Grouting type steel pipe pile and construction method thereof

Номер: CN0111636417A
Принадлежит:

The invention relates to a grouting type steel pipe pile and a construction method thereof and relates to the technical field of steel pipe pile construction. The problems that a steel pipe pile is constructed through a traditional down-the-hole hammer, the pile forming difficulty is high, and adaptability is poor are solved. The grouting type steel pipe pile comprises a steel pipe pile body formed by a steel pipe. Cement slurry and broken stone are fixed into the steel pipe pile body and the periphery of the steel pipe pile. The method comprises the following steps that firstly, a bottom sealing steel plate is installed; secondly, holing is carried out; thirdly, the steel pipe pile is constructed and stricken; fourthly, one-time grouting is carried out; fifthly, broken stone is thrown; sixthly, second-time grouting is carried out; and seventhly, a crown beam is welded. According to the steel pipe pile and the method, the cement slurry is injected into soil layers around a pile body uniformly ...

Plant salt stress tolerant protein and encoding gene and application thereof

Номер: CN0101386646B
Принадлежит:

The invention discloses a vegetable adversity resistant protein and a coding gene and application thereof. The vegetable adversity resistant protein is a protein having one of the following amino acid residue sequences: 1) the SEQ ID No. 2 amino acid residue sequence in a sequence table; and 2) a protein which has vegetable salt resistance and is obtained through replacing and/or deleting and/or adding one or a plurality of amino acid residues in and/or from and/or into the SEQ ID No. 2 amino acid residue sequence in the sequence table. Experiments show that the protein has high resistance tosalt and drought and the vegetable resistance to salt and drought can be improved through shifting coding genes of the protein into vegetables.
