The utility model is described in detail below with reference to the drawings and the detailed description;
FIG. 1 is a flow chart of the reinforcing construction process of the deep and soft roadbed in the high water-bearing stratum.
FIG. 2 is a schematic diagram of a firmware structure according to the present invention.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained below by combining the specific drawings.
Referring to fig. 1, in the embodiment, when the ground fixing member is manufactured, a geotextile bag is sleeved in a rectangular rigid box or a rigid box with equal size, and in order to add certain rigidity to the ground fixing member, an internal constraint can be optionally added in the geotextile bag; filling a proper amount of materials which are easy to permeate water, such as broken stones or sands, and the like, into the geotextile bag, and also filling industrial solid wastes; transporting the sealed ground firmware to the position of the deep and weak roadbed of the high water-bearing stratum; and finally, laying steel plates and prepressing. According to the technology, a proper amount of material is filled in the square geotextile bag with enough rigidity, the friction force of the material is higher, and the tension action of the geotextile bag increases the friction force of the material, so that the compression resistance is increased, and the strength is enhanced.
Pressurization is applied over the ground fixture to dissipate the hyperstatic pore water pressure in the soft soil, thereby increasing the effective stress and ultimately increasing the strength of the soil. The ground firmware is flexible member, and the rigidity that can not be too big like the concrete member, the atress takes place to rotate.
Referring to fig. 2, the steps of the firmware are as follows:
(1) firstly, sleeving an outer package 1 in a rectangular rigid box or a rigid box with equal size, and optionally adding a constraint 2 inside and outside the outer package in order to increase certain rigidity for the ground firmware;
(2) filling a proper amount of water-permeable materials 3 such as broken stones or sands and the like into the interior of the ground firmware, and filling building waste residues or industrial solid wastes which do not contain chemical pollution;
(3) the ground fixing piece is closed.
The scheme for ensuring the tightness of the geotextile bags in the ground fixing piece and how to ensure that the ground fixing piece has certain rigidity is as follows:
(1) the outer packing material of the fastener is selected according to the condition of the high-water-content stratum, and in addition, the packing material has the effects of ageing resistance and ultraviolet resistance, so that the improved geotextile bag is adopted, and the black polypropylene material is added in the manufacturing process of the improved geotextile bag, so that the geotextile bag has the characteristics of economy and durability;
(2) selecting a weaving belt with the width of 10-15 centimeters for binding the improved geotextile bag;
(3) manufacturing the improved geotextile bag into a sleeve type, sewing four woven belts at the bottom of the improved geotextile bag, extending the woven belts out of the outer side of the bottom, and fastening the bag opening of the improved geotextile bag by using the woven belts after the materials are filled;
(4) the size of the improved geotextile bag is not suitable to be too large, and the side length is generally controlled to be 80-120 cm;
(5) the size of the materials filled into the improved geotextile bag is not suitable to be overlarge, and industrial solid wastes, building waste residues and the like are crushed to be below 5 cm.
