Steel cylinder with wide tongue and groove fitting

Abstract

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; There is a wide tongue and groove device, and the wide tongue and groove device includes a wide tongue and groove and a protective cover arranged outside the wide tongue and groove. The invention adopts the design of the protective cover, which can effectively protect the wide tenon and groove, and prevent the seabed sediment from entering the wide tenon and groove when the steel cylinder enters the mud, and prevent the steel cylinder from being damaged when it enters the soil layer. The sealing mudguard rubber on the wide tenon groove is torn or damaged; the depth of water injection material pouring is fully guaranteed, so that the water stop material in the wide tenon groove is poured more fully and thoroughly, so that seawater will not enter due to the gap along the bottom of the wide tenon groove The sub-grid steel arc plate affects the water-stop performance of the overall structure of the artificial island; the construction quality of the sub-grid steel arc plate vibration sinking is improved, thereby greatly improving the water-stop performance of the artificial island enclosure structure.

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
