Abstract
A disturbance-resistant pipe jacking construction scheme is suitable for construction of urban underground passages over streets and other underground projects. A thin steel plate is laid between a prefabricated pipe and soil, so that friction between the prefabricated pipe and the soil is reduced, disturbance on the soil is lowered, and thus road surface damage and building settlement are prevented.
Description
Technical field
The present invention is a kind of disturbance rejection jacking construction scheme, it is adaptable to the construction of the construction of Urban Underground underpass and other underground engineerings.
Background technology
Underpass often adopts Rectangular Tunnel, when taking the method construction of no-dig technique, uses rectangular pipe jacking machine driving, following closely, is a rectangle prefabricated pipe successively.
Most rectangle prefabricated pipe is by cast in concrete, and surface ratio is rougher.The soil friction peripheral with prefabricated pipe is very big.During constructing tunnel, prefabricated pipe constantly travels forward along with pipe jacking tunnelling machine, and the soil disturbance that prefabricated pipe is peripheral is very big.
Underpass often ratio is shallower, and the soil buried regions above passage is relatively thin, by easily producing after disturbance to subside and swell, makes ground road surface be damaged, or the matters of aggravation such as building settlement occur.
Summary of the invention
It is an object of the invention to provide a kind of disturbance rejection jacking construction scheme, by laying thin steel plate between prefabricated pipe and soil, reduce the friction of prefabricated pipe and soil, reduce the disturbance to soil, and then prevent road surface to be damaged and building settlement.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention:
Detailed description of the invention
As shown in Figure 1: disturbance rejection jacking construction scheme provided by the invention, including the strip steel laying apparatus arranged in push-bench, and to the locking device implementing to compress with coil of strip.
Strip steel laying apparatus is support band coil of strip 7 by hanger 6, and the head of strip steel passes through guide wheel 8, inserts between prefabricated pipe 9 and soil.Along with prefabricated pipe constantly travels forward, strip steel is just by being sent between prefabricated pipe and soil successively.
In order to prevent strip steel unwinding from opening, being provided with locking gear 3 in development machine, locking gear is by seat supports on development machine 1, and locking gear is provided with briquetting 5, and briquetting 5 is pressed on band coil of strip, prevents strip steel unwinding and opens.
Locking gear 3 is provided with counterweight 2, and band coil of strip, by the briquetting 5 above locking gear 3, is applied pressure by counterweight 2.
Having laid strip steel between prefabricated pipe and soil, strip steel separated, the friction between prefabricated pipe and soil converts the friction of prefabricated pipe and strip steel to.Owing to the surface of strip steel is very smooth, the friction of prefabricated pipe and strip steel reduces, and then reduces the disturbance to soil.
Along with prefabricated pipe extends the strip steel laid, the protection to the Zinc fractions above prefabricated pipe, it is therefore prevented that road surface is damaged, it is to avoid building settlement.
