Abstract

The utility model discloses an underground pipe channel, relates to the pipeline technology, and aims at resolving the problem that the function of the prior underground pipe channel is single. A waterproof wall that extends along the axial direction of the underground channel is arranged inside the underground pipe channel; the waterproof wall divides the underground pipe channel into two independent passages. The underground pipe channel is mainly used for arranging the electrical and water-supply pipelines and for discharging the water of the building or discharging the ground rain water.

Description

Underground pipe trench

Technical field

The utility model relates to a kind of pipe technology, is specifically related to a kind of underground pipe trench.

Background technology

Building is generally used for laying various pipelines between land used red line (being used to indicate the line of planned land use scope), but because project planning land used scope is less, the words that the pipeline that lays if desired is many especially, also be difficult to all pipelinings appropriately even exceed the pertinent regulations of land use of country, the pipeline maintenance work after this makes and lays is difficulty very.

As shown in Figure 1, existing underground pipe trench comprises the pipe trench body, is provided with well lid between pipe trench body and the ground, and pipeline body is used to lay multiple pipeline.This design has solved the difficult problem of laying the line to a certain extent, but can only be used to lay electric pipeline or the pipeline close with its function, and function singleness is difficult to be used to simultaneously carry living water use, electrical conduits and rain soil pipe.

The utility model content

The utility model provides a kind of underground pipe trench, and this underground pipe trench not only can solve the problem of the difficulty of laying the line but also have discharging rainwater function.

For achieving the above object, the utility model has adopted following technical scheme:

This underground pipe trench comprises the pipe trench body, is provided with the mine dam that extends along underground pipe trench axial direction in the pipe trench body, and described mine dam is divided at least two independently passages with underground pipe trench.

Compared with prior art be provided with the mine dam that extends along underground pipe trench axial direction in the underground pipe trench of the utility model, mine dam is divided at least two independently passages with underground pipe trench, one of them passage is used to lay electric or close function pipeline, and other passages can be used for feedwater piping and lay, discharge rainwater or other functions.Mine dam can avoid being used for the influence to other passage gut lines of rainwater in the passage of draining or moist air stream.So this underground pipe trench not only can solve the problem of the difficulty of laying the line but also have the water supply and draining function.

Description of drawings

Fig. 1 is the cross-sectional configuration schematic diagram of underground pipe trench in the prior art.

Fig. 2 is the cross-sectional configuration schematic diagram of the underground pipe trench of the utility model.

The specific embodiment

Be provided with the mine dam that extends along underground pipe trench axial direction in the underground pipe trench of the utility model in the underground pipe trench, mine dam is divided at least two independently passages with underground pipe trench, one of them passage is used to lay electric or close function pipeline, and other passages can be used for carrying living water use, sewage effluent or other functions.Mine dam can avoid being used for the influence to pipeline of sewage in the passage of draining or moist air stream.

Below in conjunction with accompanying drawing the utility model is further elaborated:

As shown in Figure 2, be provided with a stifled mine dam that extends along underground pipe trench axial direction in this underground pipe trench body 1, mine dam is divided into independently two independently

passage

2,3, i.e. water transport channel 2 and electrical path 3 with underground pipe trench.

Be provided with the water service pipe 22 that is used to transmit living water uses such as tap water in the water transport channel 2, and be arranged on the rainwater water inlet pipe 23 of water transport channel 2 tops or sidewall and the chute 21 of water transport channel 2 bottoms, rainwater flows into the water transport channel bottom from rainwater water inlet pipe 23, flows and final discharging in the water transport channel lower space.Feedwater and close function pipelining are in this passage upper space.Residual catchmenting in a small amount of rainwater of chute 21 dischargings or the passage.Among Fig. 2 water transport channel 2 bottoms also be provided with according to the direction of arrow among Fig. 2 descend successively domatic.Electrical path 3 is used to lay various pipelines 31, and for example optical cable, broadband etc. are because mine dam for can bear the mine dam of one-sided water pressure, influence so moist air stream in the water transport channel 2 or rainwater can not constitute the various pipelines in the electrical path 3.

Water transport channel 2 can be made current formula, half current formula or obstructed line according to the actual needs with electrical path 3.The current underground pipe trench of formula also is provided with and highly is not less than 1.8 meters walkway except that channelling, and the staff can enter in the pipeline and make an inspection tour, overhaul and change pipeline.Be used in the place of unsuitable excavated pavement more.Should have when underground pipe trench is longer and ventilate and illumination.In the intensive downtown area of underground utilities, heating line also can also can be provided with the heating line cell separately with current synthetically the descending in the pipe trench that be laid in of other pipelines.Obstructed its size of line buried pipe ditch is only considered the pipeline construction operating condition, and the staff can not enter.This underground pipe trench cross dimension is little, and cost is lower.The half current underground pipe trench of formula is between current underground pipe trench and the underground pipe trench of no thoroughfare, and the walkway size in the underground pipe trench is less, and the staff can only make an inspection tour and simple operations.

Be provided with a plurality of inspection holes that are provided with lid 4 between water transport channel 2 and the ground and between electrical path 3 and the ground, can overhaul various facilities in water transport channel 2 and the electrical path 3 at any time by inspection hole.

The utility model is mainly used in the underground pipe trench of building, municipal administration etc., can concentrate in this underground pipe trench and lay electric, water-supply line and discharging building roofing or ground rainwater.
