Strong drainage pump for soft foundation treatment

Abstract

The invention relates to a strong drainage pump for soft foundation treatment. The strong drainage pump comprises a base, a motor arranged on the base, a pump housing and an impeller arranged in the pump housing, wherein the impeller is coaxially fixedly provided with a pump shaft, a fixing disc I and a fixing disc II are separately coaxially arranged on the pump shaft and an output shaft of the motor, multiple groups of limiting holes are separately correspondingly formed in the fixing disc I and the fixing disc II, nylon bars are inserted into the corresponding limiting holes of the fixing disc I and the fixing disc II, the nylon bars are parallel with the pump shaft, and limiting components for limiting the nylon bars are further arranged in the limiting holes. The strong drainage pump has the advantages that when blockage occurs, the connection of the motor and the pump shaft is cut off, and the motor is protected from damage.

Description

technical field [0001] The invention relates to the technical field of soft ground treatment, in particular to a strong discharge pump for soft ground treatment. Background technique [0002] At present, if the foundation is not strong enough before the construction, in order to prevent accidents such as the instability of the building caused by the subsidence and cracking of the foundation after the construction, it is necessary to deal with the soft foundation to make the settlement become strong enough to improve the consolidation and stability of the soft foundation According to the design requirements, this process is called soft foundation treatment. [0003] Existing authorized announcement number is that the Chinese patent of CN204691673U discloses a kind of soft foundation mud protection rotary drilling, comprises rotary drilling rig, steel casing and mud circulation system, and described mast top is handed over guide plate and pulley block, and described The top o...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: the above-mentioned pump shaft is coaxially connected with the output shaft of the motor through a coupling, so that the motor drives the pump shaft to drive the impeller to rotate to realize the delivery work of the mud pump; and in the working environment, Because the mud pump discharges the mud in the soft foundation, during the process of conveying the mud, there is a great probability that the stones in the mud will be sucked into the pump casing, and the stones will easily block the impeller, so that the pump casing will Blockage phenomenon; when the pump casing is blocked, the motor is still working, driving the pump shaft to rotate, resulting in increased load on the motor, which is likely to cause damage to the motor
