The utility model can not pollute the water body by the diversion of the diversion pipe, has simple and flexible structure, convenient construction, greatly improved construction speed, reduced engineering quantity, reduced pumping drainage operation cost, considerable economy and convenient diversion, and can be widely popularized and applied in the technical field of water conservancy and hydropower engineering.
Description
Technical Field
The utility model relates to the technical field of hydraulic engineering, in particular to a novel pipe groove foundation pit flow guide structure.
Background
In water conservancy projects, construction diversion is one of the most important links, and diversion refers to the construction of permanent buildings such as barrages and hubs on riverways, usually, cofferdams are built on the riverways to form foundation pits, the permanent buildings are maintained to be constructed in dry land, and river water is guided to downstream through a preset drainage channel to be drained. In the prior art, for example, the utility model patent with the application number of CN201910342683.1 applied by the twenty-three group of medium-iron companies discloses a construction method of an open-cut deep foundation pit for crossing a river, the utility model patent with the application number of CN 201821999098.6 applied by the institute of survey and design Limited of China electric construction group discloses a dam type hydropower station construction diversion structure, and the utility model patent with the application number of CN201820764738.9 applied by the group of municipal construction of Wuhan City discloses an underwater broken line diversion structure.
According to different diversion forms, full-section cofferdam diversion and subsection cofferdam diversion exist, and the full-section cofferdam diversion is divided into open channel diversion, tunnel diversion, aqueduct diversion and the like. The diversion mode is characterized in that the open channel diversion is to excavate channels on river banks or beaches, and is suitable for river channels with flat landforms or available beach lands on two banks of rivers so as to excavate open channels. Diversion tunnel diversion is generally used for mountain areas and river channels, tunnels are dug in the convex slopes of the river channels, the diversion tunnel diversion is suitable for river valley narrow, bank slopes steep, rocks are firm, and the river channels suitable for the topographic and geological conditions of the tunnels are arranged. Aqueduct diversion is to erect an aqueduct on a cofferdam for a mountain river with small flow, the river bed is not too narrow, but certain interference is caused to construction, and the aqueduct needs to prevent water leakage. The method is mainly used for the initial stage of engineering, the aqueduct is dismantled after the water delivery building of the main engineering is finished, and river water is released by the water delivery building. Therefore, the traditional diversion mode has the defects of large applicability limitation, multiple working procedures, long construction period, large influence of the earth cofferdam on the water environment and the like.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects that the traditional diversion mode has large applicability limitation, more working procedures, long construction period, larger influence of the building of the earth cofferdam on the water environment and the like, the utility model provides a novel pipe groove foundation pit diversion structure which is mainly applied to the river crossing engineering of a water pipeline and is a diversion mode adopted without cutting off a river or building upstream and downstream cofferdams when the pipe groove is excavated in the river crossing.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a novel chase foundation ditch water conservancy diversion structure, is including setting up the hydraulic pipeline chase on the river course, including arranging the steel sheet pile in hydraulic pipeline chase foundation ditch, including setting up the diversion pipeline on the hydraulic pipeline chase, including setting up the interim cofferdam in diversion pipeline upper and lower reaches.
Further, the diversion pipeline is a steel pipe.
Further, the steel sheet pile is a larsen steel sheet pile.
Compared with the prior art, the utility model can not pollute the water body by diversion through the diversion pipe, has simple and flexible structure, convenient construction, greatly improves the construction speed, reduces the engineering quantity, reduces the operation cost of pumping drainage, has considerable economy and very convenient diversion, and can be widely popularized and applied in the technical field of water conservancy and hydropower engineering.

description of reference numerals: 1-river channel, 2-water pipeline pipe groove, 3-diversion pipeline, 4-temporary cofferdam, 5-steel sheet pile, 6-water flow direction and 7-ground line.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1, the novel pipe chase foundation pit diversion structure of the utility model comprises a water pipeline pipe chase 2 arranged on a river 1, a steel sheet pile 5 arranged in the foundation pit of the water pipeline pipe chase 2, a diversion pipeline 3 erected on the water pipeline pipe chase 2, and a temporary cofferdam 4 arranged on the upstream and downstream of the diversion pipeline 3.
Wherein, the diversion pipeline 3 is a steel pipe. The number of the diversion pipelines 3 is determined according to the flow rate and the pipe diameter. Preferably, the steel sheet pile 5 is a larsen steel sheet pile.
The construction method is carried out according to the following steps in the construction process: (1) and determining the arrangement position of the water transmission pipeline, and constructing a temporary cofferdam 4 at the upstream and the downstream. (2) Building a temporary cofferdam 4 while lowering a steel sheet pile 5; (3) and excavating a foundation pit of the water pipeline pipe groove 2. (4) Laying and erecting a diversion pipeline 3 on a foundation pit of the water pipeline pipe groove 2. (5) And (4) dismantling the temporary cofferdam 4 and carrying out whole-section construction.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
