Embodiment Construction

[0031] see figure 1 The shown building pile foundation construction device of the present invention includes a working warehouse 1, an opening protection section 2, 6 all-steel casing expansion and contraction sections 3 and a lifting bracket 4.

[0032] Working warehouse 1 is in the shape of an inverted barrel. Working warehouse 1 is an important place for workers to safely operate in manual digging. Each set is equipped with one, and the design height is 2 meters so that the operator can work upright. The diameter of the manhole is 700 mm. The manhole 11 is provided with two semi-dome covers 12, which are normally in a closed state. In the internal work, as long as the operator pulls the rope connecting the top cover 12 in the working compartment 1, the rope will pass the pulley to the top cover 12. Pull upwards. In order to facilitate the lighting in the warehouse, two low-voltage lighting lamps 13 are arranged on the top plate, and two holes with a diameter of 5 cm are ar...

Abstract

The invention discloses a manually digging hole full-steel cylinder-wall protecting construction device for a building pile foundation and a construction method thereof. The device comprises a working chamber, an orifice protection joint, a full-steel cylinder protecting dilation joint and a lifting bracket, wherein the working chamber has an inverse barrel shape, the orifice protection joint is a T-shaped sleeve, and the full-steel cylinder protecting dilation joint is a cylinder which is formed by mutually screwing three steel templates. The construction method comprises the following steps: firstly, manually digging a hole, putting the working chamber into the hole, and then putting the orifice protection joint into the hole; secondly, putting the full-steel cylinder protecting dilation joint into the hole, screwing off a bolt to increase the diameter, making the full-steel cylinder protecting dilation joint support the wall of the hole, filling gaps by filling steel sheets, and downwards digging the hole and circularly putting the full-steel cylinder protecting dilation joint into the hole till digging to a designed depth; and screwing down the bolt for the down-most full-steel cylinder protecting dilation joint after finishing, lifting the full-steel cylinder protecting dilation joint out of the hole through the lifting of a winch, by inference, lifting all the full-steel cylinder protecting dilation joints out of the hole, finally withdrawing the working chamber, then putting the orifice protection joint into the hole, and pulling out the orifice protection joint when the pile foundation concrete is poured. The construction device and the construction method are safe to use and high in working efficiency.

Description

technical field [0001] The invention belongs to the technical field of building engineering, in particular to a building pile foundation construction device and a construction method thereof. Background technique [0002] Over the years, due to the fact that the safety of manual digging construction cannot be guaranteed, casualty accidents caused by manual digging have occurred frequently throughout the country, which has always been the biggest safety hazard in the manual digging construction process. In order to strengthen the needs of safe production, the manual excavation construction must adopt concrete retaining wall protection, that is, the concrete retaining wall must be excavated and drilled for safety protection. But there are still many problems in the current construction. [0003] First of all, there are hidden dangers in safety. In order to solve the potential safety hazards such as hole wall collapse and falling stones that may occur in manual digging, the t...
