Steel cylinder with wide mortise device

Abstract

The invention relates to a steel cylinder with a wide mortise device, in particular to a steel cylinder capable of protecting a wide mortise by a protection cover of the wide mortise device. The steel cylinder comprises a cylinder body, wherein the wide mortise device is arranged on the cylinder body and comprises the wide mortise and the protection cover which is arranged outside the wide mortise. Due to the adoption of the design of the protection cover, the wide mortise is effectively protected; when the steel cylinder is sunken into mud, silt of the sea bed is prevented from entering the wide mortise, and when the steel cylinder enters a dirt bed, a sealing mud stop rubber sheet on the wide mortise is prevented from being torn or destroyed; the pouring depth of a water injection material is fully ensured, the filling of a water stop material in the wide mortise is more full and thorough, and the condition that the water stop performance of an artificial island whole structure is influenced as seawater cannot enter an auxiliary grid steel arc plate along a gap in the bottom of the wide mortise is avoided; the construction quality of vibrating, sinking and inserting the auxiliary grid steel arc plate is improved, and the water stop performance of an artificial island space enclosing structure is greatly improved.

Description

technical field [0001] The invention relates to a steel cylinder with a wide tenon and groove device, in particular to a steel cylinder with a wide tenon and groove protected by a protective cover of the wide tenon and groove device. Background technique [0002] In recent years, with the development of offshore artificial islands and coastal seawall revetment projects, there are higher requirements for the overall connection stability and water-tightness of artificial islands; at present, the enclosure structures of artificial islands mostly use large-diameter inserted steel rounds Cylinder structure, wide tongue and groove welded on the wall of the steel cylinder, used as a fixing and guiding structure when the sub-grid steel arc plate is inserted, and also a water-stop structure after the sub-grid steel arc plate is inserted and vibrated and settled; usually A sealing mudguard strip is installed on the wide tenon groove to prevent mud and sand from entering the wide tenon...

[0002] In recent years, with the development of offshore artificial islands and coastal seawall revetment projects, there are higher requirements for the overall connection stability and water-tightness of artificial islands; at present, the enclosure structures of artificial islands mostly use large-diameter inserted steel rounds Cylinder structure, wide tongue and groove welded on the wall of the steel cylinder, used as a fixing and guiding structure when the sub-grid steel arc plate is inserted, and also a water-stop structure after the sub-grid steel arc plate is inserted and vibrated and settled; usually A sealing mudguard strip is installed on the wide tenon groove to prevent mud and sand from entering the wide tenon groove through the tension mouth, but this structure has its disadvantages, which are specifically reflected in: when the steel cylinder sinks or vibrates, the steel cylinder During the mud entry process of the wide tenon groove at the bottom of the barrel, the sediment can easily enter from the gap of the wide tenon groove, and during the mud entry process of the wide tenon groove, the seabed soil layer is very likely to cause damage to the sealing mudguard strip on the wide tenon groove. tearing or damage, thus affecting its sealing performance; if there is too much sediment accumulated in the wide tongue and groove, it will affect the subsequent process—that is, the pouring depth of the wide tongue and groove waterproof material; if the pouring depth of the waterproof material is not enough, it may Let seawater enter, which will affect the water-stop effect of the enclosure structure, and will have an impact on the dry construction environment in the artificial island
