Rapid forming construction method for underground water collecting pit

Abstract

The invention provides a rapid forming construction method for an underground water collecting pit. The rapid forming construction method is characterized by comprising the following steps: a, manufacturing a forming mould box (8), namely, taking a steel plate with the thickness being greater than or equal to 8mm according to the size and depth of the underground water collecting pit, and cuttingthe steel plate to obtain one bottom plate (3) for the forming mould box, two long side walls (2) for the forming mould box, and two short side walls (1) for the forming mould box; and b, placing theforming mould box, namely, completely excavating the underground water collecting pit by adopting an excavator, completely pumping water in the underground water collecting pit by adopting a water pump, hoisting the manufactured forming mould box into the underground water collecting pit by adopting a crane, after positioning, rapidly carrying out concrete filling for the peripheral side walls ofthe forming mould box, after final setting of concrete, detaching the forming mould box, and thus the underground water collecting pit is formed. The rapid forming construction method has the advantages that the forming mould box is simple in structure and convenient to manufacture, the water collecting pit is rapidly formed, the labor efficiency is improved, compared with a shoring method, the method provided by the invention has the advantages that the construction cost is saved, the construction is safe, the safety risk is reduced, the forming mould box can be recycled, and the engineeringcost is reduced.

Description

technical field [0001] The invention relates to a construction method for forming an underground sump, in particular to a rapid forming construction method for an underground sump. Background technique [0002] In building construction, underground buildings are generally designed with sump pits, and the buried depth is relatively deep, so it is not easy to form when the foundation pit is excavated. Especially in the case of complex geology and abundant groundwater, it is difficult to form and construct sump pits. Two methods of construction are routinely adopted: the support method and the counter-model method. The support method needs to support the sump with stirring piles before excavation. Although this method can ensure the safety of later construction, the construction cost is extremely high; Set up the reverse form and finally pour the concrete into shape, the time requirement is tight, it is cumbersome, laborious, and has a high safety risk. [0003] Therefore th...

Problems solved by technology

The support method needs to support the sump with stirring piles before excavation. Although this method can ensure the safety of later construction, the construction cost is extremely high; Set up the counter-form and finally pour the concrete into shape, the time requirement is tight, it is more troublesome, laborious, and has a great safety risk

[0003] Therefore there is above-mentioned inconvenience and problem in known underground sump forming construction method
