Soft soil foundation strengthening method and composite pile foundation construction method comprising same
The invention discloses a soft soil foundation strengthening method and a composite pile foundation construction method comprising the same. A weak bearing layer is filled and mixed with adhesive and/or a curing agent at a preset depth to form an integral gapless strengthening area. According to the soft soil foundation strengthening method, the weak bearing layer is filled and mixed with the adhesive and/or the curing agent at the preset depth to form the integral gapless strengthening area, so that the integral bearing capacity of a soft soil foundation is improved. The invention further discloses a construction method of a composite pile foundation carried out on the integral gapless strengthening area. The soft soil foundation strengthening method can be used for solidifying shallow soil close to the ground and can also be used for solidifying deep soil under the ground, can be used for solidifying soil in a certain area in the middle of the weak bearing layer, and can also be usedfor solidifying soil above a natural bearing layer; when the soft soil foundation strengthening method is used for a non-pile foundation, the foundation bearing capacity can be improved, and the applicability of the soft soil foundation is improved; and when the soft soil foundation strengthening method is used for a pile foundation, the pile body length can be shortened, the deep pile driving difficulty can be reduced, the foundation engineering cost is reduced, and the soft soil foundation strengthening method is easy to use widely.
本发明公开了一种软土地基强化方法及其复合桩基施工方法，在弱承载层预定深度填充混合有胶粘剂和/或固化剂以形成整体式无间隙加固区。本发明提供的软土地基强化方法通过在弱承载层预定深度填充混合有胶粘剂和/或固化剂以形成整体式无间隙加固区，提高软土地基的整体承载力。本发明还公开了在整体式无间隙加固区上进行复合桩基的施工方法。软土地基强化方法既能用于接近地面的浅层土体固化，又能用于地面以下较深处土体固化；既能用于弱承载层中间的定区土体固化，又能用于自然持力层上方土体固化。用于非桩基础，可以提高基础承载力，提高软土地基的适用性；用于桩基础，可以缩短桩体长度及降低打深桩难度，降低基础工程成本，易于广泛应用。
