| titleOfInvention | Construction method for in-situ reinforcing of high-pressure cement-chemical pulp compound grouting |
| abstract | The invention discloses a construction method for in-situ reinforcing of high-pressure cement-chemical pulp compound grouting, which is characterized by comprising the following steps: performing high-pressure cement grouting on a soft part of a to-be-processed foundation; performing fine cement grouting; and grouting a high-osmosis epoxy chemical pulp after the fine cement grouting is performed and the permeability rate of a pressurized water detecting hole section is less than or equal to 1Lu. According to the construction method provided by the invention, the non-uniformity of an osmotic coefficient of a grouted stratum is improved; the chemical pulp only can permeate into fine cracks or gaps of rock clay particles less than 0.1mm; the purposes of lithologic treatment for soil and modification for soft rock are achieved; according to the construction method provided by the invention, the continuous cement paste can be formed; a 'skeleton' is formed in a soft foundation; the effect of increasing the modulus of deformation of a processed stratum is obvious; the soft and broken foundation which is deeply embedded and low in osmosis property is subjected to in-situ solidification and reinforcement; and the mechanical demand of a large hydropower station dam on the foundation is met. |
