Abstract

The invention discloses a ground beam type ditch which comprises ditch walls, a ditch cover, a ditch bottom and embedded parts. The ditch bottom is arranged at the bottom of the ditch. The ditch walls are arranged on the two sides of the ditch bottom, and the ditch bottom is connected with the bottoms of the ditch walls. The ditch cover is arranged on the upper portions of the ditch walls, and the embedded parts are arranged in the inner walls of the ditch walls. The ditch bottom is provided with a water draining hole, and the position, corresponding to the water draining hole, of the bottom of the ditch bottom is provided with a rubble layer. The ditch bottom is arranged on a foundation, the ditch walls are arranged on the two sides of the ditch bottom, and the ditch bottom is connected with the bottoms of the ditch walls. The ditch cover is arranged on the upper portions of the ditch walls, and the ditch walls, the ditch cover and the ditch bottom form a cavity. A cable or a pipeline can be arranged in the formed cavity, and the embedded parts can be used for fixing a cable support or the pipeline. The water draining hole is formed in the ditch bottom, the rubble layer is arranged at the position, corresponding to the water draining hole, of the bottom of the ditch bottom, water flowing into the ditch from a ditch cover gap can be easily drained out of the ditch, water is not accumulated in the ditch, the cable or the pipeline is prevented from being steeped in water. Meanwhile, due to the fact that the rubble layer is used for draining water, the water draining problem under the condition that a water draining system does not exist near the ditch is solved.

Description

technical field

[0001] The invention belongs to the technical field of thermal power generation, in particular to a ground beam type trench. Background technique

[0002] Cable trenches and pipe trenches are an important part of thermal power plants and one of the common trenches inside power plants.

[0003] Existing cable trenches and pipe trenches are composed of trench walls, trench bottoms and trench cover plates. The material is reinforced concrete. Temporary trenches can be laid with bricks. There are embedded parts inside the trenches to fix cable supports or pipes. . Both the cable trench and the pipe trench are independent trenches, which are mainly used to solve the drainage problem of the trench. The conventional practice is to raise the trench surface by 100 mm above the bottom surface to prevent rainwater from entering the trench; and, in the trench In addition, a drainage pipe is connected to the nearby drainage system to ensure that there will be no water a...
