Embodiment Construction

[0040] A construction method for digging underground pipe galleries and storage wells, such as Figure 1-5 shown, including the following steps:

[0041] Step 1: Level the site, measure and place the piles, and pour the concrete guide wall of the occlusal piles;

[0042] Step 2: Use a portable pile driver to construct a concrete occlusal pile composed of plain concrete water-stop piles, reinforced concrete support piles, and reinforced concrete load-bearing piles, which are used as concrete occlusal piles for the pipe gallery wall and the water storage well wall Concrete occlusal pile two 29, construct 4 pile diameters in the storage well again and be the reinforced concrete bearing column pile 2 of 80cm; The pile diameter of concrete bearing pile one 3 is 60cm, and the pile diameter of plain concrete water stop pile two 30, reinforced concrete support pile two 31, reinforced concrete bearing pile two 4 of reservoir well wall is 80cm;

[0043]Step 3: One week after the compl...

Abstract

The invention relates to a construction method for a subsurface excavated underground pipe rack and storage well. Construction of the pipe rack and storage well is conducted through a reverse construction method in a subsurface excavation manner, reinforced concrete bearing piles, plain concrete water stop piles and reinforced concrete support piles are engaged with one another to be used as the wall of the pipe rack and storage well, a water storage well is arranged at the bottom of a pipe rack to be used for flood prevention, water storage and water resource secondary utilization of seaside cities, and seasonal water in a soil layer can effectively seep and be discharged through water seepage holes formed in the wall. By means of the technical scheme, the world-class engineering problem of successfully implanting the pipe rack in the underground portion of an old city on the premise of less influencing the city road surface traffic is solved, the comprehensive structure of the underground pipe rack and storage well which is high in speed, low in manufacturing cost and short in period and is obtained through subsurface excavation is provided for the seaside city construction in China, and therefore the construction method has wide market prospects and social value.

Description

technical field [0001] The invention relates to the field of underground building construction, in particular to a construction method for digging underground pipe galleries and storage wells. Background technique [0002] The country has started the construction of underground pipe galleries in many cities. The underground pipe galleries are basically built below the roads in the cities. Although the three construction methods have less time to interfere with the surface roads, the cost is too high and the completion and delivery time is long. Therefore, open cut construction is basically adopted at present. When the underground pipe gallery adopts open cut construction, it takes at least half a year to occupy the urban roads, and even one to two years in densely populated urban areas. How to successfully implant the pipe gallery into the underground of the old urban area with dense surrounding buildings and vertical and horizontal traffic arterial roads has become a world...
