The embodiment of the utility model provides a drainage system of piping lane, mainly satisfy the structure percolating water of discharge piping lane 1, the requirement of ground sparge water and pipeline maintenance unloading drainage in the piping lane 1, wherein regular drainage has the structure percolating water of piping lane 1 and ground sparge water in the piping lane 1, the displacement is less, need follow 1 vertical slopes of piping lane through escape canal gravity row to the sump pit of 1 interval minimum of piping lane, irregular drainage overhauls unloading drainage for the intake of corridor water pipe, the displacement is big, but just can the drainage when only overhauing the unloading. The embodiment of the utility model discloses a can be used for non-excavation formula utility tunnel and excavation formula utility tunnel.
Referring to fig. 1, 2, and 3, an embodiment of the present invention provides a drainage system for a pipe gallery including a sump 2, a first drainage mechanism, and a second drainage mechanism. The pipe gallery 1 has a plurality of drainage intervals, each drainage interval having a longitudinal slope forming one or more lowered positions. For example, in the embodiment shown in fig. 1, a drainage interval is formed between two adjacent working wells, the drainage interval has a V-shaped slope, and a low-lying position is formed at the lowest point. The first drainage mechanism comprises a first drainage pump 31 for delivering water in the water collection pit 2 out of the pipe gallery 1; the second drainage mechanism comprises a second drainage pump 32 for sending the water in the water pipe 11 of the gallery out of the pipe gallery 1.

Second drain pump 32 and income corridor water piping connection back, directly through absorbing water tub from the water pipe 11 of income corridor, because the water pipe 11 diameter of income corridor is big, and second drain pump 32 arranges the low-lying position at piping lane 1, and the income corridor water pipe 11 of second drain pump 32 both sides all is higher than the water tub that absorbs of second drain pump 32 in the elevation, guarantees like this that second drain pump 32 can be in the state that the malleation was absorbed water. In the embodiment, the movable second drainage pump 32 is adopted, the second drainage pump 32 can be shared among a plurality of drainage intervals, the number of matched components such as the second drainage pump 32 is greatly reduced, the investment is saved, the workload of operation and maintenance is reduced, and the operation cost is reduced.
According to the type and the characteristics of the drainage in the pipe gallery 1, the drainage in the pipe gallery 1 is divided into two parts by adopting the form that the water collection pit 2 under the pipe gallery 1 is matched with the first drainage pump 31 for drainage and the second drainage pump 32 for drainage are arranged in the pipe gallery 1, the structure leakage water of the pipe gallery 1 and the ground flushing water in the pipe gallery 1 can be discharged by the first drainage pump 31 under the bottom plate of the pipe gallery 1, the emptying drainage during the overhaul of the pipeline of the pipe gallery can be discharged by the second drainage pump 32 arranged on the ground in the pipe gallery 1, the combination and the application of two different water pump arrangement schemes effectively solve the defects that the traditional method only arranges the underground water collection pit 2 for large-flow selection of the drainage water pump, the size of the water collection pit 2 is large, the construction difficulty is large, the construction risk is effectively reduced, the safety influence of the construction of the water collection pit 2 on the structure of the pipe gallery 1 is reduced, meanwhile, the requirement for the drainage of, the construction period is effectively shortened.
Referring to fig. 2 and 3, the system further comprises a drain main 33, the drain main 33 is laid along the pipe gallery 1, the first drain pump 31 is connected with the drain main 33 through a first drain pipe 34, the second drain pump is connected with the drain main 33 through a second drain pipe 35, the first drain pipe 34 is provided with a first control valve 36, and the second drain pipe 35 is provided with a second control valve 37. The drain header pipe 33 is used to send the water of the first drain pump 31 and the water of the second drain pump 32 out of the pipe rack 1, and the drain header pipe 33 can send the water of a plurality of low-lying positions in a plurality of sections out of the pipe rack 1.
One or more first drainage pumps 31 are provided, for example, in some embodiments, referring to fig. 3, 2 first drainage pumps 31 are provided, 2 first drainage pumps 31 are connected in parallel, and 1 is used for 1, and the first drainage pumps are started simultaneously when necessary.
In some embodiments, a plurality of water level sensors (not shown) are provided along the depth direction of the sump 2. The water level sensor is used for detecting the water depth in the sump 2 and starting one first drainage pump 31 or a plurality of first drainage pumps 31 according to different water depths, for example, when the water depth in the sump 2 is shallow, the plurality of first drainage pumps 31 are all stopped, when the water level rises, the first drainage pump 31 is started, and the like, so that the drainage efficiency is better.
The first drainage pump 31 may be a centrifugal pump, a submersible pump, or the like, for example, in the embodiment shown in fig. 2 and 3, the first drainage pump 31 includes a submersible pump provided in the sump 2. The immersible pump is arranged in the sump 2, and the space of the pipe gallery 1 is saved. Because the structure leakage water of the pipe gallery 1 and the drainage of the ground washing water in the pipe gallery 1 are small, only a small-flow submersible pump (with the flow of about 10-30 m) is needed to be arranged3H, about one tenth of the existing scheme) and small-size sump 2 (length 1.7m x width 1.4m x depth 2m), because the drainage of underground sump 2 does not need to consider the gallery pipeline to overhaul and empty the drainage, so the flow of submersible pump and the size of sump 2 are all greatly reduced, the submersible pump of small flow has small size and light weight, and the transportation, installation, overhaul and maintenance in pipe gallery 1 are all very convenient.
