Embodiment 1

[0029] A kind of caisson technology construction technology that the present invention adopts comprises the following steps:

[0030] Step 1) Site leveling;

[0031] Step 2) Measure and locate;

[0032] Step 3) Foundation pit excavation and erection of construction platforms and equipment;

[0033] Step 4) excavate the earth, put the jack group 3 into the pit;

[0034] Step 5) Continue digging and place the prefabricated concrete slab 2 on the upper end of the jack group 3 to wait for vertical adjustment, and set the verticality monitoring point 5 to be monitored by the computer monitoring system 6;

[0035] Step 6) Inject lubricating and water-stopping agent 1 around the foundation pit to reduce the displacement of the surrounding soil, reduce the friction between the concrete plate 2 and the soil, increase the sinking force of the concrete plate 2, and have the effect of water-stopping ;

[0036] Step 7) Adjust the jack group 3 to control the verticality of the concrete ...

Abstract

The invention relates to an open caisson construction technology, a jack set is placed into a foundation pit, a concrete plate is placed at the upper end of the jack set, and the periphery of the foundation pit is filled with a lubrication water-stop agent which has the functions of reducing displacement of peripheral soil, increasing concrete sinking power and stopping water; the jack set has the function of adjusting the perpendicularity; the blade foot has the cut soil sinkingfunction; a computer monitoring system monitors the perpendicularity of the open caisson in real time by a perpendicularity monitoring point. According to the open caisson construction technology, the problems that in the conventional construction technologies the sinking speed cannot be controlled, the peripheral sinking is large, damage to the peripheral environment is large, the perpendicularity adjustment is inconvenient and inflexible and the construction quality cannot be guaranteed are solved, the construction is easy, and the cost is saved.

Description

technical field [0001] The invention relates to a caisson construction technology, which is mainly used in the construction of bridge engineering, municipal engineering, water supply and drainage engineering, tunnel engineering and civil construction engineering. Background technique [0002] With the development of my country's engineering construction and social economy, urban land resources are gradually scarce, and the development of urban underground space has increasingly become the trend of urban development. Excavating and constructing large-depth underground spaces in densely built areas in the city center often faces the site Narrow and complex surrounding environment. In severe cases, it may cause the subsidence of the surrounding stratum, which will seriously affect the adjacent buildings. In contrast, the construction of caissons can better meet the characteristics of construction and meet the needs of construction. However, in the construction of caissons, it is...
