the sewage pump is damaged, the device needs to be removed to repair the sewage pump, which delays the progress of the project. Based on this, a pipeline construction drainage structure is proposed. Utility Model Content

[0021] Furthermore, ear plates are fixed to both the front and rear ends of the limiting plate, and circular holes are formed on the ear plates, and the bolts slide in the circular holes.

[0022] By adopting the above technical solution, the limit plate is clamped by bolts and nuts.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] 1.
