Abstract
A leakage detecting device for a watertight door of an immersed tunnel comprises a water tank, a test platform and an increasing air pump. The water tank is composed of a bottom panel, a top panel and side panels, one side end of the water tank is open, connecting plates are arranged on the periphery of the opening end and provided with connecting holes, and the increasing air pump is connected with the water tank through a valve. The test platform is composed of a main panel, cross beams, vertical beams, a hand wheel and pull rod system and a hinge. Through holes corresponding to the connecting holes in the connecting plates of the water tank are formed in the periphery of the main panel. The connecting holes in the connecting plates of the water tank and the through holes in the main panel are connected through fastening bolts. The main panel is provided with observation holes. The hinge is arranged on the outer end face of the main panel. Fixing box iron of the hand wheel and pull rod system is installed on the inner end face of the main panel. One end of each pull rod is connected with a handle wheel, and the other end of each pull rod is a free end and penetrates the fixing box iron and the main panel. Due to the fact that the test platform and the water tank are adopted as test tools, operation is easy and convenient, the watertight door can be subjected to leakage detection in a workshop in advance, the construction period of the immersed tunnel can be greatly shortened, and the work efficiency is improved.
Description
Technical field
The present invention relates to immersed tube tunnel technical field of construction, especially a kind of immersed tube tunnel watertight door leakage detection apparatus.
Background technology
At present, in immersed tube tunnel is constructed, each docking site of pipeline section is respectively provided with end envelope wall, for temporary enclosed, water proof, after treating pipeline section docking, in succession draws water, removes envelope wall. Watertight door is a temporary part of immersed segment, it is made up of steel beam column, it is arranged on the side near water of structure, no matter it is mounted in the watertight door on concrete end envelope wall, also it is mounted in the watertight door on steel construction envelope wall, under construction period, normal applying working condition, require to bear the head pressure of maximum 30m and non-leakage, require that watertight door must carry out workshop water-pressure sealed test (test pressure 0.3MPa after completing, constant voltage time 24 hours), to verify the sealing property of watertight door, it is ensured that do not drip, do not seep water. During immersed tube section floating, sinking, watertight door is as there is percolating water situation, consequence is hardly imaginable, even affect the service life in tunnel, therefore, steel end seal up a door on watertight door effect great, infiltration detection must be carried out before use, how quickly detection watertight door whether percolating water is always up a technical barrier.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, the immersed tube tunnel watertight door leakage detection apparatus that easy to operate, work efficiency is high.
The immersed tube tunnel watertight door leakage detection apparatus of the present invention, including water tank, test platform, increase air pump, it is characterized in that, water tank is made up of bottom panel, top panel and three pieces of side panels, side end opening, opening is formed around connecting plate, and connecting plate has evenly distributed connecting hole, increases air pump and is connected with water tank by valve, connecting tube, water tank top panel, test platform is by main panel, anyhow beam, handwheel tie system, hinge is constituted, anyhow beam is affixed with main panel inner face, main panel surrounding has the through hole corresponding with connecting hole on water tank connecting plate, on water tank connecting plate, connecting hole is connected with the through hole fastening bolt on main panel, main panel is provided with observation port, hinge is arranged on main panel outer face, the fixing channel-section steel of handwheel tie system is arranged on main panel inner face, hands is taken turns, pull bar is fixing on the home panel by fixing channel-section steel, one end of pull bar is connected with handwheel, the other end is that free end is through fixing channel-section steel and main panel.
The operation principle of the immersed tube tunnel watertight door leakage detection apparatus of the present invention is, first the hinge auricle on watertight door is passed through door stud connection with the hinge on test platform main panel outer face, again the pull bar auricle on watertight door is connected with the pull bar free end bearing pin of handwheel tie system, and places sealing rubber strip at watertight door lip.Rotation hand wheel, the sealing lip of watertight door surrounding, sealing rubber strip and test platform main panel outer face are fitted tightly by pull bar. Afterwards, water tank is buckled on test platform, test with between platform main panel and water tank connecting plate contact surface with rubber blanket and round steel compression, and tighten with fastening bolt and guarantee not permeable leaking. Water filling in water tank, after filling, starts supercharging air pump and water tank is pressurizeed, and pressure stops pressurization after reaching 0.3MPa, closes valve, keeps constant voltage 24h. By the observation port on main panel, percolating water situation in viewing test process.
The immersed tube tunnel watertight door leakage detection apparatus simple in construction of the present invention, owing to adopting test platform and water tank as test instrument, simple and convenient, watertight door can be hunted leak in advance in workshop, is substantially shorter the immersed tube tunnel construction period, improves work efficiency.
