[0014] 1. On both sides of the pile hole of the large-tonnage anchor static pressure pile, according to the requirements of the drawing, 4 (8 in total) finished-rolled threaded steel bars with a diameter of 32mm are symmetrically pre-embedded or implanted as anchor rods, and the cap surface is exposed by 30cm.

[0015] 2. After the strength of the concrete meets the requirements of the pile pressure or the pull-out resistance of the implanted finished-rolled threaded steel bars meets the requirements, the finished-rolled threaded steel bars with a diameter of 32 mm (length 2 meters to 6 meters) consistent with the number of pre-embedded anchors will be passed through the special The connector is firmly connected with the pre-embedded fine-rolled threaded steel anchor rod.

[0016] 3. From the top of the fine-rolled threaded steel bar, penetrate the pressure pile reaction plate (the jack and the reaction plate are connected as one), M32 tool nuts, M32 fixing nuts, steel plates f...

Abstract

The invention relates to a large-tonnage anchor rod simple static-pressure-pile pressing frame. The large-tonnage anchor rod simple static-pressure-pile pressing frame is characterized in that a reinforced concrete pile bearing platform (10) serves as a fixing foundation, pre-buried anchor rods (12) are arranged in the reinforced concrete pile bearing platform (10), the lower portions of pile pressing frame twisted steel (8) are connected with the pre-buried anchor rods (12) through pre-buried anchor rod connectors (9), a top steel plate (2) is arranged on the upper portions of the pile pressing frame twisted steel (8) and fixed through top steel plate fixing nuts (3), an electric block (1) is fixed on the top steel plate (2), a pile pressing frame counter-force plate (5) is arranged below the top steel plate (2) and fixed on the pile pressing frame twisted steel (8) through pile pressing frame counter-force plate fixing nuts (4), an oil jack (6) is arranged below the pile pressing frame counter-force plate (5), and the lower portion of the oil jack (6) is pressed on a steel pipe (11) through a steel base plate (7). After being disassembled, the large-tonnage anchor rod simple static-pressure-pile pressing frame is light in weight, quite easy to transport and carry in site, convenient to install and rapid and convenient to operate.

Description

technical field [0001] The invention relates to a simple pile-pressing frame for a large-tonnage static-pressure anchor pile, in particular to a pile-pressing frame suitable for the construction of a large-tonnage static-pressure pile with a pile pressure up to 5000KN, which has the advantages of light equipment, easy operation, convenient disassembly and assembly, and economical cost , It is suitable for large-tonnage pile-pressing pile frames with various characteristics of various pile-pressing sites of existing buildings. Background technique [0002] The traditional large-tonnage anchor static pressure piles are all made of section steel. Because of their large size and heavy weight, they are not easy to transport and install on site, and the tonnage of the pressure piles generally does not exceed 3000KN. It is often necessary to cooperate with the construction of the pile pressure. Large-scale hoisting equipment such as cranes can complete the pile pressing constructio...
