Abstract
The waterproof method for the deformation joint of the underground pipe gallery comprises the following steps: and a rubber water stop is arranged at a gap between the two pipe galleries, and the center of the rubber water stop is coincided with the center line of the deformation joint. The rubber waterstop is assembled in advance on the lap joint part before being installed, the position to be overlapped is determined by drawing a line, the position of a raw rubber sheet which is about 1cm left in the middle is required to be guaranteed when the line is drawn, rubber at one end of the rubber waterstop with a steel edge is cut into the rubber sheet by about 30cm by a cutting machine, and rubber parts at two ends of the rubber waterstop which are to be overlapped are ground flat by an angle grinder. The waterproof method for the deformation joint of the underground pipe gallery provided by the invention can seal and waterproof the joint of the pipe gallery.
Description
Technical Field
The invention relates to the technical field of underground pipeline construction, in particular to a waterproof method for deformation joints of an underground pipe gallery.
Background
The utility tunnel excavation supporting mode has the slope of putting and spouts anchor and steel sheet pile to strut, and the major structure is reinforced concrete from waterproof system, uses the structure to be waterproof from being fundamental promptly, and seam such as construction joint, movement joint is waterproof as the key, is assisted waterproof enhancement layer waterproof, and waterproof mainly adopts water proof coating to add the coiled material waterproof, and the engineering has long service life, the corridor pipeline is many, buries deeply relatively, later maintenance characteristics such as difficult. By combining the characteristics of the projects, the reliability of water resistance is absolutely guaranteed in view of safety because the corridor pipelines have various pipelines such as high-voltage lines and the like; in addition, the main body of the pipe gallery is buried deeply, and according to the engineering geological conditions, particularly in the areas with high underground water level, the waterproof requirement ensures that the pipe gallery is free of seepage points in all directions; the piping lane belongs to underground buried depth thing, and later stage waterproof restoration is maintained comparatively difficultly, therefore waterproofly need follow "prevent, arrange, cut, stifled" combination principle, but the focus is on preventing.
Disclosure of Invention
In view of the above current situation, the embodiment of the invention provides a waterproof method for deformation joints of underground pipe galleries, and solves the problem of waterproof of the joints between the two pipe galleries.
The waterproof method for the deformation joint of the underground pipe gallery comprises the following steps:
installing a rubber water stop at a gap between the two pipe galleries, wherein the center of the rubber water stop is coincided with the center line of the deformation joint;
the method comprises the steps of trial splicing the rubber waterstops in advance before installing the rubber waterstops, drawing a line to determine the position to be lapped, ensuring that a position of a raw rubber sheet is left in the middle of the rubber waterstops, cutting rubber at one end of the rubber waterstops with a steel edge into the rubber sheet by a cutting machine for about 30cm, grinding the rubber parts at two ends of the rubber waterstops to be lapped by an angle grinder, cushioning the lower parts of a clamp preheated in advance under the rubber waterstops to be lapped, filling the raw rubber sheet at the lapped parts, installing the clamp and placing a jack, controlling the temperature within the range of 130 ℃ and 150 ℃, heating and pressurizing while heating to ensure that the clamp is tightly attached to the surfaces of the rubber waterstops, keeping the clamp for about 10 minutes, then detaching the clamp, and filling gaps between the rubber waterstops and deformation gaps by adopting low-foaming polyethylene caulking plates and two-component polyurethane sealing paste.
The waterproof method for the deformation joint of the underground pipe gallery provided by the invention can seal and waterproof the joint of the pipe gallery.
