Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contribution as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.

[0031] Such as figure 1 Shown, a kind of rotary drilling rig hole-forming construction method that adopts chemical polymer mud retaining wall, comprises the following steps:

[0032] S1: Site leveling: Before construction, the site should be leveled and rolled according to the layout of the site to ensure that the foundation has sufficient bearing capacity to meet the driving needs of rotary drilling rigs and slag transport vehicles. Surrounding the pile position is completed at...

Abstract

The invention discloses a drilling construction method of a rotary drilling rig using a chemical polymer mud wall protection, comprising the following steps: S1: leveling the site; S2: setting a mud pool and a mud storage area, and preparing the chemical polymer mud; S3: piles Stake-out; S4: Drilling in place with rotary drilling rig; S5: Fabrication and embedding of casing and filling with chemical polymer mud; S6: Drilling and hole cleaning with rotary drilling machine. Compared with the prior art, the present invention provides a drilling construction method using a rotary drilling rig using chemical polymer mud to protect the wall, which has a short time for preparing mud and is convenient to use; It can reduce the amount of rotary excavation and concrete pouring, saving materials and mechanical shift costs; the slurry of the mud has a low sand content, can be cleaned by itself, and can be separated from the concrete by itself; the mud is non-polluting, does not produce waste mud, and can be recycled .

Description

technical field [0001] The invention relates to a drilling technology, in particular to a hole-forming construction method of a rotary drilling rig using chemical polymer mud wall protection. Background technique [0002] In the construction of bored piles in my country, bentonite mud wall protection is traditionally used, and rotary drilling or percussion drilling is used to drill holes. This process has low work efficiency, large amount of mud materials, high cost, large land occupation and serious pollution. In order to overcome these disadvantages, around 2006, the construction technology of chemical polymer mud retaining wall rotary drilling and drilling was introduced from the United States to China, and after digestion and absorption, it began to be used in engineering practice. The advantages of precise control, low noise, low pollution, convenient moving and positioning, and small construction area greatly improve the work efficiency of bored piles, reduce engineeri...
