Embodiment Construction

[0037] The following description is used to disclose the specific content of the present invention so that those skilled in the art can realize the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

[0038] The embodiment of the present invention is an operation platform for a rotary drilling rig on a soft soil foundation. To achieve the above purpose, the product mainly includes a cushion foundation 1 , a clay embankment 2 and a rigid road base 3 .

[0039] 1. Rigid road substrate

[0040] 1.1.1. Concrete structure

[0041] The rigid road base plate 3 for the rotary drilling rig on the soft soil foundation needs to have a certain thickness to meet the requirements of the soft foundation, and the thickness should be 30cm±5cm. On the one hand, if the thickness is too small, it is not enough to spread the stress of the track base of the rotary drilling rig above 100kPa to the weak f...

Abstract

The invention discloses an operation platform for a rotary drilling rig in a soft soil area and a use method. The operation platform is composed of three parts of a cushion foundation, a clay protection embankment, a rigid subgrade plate and the like. The rigid subgrade plate is made of prefabricated assembled concrete elements which are connected as a whole through PBL key type double-hinged connecting plates, built-in flow guiding pipes are embedded in the elements, and angle steel are arranged to reinforce the edges of the elements. The rigid subgrade plate is arranged on the cushion foundation, and the clay protection embankment is arranged around the rigid subgrade plate to form a temporary mud storage area with the rigid subgradeplate. The rigid subgrade plate effectively and evenlydistributes the weight of the rotary drilling rig to the soft foundation, thus bottom stress of the rigid subgrade plate meets the bearing capacity requirements of the soft ground, and meanwhile overall settlement of the operation platform is alleviated; and a mud circulation system composed of the built-in flow guiding pipes arranged in the rigid subgrade plate and a temporary mud pit can effectively solve the problem of repeated spillage and backflow of mud of rotary excavating hole forming process. The operation platform for the rotary drilling rig in the soft soil foundation and the use method have very remarkable economic and social benefits in municipal engineering of the soft soil area.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to an operating platform for a soft soil foundation rotary drilling rig and a use method thereof. Background technique [0002] With the increasing urbanization of our country and the steady increase of urban population, urban expressway has become an important means to solve urban traffic congestion. The common urban expressways in China all adopt "ground road + main line elevated", that is, the caps of the main line elevated are located in the central divider of the ground road. Usually, the construction scale of urban expressway is large, the number of bored piles is large, and the construction period is long. When the pile foundation involves rock-socketed layers, round gravel layers or pebble layers, the rotary drilling hole-forming process has a high economic advantage. [0003] The rotary drilling rig required for the rotary drilling process is very heavy. ...
