【発明の詳細な説明】
本発明は建造物が存する所の地盤の圧密沈下促進装置に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for promoting consolidation settlement of the ground where a building exists.
従来建造物を建てる個所の地盤中に軟弱な圧密層が存在
する場合に建造物の施工前に前記個所に盛土をして地盤
に荷重をかけ強制的に圧密沈下させたり又は前記個所に
デープウエル或いはクエルボイント等の井戸を設は該井
戸より水な抜いて圧密沈下′jkさせているが、建造物
の地の除去を又後者にあっては井戸の撤去をしなければ
ならず手間がかかると共に強制的に圧密沈下させる穴め
に時間的に制約される欠点があった。Conventionally, when there is a soft consolidation layer in the ground at the location where a building is being built, it is necessary to fill the area with embankment and apply a load to the ground to force the consolidation settlement before construction of the building, or to install a deep well or a layer in the area. When a well such as a quellboint is constructed, water is drained from the well and the soil is consolidated, but in the latter case, the ground for the building must be removed, and in the latter case, the well must be removed, which is time-consuming and difficult. The disadvantage was that the holes were forced to settle due to consolidation, which limited the time available.
本発明はこれらの欠点を排除した圧密沈下促進装置を提
供することを目的とするもので、その特、徴とするとこ

け。The object of the present invention is to provide a consolidation settlement promotion device that eliminates these drawbacks. A water pumping pipe is provided to connect the lower ends of these wells and a pump installed on the ground on the side of the structure.
前記建造物の竣工後においても揚水を可能としたことに
ある。It is possible to pump water even after the construction of the building is completed.
以下本発明の1実施例を図面に従って説明する。An embodiment of the present invention will be described below with reference to the drawings.

4)...From (4), water is pumped up and the ground (1) is consolidated and settled while the construction work of the upper building is carried out. and the building (
Pumping water will continue as necessary even after the completion of 2).

の修正が可能である。Therefore, sufficient consolidation settlement can be achieved without being limited by time as in the conventional case. When uneven subsidence occurs in the ground (1), open only the pulp (7) of the branch pipe (5a) of the well (4) in the concave area where the amount of subsidence is small, and release the other pulp (1). 7) It is possible to correct uneven subsidence by closing and pumping water intensively.

It has the effect of allowing the consolidation settling action to continue for any desired period of time until it occurs.
