Embodiment Construction
[0038] Attached to the following Figure 1-4 This application will be described in further detail.
[0039] This embodiment discloses a water-guiding and intercepting structure and a construction method for a coastal double-row steel sheet pile cofferdam. refer to figure 1 , a coastal double-row steel sheet pile cofferdam diversion and interception structure, including a combined dragon warehouse 2, the two sides of the combined dragon warehouse 2 are provided with a number of diversion warehouses 1. In the present application, a diversion chamber 1 is provided on both sides of the combined dragon chamber 2 .
[0040] refer to figure 1 , the diversion bin 1 includes a first purlin 11 , a diversion pile wall 12 , an interception pile wall 13 and two transverse partition pile walls 14 . The diversion pile wall 12 , the interception pile wall 13 and the two transverse partition pile walls 14 are all arranged around the first surrounding purlin 11 , and the two transverse part...

This application relates to the technical field of water conservancy engineering, and discloses a construction method for diversion and interception of comb-tooth grooves in coastal double-row steel sheet pile cofferdams. The diversion chambers are arranged on both sides of the closing dragon warehouse, and the diversion chambers include two transverse pile walls. , there is a diversion pile wall and an interception pile wall between the two transverse pile walls, and a diversion structure is arranged on the diversion pile wall, and the diversion structure includes a first Block and fixed box, the fixed box is located directly below the first stop, the density of the fixed box is greater than the density of water, the fixed box slides along the vertical direction on the diversion pile wall, and a fixed groove is provided above the fixed box to fix The groove is provided with a fixing hole on the inner wall of the guide pile wall, and the side of the guide pile wall facing the fixed box is provided with a water inlet hole. The movement of the fixed box in the vertical direction can make the fixing hole and the water inlet hole communicated / staggered. The application has the effect of reducing the risk and difficulty of cofferdam closure construction.
Description
technical field [0001] The present application relates to the technical field of water conservancy projects, and in particular, to a water-guiding and intercepting structure and a construction method for a coastal double-row steel sheet pile cofferdam. Background technique [0002] At present, the double-row steel sheet pile cofferdam refers to the temporary enclosure structure built for the construction of permanent water conservancy facilities during the construction of water conservancy projects. [0003] The cofferdam construction in the related art adopts a construction scheme in which both ends are gradually advanced to the middle. [0004] In view of the above-mentioned related technologies, the inventor believes that in the coastal environment, the cofferdam closure will be affected by the fluctuation of the tide, and the tide will increase the water flow at the cofferdam closure, which will cause the Helong steel sheet pile to swing, causing the Helong steel sheet p...
