Third embodiment, the foundation pit vertical slope pier type retaining wall structure assembled by the ground firmware
In foundation pit engineering, retaining walls are built by piling up common soil bags to control deformation and displacement of foundation pit slopes. However, the geotextile bag has poor shape-keeping effect and low bearing capacity, the compactness of filling materials cannot be ensured, and the bag body has poor weather resistance, so that the safety and deformation control of the vertical side slope of the foundation pit cannot be ensured, but the ground fixing part 1 overcomes all the defects of the traditional geotextile bag.
Fig. 6 and 7 show a schematic cross-sectional view and a schematic plan view of the retaining wall 68 of the foundation pit vertical slope retaining member 1. as can be seen, this pier retaining wall 68 is a vertical enclosure 6 adjacent to the foundation pit and is segmented along the side line of the enclosure to replace the horizontal support and gravity retaining wall of the conventional foundation pit retaining structure.
In order to provide sufficient horizontal force to the pit vertical envelope 6, the pier retaining wall 68 is attached to the vertical envelope 6 over a width, and occupies a length and height that may be embedded below the pit floor 66 if necessary. In addition, the pier-type retaining wall 68 is constructed in a stepped manner with a large lower part and a small upper part, and the upper plane is positioned below the crown beams 65, so that a space is provided for erecting a horizontal structure truss between two adjacent pier-type retaining walls 68, and the horizontal structure truss has large horizontal rigidity and supporting resistance.
The pier-type retaining wall 68 is arranged on the inner side of the soft soil foundation pit, a foundation trench needs to be excavated in advance, and the foundation trench needs to be protected and supported. A foundation trench enclosure structure consisting of vertical steel sheet piles 61, profile steel purlins and profile steel supports is arranged, as shown in figure 8, under the shielding of the enclosure structure, a foundation trench is excavated, and one side of the foundation trench facing the inside of a foundation pit can be processed by a grooving slope surface 67. After the pier-type retaining wall 68 of the ground fixing member 1 is paved, the steel sheet pile 61, the surrounding purlin and the support for protecting and excavating are removed, and the steel sheet pile, the surrounding purlin and the support are repeatedly used for installing the next pier-type retaining wall.
Example four, the bedding course and the bearing platform of the building bottom plate assembled by the ground firmware excavate the retaining wall and the moulding bed
Fig. 9 shows a bedding course 8 of a building floor using a flooring 1, which can replace a conventional concrete bedding course, does not require maintenance, can endure rolling by construction machinery, and simultaneously provides a passive resistance of foundation soil in real time, and seals foundation soil and prevents the foundation soil from rising. After the foundation pit is dug in place and leveled, the ground fixing members 1 are laid flat and pressed to form a conical body 53 on the ground fixing members 1 and the ground surface 66, and then the interconnecting rings 16 between the ground fixing members 1 are connected to form a whole.
Fig. 10 shows a retaining wall and a forming die arranged for excavating a building bearing platform and a water collecting well, which are built by adopting a ground fixing piece 1. After the bottom surface 81 of a bearing platform or a water collecting well is excavated, the wall body is built by the ground fasteners 1, and meanwhile, the interconnection rings 16 among the ground fasteners 1 are connected by the interconnection connecting pieces 31 to form a whole body, so that the traditional brick moulding bed or the prefabricated concrete retaining wall can be replaced.

The assembled type ground firmware revetment and bedding structure and the laying method thereof of claim 1, wherein the filling material is sand, gravel, sandy soil, clay containing sand, construction residue soil, steel slag, sea sand, etc.; when the filling material is fluid solidified soil, it is made up by adding soil hardening agent into soft soil and mixing them.
6. The assembled type ground firmware revetment and bedding structure and the laying method thereof of claim 1, wherein the pre-buried mounting hole is located at the center of the plane of the ground firmware or at a corresponding position for mounting a hanging nail.
7. The fabricated flooring revetment and underlayment structure of claim 1, wherein a plastic drainage plate is disposed inside the flooring, and one end of the drainage plate is connected to the rigid bladder of the flooring to drain moisture from the filler of the reinforced flooring.
8. The fabricated flooring revetment and underlayment structure of claim 1, wherein the hanging nails are comprised of nails made of steel bars and nails made of non-metallic material, and are installed at the center of the rigid bladder, at the interface or at the junction of a plurality of flooring members.
9. The assembled type ground fixing piece revetment and bedding structure and method of claim 1, wherein the filling material in the ground fixing piece provides nutrients and air permeability for plant growth, and the plants are moved in and out through the woven gaps of the stiff bag material and rooted and fixed.
10. A laying method of an assembly type ground firmware revetment and a cushion structure is characterized by comprising the following steps:
firstly, leveling and compacting a slope surface and a platform needing slope protection;
secondly, laying a layer of waterproof geotextile on the flattened and compacted platform and slope surface
Thirdly, paving the ground firmware continuously from the bottom surface to the top;
furthermore, slope protection structures need to be laid layer by layer on the slope excavated layer by layer. Before laying, a row of hanging nails are arranged along the surface of the mounting starting point so as to support the ground firmware to prevent the ground firmware from sliding downwards.
Step four, when each piece of ground fixing piece is paved, the ground fixing piece is pressurized along the direction vertical to the slope surface, the pressure is transmitted through the ground fixing piece to increase the compactness of the slope soil body, and meanwhile, a protruding conical soil body is formed on the slope surface to increase the frictional resistance between the ground fixing piece and the slope surface;
fifthly, mounting hanging nails along the middle hole and the adjacent joint of the ground fastener;
and sixthly, after paving, connecting certain intervals along the intersection of the ground firmware to set a water drain pipe.
