Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method suitable for embedding deep pile caps. Background Art

[0002] During the construction of highway projects, housing projects, and railway projects, there will be pile leakage or pedestal hanging near steep slopes and cliffs, which will cause the project to be unable to be constructed normally. Traditional methods mostly use earth filling platforms for construction, which is not only time-consuming and labor-intensive, but also increases construction costs. Of course, traditional construction methods also have the weakness of being unable to effectively treat steep slopes. Therefore, it is particularly necessary to design a construction method suitable for deep pile pedestal embedding. Summary of the invention

[0003] The purpose of the present invention is to provide a construction method suitable for deep pile cap embedding to solve the above-mentioned deficiencies of the prior art.

[0004] In order to achieve the above object, the present invention provides the following technical solution: a construction method suitable for deep pile cap embedding, the steps are as follows:

[0005] Step 1: After clearing the site, first carry out vertical anchor construction and complete relevant inspections and acceptance;

[0006] Step 2: After step 1 is completed, the bottom horizontal steel reinforcement mesh is constructed, and inspection and acceptance are carried out. The bottom horizontal steel reinforcement mesh is set in multiple layers;

[0007] Step 3: While carrying out step 2, locate the position of the pile foundation construction, and pre-bury the pile foundation positioning casing to position the pile foundation. The pile foundation positioning casing is reinforced and fixed by multiple positioning frames, and the pile foundation positioning casing is buried at least 200mm into the original ground;

[0008] Step 4: After completing step 3, the formwork is installed. After the formwork installation is accepted, the rubble concrete construction is carried out. The rubble concrete construction is a stage-by-stage construction from top to bottom, and the side facing the air is stepped inward from bottom to top; the pile foundation positioning casing is connected layer by layer with the lifting of the rubble concrete, and the full welding construction process is adopted at the joint of the pile foundation positioning casing;

[0009] Step 5: After completing step 4, repeat the above steps until the bottom surface of the pedestal, where the bottom horizontal steel reinforcement mesh is only in the lower structure;

[0010] Step 6: After completing step 5, the pile foundation is constructed, and the pile foundation is located in the pile foundation positioning casing;

[0011] Step 7: After the above steps are completed, the last step is to carry out the construction, which is the foundation construction.

[0012] Preferably, the pile foundation positioning casing is higher than the underlying slab stone concrete surface layer by more than 400 mm to facilitate the heightening construction of the pile foundation positioning casing.

[0013] Beneficial effects: The present invention solves the problem that part of the pile foundation of the pedestal is suspended outside and cannot be handled near steep slopes and cliffs, effectively improves the construction quality and construction progress, and solves the weakness of the traditional construction that the steep slope cannot be effectively treated.

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Those skilled in the art will understand that the following examples are only used to illustrate the present invention and should not be considered to limit the scope of the present invention. If no specific technology, connection relationship or condition is specified in the examples, the technology, connection relationship, condition described in the literature in the field or the product specification is used. If the manufacturer of the materials, instruments or equipment used is not specified, they are all conventional products that can be purchased.

[0020] like Figure 1-3 As shown, the present invention provides a construction method suitable for deep pile cap embedding, the steps are as follows:

[0021] Step 1: After clearing the site, first carry out the construction of vertical anchor rods 1 (or pipe sheds), and complete relevant inspections and acceptance;

[0022] Step 2: After step 1 is completed, the bottom horizontal steel reinforcement mesh 2 is constructed, and inspection and acceptance are carried out. The bottom horizontal steel reinforcement mesh 2 is set in multiple layers;

[0023] Step 3: While carrying out step 2, locate the position of the pile foundation construction, and pre-embed the pile foundation positioning casing 4 to position the pile foundation 5. The pile foundation positioning casing 4 is reinforced and fixed in place by a plurality of positioning frames 6, such as Figure 2 As shown, the pile foundation positioning casing 4 is buried at least 200 mm into the original ground;

[0024] Step 4: After completing step 3, the formwork is installed (the formwork is installed on the outer side of the position to be embedded). After the formwork installation is accepted, the slab stone concrete 3 is constructed (the slab stone concrete 3 is poured in layers). The slab stone concrete 3 is constructed in stages from top to bottom, and the side facing the air from bottom to top is stepped inward; the pile foundation positioning casing 4 is connected layer by layer as the slab stone concrete 3 is lifted, and the joints of the pile foundation positioning casing 4 are fully welded.

[0025] Step 5: After completing step 4, repeat the above steps until the bottom surface of the pedestal, wherein the bottom horizontal steel reinforcement mesh 2 is only in the lower structure;

[0026] Step 6: After completing step 5, the pile foundation 5 operation is carried out. The operation construction includes pile foundation construction, detection, breaking and other processes. The pile foundation 5 is located in the pile foundation positioning casing 4 for construction. The construction method is as follows: Figure 3 As shown;
