Aerosol valve actuator

An aerosol valve actuator with a valve stem engaging portion, product dispensing opening, and flexible and expandable product conduit between the engaging portion and dispensing opening. The product conduit is molded at least in part of a first expandable flexible plastic material softer than a second plastic material of the remainder of the actuator. The remainder of the actuator is first molded, followed by molding the first plastic material to form at least a part of the product conduit. After the actuator has been actuated to dispense a foaming product and actuation ceases, the post-foaming product expands within the product conduit since the conduit expands to absorb the product expansion. Actuator cap and base product dispensing side openings align only during valve actuation. Base inwardly flexible members and cap internal ramps bias the cap upwardly when actuation ceases. Base upper portion telescopes in base lower portion during actuation.

Excavation and support method of large cross-section tunnel through fault fracture zone

The invention discloses an excavation and support method of large cross-section tunnel through fault fracture zone. The initial support structure of tunnel comprises a whole cross-section support system and the lattice girder and shotcrete support structure of the tunnel. A temporary support structure of middle-partition wall is arranged between a left pilot tunnel and a right pilot tunnel. The actual construction includes the steps: 1, excavation of the upper tunnel body; 2, the judgment of the initial support deformation of the tunnel arch wall and the construction of the replacement arch; 3, excavation of the lower tunnel body. The excavation and support method of large cross-section tunnel through the fault fracture zone has reasonable design, simple construction, and good use effect.Only the upper half section of the tunnel is excavated by the center diaphragm method, and the excavation cross-section is reduced so that the stability of the arch roof is ensured. The whole cross-section support system and the temporary support structure of middle-partition wall are supported by the underpass beam and joined together to form a stable monolithic support system, which can avoid the sinking of the supporting arch and ensure the stability of the initial support effectively. Besides, the construction of replacement arch is conducted on only half cross-section of the tunnel and the cost can be saved, and the construction safety can be ensured.
