Mud treatment device for building pile foundation construction

Abstract

The invention provides a mud treatment device for building pile foundation construction. The mud treatment device comprises a sand pump for pumping mud and drilling slag out of a drilled hole, a clean water tank for storing clean water, a water pump, a sand and water mixing pipeline, a screen and a net rack, wherein the input end of the water pump is communicated with the clean water tank, so that clean water can be pumped; the position of the input end of the sand and water mixing pipeline is higher than that of the output end of the sand and water mixing pipeline, the output end of the sand pump and the output end of the water pump are both connected to the input end of the sand and water mixing pipeline; the screen is of a circular-arc-shaped structure, the input end of the screen is located below the output end of the sand and water mixing pipeline, the position of the input end of the screen is higher than that of the output end of the screen, and an included angle between the axis of the screen and the horizontal line is 20-30 degrees; the net frame comprises at least two diagonal rods, the upper end of each diagonal rod is fixed with the edge of the screen, and the lower end of each diagonal rod is connected to a vibrating plate. The med treatment device has the following benefit: automatic discharge of drilling slag is realized after mud separation.

Description

technical field [0001] The invention relates to a device used in pile foundation construction, in particular to a construction mud treatment device for pile foundation construction. Background technique [0002] With the development of the economy and the acceleration of urbanization, the construction industry is developing more and more rapidly, and more and more buildings are built on complex foundations. Pile foundation engineering has become one of the most commonly used forms of construction. For complex foundations such as soft foundations, block stones, or super-deep and super-large-diameter pile foundations, the mechanical mud retaining wall forming technology is used more and more as a mature technology during construction. In the prior art, during construction, a mud pool is set on the site plane for mixing mud or as a circulating mud pool. The mud index in the borehole is repeatedly measured along with the drilling footage, and the mud pump is used to replenish th...

Problems solved by technology

Although this system has achieved the separation of mud and drilled ballast to a certain extent, the disadvantages that still exist in this system are: 1) the system is provided with two filter sieve plates, and all filter sieve plates are arranged in the horizontal direction, although The filtering effect of the filter sieve plate is good, but it is difficult to remove the drilling ballast on the filter screen plate after the filtering operation is completed. The system is equipped with a screw conveyor for the drill ballast removed from the filter screen plate. Since the filter screen plate is located in the horizontal direction In fact, although the screw conveyor is inclined, only a small part of the drill ballast can enter the screw conveyor and be transported out. After a long time, the drill ballast will be deposited on the filter sieve plate, which hinders the subsequent mud filtration. Simultaneously, the phenomenon that the filter sieve plate will be damaged due to the large amount of drilling slag will occur, and the work of the screw conveyor will also consume more energy, which cannot meet the modern energy-saving and environmental protection requirements; 2) vibrators are set on the filter box of the system, thereby Realize the vibration of the whole filter box (including the filter sieve plate), but in order to increase the separation speed of mud and drill ballast, it is only necessary to vibrate the filter sieve plate, so a vibrator is installed on the entire filter box to make the filter box vibrate in the same way It takes a lot of energy, and the filter box will be damaged quickly if it vibrates together for a long time
