The invention provides grouting slurry for reinforcing the tunnel face of a jacking culvert of a fine-sand layer and a grouting method. When the jacking frame culvert is reinforced by a pipe curtain and the tunnel face needs to keep self-stabilization at certain slope ratio, the diluted water glass and prepared calcium chloride solution are sequentially adopted for horizontal grouting reinforcement by a modified perforated-pipe grouting technology; and the unconfined compressive strength of the reinforced soil body can reach 100-500kPa, and the slope ratio required by the blade feet of the jacking culvert can be realized. Compared with the reinforcement by chemical slurry and high-pressure jet grouting, the grouting method is safe and stable; compared with the reinforcement by superfine cement grouting, the spreading range is large, the strength after reinforcement can meet the requirement on slope ratio stability, the excavation is easy, the construction is convenient, and the construction cost is reduced by more than half; meanwhile, by adopting the grouting technology provided by the invention, sectional grouting can be realized, the pipeline is not blocked easily, and an aim of dominant permeation of slurry in the dense fine-sand layer is achieved; and a slurry plug is not arranged at the lower end but the upper part, the grouting range is expanded, and the grouting effect is relatively good.

The invention discloses a method of planting lotus root. The method of planting the lotus root comprises the following steps of (1) selection of a lotus root field; (2) construction of a lotus root pond; (3) selection and processing of lotus seeds; (4) planting; (5) field managing: A, germination period; B, vigorous growth period; C, lotus root growth period; (6) water management; and (7) harvesting. The method of planting the lotus root is simple and easy to implement and can significantly increase the yield of the lotus root; the lotus root obtained by using the method is crisp and tender and has lots of moisture and good taste; by using a lotus root cultivation substrate, the application of chemical fertilizers is significantly reduced, the quality of the lotus root is effectively improved, the cost is reduced, and at the same time, the harm to the environment is reduced. According to the lotus root cultivation substrate, through the reasonable addition of bone powder and eggshell powder, phosphorus can be effectively supplemented in original soil; through the addition of green manure, nitrogen fertilizer and potash fertilizer are supplemented; the addition of vermiculite in thelotus root cultivation substrate can increase the permeability of the substrate, is conducive to the growth of the lotus root, and at the same time facilitates the digging out of the lotus root in the later period.

The invention discloses a stump rapidly removing method. The stump rapidly removing method comprises the following steps of (1) preparing stump removing materials; (2) applying the stump removing materials onto the cross section of a stump; (3) 5-7 days later, applying the stump removing materials onto the cross section of the stump again; (4) after the root of the stump rots, digging up the stump. The stump with the stump removing materials can rot and be easy to dig up and accordingly can be rapidly removed; every stump can be removed within 15-20 min, while stump removing in the prior art requires 30-40 min.

The invention provides a building wall body 3D printing method. A 3D printing sprayer head is used for printing a main wall body. When a pre-opening position of the main wall body begins to be printed, a supporting wall is printed in the pre-opening position of the main wall body with materials easy to dig out. After printing of the main wall body is finished, the supporting wall is dug out through a digging tool. The invention further provides building 3D printing equipment supporting the building wall body 3D printing method. The supporting wall is arranged in the pre-opening position, the printing materials of the supporting wall are easy to dig out later, the supporting wall has a supporting function in the printing process of the wall body, and after printing is finished, the digging tool can be used for directly digging out the supporting wall portion. The building wall body 3D printing method is convenient and rapid to operate, is low in cost, lowers the construction cost and greatly improves the construction progress. In addition, coloring pigments convenient to differentiate are added into the printing materials of the supporting wall, and thus the digging boundary can be rapidly determined in digging operation, and the construction speed is improved.

The invention discloses a stepped supporting method for a soft soil foundation pit. The method is characterized by comprising the steps that a, original ground natural unprotected open cut excavationis performed to from a first-stage platform, and first-stage steel sheet piles are vertically inserted in the circumferential direction of the foundation pit on the first-stage platform; b, inward excavation is performed continuously from the inner side faces of the first-stage steel sheet piles to form a construction platform, and a stirring pile drilling machine is controlled to construct stirring piles on the construction platform in a mode that the upper portion is hollow and the lower portion is solid; c, whole excavation is carried out from the outside to the inside in sequence on the construction platform, so that the hollow portions above the solid portions of all stages of the stirring piles are excavated to form the platforms, and the steel sheet piles are vertically inserted inthe positions, close to the solid piles, of the outer sides of all the platforms until excavation is performed to be flush with the elevation of the foundation pit. The stepped supporting method for the soft soil foundation pit has the advantages that firstly excavation is carried out to form the construction platform, the construction platform and the stirring piles of which the lower portions have hollow portions make the effective pile length can reach a deeper soft soil treatment range, and the requirements for stable supporting of the 10-meter-deep foundation pit are achieved.
