Vibratory hammer device and shaking press type pile body construction method adopting same

Abstract

The invention discloses a vibratory hammer device. The device comprises a support, a vibratory hammer, a second pulley component, a winding plant and a balancing weight, wherein a first pulley component is installed on the support, the first end of the vibratory hammer is connected with the first pulley component, and the second end of the vibratory hammer is provided with a fixing structure used for fixing an inner pipe and an outer pipe; the second pulley component is installed on the support, the winding plant is installed on the support and connected with the vibratory hammer through the second pulley component and can apply a vertically downward force to the vibratory hammer, and the balancing weight is detachably connected to the vibratory hammer. In this way, construction noise is low, construction efficiency is high, and the dead weight of a hammer body can be adjusted flexibly to meet the requirement for pile forming. The invention further discloses a shaking press type pile body construction method adopting the vibratory hammer device.

Description

technical field [0001] The invention relates to equipment and a construction method for building foundation pile construction, in particular to vibratory hammer equipment and a vibratory pressure pile construction method using the vibratory hammer equipment. Background technique [0002] At present, there are a variety of construction methods for building piles and construction equipment used in the construction method in the prior art. These construction methods and equipment also have their own advantages and disadvantages. For example, when making immersed pipe grouting piles, hammering can be used There are two methods of immersed tube and vibrating immersed tube. The former is mostly used for general cohesive soil, silty soil, sandy soil and artificial filled soil foundation. The latter can also be used for slightly dense and medium dense gravel soil foundations in addition to the above scope. . The way of hammering the immersed tube will produce a lot of noise, especi...

Problems solved by technology

However, the vibrating pipe sinking method used in the prior art is used to make cast-in-situ piles. Vibratory hammer equipment is used to connect the hammer body with the inner or outer pipe used to form the pile hole, and the inner and outer pipes are sunk by vibration. to form pile holes; for environments with relatively dense soil, in order to ensure the construction progress, the working power of the vibratory hammer is usually increased to form pile holes; Dense, after the concrete is poured, the speed of forming the enlarged head of the pile bottom only by using vibratory hammer vibration pressure is relatively slow. At this time, if the vibratory hammer equipment with higher power is to be replaced, this may lead to higher cost of construction equipment. In addition, re-erection Mechanical equipment will also be more difficult. Even if the hammer body of a vibratory hammer with a heavier weight is replaced, it is very likely that it does not meet the installation conditions and may cause installation accidents.

Furthermore, the weight of the equipment in the prior art is determined once the hammer body is selected. If it is required to use different hammer body self-weights to meet the pile-forming requirements when vibrating into piles, it can only be replaced by replacing the hammer with the corresponding quality. body to achieve, so that the construction cost will also increase
