Referring to fig. 1-2, the present invention provides a landscape architecture foundation with soft ground, which comprises a first grouting hole 1, a second grouting hole 2 and a rectangular concrete block 3. The rectangular concrete block 3 is arranged on the ground surface, and the top surface of the rectangular concrete block 3 is provided with a first guide hole 31 and a second guide hole 32 for guiding the drilling feeding direction. First guiding hole 31 sets up vertically, second guiding hole 32 slope sets up, second guiding hole 32 sets up two at least, two second guiding hole 32 extends to the relative both sides of rectangle concrete block 3 respectively. First injected hole 1 and second injected hole 2 are all seted up in the loose stratum, first injected hole 1 sets up the direction and 31 axial unanimity and communicate with first guiding hole 31, second injected hole 2 sets up the direction and 32 axial unanimity and communicate with second guiding hole 32, specifically, first injected

hole

1 and 2 diameters of second injected hole are 30~50mm, and the degree of depth is 1~1.5 m. During construction, the rectangular concrete block 3 is firstly placed on the ground surface planned by the landscape structure to be built, the first grouting hole 1 and the second grouting hole 2 are obtained by drilling or inserting holes in a soft stratum below the concrete block 3 along the guide hole on the rectangular concrete block 3 by adopting a twist drill or a steel needle, cement mortar is injected into the grouting holes after the drilling or inserting holes are finished, and the cement mortar is infiltrated into the loose soil layer and solidified with soil particles, so that the loose soil is solidified to improve the bearing strength of the soil, the cost is low, and the construction period is short. Rectangular concrete piece 3 is mainly in the construction location slip casting hole position and drilling guide effect, can tear away the used repeatedly after accomplishing the slip casting, also can pour integrative platform base so that follow-up construction with the slip casting hole. The second grouting holes 2 which are obliquely arranged are constructed around the first grouting holes 1 which are vertically arranged, so that soil is loosened and solidified below and around the rectangular concrete blocks 3, and the supporting area of the landscape structure foundation is increased.

As a further improvement to the above scheme, please refer to fig. 3, a plurality of rectangular concrete blocks 3 are provided, and a plurality of rectangular concrete blocks 3 are arranged at intervals, specifically, the side length of a rectangular concrete block 3 is 400-. Preferably, the second guiding holes 32 are slotted holes, so that two second grouting holes 2 which are oppositely arranged in two adjacent rectangular concrete blocks 3 are arranged in a staggered manner, namely, the two grouting holes are not interfered and communicated with each other, and the phenomenon that the grouting effect is influenced due to the fact that the holes collapse when the two second grouting holes 2 are communicated with each other in a crossed manner during drilling is avoided. In one embodiment, there is one first guide hole 31, and the first guide hole 31 is disposed at the geometric center of the top surface of the rectangular concrete block 3. In another embodiment, there are four first guiding holes 31, four first guiding holes 31 are disposed at four corners of the top surface of the rectangular concrete block 3, and a plurality of grouting holes are densely disposed below one rectangular concrete block 3 to greatly increase the bearing capacity of the soil layer, so that the soil layer can provide better supporting force when the foundation is constructed above the rectangular concrete block 3.

As a further improvement to the above scheme, a first grouting anchor rod is arranged in the first grouting hole 1, and the top end of the first grouting anchor rod is connected with the rectangular concrete block 3. And a second grouting anchor rod is arranged in the second grouting hole 2, and the top end of the second grouting anchor rod is connected with the rectangular concrete block 3. The grouting anchor rod is used as a skeleton of cement mortar, and the bearing capacity of a soft soil layer is further improved. Obviously, the grouting anchor rod can be directly arranged.

As a further improvement to the above scheme, please refer to fig. 2, two opposite sides of the rectangular concrete block 3 are provided with wing plates 33. Referring to fig. 4, during construction, two parallel temporary support beams 4 are firstly erected on the ground surface planned for building a landscape structure and are calibrated horizontally, and the temporary support beams 4 are preferably section steel; specifically, a self-advancing anchor rod 5 is vertically drilled at each of two ends of a temporary support beam 4, the self-advancing anchor rod 5 penetrates through the temporary support beam 4, fastening nuts in threaded connection with the self-advancing anchor rods 5 are arranged on the top surface and the bottom surface of the temporary support beam 4, horizontal calibration work of the temporary support beam 4 is achieved by adjusting the fastening nuts, and the fastening nuts at the bottom support the temporary support beam 4; when the soft stratum is shallow (the thickness is less than 5 m), the self-advancing anchor rod 5 needs to be nailed into the old soil layer to provide stable support for the temporary support beam 4, and when the soft stratum is deep (the thickness is more than 5 m), the self-advancing anchor rod 5 needs to be nailed into the old soil layer for 3-5m to provide stable support for the temporary support beam; after the two parallel temporary support beams 4 are horizontally calibrated, the rectangular concrete block 3 is placed between the temporary support beams 4, namely the bottom surfaces of the wing plates 33 are abutted against the top surfaces of the temporary support beams 4; after grouting is completed, the temporary support beam 4 and the self-advancing anchor rod 5 are removed for reuse. The design of the temporary supporting beam 4 ensures that the layout of the rectangular concrete blocks 3 is standardized and accurate, the operation is simple, the construction quality is high, and the work efficiency is short.
