Integral rapid construction method for earthwork, ground mould and pile of manhole pile multi-pile cap

Abstract

The invention relates to an integrated quick construction method of an earthwork, an earth formwork and a pile for a multi-pile cap of a man-hole pile. After a foundation pit is dug, the pile cap earthwork is dug to near a preset pile cap soil-layer height mark according to the shape and the position of the preset pile cap to form a pile cap pit, then the construction of the man-hole pile and the construction of the pile cap earth formwork are made. By that the earthwork in the pile cap is directly dug during the construction of the earthwork in the foundation pit, the construction of the pile cap earth formwork can be made during or around the construction of the pile, thereby being capable of shortening the time limit of the construction. The preset pile cap soil-layer height mark accessory is directly dug during the construction of the earthwork, thereby avoiding the longer hollow pile concrete protection wall existing in the prior art, reducing the waste of the resource, and reducing the pollution to the natural environment.

Description

technical field [0001] The invention relates to a construction method for the integrated construction of multi-pile caps, ground models and piles for manual hole-digging piles in construction engineering, so as to speed up the construction process. Background technique [0002] In construction engineering, multi-pile caps are usually designed according to the bearing capacity of the caps. The multi-pile cap described in the present invention refers to the same load-bearing cap that needs to be jointly supported by multiple (including two piles) artificially excavated piles, and the multi-pile cap is hereinafter referred to as the cap for short. Such as figure 1 , 2 As shown in , 3, the traditional construction method usually includes the following construction steps when constructing such a cap: [0003] 1. Excavate the pile construction operation surface 101 that meets the predetermined manhole pile construction in the foundation pit 111. At this time, there is often no ...

AI Technical Summary

Problems solved by technology

[0009] 1. Because the operation surface 101 during pile construction is higher than the operation surface 102 during construction of the cap bottom cushion, and the pile core concrete 103 is lower, a longer empty concrete retaining wall 105 will be formed, resulting in waste of resources, and excavation, The chiseled empty concrete retaining wall will also pollute the environment

[0010] 2. During the construction of concrete cushion, ground beams, platform caps, etc., in the case of deep and small foundation pits, the amount of earthwork and molds in the caps is relatively large and the completed piles cannot be damaged. Waiting for the finished product, thus making it inconvenient to get off the car or dig the construction channel

[0011] 3. After the pile construction is completed, before the earthwork construction of the cap platform, and after the pile construction team and the structural construction team are handed over, the water around the manhole pile that has been rained during the pile construction may rise again, which is not conducive to the earthwork and groundwork of the cap platform. Construction of molds, etc.
