The invention discloses a technical method of a green sponge roof based on grass-planting boards, specifically: laying waterproof materials on the roof; laying spacer materials on the waterproof layer; then laying ecological grass-planting boards; Lay isolation filter material; bury the planting soil on the filter layer; sow the herb seeds into the planting soil above the grass-planting board, after watering and maintenance, the roof greening will be completed when the herb plants form their own ecological community, forming a green roof . The construction process of this green roof technology is simple and easy to operate. The grass-planting board is used as the drainage storage layer and the base surface for planting. Compared with the coarse sand filter layer and gravel (pebble, ceramsite) drainage layer of the traditional green roof, the construction The difficulty is much less, and the construction stability is high, so as to ensure the final construction quality and effect. The formed landscape is not only ecological but also beautiful.

The invention discloses concrete pumping equipment and an arm rest tail end vibration reduction method for a concrete pump truck. The concrete pumping equipment comprises a concrete conveying pipe and a gas charging system. The gas charging system comprises a pressure gas source (1) and a gas charging pipeline (2), the gas charging pipeline is connected with the pressure gas source and the concrete conveying pipe so as to charge pressure gas into a pipe cavity of the concrete conveying pipe. The pressure gas is creatively charged into the concrete conveying pipe through the gas charging system which is additionally arranged, so that the continuous gas is charged into the discontinuous size of concrete which is pumped discontinuously, and pumped media flow continuously; thus, pumping impact is reduced radically, and the purpose of reducing the tail end vibration of an arm rest is achieved; in addition, the pressure gas is charged, so that multiphase flows are formed inside the concrete conveying pipe, internal energy consumption among the multiphase flows is increased, and vibration is also relieved radically. Therefore, in the construction process of the concrete pump truck, the arm rest tail end displacement vibration can be reduced initiatively, and the construction stability of the concrete pump truck is improved.

The invention discloses a construction method of an elevator shaft operation platform. The construction method comprises the following steps that A, the operation platform is acquired, the operation platform comprises a top frame, a support frame and a diagonal bracing member, the support frame is provided with a bracket vertically arranged, and the top frame is further provided with a lifting lugfor lifting; a construction platform is hinged to the upper part of the top frame, and a height adjusting mechanism is arranged between the construction platform and the top frame; B, the operating platform is lifted to a completed elevator shaft through a tower crane, the bracket is located on a floor slab at an elevator shaft door to support the entire operation platform, the height adjusting mechanism is adjusted to enable the construction platform to be in a horizontal state, the installation of the operation platform is completed, and construction personnel carries out construction on the construction platform; C, after the construction is completed, the operating platform is lifted to an upper floor; and D, the steps B and C are repeated until the operation construction in the elevator shaft is completed. The construction method has the advantages of being able to reduce construction difficulty, improving the construction environment, improving construction stability and safetyand the like.
