Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Such as Fig. 1, shown in Fig. 3 and Fig. 4, the present embodiment provides a kind of with the sealing system between end component and underwater concrete bedding, including member body, tremie 2, Grouting Pipe (is omitted in figure) and cushion block 3, described member body includes base plate 11, outer panel 12 and interior plate 13, the end of the periphery of described outer panel 12 and described base plate 11 fixes the large cavity connecting and composing upper opening, described interior plate 12 be positioned at described base plate 11 medium position and with base plate 11, large cavity is divided into multiple little cavity 14 by outer panel 12 fixing connection, the base plate 11 of each little cavity 14 offers injected hole 111, described tremie 2 is fixing connects described injected hole 111, described Grouting Pipe removably connects described tremie 2, cushion block 3 is removably sticked on described base plate 11.It should be noted that base plate 11 can be the rule such as plane, curved surface face or other irregular, the material with end component can be concrete, steel or other meet the material of bedding mechanical property. Element structure at the bottom of band in the present embodiment is reliable and stable, be suitable to the construction of underwater concrete bedding 5, concrete is injected in foundation trench 41 through Grouting Pipe, tremie 2, injected hole 111, decrease the step through the floating bedding of underwater construction person, make work progress simpler, but also make the end face of underwater concrete bedding 5 and the laminating Du Genggao with end component, improve the stability that structure is overall.
As in figure 2 it is shown, underwater concrete bedding of the prior art construction, foundation trench 41 is offered in first bottom surface 4 under water, then adopts the mode directly building underwater concrete to water foundation trench 41, through underwater construction person, concrete is carried out floating process. After concrete bedding 5 reaches requirement of strength, prefabricated components are directly placed on concrete bedding 5. Underwater performance circumstance complication in this work progress, difficulty is big, and the requirement of diver is higher; If it addition, the roof handling of concrete bedding 5 is uneven so that the closely knit difference of end face of prefabricated components and concrete bedding 5, superstructure is unstable, affects whole structural stability.
As shown in Figure 3 and Figure 4, the present embodiment provides a kind of with the sealing system construction method between end component and underwater concrete bedding, comprises the following steps:
Step one, foundation trench 41 is offered in bottom surface 4 under water, processes the basis of cushion block 3 pre-placing position;
Step 2, is positioned in foundation trench 41 by cushion block 3, adjusts the height of cushion block 3 according to practical situation;
Step 3, connects tremie 2 by Grouting Pipe;
Step 4, is positioned on cushion block 3 by member body, adjusts the plan-position of member body;
Step 5, injects non-dispersible underwater concrete in foundation trench through Grouting Pipe, tremie, injected hole.
When foundation trench 41 is more smooth, above-mentioned steps two can be replaced the height adjusting cushion block 3 according to practical situation, and cushion block 3 is sticked on base plate 11, step 4 can be replaced and member body is positioned in foundation trench 41 together with cushion block 3, and adjusts the plan-position of member body. So before member body enters in water, complete the combination of cushion block 3 and member body and the connection of Grouting Pipe and tremie 2, thus simplifying underwater performance flow process. Non-dispersible underwater concrete injects after in foundation trench, and cushion block 3 is also made cushion block 3 become a part for underwater concrete bedding by non-dispersible underwater concrete parcel in the lump. The height of the cushion block 3 in above-mentioned steps two and step 3 and the deep equality of foundation trench 41, making non-dispersible underwater concrete be injected in foundation trench 41 makes concrete capable of not dispersing and base plate 11 fit tightly, naturally it is also possible to place flexible material (such as anticorrosive wood, high-performance rubber material etc.) at the top of cushion block 3 and the elevation with end component on cushion block 3 is adjusted. Said method makes full use of the Self-leveling characteristic of non-dispersible underwater concrete, it is achieved " soft boldly confront a powerful opponent ", improves the compactness with end component Yu concrete bedding 5, make structure more stable, and it is floating under water to be further without diver, reduce workload, reduce the risk of underwater operation. Said method is more suitable for complex condition, such as foundation trench 41 out-of-flatness, by adjusting height and the position of cushion block 3 before installing with end component, the basal surface position with end component etc. can be adjusted quickly and easily, be unlikely to make the run-off the straights such as component at the bottom of band cause danger.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, the change made in the essential scope of the present invention of those skilled in the art, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
