Embodiment 1

[0049] Such as Figure 1~4 As shown, a water-resistant belt, the water-resistant belt 1 includes belt ends at both ends and a plate belt in the middle, the belt ends are thicker than the plate belt, and the belt ends are used to be installed in a reserved channel. The section of the belt end is circular, polygonal or triangular, and the section of the belt end matches the section of the reserved channel, and the specification of the section of the reserved channel is slightly larger than that of the belt end. There is a cavity c in the end of the belt, and the cavity c is used to pass through the in-band grouting pipe 2, and the in-band grouting pipe is used for the lubrication and cleaning of the reserved channels or the grouting of the cavity, and the construction is completed in the water barrier Finally, grouting in the cavity expands the belt end of the flexible waterproof material.

[0050] The water-proof belt 1 is a flexible water-proof material, preferably a flexible...

Embodiment 2

[0052] Such as Figure 5~8As shown, a waterproof structure between prefabricated components of the above-mentioned water-resistance belt includes prefabricated components, and the prefabricated components are pipe joints. The opposite end faces of the joints, or the outer end faces adjacent to the opposite end faces of two adjacent pipe joints. Specifically, the pipe joints include upper and lower pipe joint permanent structures 6 (such as concrete and steel structures) and left and right pipe joint temporary structures 7 (such as steel structures), and the reserved channels d are arranged on the pipe joint permanent structures 6 .

[0053] The installation of the water-repellent belt needs traction. The front side of the water-resistant belt 1 is connected with the traction rope 5 through the steel splint 3, the rivet 4, and the traction rope 5 is connected with the traction equipment 11. The traction equipment can adopt a hoist. Through the dragging of the traction equipmen...

Embodiment 3

[0058] A construction method of the above-mentioned waterproof structure between prefabricated components includes the following steps.

[0059] Step a, such as Figure 13 As shown, when the prefabricated components are produced, the pre-buried channels are constructed according to the needs. After the prefabricated components are assembled and constructed, the drilling construction of the traction holes of the water barrier is carried out. The drilling equipment 10 is used to drill the traction holes on the outside of the prefabricated components. The component gap is drilled from one end of the working well to the other end of the working well, and the rear end of the drilling device 10 is connected with the traction rope 5 . Such as Figure 14 As shown, after the traction hole is penetrated, the drilling equipment is removed, and the traction equipment 11 is installed to install the water barrier 1 .

[0060] Step b, such as Figure 15 As shown, the installation and cons...

Abstract

The invention provides a waterproof band, a waterproof structure between prefabricated parts and a construction method. The waterproof band comprises a plate band, wherein a band end which is thickerthan the plate band is arranged on the end of the plate band. The waterproof structure comprises two adjacent prefabricated parts, wherein reserved channels are formed in the prefabricated parts, thewaterproof band is arranged between the two prefabricated parts, and the band ends of the waterproof band are arranged in the reserved channels, so that the waterproof band has a waterproof function in a gap between the two prefabricated parts. The construction method comprises the step of arranging the band end on the end of the waterproof band in the reserved channels of the prefabricated partsafter the prefabricated parts are assembled and constructed so as to form the waterproof structure in the gap between the two adjacent prefabricated parts. The waterproof structure has the advantagesthat the problems of difficulty in sealing and water isolation and waterproof construction between the two adjacent prefabricated parts are solved, the gap between the two adjacent prefabricated partsis blocked through the waterproof band, the waterproof effect between the two adjacent prefabricated parts is effectively guaranteed, the structure is simple, and construction is convenient.

Description

technical field [0001] The invention relates to waterproofing technology, in particular to a waterproof structure and a construction method between a water barrier and prefabricated components. Background technique [0002] With the in-depth advancement of infrastructure construction such as sponge cities, urban three-dimensional transportation, and civil air defense projects in my country, the sections of underground projects are diversified. In the future, construction fields such as underground commercial complexes, subway projects, underground parking lots, comprehensive utility corridors, highway and railway tunnels or box culverts will have a large number of diverse cross-sectional space development needs. [0003] For large-section underground projects, tunneling machines such as shield tunneling or pipe jacking are often used to excavate in units. During the excavation process of the tunneling machines, the matching pipe joints of the tunneling machines of each unit ...
